A recent study conducted by researchers at King’s College London has shown that taking daily protein and prebiotic supplements can help improve memory test scores in individuals over the age of 60. This is the first study of its kind to explore the effects of these supplements on brain function in older people.
The study, which involved 36 pairs of twins, found that those who took daily supplements of inulin or fructooligosaccharides (FOS) scored higher on cognitive tests after three months compared to those who took a placebo. In addition to improved cognitive function, the supplements also led to changes in the gut microbiome, with beneficial bacteria like Bifidobacterium being more abundant in individuals taking the supplements.
The researchers at King’s College London are excited about the potential implications of these findings for improving brain health and memory in the aging population. The study highlights the importance of the gut-brain axis and the role that gut health plays in cognitive function.
While the study focused on the benefits of prebiotic supplements on cognitive function, it did not find significant improvements in physical health, such as muscle loss. However, the researchers believe that these supplements could still benefit a wide range of people, particularly in times of financial strain, as they are affordable and readily available over the counter.
Moving forward, the researchers plan to investigate whether the effects of these supplements are sustained over longer periods and in larger groups of people. They also acknowledge that further research is needed to fully understand the relationship between gut health and cognitive function.
Overall, this study adds to the growing body of evidence supporting the connection between gut health and brain function. By exploring the potential benefits of prebiotic supplements on cognitive health, researchers hope to uncover new ways to support brain health in the aging population.
