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.

#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.

The Gluten Free Diet: Bad or Good?

/in , , , /by

Diet is known to affect the gut microbiome, the ecosystem of helpful bacteria that lives in our stomach and intestinal tract. Certain foods can promote diversity and multitude of “good” bacteria, improving energy metabolism, boosting immune response, reducing inflammation, and affecting many other areas of physical and mental health. 

Gluten, a wheat protein naturally occurring in rye, farro, barley, oats and other grains, is found in hundreds of popular foods, from pasta, to beer, to salad dressing, to candies. For those with a gluten intolerance, gluten can harm the gut microbiome, increasing inflammation and damaging the intestinal tract. Others report having a “gluten-sensitivity,” which is accompanied by stomach pain, diarrhea, bloating, and cramping. 

The gluten-free diet has gained enormous traction in recent years, not just as a treatment for chronic gluten-intolerances such as celiac disease or wheat allergies, but as a way to lose weight and be healthier. In a survey conducted by the Consumer Reports National Research Center, 63% of Americans thought that following a gluten-free diet would improve physical or mental health and 25% thought that gluten-free foods were higher in vitamins and minerals. For many, a “gluten-free” label has become synonymous with healthfulness. 

Unfortunately, food retailers have weaponized this phenomenon by using the nutritional authority of the “gluten-free” label to sell products that aren’t necessarily healthier, at higher prices. This infographic by Consumer Reports compares products with and without gluten. Gluten-free products often have more calories, sugar, sodium, and fat, as well as less beneficial nutrients like fiber and protein. Wheat flour, which contains gluten, is often replaced with rice flour and other less-nutritional alternatives. 

While the widespread accessibility of gluten-free products has been life-changing for those with gluten-sensitivities, the influx of processed, less-nutritional gluten-free foods has arguably been harmful for many. Like other food trends, the gluten-free diet should be approached with mindfulness and skepticism. 

Is The Gluten-Free Diet Right For You?

For those suffering from celiac disease, a gluten sensitivity, gluten ataxia, a wheat allergy, IBD, or another condition tied to gluten-intolerance, a gluten-free diet is crucial for managing symptoms. If you suspect that you may be suffering from a gluten-related medical condition, consult a doctor for testing. Diagnosing yourself, or choosing to eat totally gluten-free for weight loss without consulting a nutritionist is not recommended. Receiving adequate nutrients on a gluten-free diet can be difficult for many. 

For those of us who don’t suffer from a gluten-related medical condition, gluten is recommended in moderation. Ultimately, avoiding processed foods is far more effective than cutting out gluten altogether. As discussed, many gluten-free products are highly-processed and can be harder to digest, less nutritional, and harmful for the gut microbiome. Consuming more naturally-occurring gluten-free foods, such as fruits, vegetables, legumes, certain whole grains, fish, dairy, and meat, is the best way to cut out gluten, get plenty of vitamins and minerals, and avoid sneaky branding. 

As with any medical condition, it is always best to seek assistance from a qualified medical professional if you are experiencing symptoms that are causing you difficulty.

Popular Food Emulsifier Found To Harm Gut Microbiome

/in , /by

While you probably haven’t heard of carboxymethylcellulose (CMC), you’ve definitely eaten it. As the most widely-used cellulose-based emulsifier in the world, CMC is found in almost every type of processed food. And, unfortunately, new research has connected CMC to a range of negative gastrointestinal symptoms. 

What is CMC?

CMC is a stabilizing and thickening agent used in food and nonfood products, including ice cream, milk, fruit juice, toothpaste, detergents, water-based paints, chewing gum, dye, protein drinks, laxatives, and many more processed items. Its use is extensive and fair-reaching, from adding bulk to ketchup to acting as a viscosity modifier in the oil industry.

CMC’s makeup is what has made it so versatile and popular. Considered nontoxic and hypoallergenic, the highly viscous (thickening) substance is derived from cellulose, an organic compound. It easily absorbs/retains water and is clear, tasteless, and colorless. It is known as an emulsifier, a ubiquitous agent used to improve the experience and longevity of food. While it has no nutritional value and cannot be digested by humans, it has long been considered safe to consume. 

In fact, CMC has been used in the food industry since the 1960s. It is generally used in the production of baked goods, since its calorie-free and gluten-free. It is also used as a “texture enhancer,” creating a thicker, creamier “taste experience” in many sauces, jams, and even sausages. On labels, CMC may also go by the name of sodium carboxymethyl cellulose or sodium CMC. 

The Truth About CMC 

Clinical research published in Gastroenterology Journal this past November 2021 found important new insights into the impact of CMC on gut health. In this randomized controlled-feeding study, a group of healthy volunteers were either subjected to a CMC-free diet or a diet with CMCs. Research found that those who consumed CMCs experienced stomach pain, loss of gut bacteria diversity, loss of short-chain fatty acids and amino acids, and symptoms associated with IBD and gut inflammation. 

This isn’t the first study to find fault in CMC, or emulsifying agents in general. In 2015, a study published in Nature found a direct connection between dietary emulsifiers and low-grade inflammation, changes in gut microbiota, obesity/metabolic syndrome, and colitis in mice. 

The findings of both studies can suggest that the widespread use of emulsifying agents like CMC may directly correlate to the rise in IBD (irritable bowel disease), colon cancer, and chronic inflammatory conditions in human populations. By altering the composition of the gut microbiome and number of metabolites present, these agents cause chronic, lasting detriment to gut function and health. 

Beyond suggesting a need to study the effects of CMC and other emulsifiers more extensively, this study “provides a general blueprint to carefully test individual food additives in humans in a well-controlled manner,” according to co-senior author Dr. James Lewis of the University of Pennsylvania. Indeed, this study has highlighted the necessity for large-scale research into the assembly of processed foods, especially components long-believed to be safe and nontoxic, like CMC.

Why You Need To Add More Fiber To Your Diet

/in , /by

These days, the importance of consuming dietary fiber is fairly common knowledge. Most of us make an effort to add fiber to our diets, whether it be through a fiber-rich cereal or daily multi-vitamin. 

But, even if you’re taking strides to include fiber in your diet, you’re likely not getting enough! On average, Americans eat about 15 grams of fiber a day. That number should be between 25 and 35 grams, or more. And not just from supplements or vitamins, but from whole foods.

Fortunately, there are many ways to incorporate more fiber into your diet. Keep reading to learn about what fiber is, why it matters, and some high-fiber foods to add to your grocery list. 

What Is Fiber?

Dietary Fiber is a carbohydrate found in plants such as fruits, vegetables, nuts, seeds, legumes, and whole grains. Unlike other nutrients such as proteins and fats, fiber cannot be digested by the body. It simply passes through the stomach, small intestine, and colon. 

There are two types of dietary fiber: soluble and insoluble. They are important for different reasons, and many foods contain both types. Soluble fibers can be dissolved in water, which helps regulate blood sugar and cholesterol levels. Insoluble fibers cannot be dissolved in water, which adds necessary bulk to stool, promoting regularity of the digestive tract. 

Why Is Fiber Important?

Beyond fiber’s ability to regulate blood sugar levels, balance cholesterol, and promote regularity, adequate fiber consumption has been linked to a reduction in the risk of heart disease, diabetes, certain types of cancer, and many gastrointestinal conditions such as colorectal ulcers, hiatal hernias, gastroesophageal reflux disease, diverticular disease, and hemorrhoids. Plus, by reducing the risk of constipation, fiber helps improve gut health. High fiber foods are also generally healthier and more filling than processed, low-fiber foods.

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.
