Taking vitamin supplements will not lower your risk of developing lung cancer, and taking vitamin E supplements may actually slightly raise the risk, say researchers from the University of Washington.
In this study, 77,721 people aged 50 to 76 tracked their use of supplements for one decade. Multivitamins, vitamin C, vitamin E and folate supplements were analyzed to see if their use would offer protection from lung cancer.
A four year follow-up showed that none of the supplements were tied to a reduced risk of lung cancer.
People who took vitamin E at a dose of 400 IU per day for ten years had a 28 percent increased risk of developing lung cancer compared to those that didn't supplement with this vitamin.
The risk of lung cancer was particularly high in smokers who supplemented with vitamin E.
Previous research has shown that people taking beta-carotene supplements, particularly smokers, have a higher risk of developing lung cancer than those who did not.
Other studies have also failed to show that vitamin supplements can reduce the risk of stomach, colorectal, breast and lung cancers. Meanwhile, many studies have linked eating vitamin-rich foods to reduced cancer risk.
Vitamin E is a fat-soluble antioxidant that appears to protect cells from damage caused by free radicals. The recommendation for daily vitamin E intake is 15 milligrams for healthy adults. Foods that are high vitamin E include almonds, avocados, sunflower oil, hazelnuts and wheat germ.
According to the Canadian Cancer Society, lung cancer will kill about 390 Canadians every week, affecting more people than prostate and breast cancer combined.
