Eat Less, Live Longer

WASHINGTON, D.C.: For the first time, US researchers have found evidence suggesting people may live longer by eating fewer calories each day, a dietary restriction that already has shown in experiments to extend the lives of laboratory animals by up to 40 per cent. Even if the evidence proves to be correct, it's unknown how much extra time people might live. Laboratory studies for decades have shown that reducing the calories fed to lab mice and rats enabled the animals to live much longer, but the same effect has not been positively demonstrated in monkeys or in humans. Now, George S Roth and his colleagues at the National Institute on Aging say they have preliminary evidence that biological changes that help create superaged rodents may also work in humans.
