A naturopathic doctor offers tips for navigating the often contradictory and confusing world of modern human nutrition.
As soon as we start to feel comfortable with our grasp of human nutrition—which foods are healthy, which ones are unhealthy, and how to eat a balanced diet for optimal health—a new study gets published that shatters our once-felt sense of confidence.
Confusingly contradictory health claims constantly appear in the news, like the American Heart Association’s vilification of coconut oil. The vegan diet-promoting documentary What the Health, currently trending on Netflix, turns convention on it head by assuaging our fears of refined sugar, instead blaming animal protein, eggs and dairy for the worldwide diabetes epidemic. Even I find myself doubting the 15 years I’ve spent studying and working in the field of human health every time paradoxical nutritional data is uncovered.
When I was in high school, I remember patting myself on the back for choosing fat-free options, hoping the leanness of my food would encourage leanness of my flesh. I gave up meat, understanding that I was making a healthier choice; I was told that meat, fat and cholesterol were all culprits of heart disease. I tried giving up eggs and dairy, trying on veganism in order to minimize my impact on the environment. I did an elimination diet while at naturopathic medical school, removing gluten. When my colleagues started reading about the Paleo Diet—grains were the enemy all along, while meat was good for us—I slowly began to embrace a “primal” diet. I started removing myself from the influence of decades’ worth of poorly conducted research and began welcoming saturated fat back into my life. Fat was fine; it was carbs that were the root of all disease. Atkins had gotten it right from the beginning. Eventually I cut out all carbs and sugar and tried a ketogenic diet, eating lots of fat, moderate amounts of meat, and some vegetables.
My journey brings me here, to my Facebook newsfeed, which has been infiltrated with articles condemning coconut oil and saturated fat for raising LDL cholesterol and contributing to cardiovascular disease. “But I thought it was healthy!” Friends, family and patients cry, tearing their hair out in confusion over the news. Some patients have watched Netflix’s What the Health, a documentary from the makers of Cowspiracy, which asserts that sugar’s link to type II diabetes may not bas as strong as previously thought.
The flip-flopping is frustrating for sure, especially for those of us who are committed to living healthy lives for as long as possible. But before we toss our tubs of coconut oil and liquid stevia drops in the garbage and start pulling out the white sugar and margarine again, we should consider how nutritional research is conducted. Let’s entertain different traditional, holistic viewpoints on food and nutrition in order to learn how to feed our bodies optimally.
The Problem with Nutritional Research
There are several problems with how we study nutrition. One of the challenges lies within science itself; scientific studies, by their very nature, attempt to isolate all of life’s complexity down to two variables in order to study them while nutrition, as it’s practised in the day to day lives of human beings, consists of an infinite number of important factors that are often not taken into account.
Most human diet studies are epidemiological. Researchers follow populations of people for years, tracking what they eat and noting how many diseases they get over time. They then synthesize the data to create story. For instance, how much fibre did the people who had heart disease eat? Did those who avoided gluten have a higher risk of diabetes?
In order to assess dietary intake, most epidemiological studies use Food Frequency Questionnaires, or FFQs. Study participants are asked how often they eat certain foods (such as chicken) per week. They are asked to check a box, from “none” to “more than 6 times a week”. As a clinician interested in how my patients’ nutrition may be affecting their health, I assess diet in a few different ways. In the initial appointment, I ask my patients to recall everything they’ve consumed in the past 24 hours to get a rough overview of how they typically eat. Then, between the first and second appointments, I have my patients track their foods in a diet diary over the course of one to two weeks. The accuracy with which my patients report their food intake from the day before depends on their memories, perceptions, and diligence in recording, among other things, and this can compare drastically with their diet diaries that are recorded in real time. Not only do the mundane memories of daily meals evade us, we are often found guilty of deceiving ourselves based on how we feel we should be eating, rather than how we actually are. I find it hard to believe that participants are filling out FFQs accurately.
Also, the stories that epidemiological studies create from the data establish correlation, not causation. With many correlations (like one of my favourites: ice cream consumption and drowning—both occur in summer) there is often no direct relationship. If assessing the connection between fat intake and diabetes, a good study will take into account all meaningful variables, such as how often the participants exercised, or whether they had existing cardiovascular disease. However, considering all the possible factors that might effect the relationship is virtually impossible. For instance, what was the status of the gut flora of the participants? What was their antioxidant or mineral status; were they magnesium deficient? Were they consuming meat that was pasture-raised or corn-fed? How high was their daily toxic exposure? Did they experience chronic stress? How well were they sleeping? What were their levels of inflammation like? And so on.
The trouble with studying nutrition and disease is that, when it comes to health, context matters; context may be all that matters. For instance, while we know that barbecued meat can produce carcinogens that potentially lead to cancer, a study found that when the meats were seasoned with rosemary the carcinogenic load of the meat was neutralized. It’s nearly impossible to form a complete picture when we insist on studying isolated factors, leaving out many important details.
Animal studies, while allowing for tighter control (we don’t ask mice to report their diets, we just feed them), are also flawed. Firstly, mice and humans are completely different species with different nutrient requirements. However, animal study designs can also be problematic. Animals are given lard and white sugar to assess the effects of a high fat, high sugar diet on their health—their diets are exaggerated for the purpose of the study. Human beings, however, eat burgers, cake, and ice cream. We don’t eat single nutrients like fat and sugar, we eat food. If a mouse gets sick on a diet of lard and table sugar is it because of the foods it was eating, something he wasn’t eating, or some other unforeseen factor? There may be a huge difference between eating a high-fat diet with no vitamins and minerals, and eating a high-fat diet that contains complete nutrition.
A third method for studying human nutrition is through randomized control trials, or RCTs. In RCTs humans are randomized into a group that receives an intervention, like a dietary plan, or a control group that is told to follow some other diet or just eat normally. These trials control as many variables as possible, but the timeframe for these studies is often too short to garner meaningful information about health outcomes, which may take years to manifest. It is also difficult to get participants to stick to meal plans. Further, it’s hard to establish consensus for each diet being studied. For example, when assessing the nutritional merits of the Paleo diet, how many servings of vegetables should participants be told to consume? How many grams of fat? What types of fat?
It’s important that we can use studies to seek answers to our questions about the relationship between nutrition and health. However, due to its many limitations, nutritional research can only take us so far. This is why one study may indicate that high sugar diets contribute to diabetes risk, while another study finds no relationship.
A New Food Guide
If we can’t trust research studies to tell us what to eat, who do we trust? Surely we can’t rely on Canada’s Food Guide, with it’s outdated recommendations that simultaneously overemphasize grains and dairy, while continuing to uphold archaic views on fat. Primarily created in the 40’s to help Canadian families ration their food during the war, the Food Guide was not necessarily created to promote the optimal health of those who follow it.
Dr. Ray Cronise, a former NASA scientist, outlines a food pyramid in his paper to help organize food into nutrient content. I often borrow his pyramid to depict nutritional balance to my patients.
Ray’s pyramid is composed of four circles, three that form the base of the pyramid, forming the three main groups of macronutrients: protein, fat, and carbohydrates, and foods that are composed primarily of each. The circle at the top represents the foods that contain a higher number of micronutrients: vitamins and minerals, which are mainly non-starchy vegetables like leafy greens.
Protein-rich foods include meat and animal products, including fish, eggs and dairy. Fat-rich foods include nuts, seeds and oils like coconut oil, avocado and olives. Carbohydrate-rich foods include starchy vegetables like potatoes, grains, legumes and fruit. Ray concedes, however, that none of these foods are composed of a single macronutrient; animal products often contain a significant amount of fat; nuts and seeds also contain protein and carbohydrates; and legumes and grains contain some protein as well.
Ray points out that most diets, particularly the Standard American Diet, is bottom-heavy. North Americans generally over-consume macronutrient-rich foods that are higher in fats, carbs, proteins, and calories in general, and under-consume micronutrient-rich foods like fruits and vegetables. Because of this, North Americans consistently fail to meet the levels of vitamins, minerals and antioxidants essential for optimal bodily function.
It seems that even “healthy” diets tend to focus on the bottom of the pyramid, restricting certain groups of foods while making up the balance by over-emphasizing others. Paleo and low-carb dieters often fixate on the right side of the pyramid, including animal products, nuts and seeds, but avoiding grains and legumes, while vegan and vegetarian diets concentrate on the left side of the pyramid, eschewing all animal products and getting protein from grains, legumes and nuts instead.
One thing all healthy diets seem to emphasize, however, is fruit and vegetable consumption. When studying the merits of a vegan or paleo diet, it is the non-starchy, micronutrient-rich vegetables that may confer most of the health benefits, regardless of the carb, fat and protein content. Therefore, Ray recommends focusing on the top of his food pyramid, eating as many vegetables as possible, while eating a balance of foods from the base.
Since we rarely eat pyramids, I often depict this balance for my patients using a plate. I divide the plate into four quarters. One half of the plate is dedicated to colourful vegetables, with at least a full quarter dedicated to greens. The other two quarters of the plate are divided into starches: grains, legumes, tuberous vegetables, and proteins: meat, dairy, eggs, fish, or legumes. Oils and fats can be used to cook with or added to the meal in the form of avocados, nuts and seeds.
