#GutHealth: Discerning Trend From Reality

/in , /by

“Gut health” seems to be a social media buzzword these days, with TikTok and Instagram influencers pushing products, juices, and bizarre diets to “heal” the gut, i.e., reduce bloating, improve digestion, and act as a sort of “cure all” for many common gastrointestinal symptoms and conditions, such as IBS and IBD. Aloe vera juice, bone broth, apple cider vinegar, probiotic-enriched muffin mixes–With so many emerging and unverified natural and unnatural remedies floating around the internet, it can be overwhelming to discern fact from fiction. 

At the same time, there’s so much new and exciting research around the role of the gut microbiome in overall physical and mental health. Research has found that boosting the diversity of gut microbiota (the vast array of “good” bacteria in your digestive system) can have positive effects on the immune system, improve mental health conditions like depression, improve sleep and heart health, and even reduce the rate of certain types of cancer. 

That being said, these recent, ungrounded social media trends are nothing but dangerous. 

In a recent New York Times article, University of London senior lecturer Stephanie Alice Baker defined these fads as the latest manifestation of the idea of “self-optimization,” an insidious mechanism to promote diet culture and “ideal” body types through unlikely sources. By labeling weight loss as “gut healing,” influencers are able to promote extreme, unhealthy diets. What’s more, these influencers often have no medical authority and may only be promoting a product because they’re being paid to do so. 

The truth of the matter is: there’s no quick fix, even if it seems to work for someone on #guttok. Many people suffer from gastrointestinal conditions that are best treated by consulting a medical professional. However, there are some research-driven dietary changes you can make to heal your gut over time. Let’s take a look at 6 gastroenterologist-backed methods for diversifying and improving the gut microbiome.

6 Things You Can Do For Your Gut Health

Eat fermented foods.

A clinical trial conducted by researchers at the Stanford School of Medicine found that a diet high in fermented foods, such as kimchi, kefir, and cottage cheese, continually increased microbiota diversity and decreased inflammatory markers over a period of 17 weeks. Fermented foods are rich in good bacteria; read our blog about other types of fermented food and fermentation here. 

Eat more fiber.

The same Stanford trial also examined the role of fiber in diet and found that it increased microbiome function, especially coupled with the consumption of fermented foods. Consuming soluble and insoluble fiber also promotes regularity and digestive function. Learn more about high-fiber foods and the role of fiber on our blog here. 

Reduce consumption of processed foods.

Research has found that regular consumption of processed and ultra-processed foods (like sugary soda, chips, artificial cheese, fried chicken, fast food) reduces gut diversity while increasing symptoms of gut disorders like IBS, the risk of depression, inflammation, and mortality. Unfortunately, many readily-accessible foods with a long-shelf life are highly-processed, even ones that appear “healthy,” so taking time to research nutritional information is key.

Reduce consumption of spicy foods. 

Spicy food isn’t “dangerous,” but consuming it often can irritate the stomach and increase symptoms of certain gut disorders, like IBS, IBD, and acid reflux. 

Don’t smoke.

Smoking and the toxic chemicals in cigarette smokes harms every part of the digestive system; from increasing the risk of heartburn and peptic ulcers to harming intestinal microflora, increasing inflammation, and increasing oxidative stress. 

Take probiotics.

Probiotic supplements and probiotic-rich foods contain life bacteria that contribute to improving gut microbiome diversity. Taking probiotics may be beneficial to your health, but it’s recommended that you consult a doctor first.

6 Fermented Foods For Better Gut Health

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.
