London: Gut microbes have a vital bearing on our health by producing vitamins, priming our immune system and developing resistance to pathogens.For example, studies have shown that the insulin resistance of type-2 diabetics is linked to intestinal bug composition and can be beneficially altered by replacing it with that of healthy donors.The genes of our gut microbes, also known as the microbiome, act as a personalised organ that can be modified by diet, lifestyle and antibiotics. This organ is fed partly by us and partly by our diets.Willem M.de Vos, professor in microbiology at the Helsinki University (Finland), and colleagues have classified the human microbiome into three enterotypes: clusters of microbiomes with similar compositions and nutrient-processing preferences, according to a Helsinki statement.