Listening to the Body as Guide
So, while Ray’s advice to eat as many green and colourful vegetable as we can while eating a balance of the foods at the bottom of the pyramid is sound, how can we establish what the right balance is for us? Many of us will have vastly different requirements for the macronutrients: carbs, fat and protein. My body has an energy demand that is different from that of my 6′ friend who lifts weights daily, or my 90-year old hypertensive, mainly sedentary Italian grandmother. As a naturopathic doctor, who believes in an individualized approach to health, I tend to reject top-down dietary recommendations that ignore the variabilities among people.
A friend of mine, having damaged his health through a string of restrictive dieting, argues that all food—even refined sugar and saturated fat—has a place in a healthy diet. He believes our bodies are designed to crave fat, protein and carbohydrates in ratios that promote optimal health. He writes in his book that we can eat whatever we want as long as we eat intuitively and avoid foods laden with “fake” flavours and processed oils, like corn oil, that confuse our internal cues and hunger signals. He also argues, like the filmmakers in the Netflix documentary, What the Health, that there is no evidence that refined sugar causes diabetes, and that diets based on avoidance of certain foods are detrimental for health.
While I’m not convinced that refined sugar deserves to be completely cleared of all charges, I agree that mindful and intuitive eating may be the key to maintaining balance. Healing with Whole Foods by Paul Pitchford places awareness and physical activity at the base of its Integrative Food Pyramid. The idea is that we need to first establish the foundations of movement and mindfulness before we begin to talk about food intake. As my friend says, perhaps the key is tuning in to our own internal physiological and emotional cues through mindfulness, paying attention to hunger and cravings, rather than measuring calories, carbs, protein, or fat grams.
Following our internal cues may be difficult, as the book TheDorito Affect outlines. The author points out how certain foods are engineered to override our hunger and satiation signals and monopolize our cravings, leading us to overeat. Therefore, if we’re going to follow our body’s signalling, mindfulness is a requirement, but so is following the advice of Michael Pollen, author of The Omnivore’s Dilemma, who famously tells us to “Eat food. Not too much. Mostly Plants.”
Pollen urges us to stick to foods that resemble something we might encounter in nature: eat foods our grandmothers would recognize; purchase foods that come from a plant, not foods that are made in one; and to stick to whole foods or packaged foods with five listed ingredients or less. Pollen also encourages us to cook and prepare as much of our own foods as possible. Do you have a craving for potato chips, ice cream, or dark chocolate? Feel free to indulge, as long as you make it yourself using the raw, natural ingredients. The theory is that, when the body is given clean, whole food, it regulates its hunger and satiety signals to communicate to you exactly what it needs.
Heal the Individual
When it comes to whole foods, I believe that there are no “good” or “bad” foods, generally speaking. Observational studies that examine how traditional societies ate suggest to us that saturated fat, animal protein, dietary cholesterol, and carbohydrates all have a place in a balanced diet. However, when it comes to diet, especially therapeutic diets, it’s my job to consider the individual and their health context: there are no good or bad foods, but some foods are better or worse for certain people, and some may even be better or worse for certain people at certain points along their health journeys.
When I am helping my patients calm inflammation, heal their digestive systems, clear their skin, or manage autoimmune disease, I often recommend identifying food sensitivities and eliminating those foods from the diet. Oftentimes these foods need to removed only temporarily, but sometimes foods may need to be removed indefinitely. Patients with insulin resistance, such as in the cases of obesity, PCOS, diabetes or metabolic syndrome, often do well on a low-carbohydrate diet to restore insulin sensitivity. Again, these anti-inflammatory, reduced-carbohydrate diets may only be required until hormonal balance is restored. Older adults concerned with promoting longevity, or patients undergoing cancer treatment, may do better restricting protein to lower their levels of growth factors, while athletes and stressed out adults may require higher amounts of protein to promote muscle building, or to synthesize mood-regulating neuro-chemicals. A woman who is stressed, depressed, exhausted and iron deficient may feel much better increasing her dietary intake of red meat to help regulate her nervous system. Another woman, with a family history of colon cancer, may do better avoiding it.
Endless factors need to be taken into account when we consider which dietary style is right for us. Our health goals, health status, nutrient status, digestive system health, immune system health, liver functioning, insulin sensitivity and hormone balance, levels of stress, toxic load and inflammation are just some of the things that I consider when making lifestyle recommendations for my patients. Lifestyle preferences, tradition, culture, religious backgrounds, cooking abilities, time constraints, and other factors, will also all play a role in our food choices and eating habits.
Our emotional connection to food and our ethics also matter. While veganism is certainly not a diet I recommend, if consuming animal products is out of line with one’s morals, then following a vegan diet may be the healthiest way for them to live in accordance his or her beliefs. Similarly, someone with a history of disordered eating may need to lift all food limitations, even junk food, in order to heal his or her relationship with food and hunger.
Investigations into the eating patterns of traditional societies tell us that human beings thrive on a variety of different diets. Optimizing diet for the individual goes beyond following the latest research or government and industry-funded health recommendations. It involves eating a variety of natural, whole foods, learning to pay attention to the body’s hunger signals, and even working with a health professional who uses diet to help promote health and manage disease on an individual level.
Current research suggest that gluten can increase systemic inflammation, contributing to a worsening of mental health symptoms, as well as other inflammatory conditions, such as pain and autoimmune disease.
Transcript:
Hello, you guys, my name is Dr. Talia Marcheggiani and I’m recording to you guys from my clinic in Bloor West Village. It’s call Bloor West Wellness Clinic, in Toronto, Ontario, Canada. And today, I’m going to talk to you guys about how a gluten sensitivity might be the underlying cause of your mental health conditions or other inflammatory conditions such as arthritis, migraines and digestive symptoms like IBS.
One of the reasons that I’m recording this video is because gluten is a really hot topic in the health and wellness industry and you’ve probably encountered your own versions of gluten-free food, or articles on the internet about how gluten is this evil toxin and there’s a lot of misconceptions around this and so I’m going to just talk a little bit about what gluten is and my own journey with cutting gluten out of my diet and how I came to that space where I was willing to do the experimentation and cut it out and see what my results were.
So, gluten isn’t a toxic substance per se, I mean there’s opinion around this in certain circles based on what it can do and how it affects the immune system and the results it can have on digestion, if you have sensitivity to it. But, what gluten is, is it’s a protein complex; it’s a bunch of proteins that are found in grains—wheat, rye and barley. And the protein complex consists of different proteins called gliadins. I might use gliadin and gluten interchangeably; it’s the same thing.
And, so, there is a health condition called Celiac Disease that’s a very serious health condition; it’s an autoimmune condition where the body attacks an enzyme called transglutaminase that’s involved in processing gliadin molecules. So this is not a reaction to gluten, per se, it’s an autoimmune reaction that’s caused by, that’s caused any time the body comes into contact with gliadin or gluten.
And celiac disease is a very serious health condition, it affects about 1% of the population, but there’s some room there for debate. So, some people think that you acquire celiac disease as you go on, and there’s evidence for that. And also, some people think that there’s a great underestimation of how many people are affected by celiac disease, that the number is higher than 1%, but that a lot of the cases do undetected.
And so celiac disease is diagnosed by blood tests. We’re looking at transglutaminase and endomysial antibodies, but the gold standard diagnosis is doing an intestinal biopsy. So, that’s how you find out if you have celiac disease, or not. So some people have done a blood test and they’ve tested negative for celiac disease, but are exhibiting some of the symptoms and so an intestinal biopsy will tell you yes or no definitively whether you have it or not.
Now, whether someone with celiac disease should avoid gluten or not isn’t really the debate here, I mean, that’s obvious. So, if you have celiac disease you have to avoid gluten 100%, it can’t be in your diet. You can’t even have a crumb of it. You have to use special toasters, or toaster bags, for your gluten-free toast. You have to make sure that your oatmeal hasn’t been contaminated by gluten. You can’t shop at Bulk Barn because there could be cross-contamination with gluten-containing substances. So, it’s almost like an allergy, you really have to be careful about coming into contact with gluten. And when people avoid gluten, if they have celiac disease, then that disease is managed.
So, whether someone with celiac should avoid gluten or not is not up for debate. What is is in this grey area, which is what you’ll be reading about online and that you’ll hear certain professional say is kind of myth, is this idea of non-celiac gluten sensitivity or gluten sensitivity. These are people who don’t have celiac disease, but for one reason or another notice that, when they take gluten out of their diet, they feel better. And when they reintroduce gluten they feel worse. And the symptoms are complex, just like in celiac disease. So, in celiac, people can get rashes, they can get joint pain, they can experience brain fog, they can experience brain damage, they can get arthritis, they can start getting other conditions such as thyroid conditions and so the symptoms are so wide-spread because of the inflammation that is triggered by eating gluten, and this is also the case with non-celiac gluten sensitivity—people who avoid gluten.
