The benefits and harms of vitamin complexes are arguing for years. Some people think that people with food does not get the required number of trace elements and to take a variety of dietary supplements. Others have questioned the idea that vitamins are safe for people and improve their health. A recent study by Scottish researchers found that excessive intake of vitamins C and E reduces life expectancy by a quarter - though not in humans and voles.
Experts observed the voles, food half of whom stepped in vitamins C and E, and the rest were fed normally. Large doses of dietary antioxidants, in theory, should slow down the aging process. Usually voles live about 500 or 600 days. However, the vitamins caused the opposite effect: in those mice who were given dietary supplements, the average life expectancy was reduced by 25%.
When we began our study, we expected lifespan of voles will increase, as it did with mice in the previous study. And they were very surprised when it did not happen - Daily Mail quoted Professor Colin Zelman from the University of Glasgow. According to him, the results show that high doses of antioxidants in different operating life in various species.
The most popular vitamins for the British are C and E and beta-carotene - a pigment found in carrots, tomatoes and broccoli. About ten million people in the UK are taking these vitamins regularly. However, experts are sounding the alarm: pills often contain a dose of selenium, which is ten times greater than the required daily norm.
There have been a lot of research, and at the best vitamin supplements does not do any good, and at worst could hurt. For example, tablets containing vitamin E may lead to the development of prostate cancer and an increased risk of mortality, - said Professor Selman.
Pinpoint the cause-and-effect relationship between antioxidant intake and the duration of a person#39;s life not given the opportunity, so we rely on the results of studies conducted on animals, - said Professor John Speakman of Aberdeen University. According to him, the results of research suggest that the action of antioxidant vitamins is necessary to pay special attention.
