More evidence you should just eat food with vitamins rather than take supplements

For example, observational studies of people who eat foods rich in antioxidants like vitamins A and E and beta-carotene have suggested these substances improve health. But well-designed clinical trials found increased death rates among people who take them as supplements. And while low vitamin C doses can suppress harmful free radicals, very high doses promote their formation. The initial promise that vitamin E could protect against heart attacks and cancer failed to stand up to scientific scrutiny, which instead found that it increased the risk of heart failure.

In my opinion, death has a lot to do with the individual and not solely based on what supplements people are putting in their body. How are death rates based on the use of supplements even measurable? There are way too many other factors that come into play (patient history, genetics, etc).
