Moscow, November 20 – RIA News. People whose diet contains a lot of sugars and small proteins should be less likely to suffer from older descentia and problems with memory acity in their advanced years of life. This conclusion was made by scientists who published an article in the Journal Toll Reports.
"There is no cure for dementia so far – we can slow down, but do not stop it. So, discovering a diet that can improve brain function at age has become an extremely important and joyful event for us," said Devin Wahl The University of Sydney (Australia).
Flour of choice
Today, most scientists believe that diet and safe foods have a strong impact not only on a person's weight, but also on the health of his brain, blood vessels, heart and other key organs of the body.
For example, recently scientists have shown that eating large quantities of olive oil and Mediterranean dishes significantly reduces the chances of death from a stroke or heart attack, and a much larger salt in food, on the contrary, the health of heart and blood vessels.
Until biologists came to a consensus about what types of nutrients – proteins, fats, or carbohydrates – most affect the health of the body and brain, and how they change their work. Hundreds of experiments conducted in recent years have led to conflicting results.
For example, there are hints that a diet rich in supposedly unhealthy fats and proteins does not harden, but improves human health and prolongs life. On the other hand, almost all scientists agree that the typical "Western" food has the worst effect on health and contributes most to the development of atherosclerosis, cancer and other serious diseases.
Roller and his colleagues found one of the most unexpected advantages of another "harmful" diet with many carbohydrates, observing the lives of several hundred older mice who ate different types of food. Some of them, as the researchers do, are on a special diet, the number of calories was 20% less than the norm.
Food for the mind
Scientists are interested in how the transition to a new type of food influences the work of the genes that control cell metabolism, and how these changes affect the brain's brain and their intellectual abilities. To do this, scientists launched mice in a labyrinth, from which there were many exits marked with different smells, colors and other marks, and how quickly they found a way out of it.
As a rule, young rodents memorize the position of the "correct" passage on the first or second day of the experiment, and subsequently always move to it without error. With the development of age problems with memory and sharp thinking, they learn this skill only on the fourth day of training.
It turned out that the diet strongly influences the success in the test, and not only rodents who have received a small number of calories manifested in it, but also paradoxically, mice that feed on almost pure carbohydrates.
They memorized the way out of the labyrinth not on the fourth, but on the third day of the experiment, and in general they reached it faster than older animals on a regular diet. The changes in their behavior, in turn, were due to the fact that their Hippocampus, the memory center, almost did not reduce the band and did not reduce the level of activity in comparison to youth.
"The most effective diet of our list contains only 8% of proteins and 80% of carbohydrates is very similar to what food is consumed by the people of Okinawa, one of the major" longevity zones "on the ground. Sweet potatoes with a lot of starch that feeds our mice, "David Le Coutur, college Valya.
