Daily fibre supplements shown to improve brain function in over 60s
A study from King’s College London presents promising findings that daily fibre supplements could improve cognitive functions and memory in adults over 60, offering a potential dietary approach to healthier aging.
A study conducted by King’s College London has highlighted the potential cognitive benefits of daily fibre supplements for adults over 60, suggesting improvements in brain function and memory, particularly in areas related to early Alzheimer’s disease. The research, led by Dr. Mary Ni Lochlainn, involved the administration of prebiotic supplements, specifically inulin and Fructo-oligosaccharides (FOS), to 72 participants aged over 60 across 12 weeks. These participants were divided into two groups: one received a placebo, while the other was given the actual fibre supplement.
The findings, published in Nature Communications, revealed that those who took the fibre supplement showed significant improvements in their gut microbiome, with an increase in beneficial bacteria such as Bifidobacterium, and performed better in cognitive tests measuring aspects like reaction time, processing speed, and memory. These tests are crucial indicators of cognitive health, suggesting the supplements could enhance day-to-day brain function and contribute to healthier ageing.
Despite no observed change in muscle strength, the results, according to Dr. Ni Lochlainn, are promising for brain health and memory enhancement in the ageing population. The research underscores the potential of simple dietary additions in improving cognitive health and the importance of the gut-brain axis in this process.
The researchers have expressed a need for further investigation to determine whether these cognitive benefits are sustainable over extended periods and if similar improvements can be observed in larger population groups. The study offers hope for a cost-effective and accessible means to improve cognitive health among older adults, leveraging over-the-counter plant fibres.
