What's Happening?
A study conducted by King's College London has revealed that daily intake of certain prebiotic supplements can enhance cognitive function in individuals over the age of 60. The research involved 36 pairs of twins, with one twin receiving a daily prebiotic mixed
into protein powder, while the other received a placebo. The study found that those who consumed inulin or fructooligosaccharide (FOS) scored higher on cognitive tests after three months. These supplements also led to beneficial changes in the gut microbiome, particularly increasing the presence of Bifidobacterium, which is linked to improved cognitive function.
Why It's Important?
The findings of this study are significant as they suggest a potential non-invasive method to improve brain health in the aging population. With Alzheimer's disease being a major concern, the ability to enhance cognitive function through dietary supplements could offer a promising approach to delay or mitigate cognitive decline. This research supports the growing evidence of the gut-brain connection and highlights the importance of gut health in maintaining cognitive function. The study's implications could lead to broader acceptance and use of prebiotics as a preventive measure against cognitive disorders.
What's Next?
The researchers plan to investigate whether the cognitive benefits observed can be sustained over longer periods and in larger groups. Further studies may explore the potential of these supplements in preventing or slowing the progression of cognitive decline. The study also opens avenues for exploring other dietary interventions that could support brain health, potentially leading to new guidelines for aging populations.
