Mixed results for dieting monkeys

摘要

For more than 75 years, we have known that reducing food consumption increases longevity and preserves various aspects of health in mice and rats. For many researchers, these observations offered an investigational tool for probing underlying mechanisms of the ageing process. For other researchers and for the public at large, however, the observations suggested the more immediate hope that calorie restriction might improve health and extend life in humans - the fountain of youth could be as close as one's dinner plate.
