Prebiotic fiber may enhance memory in older adults

A study from King’s College London suggests that a daily prebiotic fiber supplement may enhance memory and gut health in older adults. Researchers tested 36 pairs of twins over 60, finding improvements in cognitive scores after 12 weeks. In the double-blind study, one twin received a prebiotic supplement while the other received a placebo. Those taking the prebiotics showed better results on visual memory tests, which can indicate early signs of Alzheimer’s disease. The study also noted changes in gut bacteria, with an increase in beneficial Bifidobacterium among those consuming the supplements. Researchers see potential for these findings to improve brain health in the aging population.
