Our laboratory is focused on life span extension through dietary manipulation. Since 1936 it has been know that life span can be extended by 40% or more by reducing the caloric intake in a variety of animals. More recently, we have demonstrated that similar gains in life span can be attained by feeding rats a diet deficient in the essential amino acid methinonie. Animals on this diet have several advantages over calorically restricted animals, not the least of which is that they are fed ad libitum, and are group housed. This effect of methionine restriction does not appear to be the result of caloric deprivation, since the animals actually consume more food and energy on a body weight basis than do control animals exposed to "normal" methionine intake.
