Scientists discovered vitamins, which increase the risk of cancer

Ученые обнаружили витамины, которые повышают риск возникновения ракаThese vitamins can be a cause of lung cancer in men.

For men taking dietary supplements containing b vitamins, 2 times higher risk of developing lung cancer.

According to scientists, this risk for men taking dietary supplements for a long time. The risk of getting lung cancer is 4 higher in those men who also smoke.

Researchers are reminded that the human body needs vitamins Vitamin B6 and B12. B6 ensures the proper metabolism of amino acids, of which proteins. Vitamin B12, or cobalamin, cyanocobalamin, in the human body activates the process of blood clotting, the metabolism of carbohydrates and fats affects blood formation. This vitamin has a positive effect on liver function, digestive and nervous systems.

These vitamins are contained in meat, fish, cheese, eggs and milk, but in the UK, millions of people take supplements with these substances. They probably expect the improvement of the metabolism and increase energy levels.

Recommended health intake for vitamin B6 is about 1.4 mg (milligrams) per day for men and 1.2 mg per day for women, while for B12, it is 1.5 mg (micrograms) daily for adults.

The researchers found that sold in the UK supplements may contain up to 100 mg B6 and 500 mcg B12.
The study examined the indicators of 77 thousand living in the USA people aged 50 to 76 years. Scientists wanted to find out the effect of the use of high doses of these vitamins on the development of cancer. Study participants provided detailed information on the use of their B-vitamin for the last 10 years, including data on the dose size.

Previously, doctors believed that supplements can help reduce the risk of cancer. But the results of this study showed more men who took high doses of vitamin B6 and B12 for ten years, were at higher risk of cancer. Were taken into account such factors as age, history of Smoking, family history of cancer and alcohol consumption.

It turned out that male smokers who took more than 20 mg of B6 per day for 10 years, three times more likely to develop lung cancer than people who did not take supplements. The risk of cancer was four times higher in smokers, men who took at least 55 micrograms B12 per day for 10 years, said Dr. Theodore Braschi from Ohio state University.

“In fact, all men who used these supplements in high doses during the decade, about twice the risk of developing lung cancer, and in men who smoked, the risk was three to four times more,” he said.

He said that a vitamin In contained doses that were “much higher than the doctors recommended daily dose”.

“Very easy to get all the vitamin B you need from eating meat, chickpeas and products, such as grains, so there’s really no reason to Supplement the intake of vitamin B supplements, especially over many years,” added Dr. T. Braschi.

But he said that most multivitamin pills do not contain such high doses of B6 and B12, therefore, the daily consumption of these drugs should not lead to the emergence of cancer cells.

Further studies will now be considered whether there was the same effect in women in the postmenopausal period or as a negative surplus of these vitamins is affected only men.
