There is insufficient evidence to show that caloric restriction helps slow aging among people. Although observational studies have pointed out that average weight people tend to live the most, there are scientists who believe that longevity taken soon by genetic factors.
Primates WNPRC control group, ate large quantities of food compared to those in NIA study, which received fixed gate. For these reasons, it is possible that study results WNPRC be due to a control group of individuals who eat unhealthy, rather than the group that was “longevity diet” caloric restriction.
On the other hand, scientists who study caloric restriction in mice confronted with conflicting results, which we attributed to genetic diversity. It is possible that genetic variations explain some contradictory results found in the two studies in monkeys, apes NIA given that originated in India and China, while those of WNPRC came only in India.
Over time, several studies have supported the idea that caloric restriction helps extend life. Such experiments were performed on cylindrical worms and rats. More recently, molecular studies have suggested that caloric restriction, or the use of compounds that mimic this process could trigger a cascade of changes in gene expression, a phenomenon that would lead to slower aging.
New news coming from scientists could to please those who like to indulge in calories rich food. Recent research conducted by the National Institute for the Study of Aging (NIA), from Maryland, suggest that caloric restriction does not help to extend the life of primates.
