Will Eating Less Make You Live Longer?

Passage preview

Calorie restriction, or 'semi-starvation' as some refer to it, has been proven to extend lifespan in many living organisms from yeast to mice, but the picture for primates, including humans, is not so clear. Research published by a team at the University of Wisconsin in the United States shows that rhesus monkeys also live longer on a calorie-restricted diet. But those findings disagree with research by the National Institute on Aging (NIA) in Maryland, also in the United States. Rozalyn Anderson, of the Wisconsin team, says the research is not intended as a recommendation of calorie restriction. 'I find the idea monumentally unattractive!' she says. 'We study it because it is so effective at delaying ageing and the onset of age-related disease. It's a way to tease out what it is that creates increased disease vulnerability as a function of age.'
