Pounding the pavement could be a sign of healthy ageing. In a study of more than 1000 45-year-old New Zealanders, those with the slowest gait (1.2m per second) had poorer physical health. They also had accelerated ageing, with facial, it was discovered that butyrate, a short-chain fatty acid produced in the gut, can alter ageing. Butyrate is produced by fermentation of dietary fibre in the gut, which in turn stimulates production of a pro-longevity hormone that regulates energy and metabolism. In the study, increased butyrate lead to the production of neurons in the brain. The results may lead to food-based treatments to slow the ageing process.
