Reduced risk of prostate cancer by vitamin E
Already about ten years, Finnish researchers have demonstrated that the intake of vitamin E may reduce the risk for prostate cancer. According to new results but this effect does not last.
published in 1994 in the ATBC trial (Alpha-Tocopherol, Beta-Carotene Cancer Prevention) almost 30,000 smokers received (men only), 5-8 years 50 mg daily or 20 mg vitamin E Beta carotene, or both, or a placebo (a dummy treatment). About 18 months after you start taking vitamin E reduce the risk for prostate cancer was decreased. Beta carotene, however, showed no effect. To investigate the long-term effects, the study participants were followed up. Now the results of a 6-year follow-up have been published: After the preventive effect of vitamin E after you stop taking disappears, he has been going strong in the first three years back. A general recommendation to take a daily vitamin E for the prevention of prostate cancer, but it can not be derived. To this end, further studies are necessary, as the final of the scientists. backdropin the body caused by oxidative processes constantly called free radicals. These are highly reactive substances that can damage cells. Therefore, they are associated with various diseases, including cancer. Although the body has efficient methods to make these hazardous substances harmless. Not even vitamin C (ascorbic acid), vitamin E are (alpha-tocopherol) and beta carotene involved, which is why they are called antioxidants. example, however, environmental factors (eg UV radiation, air pollution), nutrition (eg vitamin-poor diet) and beverages (eg, alcohol , smoking) reinforce or weaken their defense the formation of free radicals. This is called oxidative stress, which promotes the development of diseases. For this reason, has been studied for years in large-scale studies of whether increasing intake (supplementation) of antioxidants against diseases such as cancer or cardiovascular disease protection. The results are in part contradictory and controversial. Because the studies differ in their methods and can not be so easily compare: On the ATBC study involved smokers, for example, only in part.
