Can eating less help reduce signs of aging?.
We already know eating less - and eating well - may help reduce the risk of chronic diseases like obesity, diabetes, heart disease and even cancer. But could limiting caloric intake help stall the aging process overall? According to research published this month in the journal Mollecular & Cellular Proteomics , that may very well be the case - and the results may be more effective than your local drugstore's most expensive moisturizer. In a mice study, researchers at Brigham Young University found that when ribosomes, which generate cells' proteins, slow down, aging slows as well. Reducing calorie consumption in the mice was enough to slow that production. For the study, the authors gave one group of mice unlimited access to food yet restricted the caloric intake of the other group by 35 percent. Both groups received the necessary nutrients for survival. "When you restrict calorie consumption, there's almost a linear increase in lifespan," senior author John Price, a biochemistry professor at BYU, said in a release. "We inferred that the restriction caused real biochemical changes that slowed down the rate of aging.
