When comparing the microbiomes of exercising individuals (including athletes) with those of sedentary individuals, scientists have found: More bacterial diversity and/or richness, generally regarded as beneficial to health More short-chain fatty acid (SCFA) metabolic pathways, important for intestinal integrity and other aspects of health Increased metabolic pathways of amino acids (including branched-chain amino acid,…
