Each of us has a community of microbes that lives in our digestive system. Scientists call this community our gut microbiome. It plays many important roles in our bodies, like helping to digest food, regulating our immune system, preventing diseases, and even affecting our appetites and our emotions.
Many things, like what we eat and drink, who we interact with, and the medicines that we take, influence the kinds of microbes that live in our gut. A diverse microbiome is good for our health!
