Vitamins reduce the benefits of exercise

Vitamins reduce the benefits of exercise
If you do physical exercises to improve metabolism and prevent diabetes, you better refrain from antioxidants such as vitamins C and E, says the newspaper The New York Times, citing figures from the study.

It is known that physical exercise brings many health benefits, in particular, affect the susceptibility to insulin. Doctors often advise people, prone to diabetes, do more exercise, noted author Nicholas Wade.

But physical exercise to the same cause muscle cells metabolize glucose by combining carbon with oxygen and removing energy. In the process, some highly active oxygen molecules are released and commit chemical attack on all the tissues in its path.

These active compounds of oxygen known detrimental effects on the fabric, the article says. The number of oxygen damage in the body increases with age, and, according to the theory of aging is the main cause of decay of the body.

The body has its own defense system to combat the destruction of oxygen, but it is not enough. So antioxidants, which block the reactive oxygen compounds, could be a solution.

Scientists led by Dr. Michael Ristou, a nutritionist from the University of Jena in Germany, tested this hypothesis on a group of young people who do physical exercises. Half of them received moderate doses of vitamins C and E.

They found that in class, take vitamins, has not improved sensitivity to insulin and the mechanism of natural protection the body from oxygen damage is practically not enabled.

According to scientists, the reason is that the active oxygen compounds - an inevitable product of exercise - are a natural trigger to start the mechanism. Vitamins, destroying active oxygen, blocking the natural reaction of the organism.

"If you exercise for health, you should not take a large number of antioxidants," - noted Ristou. In addition, antioxidants in general, cause the reaction, which hinder the positive effect of exercise, diet and other interventions.

"If people do exercise, it blocks the effect of insulin in the metabolic response", - added study co-author, Dr. Ronald Kahn of Joslin Diabetes Research Center in Boston, speaking of the impact of vitamins.
