Unlocking The Gut-Brain Connection | Mental Health Awareness Month 2022

/in , /by

May is #MentalHealthAwarenessMonth, a time to amplify the stories of the millions of Americans experiencing mental health conditions as well as promote valuable resources and information concerning mental health statistics and treatment options. Using the hashtag #TogetherForMH, you can share your story or explore other’s across social media platforms. 

During the pandemic, global prevalence of anxiety and depression has increased by at least 25%, according to the World Health Organization. Nearly 56% of all young adults report symptoms of anxiety and depression. What’s more, negative impacts of pandemic stressors have leached into daily life as well: 36% of adults report difficulty sleeping, 32% report issues with eating, 12% report increases in alcohol consumption and substance abuse, and 12% report worsening of pre-existing chronic conditions.  

In the midst of this unprecedented mental health crisis, finding treatment options that are beneficial and sustainable is of the utmost importance. Of course, seeking help can be difficult. Small steps, such as discussing your symptoms with your doctor, a psychiatrist, or even beginning with a trusted relative or friend, is essential. The National Institute of Mental Health has compiled these valuable resources, such as the National Suicide Prevention Lifeline, the Mental Health Information Glossary, and a Tips for Talking to Your Mental Health Provider Factsheet. 

What is the Gut-Brain Connection?

As gastroenterologists, we treat a variety of digestive conditions, such as Inflammatory Bowel Disease (IBD), Colon and Colorectal Cancer, Heartburn, Acid Reflux, and GERD, Constipation, and much more. 

These digestive conditions may sound completely removed from mental health disorders such as depression and anxiety, but they are actually explicitly linked. In recent years, we’ve discovered that there’s a “second brain” in the gut, often referred to as the enteric nervous system (ENS), which directly responds to physicochemical stimuli, produces serotonin and other chemicals that affect how the brain works, and even regulates immune response. This leads to the “gut-brain connection” (GBC), which is the back-and-forth relationship between gut health and brain health. Many functional bowel conditions, such as irritable bowel syndrome and functional dyspepsia, and their symptoms, such as bloating, constipation, diarrhea, occur more frequently in people who experience anxiety, depression, and emotional shifts. Essentially, we’ve found that addressing mental health conditions and keeping stress under control can result in relief from certain digestive conditions; while, in turn, treating your digestive conditions and gut health can help improve your mental health.

New research, published in Molecular Psychiatry this month has found links between certain immune abnormalities in the brain and the gut in people with idiopathic autism. Another study found the impacts of gut microbiome diversity and intestinal flora on your food cravings, and another found connections between certain microbial composition and whether or not you’re a “morning person” or “night owl.” Certainly, we are at the forefront of understanding the numerous impacts of the gut-brain connection.

How can you begin to address your gut health?

We’ve written a lot about this! Beyond seeking diagnosis and treatment for specific medical conditions, you can improve the diversity of your gut microbiome through eating specific foods, taking probiotics, exercising, getting more sleep, and finding ways to manage stress.

6 Fermented Foods For Better Gut Health

/in , /by

Did you know that eating fermented foods can enhance the diversity of the gut microbiome, which reduces inflammation and improves immune response?

If you did not know this, it’s okay. New research is only beginning to unlock the exciting connections between diet, gut microbiome, and body response. A research paper published by Stanford Medicine this July was one of the first formal efforts to delve into the powerful effects of fermented foods on gut health, in particular.

So What Exactly Is Fermentation?

Humans have been fermenting foods for thousands of years. Fermentation is a metabolic process that utilizes live microbes such as bacteria or yeast to create a chemical reaction. In the absence of oxygen, these microorganisms will break down carbohydrates such as sugars and starches into different compounds altogether. This is how simple yeast can turn barley malt into carbonated, alcoholic beer, or how grapes become wine. Fermentation is a natural, nutritious preservation process. You can easily ferment foods yourself, find them on many restaurant menus, or purchase them at a local grocery store!

Why Do Fermented Foods Help The Gut?

Millions of microbes live in your gut, intestines and colon. Known as the gut microbiota, this system of bacteria helps digest food as well as plays a role in your overall health, immune response, metabolism and even mental health. While each person’s unique gut composition is influenced by genetic makeup, your lifestyle can also impact the quality of your gut microbiome. Factors such as your daily levels of exercise and diet can greatly impact the diversity and functionality of gut microbiota.

The live microorganisms found in fermented foods are a source of probiotics, which have innumerable health benefits. These natural probiotics aid the immune system, and in doing so, boost the body’s response to pathogens. Plus, the enzymes and lactic acid created in the fermentation process helps better absorb nutrients such as Vitamin B and C. The full extent of the benefits of fermented foods are only beginning to be realized.

6 Fermented Foods For Better Gut Health

1. Plain Yogurt – Plain yogurt is low calorie, low sugar, and teaming with beneficial probiotics. Add fresh fruit, oatmeal, or granola to make the perfect gut-boosting breakfast.

2. Kombucha – Kombucha is a popular fermented tea beverage. It is carbonated, with a bitter, fruity taste. A single bottle can have as little as 50 calories and millions of good bacteria. Keep in mind that there are many different brands on the market including options without added sugar.

3. Tempeh – Tempeh is made from fermented soybeans, pressed together. Similar to tofu, it is a great meat substitute to be cooked, fried, or baked. It is also a source of antioxidants, probiotics, and is high in protein.

4. Kefir – Kefir is a tangy, yogurt-like beverage made of fermented kefir grains. It is proven to reduce inflammation, strengthen bones, and even reduce symptoms of lactose-intolerance in some people.

5. Kimchi – Kimchi is a Korean dish made of fermented cabbage or similar vegetables like radishes. It can be eaten alone or used as a topping on sandwiches, salads, pasta, etc. You can find it in most grocery stores. Studies have found that it may improve insulin resistance and lower cholesterol.

6. Sauerkraut – Another form of fermented cabbage, sauerkraut is plentiful in fiber, Vitamin C, and antioxidants. It’s also low calorie, and can be put on/in just about anything.

Within recent years, the gastrointestinal microbiome has become an increasingly popular area of scientific study due to its close link to human health and wellbeing. Not only does a person’s gut microbiome help with the digestion of food, but it also plays an important role in supporting the body’s immune system. Future research will no doubt provide additional insight about ways we can improve and support our body’s gut health.