So, my story was that when I was a student at the naturopathic college, one of the things that I was exposed to in first year was this idea about elimination diets and leaky gut, which I’ll explain in a bit more depth, but you might have heard me write or talk about leaky gut. And, this idea that things like gluten or dairy could be contributing to some symptoms that I was experiencing and that a lot of patients were experiencing, and that taking these foods out in a systematic fashion, so doing a really clean diet, or a “hypoallergenic diet”, or a diet that’s basically chicken, rice and maybe some spinach, that that would heal a lot of the complaints that I and many others were experiencing, but that probably gluten was implicated in that.
So I was really resistant to this for at least two years. So, I wasn’t an early adopter at all to this idea, a lot of my classmates got the information, they went out and they started eliminating a lot of these foods from their pantries and they tried eliminations just for fun—well, for fun and also to experiment and to heal themselves and to “walk the talk”, as we say. But, I was living with my Italian grandmother and I would have toast for breakfast, I’d have pasta for probably lunch and dinner. I was getting gluten in my diet a lot and the idea of taking it out and resisting those familial pressures was—I just didn’t want to deal with it.
But, throughout the first couple of years of school I was also getting migraines on an almost weekly basis. And these migraines would take me out for the entire day. So, for the entire day I’d be throwing up, lying in the dark with a cloth on my head, trying to take some Advil, or something to mitigate it, but this was a chronic thing that I was going through.
Best case scenario, I’d get these once a month, but they were things that I was getting often. And I also had this life-long problem with bloating, these kind of IBS symptoms, like gas and bloating and, when I first started the naturopathic college, it was amazing to me that that was something we were talking about, because I’d kind of written that off as just being something, a peculiarity or particularity about my body that I’d just have to live with and it didn’t even occur to me that something that wasn’t considered a “disease”, per se, could be something that warranted attention and that had a treatment that went along with it, and a cause.
So I was kind of intrigued by that idea, like “oh, you mean I don’t need to be bloated?” and that, even though I’m not sick, like I’m healthy, I don’t have a disease, I don’t have high cholesterol or some of autoimmune disease, or type one diabetes, or something like that, but that the idea that an imbalance, or symptoms that were uncomfortable could be treated was totally new and exciting for me.
And so there was this intrigue in being gluten-free, but also this resistance to it.
And then, I think I was at a talk at school where we were given—it was sort of an information session, we were given free samples of a 7-day detox that involved shakes. And so, I did that because I had this free box, probably worth about $80 and I just decided, “ok, well I’m going to do this detox, it will be good for me. It will be sort of my introduction to eliminating a lot of these foods. It’ll be easy.” And it was really difficult. The first two days I had massive headaches as I was withdrawing from a lot of the things I was addicted to, such as caffeine, sugar and, probably, gluten, as well. But that sort of set the stage because I felt a lot better after that process, even after only that week of eliminating the foods. And so, when I started introducing the things I was eating normally back in, such as pasta and bread, I felt a lot worse. So, that discrepancy kind of woke me up to the idea that maybe these foods aren’t that great for me. And then I began a process of elimination and noticed really good results. I mean I don’t get migraines any more. It’s very very rare, and it’ll be a combination of weather and other factors and stress and overwork. But, that once-a-week, or even once-a-month, being in the dark with a cloth on my head, no noise and vomiting all day: that’s in the past. And now when I reintroduce gluten I can maybe tolerate a bit of it, but I definitely notice a difference in my energy levels, in my digestion, and just in my mental functioning and in my mood when I make a habit of having it more often. So, I’m basically grain and gluten-free and have been so for about 4 or 5 years.
So, why is gluten bad? Why gluten? Why is that an issue? The obvious answer is that it’s so present in our society. So, in North America, gluten is one of the main staples in our diets. So, pasta for lunch, bread or a sandwich for dinner, and toast for breakfast, or cereal. We’re getting gluten as a main source in our diet, in wheat, very often. And so, when we’re exposed to certain foods continually, we become more susceptible to an immune response against those foods.
But also, gluten has, we see in the mechanism of celiac disease, there are these, this genetic predisposition to react to gluten. And so on immune cells, and we know that our digestive system is the gateway between our bodies and the external environment. And so, how our immune system kind of “educates” itself is by sampling things from the environment and deciding what’s us—and we shouldn’t attack ourselves, because that creates an autoimmune issue—what’s us, what’s ourselves and what’s food, what’s useful to the body, what’s supposed to be incorporated into the body as fuel—and what is not helpful for the body, what is toxic, what is foreign, and what we need to defend against, like bacteria and viruses.
So, our digestive system is kind of involved in sampling from the environment, deciding and showing those pieces of the environment to the immune system, and letting the immune system decide what it’s going to do about these things.
So, when we’re eating foods we’re kind of presenting them to the immune system. And our immune cells have different receptors, so they’re called receptors, but they’re sort of like, you can describe them as like locks for keys or little sort of antennae that feel out the environment. And so people with the receptors, HLA-DQ2 and HLA-DQ8 receptors, on their immune cells, those people tend to react and to connect those receptors with gliadin molecules, so gluten molecules, and that signals an immune response from the body. And when the body thinks it’s come into contact with something that it needs to trigger an immune response against, so that means something foreign, something threatening to us and to our health, then a whole inflammatory pathway starts to take place.
So, think about when you get a cold. You come into contact with the virus and the reason that that virus doesn’t kill us is because our immune system reacts to it. When you get a cold, depending on what virus you’re in contact with, you might get the swollen throat, and the pain, and maybe a fever, and maybe some mucus production, some runny nose. You might feel tired because it takes a lot of energy to mount an immune response like that.
So, when we’re experiencing inflammation, it’s really useful for us, because we’re killing off the things that could kill us, basically we’re at war with something from our environment, but it also doesn’t feel great to be in that state. And so we get into trouble when we’re in an inflammatory state and it’s not for the right reasons, like that we’re trying to attack something (acutely) and get rid of it.
So, a lot of people have these receptors. So even though only 1% of people react to gluten in the sense of celiac disease, about 30% of people express these HLA-DQ2/8 receptors on their immune cells. And so, coming into contact with gluten on a regular basis could be problematic for these people and it could trigger some inflammation.
Another thing that gluten does is create a leaky gut situation. So, I’ve talked about leaky gut before. Our intestinal cells, so our intestine is this long tube from our mouth to our anus, and it winds around and it goes from mouth to esophagus, to stomach, to small intestine, large intestine, and then rectum and anus, and different things happen along that process. And in our small intestine, we have these really long, they’re kind of like cylindrical cells. And, on one end, on the end that’s in contact with what we eat, there’s these little fingers, these villi that reach out into the environment and that maximizes our ability to absorb the things that good for us—the foods that we eat. And, in between—so, the villi kind of control, ok we’re going to break down the carbs, and we’re going to break down the amino acids, from proteins and we’re going to break down the fatty acids, and we’re going to absorb all of the ions and the minerals and the vitamins and we’re going to control how we take them in. We’re also going to control how we take in foreign substances, because we’re going to, remember, show them to the immune system and say “take a look, this is what’s in our environment. This is what you guys might need to prepare yourselves to defend against if this becomes a problem for us.”
And so, we really control, tightly, what we’re taking in through our intestine. So our intestine doesn’t just want to open up the gates and let whatever is outside in, it’s got these really specialized mechanisms for letting certain things into the body. And, so, between these intestinal cells. You imagine these cylindrical cells, almost like a hand, with little fingers, and they’re lined up all along your intestine. And between them are something called tight junctions. And so those, they might become more or less permeable depending on the state of the gut, and that’s controlled by something called zonulin.
Zonulin will open up that permeability and let things in between the cells. And lower amounts of zonulin will maintain a more closed environment. And so one thing that gluten has been shown to do, or gliadin, is increase levels of zonulin, which opens up our intestine to the external environment. And think about the things we eat. Think about the things that swallow, by accident or intentionally, the things in our environment that are toxic, or giant pieces of protein from foods. So, protein in and of itself can cause an immune reaction. We have children that are deathly allergic to peanuts and other nuts.
So, it becomes problematic when we have all this stuff just entering our body. And so gluten opens up the gut to allow all these things to enter the body. And so we end up mounting an immune response to things that would otherwise be harmless to us, like dairy, or eggs, those kind of things that are actually nutritious and helpful for our bodies. So, we start to enter this state. When we’re in a leaky gut state we start to enter a state of inflammation. And inflammation has widespread effects. In my case it was migraines and bloating and digestive symptoms, a foggier mind, foggier brain and lower mood as well. And in some people it can be bipolar disorder. It could be worsening of symptoms on the autism spectrum. It could be depression and it could be anxiety. And when we’re in that inflammatory state we have higher amounts of something called, they’re like excitotoxins, or endotoxins. And so these are toxins like lipopolysaccharides, or LPS, as it’s most often referred to, that trigger anxiety, they activate the limbic system, they activate the amygdala; these are fear centres in our brain.
