Animal research shows that the composition of the gut flora, also known as the microbiome, plays a major role in the ageing process. The microbiome consists of all kinds of bacteria and other micro-organisms in our gut. This composition changes as we get older. What is striking is that adjustments which ensure a younger balance of these gut bacteria can lead to better health and a longer lifespan in older animals.
Alongside the gut flora, diet and exercise are important factors in healthy ageing. These factors also influence each other; what we eat and how active we are affects the composition of the gut flora. Keeping the microbiome properly balanced can therefore contribute to the preservation of muscle strength and brain function at a later age.
The bacteria in our guts produce substances that have a direct influence on tissues in our body, including muscles and the brain. Changes in these metabolites can pinpoint exactly why older people more frequently experience a decline in muscle strength and brain performance. By keeping the microbiome young, this deterioration may potentially be delayed.
This research underlines the importance of paying attention to gut health when ageing. It offers new insights that can help in making lifestyle choices that keep muscles and brains vital for longer. The microbiome appears to be a valuable link in the complex of healthy ageing.
