TweetVitamin Supplements May Increase Cancer Risk
October 01, 2004

A new analysis of previously published studies indicates vitamin supplements (antioxidant supplements) are not effective in protecting against stomach cancer and the researchers warn that they may in fact increase the risk of developing cancer.

The researchers reviewed 14 trials involving more than 170,000 people and found that vitamin supplements like vitamin A, C, E, provided no protection against a variety of cancers, including , stomach, colorectal, and liver cancer.

“We could not find evidence that antioxidant supplements can prevent gastrointestinal cancers; on the contrary, they seem to increase overall mortality," said lead study author, Dr. Goran Bjelakovic in a statement.


However, the researchers found selenium, an essential dietary mineral may be associated with a reduced risk of gastrointestinal (GI) cancers.

Among people in the trials taking antioxidants, they found a 6 percent increase in mortality compared to people taking a placebo. They also found a combination of beta-carotene and vitamin A or vitamin E increased the risk of premature death by 30 percent, and 10 percent respectively.

However, the researchers warn their study should only be viewed as preliminary, and as such, it does not provide "convincing proof of hazard".

The findings of the European researchers appears in the journal

TweetTo determine the 6% increase of mortality in cancer, you would have to find out which ppl of the 14 trials of 170,000 ppl are pre-disposed to having cancers in their family backgrounds. This would be 1 in every 16.6 ppl in the total trials. The chance of 1 in every 16.6 ppl having pre-disposed cancer that is genetic to ones family history is not a very high figure. Also it states that there is no proof that it protects or doesn't. Most articles ive read among the three A, C, and E vitamins are more to the contrairy with substantial evidence that especially the C and E are very helpfull as a supplement to the body. C with helping the heart function and circulation etc and E there has been studies that is helpful in preventing Alzhimers, not to mention the skin and vasculatory systems. Interesting read though, but unfounded, imo.

TweetLmao! No, just bored and using my calculator at work. Either that or watch some porn. Seriously though, i think some of these europeans just want some recognition, so they can put their research trials in some journals.