We also have something called the Blood Brain Barrier (BBB). And that’s really similar to the intestinal barrier with the tight junctions, and that prevents things from getting into our brain that are in our bloodstream. So, it’s like we have this second wall of defence because our brain is so important to our survival and fluctuations in our brain chemistry have really disastrous effects. So we have this extra sort of layer called the BBB that prevents things from getting into our brain. And when we’re in a high inflammatory state, like when we’re exposed to gluten, we get these cross-reactions where what keeps our blood brain barrier intact starts to separate, so we get this leaky brain picture. So we’ve got a leaky gut and also a leaky brain happening. And so we’re getting these toxins, and we’re getting inflammatory mediators entering the brain.
And more research into depression and other mental health conditions has shown that inflammation might play a giant role in low mood. There was one study done with patient who were hospitalized for bipolar disorder. So, these were people who were in a psychiatric facility. And they measure their blood for antibodies against gliadin. And they found that there were elevated antibodies in these people. So, there wasn’t a control group, they weren’t testing against non-bipolar, or people that didn’t have a bipolar diagnosis, but they found that every single patient, who was diagnosed with bipolar disorder and was hospitalized, so their symptoms were severe enough to require hospitalization, had elevated levels of antibodies to gliadin. Then they retested them some time later and found that having high levels of gliadin, or even further rises in gliadin antibodies, predicted whether they were rehospitalized. So, we can infer from that that their symptoms worsened. And so we know that there is this connection between mental health conditions, you know, depression and anxiety and bipolar and even psychosis (and gluten sensitivity). Another study showed that there were high levels of antibodies in people who had psychosis and psychotic symptoms.
So, we know that there is this connection with mental health and with inflammation and that this inflammation can be worsened by a gluten sensitivity or gluten reactivity and that maybe 30% or more of people are susceptible to reacting to gluten in some kind of way. And that gluten just in and of itself might cause this leaky brain situation or leaky gut situation. So, one thing I do is that I don’t do this with every single patient that I see who comes in with depression or anxiety or stress. I mean I don’t jump right into prying gluten from their hands, because my own experience was that it took me literally two years to think about removing it and I had to come to it on my own. But, I might plant the seed, or we might do something like a trial run. Especially someone who’s got mental health symptoms, or is coming to me for mental wellness, and they also have digestive symptoms. I mean, those two things together are a clue that doing some elimination diet, or some leaky gut healing or removing foods like gluten could be a good idea.
But I might present the option to them. We find that most treatment does really need to have 100% compliance rate. So, some patients will come back and say, “you know, I kind of took gluten out, maybe 70-80%” and that’s really great, because I think that it sort of sets the stage for creating a gluten-free lifestyle and doing a gluten-free trial, but really what the research is showing is that we need to 100% take it out to allow the gut healing and the brain healing to occur and to lower those inflammatory mediators.
But, the good news is that it usually takes about 2 to 4 weeks to get symptoms to really come down. So, it’s not like you’re on this trial for life and you can go back to your pasta—if you don’t notice any change after 2 to 4 weeks, at all, then you can go back to your pasta with the peace of mind that this isn’t an issue for you. But, if you do notice some improvement after removing it, then it is something that we can investigate either down the line, when you’re ready, or something that you might want to consider. It’s sort of like planting that seed. But, I don’t pry out of my patients’ kicking and screaming hands. It will be something that we might work on down the road, and something that is always kind of on the table or on the back burner for future attempts and experimentation.
And so, the gold standard, when it comes to treating gluten sensitivity, is just to do an elimination, so take gluten out of your diet for about a month, 100% out, as best you can. There are blood tests that you can do and those can show an elevated antibody response to gluten or gliadin or wheat as well as other foods. The one I do on my patients looks at about 120 different foods. And this is great because having a piece of paper that shows you what your immune system is dealing with in the moment that you got the blood work done is useful. And people tend to, when it’s a blood test, it tends to hold more authority than simply the subjectivity of symptoms. But, really, the best way to see how gluten affects you or how certain foods are affecting you in your immune system is to do an elimination diet, remove it 100% from your diet, give your body some time to heal and then reintroduce it and see what it does to you once you’ve healed from the state that it’s put you in.
Doing that removal is important because the antibodies are only one part of the immune system and so when I’ve done a food sensitivity test on myself, I felt crappy because you have to eat the food for a while. So I was reintroducing gluten into my diet and I didn’t have a high gluten antibody. I had antibodies to other foods, but not gluten. So I kind of psychologically was like, “well, I guess I’m ok to eat it, then.” And went back to eating it a bit more regularly and then experienced really terrible symptoms and my mental health took a decline and then I had to take it out again.
So, the labs don’t necessarily tell the whole story. What does tell the whole story are your symptoms. So, taking gluten out for 2 or 4 weeks is what I recommend most people do. And, so how do you take it out? So, really what the goal is, because, and I’m saying this piece now because there were some articles that were floating around, it was a few months ago, but I’m sure they’re still around, that said, “going gluten-free is unhealthy. It’s dangerous.” And I was really confused by that because I was like, it’s not like wheat is this really important food in our diet that’s giving us all kind of nutrients. We fortify grains with things like folic acid and other B vitamins, like riboflavin. But, they’re not super nutritionally dense, and it’s not like we have a calorie deficiency where we need to get more carbs and calories. I’m not telling people to avoid spinach, or something that is really giving them a lot of nutritional currency, so why would it be harmful to take gluten out?
And then I realized how it’s often being taken out. So, you go to the grocery store and you find that there’s a whole gluten-free section. They basically have gluten-free breads or gluten-free Oreo cookies. And those gluten-free Oreo cookies are for, like, celiac children that want to join in with the rest of the group. They’re not like, “oh, I’m eating these gluten-free Oreo cookies. These are a healthy choice that I’m making.” It’s a substitute for a junky food. You’re substituting one junky food for another junky food, but the only thing is that you’re still maintaining your gluten-free status while on the substitution.
And when it comes to gluten-free breads vs. whole grain breads or whole wheat breads. Probably whole wheat breads have more nutritional bang for their buck; they’re higher in fibre, they have more nutrients. And gluten is a protein, which is what causes the immune system reactivity that it does, but if you don’t react to proteins, they’re healthy for us and we need them, because they contain the amino acids and they fill us up, and they do all the other things that proteins from other foods do. So, usually gluten-free bread doesn’t have very many proteins in it.
So, yeah, if you’re choosing between nutritional value of a gluten-free bread versus a whole wheat bread, then the whole wheat bread is better for you. So, we see this in people that do gluten eliminations and they’re kind of like, ok I’m going to take my wheat pasta and I’m going to have rice pasta instead. I’m going to take my gluten-free toast in the morning, or my gluten toast, my wheat toast in the morning and have gluten-free toast instead. So, that’s not the healthiest way to go about it. It might be a good way to transition when you’re trying to do an elimination. It gives you peace of mind, it allows you to still have your Oreos. It’s not creating a giant change, then that could be helpful. But really what we’re aiming to do is not just substitute wheat products, or gluten-containing products, for non-gluten-containing products and leave it at that, we’re trying to shift into a more traditional diet, like a Mediterranean diet or a Paleo diet, that’s higher in the fruits and the vegetables, and that’s higher in the healthy fats and that’s more protein-rich, and that the proteins are from better, cleaner sources. So, that’s the end goal. So, it’s not that we’re happy with patients eating rice flour and tapioca bread. It’s about switching to a cleaner and more sustainable diet that our bodies evolved to thrive on.
However, the immuno-reactivity of gluten is really what we’re trying to deal with when we’re going on a gluten-free diet, especially the 2 to 4 week trial run. And so what you’re doing on that 2 to 4 week period that’s allowing you to stay on gluten, if that involves gluten-free rice bread, then that’s another story and I think, as a naturopathic doctor working with people who are struggling to get rid of gluten and see if that’s an issue for them, I think that’s ok for the short term.
So, it’s not that going off gluten is bad for you, it’s how we do it. Are we changing our habits for better ones or are we kind of sustaining some of the same Standard North American Diet habits and just cutting the gluten out and thinking that that’s healthy for us, or that that’s going to cause weight loss, or whatever.
No, this is a different thing that I’m talking about. I’m talking about gluten as a root cause of inflammation that then leads to psychiatric disorders, such as bipolar, depression, and anxiety.
And, so one thing I’m going to say as well is that sometimes it’s not enough just to take out gluten and so what I do—or other foods that are suspect, right, so dairy could be another culprit in this or things like eggs, or soy. There’s many things that we could react to. But we often start with gluten. So, often taking the food out isn’t enough and we need to do some gut healing with things like l-glutamine, which I mention in my amino acid talk and also restoring the probiotic balance and doing some things that are just helping repair the gut, getting digestion back on track, getting your digestive motility moving through things like digestive enzymes and bitter herbs and things that like. And so, I’m just going to mention three probiotics that have been shown—they’re called “psychobiotics”. They’re nicknamed that because of the beneficial effects on mental health and in another lecture I was also talking about how the probiotics in our gut are also responsible for producing serotonin that our body has available to it, which we know is the “happy hormone”, that’s what the selective serotonin re-uptake inhibitors work on. So, getting the right balance of bugs in your gut could be just as effective, potentially, as taking an antidepressant medication. So, that’s really cool. But the three bugs that a lot of research has been done on are the Lactobacillus casei, Bifidobacteria longum and Lactobacillus helveticus, which has been shown in studies to actually decrease anxiety and to lower levels of cortisol, which we know is also implicated in depression and anxiety and probably other more serious psychiatric disorders.
