In more recent years, studies have been emerging that focus on the possible connection between gut health and mental health disorders, including anxiety and depression. The microbiome makes up all microorganisms in the human body. The microbiota encompasses all the microorganisms in a particular location, such as the GI tract. These together are developed while in the womb. During this time, early nutrition can play a role in shaping the developing gut microbiota. This helps with the development of various healthy bacteria.

The Science Behind Gut Health and Mental Health
As solid foods are introduced to infants, the microbiome is exposed to many different energy substrates, creating and developing our metabolism along with new variations of bacteria that make up the gut. It is difficult to determine what a normal microbiome consists of given the environmental, seasonal, and health status of an individual. Although, what we eat can determine what type of bacteria are predominantly present. This can also be directly linked to inflammation of the GI tract, placing stress on the microbiome. This can result in the release of cytokines and neurotransmitters. Elevated blood levels of these pro-inflammatory markers increase the permeability of the blood-brain barrier. Their release influences brain function, leading to anxiety and depression.
Pro-inflammatory cytokines are also important stimulators of the hypothalamic-pituitary-adrenal axis (HPA). The hypothalamus releases various hormones, one in which stimulates the adrenal release of cortisol, a known stress hormone. Cortisol stimulates a pro-inflammatory response, leading to a dysregulation of the HPA axis, resulting in symptoms of depression and anxiety.
When the human microbiome is challenged with dietary changes, coupled by stress, or maybe a course of antibiotics, the physiology of the normal microbiome changes. When there is a loss of beneficial bacteria, this can trigger a pro-inflammatory response and weaken the intestine. This can lead to increased intestinal permeability and allow bacteria to leak through, leading to detrimental effects on our bodies, which can be demonstrated in diseases such as irritable bowel syndrome (IBS), and mental health disorders such as anxiety and depression.
Probiotics, living microorganisms of yeast and bacteria, have been utilized as supplements for aiding in reducing symptoms of anxiety and depression. Primarily, they have been studied in the suppression of cytokines, noting improved intestinal barrier integrity. This promotes a decrease in inflammatory response. As a result, adding a probiotic to your daily regimen could help reduce pro-inflammatory hormones, especially in individuals suffering from chronic inflammation.
Although, there is no FDA regulation pertaining specifically to probiotics, and ultimately, no dosage recommendations. Until more research behind the use of probiotics as therapy for anxiety and depressive disorders is available, probiotics cannot be considered a reliable treatment method as compared to psychiatric medications.
When it comes to diet, various components in food can help reduce inflammation. Consider foods that are high in fiber, omega-3s found in fish, oils, and leafy greens, polyphenols (plant chemicals) found in fruits such as berries, and unsaturated fats found in almonds and flaxseeds. All of these foods can be incorporated into your daily diet to help reduce inflammation and promote a healthy gut and microbiota!
- Yogurt: containing live bacteria cultures, yogurt can help support a healthy gut by keeping the microbiome healthy. The probiotics in yogurt can help reduce inflammation and symptoms of bloating, gas, constipation or diarrhea. Many yogurt varieties contain added sugar, so look for plain options and add your own flavoring with fruit, nuts, and seeds to avoid excess sugar intake.
- Fermented foods like Kombucha, kimchi, sauerkraut, kefir and miso are rich in probiotics. The good bacteria grow during the fermentation process. Add fermented foods to your diet for a healthy dose of probiotics.
- Dark Green Leafy Vegetables: Packed full of vitamins like A, K and magnesium, dark green leafy vegetables, such as spinach, kale, bok choy, mustard greens, and collards, are crucial for brain function and gut health. Swiss chard is a great example of a food that is loaded with fiber, feeding the healthy bacteria in your gut, preventing inflammation.
- Omega-3s: Omega-3 fatty acids also support brain health. Fatty fish such as salmon and tuna, are great sources of omega-3 fatty acids. Foods containing fatty acids can help reduce inflammation, and support healthy digestion. This can help you feel less bloated and sluggish.
- Healthy Grains: Whole grain foods, such as oatmeal and bulgar wheat, are high in fiber, which plays an important role in stabilizing blood sugar levels. This helps restore a potential imbalance to the gut that can happen when blood sugar levels are challenged. Most whole grain products contain beneficial prebiotics that help increase healthy bacteria in the gut microbiome.
- Berries: Berries are rich in antioxidants, which can help keep your gut healthy by reducing inflammation. They are also a great source of prebiotics, which promotes healthy gut motility. One of the highest vitamin C foods, which can improve the gut barrier and enhance nutrient absorption.

