Gut Power Boosts Memory Over 60

A recent study involving twins over 60 has uncovered a compelling link between gut health and cognitive function. Participants taking daily prebiotic supplements, such as inulin and fructooligosaccharide (FOS), alongside protein powder, demonstrated notable improvements in memory and learning tests after just 12 weeks. These findings, published in 2024, highlight the potential of affordable, accessible supplements to support brain health.

The research, conducted at King's College London, observed significant changes in the gut microbiome, with an increase in beneficial Bifidobacterium bacteria in those consuming the supplements. This aligns with prior rodent studies suggesting that a healthier gut microbiome can positively influence the gut-brain axis. The study's lead researchers expressed excitement about these early results, seeing them as a promising step towards new strategies for combating age-related cognitive decline.

While the study focused on cognitive benefits, it did not find significant improvements in physical aspects like muscle loss. However, the accessibility and low cost of these prebiotic supplements make them an attractive option for supporting the aging population. Future research aims to confirm these effects over longer periods and in larger, more diverse groups, further exploring the gut's role as the body's 'second brain'.
