We need to eat less. It is this idea that researchers at Temple University, located in Philadelphia, are trying to bring to humanity. If earlier scientists only guessed that moderate consumption of food directly affects the increase in life expectancy, now they managed to prove it in a scientific way. As it turned out, the key to the clue was for a long time hiding from our eyes in the genes.
Scientists have managed to solve their puzzle for decades and come to the conclusion that epigenetic changes occurring in the organisms of living things can be slowed down by a diet with a low calorie content. In their study, a group of university researchers concentrated on studying the DNA mimicking process, the chemical activity responsible for the severity of certain genes.
Using deep sequencing technology, researchers carefully studied the relationship of the epigenetic shift occurring with age in the organisms of various animals and related the results to the duration of their life. It turned out that the more epigenetic changes occurred in the body, the shorter the life span. After this, the scientists moved to the second phase of the experiment: they tried to find out whether these changes are related to diet and reduced caloric intake.
Laboratory mice and experimental monkeys that were planted on a low-calorie diet showed a dramatic decrease in epigenetic changes compared to a control group that fed more caloric foods . As a result, dieted monkeys on the basis of blood tests were 7 years younger than those who used ordinary food. In the case of mice, the results of the comparison were even more pronounced. The results of the study were published in the journal
Scientists are firmly convinced that such an effect on the body diet will have in the case of people. Although on the man such experiments have not yet been conducted. Reducing the calorie content of food will allow many people to avoid the numerous age-related diseases, as well as significantly increase life expectancy. It remains only to make a serious effort and give up the temptation to eat something incredibly greasy and harmful.