So, I hope that was enlightening. We talked about how gluten can contribute to inflammation, leaky gut and thereby exacerbate or create mental health issues. How going gluten-free is not the same as going “whole foods” and how going gluten-free might be the answer or at least a part of your self-care process in healing from mental health conditions.
Thanks a lot, guys. I hope you’re having a good New Year, a good 2017, and I’ll see you soon.

I’m tired of hearing mental health conditions blamed on a “chemical imbalance”. Patients everywhere are being told that their mental health conditions are, literally, “all in their heads”. With this diagnosis—often distributed insensitively, and without much attention to the complex factors in thoughts, beliefs, emotions, the environment, biology, nutritional status, mental and emotional as well as physical stressors, and life circumstances (just to name a few) that can contribute to mental health imbalances—patients are left with the message that they are somehow damaged, broken, or that their condition arose out of an inherent weakness that they somehow possess. Through the numerous conversations I’ve had with those struggling with mental health symptoms, I have come to understand that oftentimes there are phrases that rob power more than the term “brain/chemical imbalance”.
Fortunately, there is still more to emerge in the wonderful world of science. Very little actual evidence supports the chemical imbalance theory of depression and researchers and clinicians alike are forced to admit that symptoms of conditions such as depression and anxiety are often the result of multiple factors that come together. Contrary to the common narrative of mental illness being a sign of weakness, evolutionary biologists are uncovering evidence that symptoms of depression might be the result of a highly adaptive strength based on preserving the body during times of great mental, emotional and physiological stress—showing, in fact, that depression and anxiety might in fact be afflictions of the strong, not the weak.
In my practice, I approach depression and anxiety from a functional medicine standpoint. This means, simply, that I look not at the title of the condition my patients come in with (I care very little if you have depression, or anxiety, or bipolar disorder, etc.—the name is not the thing itself), but how the condition occurs uniquely for them. By paying close attention to the multitude of symptoms, thoughts, and factors that influence the mood and emotions, I am able to uncover underlying pathways that point to imbalance in the body and dig up the roots from where the symptoms might have arisen in the first place. Through this method, focussing on the functioning of the body rather than it’s pathology, we’re able to bring the body back into a state of balance and reverse symptoms permanently, rather than simply slapping a band-aid over them.
When it comes to mental health, it is important to emphasize that depression and anxiety (as well as other mental health diagnoses) are not diseases at all; they are symptoms. When presented with low mood, feelings of sadness and worthlessness, lack of motivation, lethargy, brain fog, changes in appetite and weight, abysmal self-esteem and so on—all symptoms that many patients with depression face—we need to follow the threads of symptoms back to the point where things began unraveling. It is necessary to backtrack to the biological imbalances where symptoms first began.
There is an overwhelming amount of research coming out in the field of mental health that links the gut and digestive health to mental health symptoms, indicating that depression might not be a brain chemical imbalance at all, but a gut chemical imbalance. Where there is depression and anxiety, there is more often than not, a digestive issue.
We have always known that the digestive track and brain have an intimate bond. From the vagus nerve that enervates the gut and begins in the cranium, to the mood-regulating neurotransmitters that are created in the gut, we all have the experienced the tummy aches linked to grief or the power of anxiety to loosen our bowels. We’ve all noted the phenomenon that great ideas or moments of clarity seem to spontaneously arise from, not the brain, where we always assumed our thoughts were formed, but the gut (hence the term, “gut feeling”, which we use to characterize intuitive insights).
When it comes to issues with the brain—thoughts, moods, emotions, feelings, etc., where else should we look for answers than our brain’s close cousin, friend and confidant, the gut. Mental health symptoms can arise from impaired digestion in a number of ways:
A failure of the gut cells (enterocytes) to create neurotransmitters. The majority of serotonin (the “Happy Hormone”) is produced in the gut. Inflamed and unhappy gut cells are often unable to make serotonin.
An imbalance in the healthy gut bacteria that influences whole-body health. We have 10x more cells in our gut than in our body in the form of almost 5 lbs of symbiotic gut bacteria. This bacteria ensures our well-being by helping us digest our food, soothing inflammation, educating our immune system, killing off harmful pathogens, creating bulk for our stools and, relevant to the field of mental health, producing neurotransmitters important for regulating mood, such as serotonin and dopamine.
Research has gone into the connection between a low-level of inflammation in the brain and its affect on mood. Inflammation is usually a product of our diet, stress and food sensitivities. In naturopathic medicine and functional medicine we treat inflammation with the assumption that nearly all inflammation begins in the gut. A condition called “Leaky Gut” is a failure of the important seal between the intestinal walls and the rest of the body. When this seal is broken, toxins, proteins and other debris are free to enter the bloodstream, wrecking havoc, setting the immune system off course and, eventually, triggering symptoms of inflammation, autoimmunity and mental health issues.
Our body requires many building blocks to maintain its complex fortress. Difficulties in the digestive cells’ ability to absorb essential fats, amino acids and vitamins required for brain health, hormone regulation, detoxification and immunity, among the thousands of other chemical reactions in the body, will result in impairment in overall functional. Nutrient deficiencies are more common, even in developed societies, than one might think. Deficiencies arise from: impaired absorption, inadequate diet, increased amounts of stress and the ingestion of foods or medications the deplete the body of nutrients. In any case, optimizing the gut’s ability to digest and absorb the nutrients we’re either eating or supplementing is key for improving health and mood.
When it comes to understanding mental health issues I, as a clinician, realize it is hardly ever just one factor involved. Properly helping someone with anxiety or depression heal involves understanding the constellation of potential causes and how they inter-connect and relate to one another. Through this detective work, we can begin the journey of unraveling the imbalances and restoring the body’s ability to function and heal.
Treatment plans usually involve a combination of replenishing essential nutrients that patients are deficient in (deficiency can be detected through blood work, health history or symptoms), repairing the gut’s ability to absorb, restoring the body’s balance of healthy gut bacteria, removing food sensitivities and healing digestive inflammation, balancing hormones, and managing lifestyle stress and environmental factors that may be contributing to low mood.
My patients make impressive commitments to healing and are willing to examine their bodies and past experiences, in order to do the hard work of healing. Beyond my role as a doctor, I am committed to working as a facilitator, teacher and guide. My job is not to tell people the right path to walk, but to help them understand their body’s complex language, listen to the signals and messages that arise from it, and understand what those signals are asking of them.
Healing the digestive system requires patience, curiosity, and a willingness to engage deeply with the body’s needs. The digestive tract is intricately connected to every other system in the body, including the immune system, the nervous system, and even emotional well-being. A skilled gastroenterologist can be a crucial ally in unraveling the complex interplay between these systems, identifying imbalances, and guiding patients toward solutions that honor their unique experiences. Together, we can pinpoint the underlying causes of digestive distress, whether it’s nutrient malabsorption, bacterial overgrowth, or a deeper reaction to life’s stresses, and begin the work of true healing.

The gut-brain connection has gotten the attention of researchers and functional medical practitioners. I discuss, briefly, what research has shown us in regards to the complex realm of the microbiome and how depression may be a result of inflammation in the brain, stemming from inflammation in the gut.
My name is Dr. Talia Marcheggiani and I am a naturopathic doctor and mental health expert in Toronto.
Today we’re going to talk about the gut-brain connection and how that can influence your mental health symptoms.
I think we intuitively know that the gut and brain are connected. When you feel mental symptoms of anxiety we immediately notice the effects on our gut.
During times of stress, we know that we have indigestion, we’re more predisposed to things like diarrhea and irritable bowel syndrome.
Even anatomically there’s a nerve, called the Vagus nerve, that directly connects the brain to our digestive system.
This nerve is responsible for putting into that “rest and digest” state.
When this nerve is stimulated, our bodies start to secrete digestive enzymes, saliva starts to be secreted and we’re able to break down our food and absorb the nutrients from the food that we’re eating.
A lot of research has been going on, that you might be aware of, about healthy gut bacteria. And more and more people, especially medical doctors, happily, are prescribing probiotics anytime someone is prescribed antibiotics for a bacterial infection.
Scientists have started to study more about these gut bacteria. We know we have, like, 5 lbs of gut bacteria, sitting in our digestive systems. Over 100 trillion cells, this is more than 10x the amount of cells we have in our physical bodies, and more DNA than we have in our body.
We’re more bacteria than we are human!
And these gut bacteria, we can’t survive without without them, they influence the very physiology we experience and they definitely impact our health.
These bacteria are responsible for helping us digest our food, and for our mental and emotional wellness as well as keeping our immune system in check.
So, a disbalance in bacteria, or an increase in that negative, bad bacteria and not good strains of healthy bacteria, can lead to diseases like autoimmune disease or multiple sclerosis, or things like chronic fatigue syndrome as we’re seeing in research.
