Vitamin E
Reports says Vitamin E supplements could cause increase in lung cancer. The study behind the news report looked at the use of supplemental vitamins (multivitamins, vitamin C, vitamin E and folate) and new cases of lung cancer. Overall, the study found no protective effect of supplements on lung cancer. It also found a barely significant increase in risk of lung cancer associated with vitamin E supplementation. The increased risk was small – a five per cent increase in risk for every 100mg of vitamin E taken per day over 10 years – and this translated to a small increase in the participants with lung cancer. By far the largest predictor of lung cancer from this large study was smoking, with the vast majority of cases occurring in current or past smokers.
