Aging, Calorie Restriction, Free Radicals

STLtoday is running a long article on current research into calorie restriction and the broader relationship between food, metabolism and aging. "Cut a mouse's caloric intake by 30 percent of
what it would eat given unlimited access to food, and the mouse lives 30 percent longer." How is this relationship regulated in the body? That is the question that scientists are currently attempting to answer; there are a number of good theories on the go. Understanding the biochemical processes relating to calorie restriction will make it possible to produce therapies that have the same beneficial effects on health and life span - companies like BioMarker and Elixir are working on this.
