Diet & Longevity

Researchers who have studied the effects of caloric restriction (CR) are convinced that a diet limited in calories but possessing all necessary nutrients can extend the lifespan of a variety of organisms, possibly even humans.

According to a online report at iangoddard.net, "CR not only extends the lifespan of laboratory animals but also reduces the incidence of virtually all diseases of aging such as cancer, heart disease, diabetes, osteoporosis, auto-immune disorders, neurological decline and diseases such as Alzheimer's and Parkinson's."

Scientists think the anti-aging mechanism triggered by CR is an enzyme called Sir2. In a study conducted by the University of Connecticut Health Center, researchers discovered that an increase in Sir2 levels extended the lifespan of fruit flies. These findings could one day lead to the development of a drug that would extend one's longevity without having to adhere to a strict CR diet.
