Rodents, yeast, and roundworms all have something in common: They live longer when they consume less. Now a primate has joined the calorie-restriction club. After 20 long years of waiting, scientists have concluded that rhesus monkeys that eat nearly a third less food than normal monkeys age more slowly. The results come as close as any can to proving that calorie restriction could significantly slow aging in humans–even if such a lean diet would not appeal to most of us.
Researchers found that monkeys on a calorie-restricted, nutrient-rich diet (on the left in photo) were three times less likely than monkeys on a full-calorie diet (on the right) to die from age-related diseases like cancer, diabetes, and heart disease. Read more here, here or here.
