What Is a Gut Health Nutritionist?

First things first: what is "gut health?" Gut health refers specifically to the balance of bacteria in the large intestine. For a gut to be considered healthy, the large intestine should contain a balance of "good" and "bad" bacteria, also known as gut flora. Both good and bad bacteria serve different purposes. While the good bacteria feed on fiber, the harmful bacteria consume simple sugars, which produce compounds like vitamin K and biotin.