Scientists are starting to study more about how the bacterial balance in our gut can influence our mood and mental health.
These gut bacteria can actually produce serotonin. So that’s the happy hormone in the brain. And you may have heard of serotonin, especially if you suffer from depression or anxiety because your doctor might have recommended a kind of medication called SSRIs, or Selective Serotonin Reuptake Inhibitors, or a similar drug, SNRIs, like Venlafaxine, which is a Selective Serotonin and Norepinephrine Reuptake inhibitors.
This is based on on the Monoamine Hypothesis that there is this chemical imbalance in the brain. That your body is either not making enough, or absorbing enough or reacting to serotonin enough.
When we’re given these antidepressants, the idea is that we’re recorrecting this brain imbalance and that’s as much of the story as we’ve got. We don’t know why these brain imbalances are around.
So I think that, if we’re going to stick with this hypothesis, which is still controversial in science, we should look to the gut bacteria because we know that gut bacteria produces a significant amount of serotonin and, if we’re blaming depression and anxiety on serotonin deficiencies, why not look at the gut and find out how we can influence the balance of healthy gut bacteria so that we’re producing enough serotonin. Especially if we’re relying on drugs to correct the imbalance and we don’t have enough serotonin for the drugs to work properly.
Gut cells on their own produce 95% of the serotonin in the body so basically every single chemical that we have in our brain is produced or exists in the gut.
So, we need to be able to feed the gut cells so that they’re producing healthy amount of hormone we need to experience a healthy mood and live our lives in ways that are stress-free and energized and happy so that we can effective in our lives.
Mentally and emotionally, you might know this “gut feeling” that we talk about in language and that’s kind of permeated throughout cultures. So, we know that when we have this feeling in the gut that, it’s almost like an intuition. Some people will say, “I just knew it, because I felt it in my gut.” And I think that we’ve always had this intuition. We’ve always had this connection between what our mental state, our thoughts, beliefs and emotions are telling us and what our gut is telling us.
We think that we think with our brains and that all of the mental symptoms we experience are happening at the level of the brain, but because of this tight gut-brain connection, we know that’s not true.
People that have done brain studies actually find that we have thoughts before we have brain activity a lot of the time so, I wonder if we’re actually thinking with our gut, which is a revolutionary and radical thought, but we’re finding more and more evidence for this in science.
You may have heard of the condition called “Leaky Gut” or the more official, scientific term is “Intestinal Permeability”. Our gut is really selective about what it absorbs for good reason. What happens, though, when we’re experiencing chronic stress, or we use a lot of antibiotics or maybe eat things like high-sugar foods, caffeine, or a lot of alcohol, we can cause gut inflammation, which starts to allow bacteria, food toxins, or whole proteins from food into the blood, into the body by breaking down the integrity of the gut.
So, when it comes to health, for most health conditions, especially when there’s a few symptoms that seem disconnected and it’s hard to find the relationship between them, naturopathic medicine and, now, functional medicine and, hopefully soon, conventional medicine, begins to look at gut health.
So if I’m sitting across from a patient who has a long list of health symptoms that seems like they’re not connected and has digestive symptoms—and 40-60% of the population, in general has some kind of digestive symptom, whether it be bloating after eating, feeling fatigued after eating, just feeling like your food is sitting in your stomach and not really moving through, GERD, so acid reflux, heartburn, diarrhea and constipation, or those IBS symptoms, gas and bloating—when I sit across from a patient with any of those symptoms, the first place we go, in terms of treatment, is to look at the gut.
So how do you keep your gut healthy? There’s a few things. The first is to eliminate anything that’s causing gut inflammation, so this could be excessive caffeine and alcohol, excessive refined sugars, antibiotics without doing a probiotic immediately after or during an antibiotic treatment, chronic mental and emotional stress, or physical stress, and food sensitivities: something we’re eating that’s causing our immune system to react and our gut to become inflamed.
Ensuring a proper bacterial balance by either supplementing with a probiotic or eating a variety of fermented foods such as kefir, yogurt, kombucha or saurkraut, and making sure that we’re eating a variety of whole foods: whole grains, fruits and vegetables, and healthy fibres that are going to feed that healthy gut bacteria.
So, when it comes to mental health, such as depression and anxiety, chronic mental stress, even things like bipolar, OCD, conventional medicine tends to just look at the brain and blame the brain on the host of symptoms that patients might experience.
Naturopathic medicine looks at the entire body. And since we know that the gut and brain are connected, and our patients are simultaneously experiencing mental health symptoms and digestive symptoms, we definitely have to treat the gut.

I work at Bloor West Wellness Clinic in Bloor West Village, in Toronto.
This is a common story that can describe any number of patients I see in my private practice: My patient has been doing well–she’s been exercising regularly; she’s been cutting out sugar and processed foods and watching what she eats. She’s been having salads for lunch. She’s even gotten her husband on board! He’s started to have salads for lunch with his cheeseburger (instead of fries) and given up having a row of cookies in the evening. All things considered, she’s been doing great. However, despite her best efforts, after one month of tiresome slog, restriction and dedication, she’s only managed to lose a few pounds. Her husband? He’s lost 10.
“He has more to lose,” I suggest to her. “Those few pounds you’ve lost are gone for life—slow and steady stays off forever.” I am her cheerleader, but the truth is: hormones, especially when it comes to women.
Hormones are the body’s telegrams. They are produced in glands in tissue like the gut, ovaries, adrenals and brain and act on distant cells in the body, telling them how to behave. When it comes to weight loss, hormones can be the culprit if diet and exercise have failed to produce results. Hormones control appetite, mood, food cravings, metabolic rate, fat gain and distribution and hunger, among other things. Any hormonal imbalance will sabotage weight loss efforts and it’s often the first place I look when a patient has weight loss goals that they aren’t achieving with diet and exercise alone.
The Players:
There are numerous hormones in the body that are responsible for the above actions, however the main ones that we can affect through diet and lifestyle are insulin, cortisol, estrogen and the thyroid hormones. These are just some key players in a team, however just by working on these four, we can start to see results.
Interconnectedness:
Hormones are complex entities, not only for the wide array of effects, but for their tendency to effect the action of each other. For example, high cortisol can effect levels of estrogen, insulin and the thyroid hormones. High insulin can affect cortisol and estrogen. And so on. Working on hormones is like attacking a giant knot and often requires starting from the basics: diet and lifestyle.
Insulin Imbalance:
Insulin is an important hormone in the body—we can’t live without it. Released by the pancreas after a carbohydrate-rich meal in response to rising levels of sugar in the blood, insulin gets sugar into cells where it can be used as fuel. It also brings down blood sugar, making it a main culprit in hypoglycemic crashes and sugar cravings. The problem with insulin, however, is when we overeat carbohydrates and sugar, we overuse the insulin response. The result is abdominal fat, weight gain (insulin tells the body to store fat), a blood sugar roller coaster, mood swings (that “hangry” feeling) and intense sugar cravings and energy crashes.
Balancing Insulin:
Insulin is best balanced by diet, particularly managing carbohydrate intake and emphasizing healthy fats and protein in the diet. Fat and protein slow sugar absorption. This prevents a rise in blood sugar and decreases the need for insulin. The result is feeling satiated for longer, having stable energy and decreasing food cravings.
Morning protein:
The first step in balancing insulin release is to increase morning protein. I recommend aiming for 30 g of good quality, lean protein for breakfast like a chicken breast, or scoop of whey isolate protein powder in a whole foods smoothie. I was once accused jokingly of “not knowing that breakfast is”, when recommending chicken breasts for breakfast. However, perhaps it’s North America that has a skewed sense of what makes a decent morning meal. If the aim of breakfast is to break the fast that you’ve had throughout the night, then starting it off with a high-carb, high-sugar, nutrient-sparse piece of toast or bowl of breakfast cereal seems crazy to me. In Colombia and India, two places I’ve spent some time, we started off the day with a protein-rich stew or meat soup.
To balance insulin make sure that every meal, even snacks, contain some form of protein or a fat. Avoid eating carbohydrates by themselves and keep servings of carbs to a minimum and in their unprocessed, whole form (like large flake oats, quinoa and brown rice as opposed to flours or cereals).
Cortisol Imbalance:
One of the main hormone imbalances I notice when it comes to stubborn weight gain is cortisol imbalance. Cortisol is the stress hormone. It’s released by the adrenal glands, two pyramid-shaped endocrine glands that sit on top of the kidneys, in response to stress. Animals have two modes of operation: fight or flight or rest and digest. Cortisol increases blood sugar and alertness and tells the body to divert attention to gearing us up for combat or escape, and moves us away from investing energy in digestion, immunity and concentration. Cortisol is a wonderful hormone; it keeps us awake, and makes us feel alert and well, priming us to be effective in our busy, stressful lives. However, our bodies weren’t made for long-term stress response and we spend most of our time in fight or flight mode.
Cortisol and blood sugar:
Cortisol raises blood sugar, causing insulin to be released. This starts us on a blood sugar roller coaster trip, leading to sugar cravings, energy crashes and storing fat.
