TL;DR: The need to consider the microbiome when evaluating human development, nutritional needs, physiological variations and the impact of westernization is underscored, as distinctive features of the functional maturation of the gut microbiome are evident in early infancy as well as adulthood.
Journal ArticleDOI

TL;DR: Alternative enterotype states are associated with long-term diet, particularly protein and animal fat (Bacteroides) versus carbohydrates (Prevotella) and other enterotypes distinguished primarily by levels of Bacteroide and Prevotella.
