Vitamins C and E prevent the body becomes more resistant to diabetes.
Key phenomenon may be the action of nutrients on cellular oxygen.
If you decided to work out hard to lose weight and take health days, go ahead, but beware: do not bother taking vitamin supplements at the same time. That, at least, is the paradoxical conclusion of a study coordinated by German researchers. They found that consumption of dietary supplements may put the beneficial effect of physical exercise to lose, especially as regards the prevention of diabetes.
The results of the research, led by Michael Ristow of the University of Jena, are this week's edition of the prestigious American scientific journal "PNAS". The experimental design could not be simpler: 40 healthy adult males began an exercise program, half of them received supplements of vitamins C and E, and half did not ingest the vitamins.
The researchers took muscle biopsies from volunteers to examine what happened with the metabolism of them. What usually happens is that the hammering facilitates the action of insulin in the body of people, which helps prevent diabetes, a disease more common and complicated of modernity.
It turns out that the signs of an improvement in insulin metabolism were almost reversed in people who consumed the vitamin supplements. For the researchers the "missing link" of this mysterious phenomenon may be the production of free radicals, unstable chemical forms of oxygen produced by cells during physical exertion. It turns out that vitamins C and E have antioxidant effects, ending with free radicals. That is, it is as if the body does not "feel" the effects of exercise.
It is important to remember that the researchers did not recommend the consumption of fruits, vegetables and other foods rich in vitamins. But the data show that the intake of supplements of vitamin C and E needs to be rethought
