Could a low-cost supplement help protect our memory as we age? A new study suggests that daily doses of plant-based fibres might give the brain a gentle boost, particularly in older adults.
How gut health may influence the brain
Researchers have long suspected a connection between the gut and the brain, often referred to as the ‘gut-brain axis’. Now, scientists believe that prebiotic fibres, such as inulin and fructooligosaccharides, could support memory by feeding beneficial gut bacteria. These bacteria, when well-fed, may send signals that positively influence brain function.
Study uses twins to test brain health link
At King’s College London, a group of twins aged over 60 took part in a three-month trial to explore this link. One twin in each pair took a daily prebiotic and protein powder, while the other received a placebo. At the end of the study, those who had taken the prebiotic supplement performed slightly better on memory tests. Researchers also noted changes in gut bacteria, particularly a rise in bifidobacterium. This has been linked in past research to improved cognitive function.
Early findings show promise, but more research is needed
While the results are encouraging, experts stress that this was a small-scale study. It is not yet clear how long the benefits might last or whether they apply to everyone. Physical improvements, such as muscle strength, were not seen, and most of the participants were women. Larger, longer-term trials will be needed to confirm whether these supplements can reliably support brain health in older people. Companies such as https://www.vitortho.co.uk/ sell an array of food supplements that could support brain health.
Could food really support long-term brain function?
The idea that what we eat could affect how we think isn’t new, but this study gives it fresh backing. By supporting gut health through prebiotics, we might be able to influence memory and thinking as we age. The NHS has a list of foods that can support digestion and improve gut health.
Eating to support your gut may end up being one of the simplest ways to protect your mind.