Cortisol and fat distribution:
Cortisol doesn’t directly tell the body to store fat (it happens through other mechanisms that happen in response to high cortisol), but it does encourage fat redistribution. Cortisol tells the body to move fat from the hips and thighs and deposit in the abdomen, face and shoulders, leading to the sexy “Buffalo Hump”. We know that abdominal fat carries more health risks than fat in other areas of the body so this detail can be troublesome when it comes to long-term effects.
Cortisol and the thyroid:
Cortisol impacts the thyroid by preventing the conversion of T4 to the more active T3. T3 and T4 are important thyroid hormones that set the body’s metabolic rate, among other things.
Cortisol and the sex hormones:
Cortisol can lead to estrogen dominance by diverting resources away from estrogen and progesterone production. In menopause, this is particularly troublesome, as the body relies on the adrenal glands, rather than the ovaries, to produce the sex hormones. High cortisol can result in progesterone deficiency and estrogen dominance symptoms, which can negatively affect weight loss. Cortisol also causing accelerated aging and who wants that?
Cortisol Balancing:
The main thing when it comes to cortisol balancing is to Calm Down—or as I like to poignantly put it, Calm the F#$% Down. The way this is done is highly individualized. Some recommendations I have are: meditation, yoga, exploring acupuncture (a wonderful way to balance cortisol, among other things), journaling, taking a day off, re-evaluating priorities at work and at home, etc. Mainly, getting 7-9 hours of sleep a night is essential for managing the stress response.
Taking it easy:
When it comes to weight loss, I often notice that certain efforts hinder our progress. It’s important to keep caloric intake adequate—eating too few calories can stress the body out, causing cortisol release. It’s also important to manage exercise. While exercise can teach the body how to manage stress, it does produce cortisol in the short-term. Therefore it’s important to keep exercise short and intense. Weight-training, short bursts of cardio (no more than 20 minutes) and varying intensities with High Intensity Interval Training, Tabata or Crossfit, are the best choices for weight loss. Training for a marathon or long-distance bike race may be fun and fulfilling, but they are not the best choices for weight loss, as they prolong the stress response and can work against you, rather than in your favour.
When I have a patient who is intensely tracking what they eat and over-exercising my advice is often (and it’s not that well-received, as you can imagine) “Take it easy”. Easing up on exercise and relaxing calorie-counting may be hidden pieces in the weight loss game.
Herbs and supplements:
There are a variety of nutrients to take to support adrenal function. The main things to consider, with the advice and counsel of a trained naturopathic doctor are B-vitamins, magnesium and adaptogenic herbs (the help the body adapt to stress).
Estrogen Dominance:
Estrogen, actually a group of hormones, are female sex hormones. Their main job is to promote the expression of female sex characteristics, the growth of breast tissue and to control ovulation. Estrogen also causes body to fat to be distributed to the thighs, buttocks and lower abdomen. The problem with modern society is an imbalance in the two female sex hormones, estrogen and progesterone. Due to stress and toxic environmental estrogens, or xenoestrogens, among other things, modern women have more estrogen relative to progesterone in their bodies. The effects of this are numerous and include, stubborn weight gain in the thighs (the famed “saddlebags), cellulite, acne, PMS, painful menstrual periods, fibroids, hormonal conditions such as PCOS, and the occurrence of certain female cancers, especially breast cancer. Estrogen can also contribute significantly to anxiety symptoms.
Estrogen balancing:
Correcting estrogen dominance primarily involves supporting estrogen detox pathways in the liver. Chemicals such as I3C, DIIM and calcium-d-glucarate help increase the liver’s ability to clear foreign estrogens from the body. Supporting digestive health also allows us to remove estrogens—they are neutralized in the liver and eliminated through the colon. Leafy greens contain a high amount of these chemicals, so ensuring you get adequate amounts in your diet is important for estrogen metabolism. Ground flaxseed, rosemary and fish oil are also important nutrients for clearing excess estrogen from the body.
Reducing exposure:
Try to reduce exposure to foreign estrogens by avoiding the use of plastic bottles and plastic-lined cans, using natural skincare and body products and natural cleaning aids whenever possible. It’s also important to see a naturopathic doctor 2-4 times a year for a medically-assisted natural detoxification to clear the body of toxic estrogens.
Hypothyroidism:
The thyroid gland sits on the neck, just below the Adam’s Apple. It releases two hormones T4, and the more active T3. These hormones are responsible for setting the body’s metabolic rate—converting fat into heat and energy. Thyroid deficiency, or hypothyroidism is more common in our society than we think (naturopathic doctors have stricter criteria for laboratory reference ranges than conventional medicine—we look for signs of health, not disease). Conventional medicine deems hypothyroidism as having a TSH (thyroid stimulating hormone) level above 5—for this hormone, all you need to know is lower is better—however ND’s will start to treat the thyroid when symptoms are present and TSH is above 2.5. Symptoms of hypothyroidism are stubborn weight gain, constipation, feeling cold, fatigue, especially brain fog, weak memory, hair loss, dry skin and thinning of the eyebrows.
Supporting the thyroid:
The thyroid gland is a fragile organ, sensitive to inflammation and stress. When there is inflammation in the body, often caused by stress, diet or insulin resistance, the thyroid is the first gland to suffer. Most cases of hypothyroidism are autoimmune in nature. Therefore, naturopathic doctors aim to correct inflammation by prescribing an anti-inflammatory diet and looking for food sensitivities. When we identify food sensitivities (through specialized IgG antibody testing or an elimination diet) and remove them from the diet, we can focus on gut healing which treats inflammation and helps repair the thyroid.
Managing stress:
Low calorie diets have the effect of suppressing thyroid function, which leads to the yo-yo dieting effect. Avoid extremely low calorie diets, or opt for intermittent fasting or calorie-cycling instead. Aim for slow and steady weight loss so as not to harm metabolic rate, which makes weight loss more difficult in the long run.
I previously mentioned that cortisol can harm the thyroid and that hormones are interlinked. Cortisol prevents the conversion of T4 to the more active T3, which can slow metabolism.
Nutrients:
A deficiency in iodine, zinc, iron and selenium, among other nutrients, can negatively impact the thyroid. Talk your naturopathic doctor about testing and supplementation.
Summary:
What would a visit to a naturopathic doctor look like? When it comes to hormones, treatment is often complex as it targets the root cause of symptoms and involves detangling the complicated web of hormones that are at play. This can require some diagnostic detective work. A naturopathic doctor will take your complete health history, order labs and perform physical exams if necessary. A common treatment plan might look like this:
Sleep: 7-9 hours per night
Take stress seriously: sign up for a round of acupuncture, start meditation, do yoga, journal, etc.
Measure hormones via saliva: cortisol, testosterone, DHEA, estrogen, progesterone
Identify food sensitivities via an elimination diet or an IgG Food Panel that tests for antibodies to certain foods in the blood.
Correct nutritient deficiencies through diet and supplementation
Herbs for hormonal support: estrogen detoxification, thyroid support, gut healing, adrenal support, glucose control and blood sugar balancing.
Exercise: short, intense bursts that target muscle-building
Diet: high protein, especially in the morning, healthy fats, low carbs and eliminate sugar, processed foods and food sensitivities.

As far as Canada’s Food Guide to Healthy Eating is concerned, naturopathic doctors differ in their views. In terms of a general guideline, I believe that it does a pretty good job of promoting a healthy diet: focusing on fruits and vegetables, whole grains, nuts and seeds, meat and protein. It even suggests adding healthy oils to the diet and supplementing with vitamin D. Not bad. But, as they say in my family, “Close, but no cigar.” I have one piece of beef with the Food Guide, and it’s not the beef, but rather another cow product that offends me: the outrageously huge influence on dairy.
I never thought I’d enjoy ice cream again. During the 4 months I spent volunteering in Costa Rica, I became obsessed with ice cream. It wasn’t my fault; it seemed that the whole population was obsessed. At the end of a long work day, one could spot businessmen nursing a McDonald’s soft-serve cone, leaning their bodies back from the drips that threatened to send their suits to the dry cleaners early.
This obsession with ice cream, which is damp and cold, is probably not the best thing for people of Kapha constituion, but I knew very little about ayurvedic medicine back then. I also had no idea that one could be intolerant to dairy, which I now know that I am. My almost-daily ice cream treat contributed to a 40-pound weight gain in those 4 short months.
Its seems that, for most people, the hardest part of starting a new diet is figuring out what to eat for breakfast. To help some of my RSNC patients on the road to hypoallergenic, healthier living, I compiled this handout to give them some inspiration for the most important meal of the day. These breakfasts might be appropriate for some on the elimination diet, but since each diet is different, make sure you review the ingredients first to verify that the recipe fits your dietary needs.
So, your naturopathic doctor or 4th year intern has suggested that you do a 3-6 week elimination diet? While at this stage it might seem like a daunting task to give up all of your favourite foods, here is a run-down of some of the tools you’ll need to get it right. Pretty soon, you won’t even miss ice cream (that much)!
