The gastrointestinal microbiota, a collection of trillions of microorganisms within the intestinal tract, has metabolic, immunologic, and protective functions that contribute to health. Diet and exercise affect the composition and function of the gut microbiome via substrate availability and physiological changes in the gastrointestinal environment. Dietary fiber is a key nutrient that supports gut health and gut microbiota. Alternatively, excess protein intake may have negative effects on gut health, including microbial metabolism of non-digested protein, which results in the production of proteolytic metabolites that may be detrimental to gut health. The fermentation of non-digested protein is even more pronounced in individuals with inadequate dietary fiber intake. Thus, to optimise gut health and support the gut microbiota, both dietary fibre and protein consumption should be considered.
