1 Apr 2014 Here we show that CR significantly improves age-related and all-cause survival in monkeys on a long-term ~30% restricted diet since young adulthood. These data contrast with observations in the 2012 NIA intramural study report, where a difference in survival was not detected between control-fed and CR
A 25-year study published recently in Nature Communications has demonstrated that caloric restriction in rhesus monkeys bestowed numerous health benefits b. The NIA, however, based their feeding amounts on a standardized chart issued by the National Academy of Science. The scientists from UW concluded that this
17 Jan 2017 A 2009 image of rhesus monkeys in a landmark study of the benefits of caloric restriction. The 27-year-old monkey on the left was given a diet with fewer calories while the 29-year-old monkey on the right was allowed to eat as much as it liked. Both animals have since died of natural causes. Photo: Jeff
1 Apr 2014 “We study caloric restriction because it has such a robust effect on aging and the incidence and timing of age related disease," says corresponding author Rozalyn Anderson In contrast, the NIA monkeys were fed according to a standardized food intake chart designed by the National Academy of Science.
2 Apr 2014 A 25-year study of rhesus monkeys finds that caloric restriction promotes longevity, challenging another study that in 2012 came to the conclusion that it were fed according to a standardized food intake chart designed by the National Academy of Science, were probably also on a restricted calorie diet,
In fact, exercise activates the ancient energy sensor adenosine monophosphate kinase (AMPKinase) 12, a major facilitator of calorie restriction benefits 13. The sedentary lifestyle of the rhesus monkeys in the studies would make activation of this biochemistry unlikely. The following chart shows how calorie restriction, low
Calorie restriction (CR) is the only dietary intervention that repeatedly extends both median and maximal lifespan in a broad range of species. Although there has been considerable interest in CR and its ability to retard aging, the mechanism has remained elusive. In contrast to studies in rodent and nonmammalian systems
Primate Study Confirms Calorie Restriction Extends Life and Protects Against Age-Related Disease. Eating less can Summary. Interestingly, both the University of Wisconsin and National Institute of Aging studies indicate that greatly extended life span may be possible from moderating calorie intake. For example, five
25 Jan 2017 The study is by researchers at the University of Wisconsin–Madison and the National Institute on Aging (NIA), who have been studying calorie restriction for years. In the past, the Wisconsin team found that calorie restriction extended the lives of rhesus monkeys, but the NIA group did not. In the new study,
