The balance of microbial populations making up the gut microbiome is different from individual to individual, and changes with age in detrimental ways. Pro-inflammatory microbes, as well as those that create otherwise harmful metabolites, expand in number at the expense of microbial populations that produce beneficial metabolites. Evidence strongly suggests that both variations between individuals and age-related changes in the gut microbiome can contribute to age-related disease and mortality. Here, for example, a study in rabbits shows that specific differences in the gut microbiome correlate well with obser…
