Dietary Restriction and Nutrient Balance in Aging
Dietary regimens that favour reduced calorie intake delay aging and age-associated diseases. New evidences revealed that nutritional balance of dietary components without food restriction increases lifespan. Particular nutrients as several nitrogen sources, proteins, amino acid, and ammonium are implicated in life and healthspan regulation in different model organisms from yeast to mammals. Agi...
متن کاملTreating aging: progress toward dietary restriction mimetics
During the last decade, biogerontologists have labored to understand the biological basis of the aging process by studying the genes and signaling pathways that regulate it. But the last year has seen a breakthrough in a different direction: toward treatments that might slow aging by mimicking the effects of dietary restriction.
متن کاملDietary restriction with and without caloric restriction for healthy aging
Caloric restriction is the most effective and reproducible dietary intervention known to regulate aging and increase the healthy lifespan in various model organisms, ranging from the unicellular yeast to worms, flies, rodents, and primates. However, caloric restriction, which in most cases entails a 20-40% reduction of food consumption relative to normal intake, is a severe intervention that re...
متن کاملDeconstructing Dietary Restriction: A Case for Systems Approaches in Aging.
Dietary restriction is a robust and conserved intervention to slow aging and extend lifespan. In this issue of Cell Metabolism, Hou et al. (2016) use a systems biology approach in C. elegans to uncover key molecular nodes underlying the transcriptomic response to dietary restriction and predict novel regulators of lifespan.
متن کاملDietary Restriction in Drosophila: Delayed Aging or Experimental Artefact?
Lifespan can be extended by reduction of dietary intake. This practice is referred to as dietary restriction (DR), and extension of lifespan by DR is evolutionarily conserved in taxonomically diverse organisms including yeast, invertebrates, and mammals. Although these two often-stated facts carry the implication that the mechanisms of DR are also evolutionarily conserved, extension of lifespan...
