As the global population ages, age-related conditions like cognitive decline and muscle loss are on the rise. A recent study published in Nature Communications delved into the impact of plant fiber supplements on the microbiota to understand their effects on muscle health and brain function. The study, involving 72 individuals from 36 twin pairs, uncovered that a daily fiber supplement can boost brain function in individuals over 60 within 12 weeks.
While the addition of prebiotic supplements inulin and fructo-oligosaccharides showed no influence on muscle strength, it significantly transformed the participants' gut microbiome composition, notably increasing beneficial bacteria like Bifidobacterium. This study not only reveals shifts in gut microbiome composition but also underscores the practicality of conducting remote trials with older adults, addressing issues like digital literacy.…
