Scientists have found out, why the low-calorie diet extends life expectancy. However, it is possible to include the cellular mechanism responsible for it without starving.
In the middle of the last century it was found out, that a low-calorie feed considerably increases life expectancy of the most different alive essences - from monocelled yeast up to primates, however, the reason of this phenomenon remained the unknown at a cellular level. American biologists research shows, that the key to a solution lays in changes of mitochondrions work, provoked by the low-calorie diet.
Scientists from Harward and American National Health Institute have managed to reveal two enzymes, which will mobilize mitochondrions, best known as “power factories”. These mitochondrions get activated during some infringements and diseases and also allow to prolong a life of the cell and to remove its destruction.
Enzymes SIRT3 and SIRT4 are related to enzymes SIRT1 and SIRT2, which importance for longevity of a cell has been established earlier. SIRT1 and SIRT2 are also known as “enzymes of youth”. These enzymes get especially active at low-calorie feeding.
Allocation of genes SIRT3 and SIRT4 not only has allowed understanding, how a low-calorie diet prolongs life to organisms. So, if you want to live a long life? is it necessary to eat low-calorie food? The answer is quite optimistic- the diet can be replaced by physical exercise, which also activates “enzymes of youth”.
