A new study finds that monkeys whose calories were restricted to 30% below normal did not live longer. But calorie-restricted monkeys avoided cancer and looked younger than the animals that ate freely.For 75 years, scientists have documented a curious fact: If rats and mice eat 30% to 40% fewer calories than usual, they live 15% to 40% longer than is typical for their species. The observation has offered humans hope that our own maximum lifespan could one day be extended, permitting people to live well past their 100th birthday.
