Cheap Daily Fibers Linked to Memory Gains in Older Adults, Twin Study Says
In a 12-week, double-blind twin study from King's College London, older adults consuming a daily prebiotic blend (inulin or FOS) with protein powder showed improved memory test scores and subtle gut microbiome changes (including more Bifidobacterium) versus their co-twins taking a placebo, with no significant physical benefits observed. The findings support the gut-brain axis as a potential target for aging-related cognitive decline, though larger, longer trials are needed.
