Daily Fiber Supplements Found to Enhance Senior Brain Function in 12 Weeks

Study reveals potential for gut-brain axis targeting in Alzheimer's prevention.

A new study shows daily fiber supplements improve brain function in individuals over 60 in just 12 weeks, without affecting muscle strength.
The research, conducted by King's College London, found significant changes in the gut microbiome, particularly an increase in beneficial bacteria like Bifidobacterium.
The study used a double-blind, remote design, demonstrating the feasibility of conducting trials in older adults without extensive travel or hospital visits.
The supplements tested were inulin and FOS, cheap, commercially available plant fibers that are safe and easy to take.
Researchers plan to explore whether these cognitive benefits are sustained over longer periods and in larger groups of people.
