‘Gut’ with the program: How your microbiome keeps you healthy

Bacteria often get a bad rap. From ear infections to strep throat, many people associate bacteria with infections, a doctor’s visit and a possible round of antibiotics. But in terms of gut health, the better the bacteria, the better you feel.

The most beneficial bacteria ? The bacterial species that live in your digestive system, or gut microbiome , according to the U.S. National Human Genome Research Institute .

Microbiome refers to a group of microbes that live in your gut to help with digestion, destroy harmful bacteria and help control your immune system. One way to think about your gut microbiome is that it’s the gardener for your entire body. By tending the plants (good bacteria) and getting rid of the weeds (unhealthy bacteria), your gut contributes to your body’s bountiful harvest (other body system functions).

Here’s how a balanced gut microbiome impacts your overall health. Your stomach doesn’t absorb the majority of the nutrients you eat. It’s the small intestine’s job to break down the essential nutrients.

Your gut’s bacteria produce the enzymes that help break down indigestible carbohydrates. When this process doesn’t work as it should, serious health problems, like food intolerances and allergies, can occur. Our microbiome also nourishes the cells in the gut wall.

Healthy and satiated gut cells work in tandem with the immune system cells to help ward off colds, allergies, joint pain and acne, as well as working to fight potentially more serious.
