Researchers here report that a small trial in humans showed that modulation of the aged gut microbiome via dietary supplementation with a prebiotic produced modest benefits to cognitive function. It is interesting that a prebiotic strategy, generally a weak form of intervention characterized by short duration of effect and small effect size, managed this outcome. There was no improvement in physical performance in the study group, only cognitive function. One might contrast this with what is known of the effects of fecal microbiota transplant from a young individual or flagellin immunization on the gut microbiome, meaning much larger and ess…
