Eat less and keep your mind young and fresh

Eating less may keep the mind young, according to Italian scientists who reported on Monday they have discovered the molecular process by which a strict diet may save the brain from the ravages of age.

The research, published in the US journal the Proceedings of the National Academy of Sciences, is based on a study of mice that were fed a diet of about 70 percent of the food they normally consumed.

Scientists found the calorie-restricted diet triggered a protein molecule, CREB1 that activates a host of genes linked to longevity and good brain function.
