What is the "gut"?

The gut, aka the gastrointestinal system, gastrointestinal tract, digestive system, or digestive tract all refer to the same group of organs that work together to keep you healthy, according to NYU Langone Health. Organs that are considered to be part of the digestive system include the mouth, stomach esophagus, pancreas, liver, gallbladder, small intestine, colon, and the rectum. 

Maintaining the well-being of these organs is absolutely vital to sustaining good health — they absorb nutrients and water, aid in delivering messages to the brain, and fight off infections. The gut is only able to perform these actions, however, by maintaining a healthy biome for its bacteria. According to Healthline, the human body contains 40 trillion bacteria, and most of it is located in the gut.

How do I know if my gut is healthy?

“With a healthy functioning digestive system, you’re not reactive to foods or external inputs like stress or environmental factors,” Rosia Parrish ND, a Colorado-based naturopathic doctor told Everyday Health. “You also have less susceptibility to conditions such as skin disorders, autoimmune conditions, inflammatory responses, and other health concerns.

How to maintain a healthy gut:

If your gut is clearly suffering, consult a doctor — a naturopath, gastroenterologist, or a nutritionist. But once any problems are properly addressed, there are many ways to maintain a healthy gut. Medical News Today recommends upping your intake of probiotics, which essentially gives your gut's "good bacteria" a "boost." Probiotic supplements are available over-the-counter, and fermented foods, such as kefir, kimchi, kombucha, and natto are natural probiotics sources.

Prebiotic fibers are also known to help probiotics sustain environmental change — you can get these naturally from asparagus, bananas, garlic, chicory, and whole grains, or you can take an OTC prebiotic supplement. Eating less sugars, properly managing stress, getting regular sleep and exercise, avoiding disinfectant cleaning products, avoiding smoking, and abiding by a plant-based diet are also proven to help improve gut health.
