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.
