Study Sheds Light On Why Low-Calorie Diet Slows The Aging Process

July 16, 2010: 10:58 AM EST
A British study in mice shows that a low-calorie diet slows the aging process because it has a beneficial effect on cell senescence, the point when a cell is no longer able to replicate. Scientists found that fewer senescent cells accumulated in the livers and intestines of the mice as the animals aged. They also found that the protective ends of chromosomes, known as telomeres, of the mice were better maintained despite their aging. The fact that the adult mice consumed a restricted diet for only a short time indicates that the benefits of a very low calorie diet can be gained at any time. It can lead to a longer lifespan and reduced incidence of age-related diseases, even if the diet is adopted later in life, the researchers concluded.
