Vitamins' may shorten the life " Bashny.Net

Scientists claim that vitamins not only prolong life, but on the contrary, can lead to premature death.

A team from the University of Copenhagen studied the results of 67 scientific studies. On this basis, they concluded that there is "compelling evidence" to support the opinion that antioxidants help to increase life expectancy.

On the contrary, they argue, vitamins A and E interfere with the body's natural defense mechanisms.

"In addition, beta-carotene, vitamin A and vitamin E seem to increase the risk of premature death," - the report says Danish scientists.

From 817 scientific research in this field, they selected a few dozen papers on the effects of beta-carotene, vitamins A, C and E and selenium. It is they who, in their opinion, the most objectively reflect the overall picture of the use of food additives.

It is believed that these additives may prevent the "oxidative stress" in the tissues of the organism by destroying the free radicals, which are believed to cause this.

"Oxidative stress" is observed in some serious diseases, including cancer and heart disease.

Good nutrition
Total participated in the study 233 thousand. People - both sick and healthy - take nutritional supplements.

Taking into account various factors, as well as to exclude from consideration a further 20 works, Danish scientists have concluded that vitamin A increases risk of premature death by 16%, beta-carotene - 7%, and vitamin E - 4%.

Vitamin C seems to have no effect on life expectancy and, according to scientists, more research is needed on the effect of vitamin C and selenium.

In carrying out the mandate of doctors,
Three times a day took out the vitamin,
Talking to himself: "Be Healthy!».

How they are life-threatening.

Getting the remnants of the mind,
Medicine in the face, I toss the pills
With an angry exclamation: "Eat them yourself!».
