Dietary restriction DR is a robust nongenetic, nonpharmacological intervention that is known to increase active and healthy lifespan in a variety of species. Despite a variety of differences in the protocols and the way DR is carried out in different species, conserved relationships are emerging among multiple species. A report of lifespan extension in rapamycin-treated mice suggested that the TOR pathway, a conserved mediator of DR in invertebrates, may also be critical to DR effects in mammals. These studies complement each other and together aim to deliver the promise of postponing aging and age-related diseases by revealing the underlying mechanisms of the protective effects of DR. Here, we summarize a few of the reports published in that we believe provide novel directions and an improved understanding of dietary restriction. Dietary restriction DR is defined as a reduction of particular or total nutrient intake without causing malnutrition. Dietary restriction in this broad sense includes caloric restriction CR, in which total food intake is reduced, as well as studies involving the restriction of major dietary components protein, lipid or carbohydrates or temporal variations of food intake intermittent fasting. Understanding the molecular mechanisms of how DR slows aging and age-associated diseases has gained pace in the last few years. This is largely attributed to the utilization of the powerful genetic tools that are available in simple and short-lived model organisms like Saccharomyces cerevisiae S. These studies lay a foundation for the examination of conserved basic mechanisms in mammals. Insightful studies in mammalian systems are taking us closer to the goal of being able to employ our understanding of DR to postpone aging and age-related diseases in humans. In practice, CR is easier to implement than DR.
