Enterotype
Enterotypes are classifications of the human gut microbiome based on the predominant bacterial groups and their metabolic functions. There are three main enterotypes: Bacteroides-dominant (Type 1), Prevotella-dominant (Type 2), and Ruminococcus-dominant (Type 3). Each type has distinct characteristics in how nutrients such as fats, carbohydrates, and proteins are metabolised. For instance, Prevotella (Type 2) is more efficient at carbohydrate utilisation, particularly in fibre-rich diets, but less capable of synthesising certain vitamins. Your enterotype may influence nutrient absorption, gut health, and how your body responds to different types of diets.
Description
An enterotype is a classification of the gut microbiome based on the predominant bacterial groups present in your intestines.
There are three main enterotypes: Type 1 (Bacteroides), Type 2 (Prevotella), and Type 3 (Ruminococcus).
Your enterotype affects how your body metabolises nutrients and absorbs vitamins. It may also influence your response to certain diets.
While your enterotype is relatively stable, dietary changes—such as increasing fibre intake—can influence the proportions of different bacteria over time.
There is no “best” enterotype; each has strengths and weaknesses. For example, Prevotella is effective at processing carbohydrates, whereas Bacteroides excel at synthesising certain vitamins.
