Hamburger and Antioxidants

Eat fewer calories - will live longer. It is practically proved, but the molecular basis of this effect is only now beginning to open.

Many experiments conducted on laboratory experimental - from mushrooms and fish to rats and primates - reliably indicate that the decrease in caloric intake at normal consumption of vitamins and minerals slow the processes associated with aging of cells and body. There is evidence, and that a similar effect diet has on people. On the other hand, the specific physiological causes of this healing effects remain unknown.

Only recently, a group of Swedish scientists Nistroma Thomas (Thomas Nyström) established one of the mechanisms that run a low-calorie diet and lead to a number of pleasant consequences for health. Using yeast as a model. Sacharomyces. They were able to show that restricting caloric intake of nutrients stimulates the activity of the enzyme piroksiredoksina I (Prx1). This protein plays an important antioxidant role of the cell, protecting it from oxidation of the structure of hydrogen peroxide, which is considered one of the essential factors of aging.

Researchers found that during the aging Prx1 itself naturally damaged and lost productivity. However, low-calorie diet leads to increased synthesis of another enzyme,. Srx1. , Which restores the damaged molecular piroksiredoksina. By the way, exactly the same effect can be achieved without suffering from the diet - a simple injection of additional protein in the cell Srx1.

Michael Moline (Mikael Molin), one of the authors of the study, explains: ... And it can be assumed that the effective restoration of the damaged enzyme Prx1 may be, if not eliminate, significantly delay the appearance of ... Add that piroksiredoksiny prevent oxidation and damage not only nucleic acids, and proteins, slowing down the process of aggregation, which is also associated with a number of age-related disorders, including those affecting the nervous system - such as Alzheimer's and Parkinson's.

However, non- fat food - is not a panacea. Yes, and cholesterol is not as terrible as he is painted. Read about it in our article ...