The WHY:
The elimination diet is often prescribed to patients who exhibit symptoms of digestive distress (irritable bowel syndrome, inflammatory bowel disease, diarrhea, bloating, flatulence or constipation) and for autoimmune or inflammatory conditions such as arthritis, migraines, asthma, allergic skin conditions or frequent colds and flus, to name a few. The idea is that when there is chronic inflammation in the gut, as a reaction to foods we are sensitive to, the barrier between our gut lining and the rest of the body opens up, allowing particles that shouldn’t be in our blood stream to get in. This can cause widespread inflammation, resulting in symptoms of some of the previously mentioned conditions.
The elimination diet can also be used as a general cleanse or a weight loss tool. Because the diet consists of eating more fruits, vegetables and protein and less processed foods, it often results in the consumption of fewer calories and many patients lose weight on it.
The WHAT:
The Elimination Diet consists of completely removing several foods from the diet for a number of weeks. During this time, usually 3-6 weeks, symptoms of inflammation should resolve as the gut heals. There is a long list of foods that are removed from the traditional elimination diet such as gluten, dairy, eggs, soy, caffeine, sugar, nightshade vegetables (tomatoes, potatoes and eggplants), to name a few. However, some practitioners simply start by removing one or two food-types, often gluten and dairy, in order to eliminate the main perpetrators and to make the task less daunting for the patient.
After the initial period of elimination, foods are reintroduced one at a time, for a few days, to observe if old symptoms return. If the past inflammatory symptoms return with the introduction of a certain group of foods, patients are then advised to stay away from these foods, as they are sensitive to them. Some people, once the gut has healed completely, will eventually be able to return to eating these foods again, but many will not and will have to accept a lifetime free of gluten, for example, in order to prevent their old symptoms from returning. Many foods, when reintroduced, will not cause a negative reaction and both the patient and their naturopathic doctor will deem these foods safe to eat again.
The HOW:
Embarking on a diet where the main staples of many Standard American Diets (bread, cheese, milk, etc.) are banned can be incredibly challenging. For the initial stages of the diet, it is acceptable for patients to replace their old food staples with allergen-free varieties – for example, buying gluten-free bread to make your morning toast. However, in order to promote health and detoxification, the idea is to eventually replace the old habits of eating processed foods with a whole foods diet, ingesting foods that exist in their natural forms with little to no processing. That being said, it is more important to refrain from allergen-containing foods primarily, and explore new ways of eating as you begin to adapt to the diet.
Grocery List:
When given a list of the things you can’t eat, I find it helps to focus on the things that you can, however small it may seem at the beginning. In order to do that, it might help to do an initial grocery shopping trip, removing from your fridge and cupboards the foods that are banned and replacing them with new, healthier, allergen-free varieties.
At the grocery store, stock up on:
Lots of colourful fruits and vegetables of your choice: Start at the periphery of the store and pick up everything that looks good: carrots, celery, kale, spinach, arugula, salad mixes, onions, apples, pears, bananas, avocados, beets, grapes etc. Pick up some frozen vegetables and frozen berries as well, as these come in handy when preparing meals. Read the diet handout carefully for information about what vegetables are allowed on the diet and which ones are to be removed during the initial stages.This is a great opportunity to try new vegetables you’ve never tried before, discovering their health benefits, experiencing their interesting flavours and adding more variety – and nutrients – to your diet.
Meats: Choose your favourite cuts of chicken, lean pork, beef, turkey or whatever else you enjoy eating.
Snack foods: Hummus, gluten free crackers (Mary’s crackers are popular), rice cakes, Lara Bars. Also purchase raw, unsalted almonds, walnuts and other nuts to snack on. Chia seeds are versatile for snacks as well. Purchasing whey isolate protein powder (whey concentrate contains casein, which is a no-no on a dairy-free diet), is another great option for adding to baked goods, smoothies and other gluten-free recipes to increase their protein content.
Condiments: Purchase almond butter, coconut oil and extra virgin olive oil for cooking. Temari sauce is a good substitute for soya sauce (which contains wheat). You can also go nuts on delicious spices and seasonings such as garlic, turmeric, cumin, paprika, oregano, basil, cilantro, sea salt, etc.
Milks: Purchase almond milk – I prefer Almond Breeze original, unsweetened for my morning coffee, baking and cereal, if I have it – or coconut milk (the kind in the can found in the “ethnic” foods section).
Flours: Some gluten-free flours are not the best in terms of how healthy they are for you. White rice flour, tapioca flour and potato flour contain less fibre and nutrients than regular flour so it’s best to stay away from them. At the Bulk Barn you can find grain-free flours like coconut and almond flour, as well as healthier grain flours such as teff flour, quinoa flour and brown rice flour. At my house we buy a variety and mix them together to create a healthy, gluten-free “all-purpose flour” for baking. For more on allergen-free baking, read this post.
Bread: My favourite gluten-free bread can be purchased at Costco in a double-pack and is made by a company called Silver Hills. It is high in fibre and contains omega-3’s making it one of the more substantial, tasteful gluten-free breads available. However, I usually only break it out when I’m desperate for morning toast or really crave a sandwich because, when it comes to gluten-free bread, a lowering of expectations must be in order. These breads must be kept frozen and toasted in order to be enjoyed. Most people on a gluten-free diet simply end up forgoing bread in general. However, I recommend this brand as a good transition as it comes as close as possible to any real bread I used to enjoy.
Pasta: Another Costco brand, TruRoots, makes an ancient grains line of pasta, which contain buckwheat, amaranth, brown rice and quinoa. These make a great substitute when you just want to boil some spaghetti for dinner. Another spaghetti option is making it from spaghetti squash, a great way to increase your vegetable intake and decrease your calorie consumption.
Fortunately there are a number of great gluten-free blogs on the internet and great cookbooks containing easy to make, healthy recipes. Here are some of my favourite websites, but oftentimes I just Google specific ingredients (e.g.: “almond flour pancakes”) or a search term like “gluten-free” or “paleo” to see what recipes come up and then modify accordingly. As you become accustomed to what foods you can and cannot eat, you’ll learn to add and subtract certain ingredients from your favourite recipes, giving them a hypoallergenic twist.

Eating Out:
Many restaurants offer gluten-free varieties of their traditional menus such as GF hamburger buns or rice pasta. I find, however, that most ethic restaurants such as Indian, Ethiopian, Thai, Greek, Chinese or Vietnamese, which use rice instead of wheat-containing foods like bread, are naturally gluten-free. Asking if the recipes contain dairy and other foods that you’re avoiding might be necessary in case you aren’t aware of the exact ingredients of the foods you’re eating. For this reason, I prefer eating at home, where you know exactly what’s going into your food.
Eating at a Dinner Party:
It seems that more people have at least a basic awareness of what “gluten-free” means these days. For some, though, it might help to have a prepared explanation of why you’re choosing to eat this way to be able to educate those who are curious about your dietary restrictions. I find it helps to have results on hand; when you look and feel better, not much is left to debate. I find that those who are hostile to someone who is trying to avoid certain foods are often insecure about their own eating styles and, if you suspect that this is the case, it’s best to change the subject and move on.
As for the menu, remember that at most dinner parties salad and meat are usually served. You can simply forgo bread, asking for a burger without a bun or staying away from the bread basket. And, as for dessert, a friend of mine’s strategy is to always bring along her own. If no one else wants to share it, at least she has her own to indulge in and she finds that most people are gracious when you offer to bring dessert. In addition, trying a great, allergen-free recipe is a nice way to introduce the elimination diet to your family and friends (and promote naturopathic medicine).
The elimination diet can seem like a steep hill to climb at first, but, fortunately, hypoallergenic eating is becoming more commonplace, making it easier to find gluten and dairy-free substitutes to the foods you love. After an initial adjustment period, you probably won’t even miss the old foods and besides, feeling great and pain-free is just so much better than reaching for the bread basket.
That is often the health question… On this blog I have openly admitted to loving coffee. Throughout the course of applying my studies in naturopathic medicine to my own life, I’ve been able to make necessary changes to my diet and have watched the way I eat evolve quite dramatically over the past three years. I was once a vegetarian, who ate a carb-heavy diet, full of pasta, and now I follow a whole foods diet, free of diary, gluten, processed foods and refined sugars. There is one thing I’ve been unable to give up for good, however, and that’s coffee.
I can go time without it and often put myself to the challenge to do so. But, while it’s been over a year since I’ve bitten into a baguette, I just can’t say good-bye to coffee forever. And should I even try? When it comes to coffee, there are few foods that receive more mixed messages with regards to the health benefits or risks. Here are some of the pros and cons to visiting your favourite local beanery.
Dr. Ray Cronise, a former NASA scientist, outlines a food pyramid in his paper to help organize food into nutrient content. I often borrow his pyramid to depict nutritional balance to my patients.
Since we rarely eat pyramids, I often depict this balance for my patients using a plate. I divide the plate into four quarters. One half of the plate is dedicated to colourful vegetables, with at least a full quarter dedicated to greens. The other two quarters of the plate are divided into starches: grains, legumes, tuberous vegetables, and proteins: meat, dairy, eggs, fish, or legumes. Oils and fats can be used to cook with or added to the meal in the form of avocados, nuts and seeds.
