Contradicting other research on calorie restriction and longevity, a new National Institutes on Aging study reports that rhesus monkeys fed 30% fewer calories were healthier but didn’t live any longer than a control group. The monkeys — long-lived primates similar to humans — had been followed since 1987. Those on a restricted diet did have a lower incidence of cardiovascular disease, cancer and diabetes. But that didn’t translate into longer lifespans. Researchers in a similar study at the Wisconsin National Primate Center, who have reported longevity benefits linked to calorie restriction, pointed out potentially key differences between the studies: The control group in the NIA study was given vitamin and mineral supplements and fed a limited, though higher-calorie diet. In the Wisconsin experiment, monkeys in the control group were allowed free access to food, which those researchers argued more closely resembles actual human lifestyles. — Nature…
