A recent study published in Nature Communications unveiled the remarkable potential of a daily fiber supplement in enhancing brain function among individuals aged 60 and above, all within a mere 12-week timeframe.
Researchers at TwinsUK, the UKs largest adult twin registry, investigated how targeting the microbiota with plant fiber supplements inulin and FOS could improve muscle health and brain function as age-related conditions like cognitive decline and muscle loss increase globally.
The study involved 72 pairs of twins over 60, divided into groups receiving either a placebo or the fiber supplement over 12 weeks.
Surprisingly, no significant differences in muscle strength were observed between the groups. However, the fiber supplement induced notable alterations in gut microbiome composition, particularly an increase in beneficial bacteria such as Bifidobacterium.
Remarkably, participants receiving the fiber supplement demonstrated improved performance in brain function tests, including the Paired Associates Learning test, a recognized early indicator for Alzheimer’s disease. Regrettably, prebiotic supplements inulin and FOS did not yield any significant impact on muscle strength.
The study’s remote design showcased the feasibility of conducting trials with older adults, eliminating the necessity for extensive travel or hospital visits. This approach holds promise for widespread implementation across various global settings. However, challenges like digital literacy and access to necessary technology were recognized and will be addressed in future endeavors to enhance the well-being of aging populations worldwide.