Anti-Inflammatory Diet, What it is, What it Does and Including a Meal Plan by Licensed Nutrition Counselor, Liz Mckinney, CNS, LDN.
Every standard anatomy course covers a section on inflammation, health circles and modern medicine studies how this physiological process effects our bodies. Modern science has uncovered much evidence related to how our dietary consumption fuels our internal inflammation. To understand inflammation, let’s talk what about what inflammation really is. Inflammation is a normal part of our body’s healing process. Think of the redness, pain and swelling that comes along with an acute injury. These are bio-markers that our white blood cells are migrating to the origin of a wound, when the white blood cells arrive they will unfold to facilitate the healing process. This mechanism is a normal and necessary indication that our immune response is hard at work. But what happens when our immune systems are working over time in a way we can’t see? This is a part of what is termed ‘chronic inflammation’, and our diet definitely plays a large role in both calming it down or conversely, throwing fuel on the flames.
Chronic inflammation is a contributing factor to many common diseases in the U.S today. Obesity, heart disease, and Type 2 Diabetes are some common diseases to which inflammation contributes to the onset and progression (Lopez-Condelez 2017). Additionally, according to a 2018 study Dr. Billmore et, al, which was published in Nature, there is also evidence that inflammation may contribute to certain forms of depression as well as aiding in the development and progression of this mental health disease, inflammation is also being study as a contributing factor in the development of other mood disorders. Of course diet alone can not provide total therapy for depression or disease but it is an important pathway to providing our best course to become well.
The fact is when our immune system becomes chronically activated, low-grade, systemic inflammation occurs. Even if you aren’t suffering from an overt disease, things like stress, leaky gut, food sensitivities and even an imbalance in our gut micro-biome all are capable of pushing our bodies into an inflammatory state. The consequences of chronic inflammation are serious. Increased risk of neuro-degenerative and cardiovascular disease, trouble losing weight, digestive problems, hormonal imbalances, and cellular damage may all occur as a result.
Our food choices can either promote or calm inflammation. Many of the diseases and problems listed above may be prevented or mitigated with an anti-inflammatory diet. The top foods that commonly contribute to chronic inflammation in the standard American diet are:
- Refined grains (bread, crackers, cookies, cakes, snack foods)
- Dairy (all cow dairy products including milk, ice cream, and yogurt
- Sugar (table sugar, high fructose corn syrup, sugar alcohols or artificial sweeteners)
- Vegetable oils (Canola, Corn, Safflower, Sunflower and Rapeseed oils)
- Trans fat (Margarine, peanut butter, mayonnaise, packaged snacks)
- Conventional/commercially raised meat
- Alcohol (More than 1 drink per day for women and 2 for men)
- Food additives (MSG, artificial flavors and food dyes)
On the flip side, nourishing foods can also accelerate healing in the body and prevent the inflammatory cascade from becoming chronic. For whole body health and wellness, add these anti-inflammatory foods into your daily diet:
- Fatty fish (Halibut, salmon, sardines, trout)
- Coconut oil
- Olive oil
- Vegetables (Any and all kinds!)
- Chia seeds
- Flax seeds
- Grass-fed animal meats
We know that one of the barriers to incorporating dietary changes is that we simply don’t know where to begin. As an added bonus, we will share an example one-day meal plan, made by a certified and licensed Nutrition Counselor, Liz Mckinney, by using this plan, you can jump start your anti-inflammatory diet today!
- 2 scrambled eggs with sautéed spinach, mushrooms and garlic
- ½ avocado
- 2 cups mixed greens with 4 oz. salmon or chicken and walnuts with a turmeric ginger dressing (Juice from 2 large organic lemons, approximately 1/4 cup of fresh juice, 1″ fresh ginger, skin removed, 1 garlic clove, 2 teaspoon ground turmeric, 3 tablespoons extra virgin olive oil, 1 tablespoon apple cider vinegar, 1/4 teaspoon black pepper, Salt to taste – Blend in food processor)
- Sautéed lemon pepper shrimp over zucchini “noodles” sautéed in olive oil with salt and pepper
- 70% or greater dark chocolate, almonds/walnuts, rice cake with mashed avocado, hard boiled egg with spicy mustard, cut up veggies with hummus or another home made veggie dip
Additionally, by working with a licensed nutritionist or dietitian to identify food sensitivities, heal leaky gut, balance your gut micro-biome, eradicating bacterial overgrowth, and implementing a stress reduction plan into your daily life, your wellness, emotional, and physical health can be optimized. As always, wellness routines that include yoga, meditation, mindfulness, progressive muscle relaxation, spending time in nature, or deep breathing are all proven techniques to increase resilience to stress.
