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 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 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 کاملAppetite for reproduction: dietary restriction, aging and the mammalian gonad
The major physiologic theory of aging, the disposable soma theory, links dietary restriction (DR), also known as calorie or food restriction, to prolonged lifespan and makes specific predictions about the effects of aging and DR on reproduction. A recent study in BMC Biology profiling the effects of aging and DR on gonadal gene expression provides novel molecular evidence that has a significant...
متن کاملVisions & Reflections (Minireview) Ruminations on dietary restriction and aging
Calorie restriction has been known formany decades to extend the life span of rodents. Since the more recent discovery that a long-term reduction in nutrient intake also extends life span in nearly every invertebrate model organism used for aging research, the mechanisms behind the longevity benefits of this intervention have been under intense scrutiny. While models have been developed in yeas...
