[Effect of caloric restriction on longevity].
Calorie restriction (CR) is the most evaluated nutritional intervention to increase lifespan in a variety of animal species, including human beings. CR has also been shown to delay the onset or reduce the incidence of many age-related diseases. The mechanism that could explain the effect of calorie intake on aging is related to the reduction of body fat and insulin signaling as well as reactive...
متن کاملMolecular Links between Caloric Restriction and Sir2/SIRT1 Activation
Ageing is the most significant risk factor for a range of prevalent diseases, including cancer, cardiovascular disease, and diabetes. Accordingly, interventions are needed for delaying or preventing disorders associated with the ageing process, i.e., promotion of healthy ageing. Calorie restriction is the only nongenetic and the most robust approach to slow the process of ageing in evolutionari...
متن کاملToward a unified theory of caloric restriction and longevity regulation.
The diet known as calorie restriction (CR) is the most reproducible way to extend the lifespan of mammals. Many of the early hypotheses to explain this effect were based on it being a passive alteration in metabolism. Yet, recent data from yeast, worms, flies, and mammals support the idea that CR is not simply a passive effect but an active, highly conserved stress response that evolved early i...
متن کاملEvolution of Human Longevity Uncoupled from Caloric Restriction Mechanisms
Caloric restriction (CR) and chemical agents, such as resveratrol and rapamycin that partially mimic the CR effect, can delay morbidity and mortality across a broad range of species. In humans, however, the effects of CR or other life-extending agents have not yet been investigated systematically. Human maximal lifespan is already substantially greater compared to that of closely related primat...
