Do prebiotics boost memory in over-60s?

Prebiotics, dietary fibers that promote the growth of beneficial gut bacteria, are increasingly being studied for their potential effects on health, including cognitive function in older adults.

There is some evidence that prebiotics may have an indirect positive effect on the brain, even in people over 60, via the gut-brain axis. Prebiotics stimulate the growth of beneficial gut bacteria. These bacteria produce metabolites such as short-chain fatty acids (e.g. butyrate), which have an anti-inflammatory effect.

Chronic inflammation is often associated with cognitive decline. Prebiotics may help reduce inflammation, which may help support brain health.

Although the direct effects of prebiotics on memory in people over 60 are still in the early stages of research, there are some findings that suggest a positive effect. Small studies have shown that improvements in gut health due to prebiotics may be associated with improvements in memory.

Natural sources of prebiotics include garlic, onions, asparagus, bananas, artichokes, and whole grains like oats.

While there is some promising evidence that prebiotics may have a positive effect on brain health in people over 60, more large-scale, long-term research is needed to definitively confirm these effects. However, incorporating prebiotic foods into a healthy diet can’t hurt.
