Some good work from Mayo,
not always the case.
"Mayo Researchers Examine the Effect of Antioxidant Supplements on Cancer
Do antioxidant supplements reduce the risk of cancer and deaths related to cancer? That's a question answered by Mayo researchers
'Systematic reviews can provide reliable summaries of the research, and help understand why different studies give different results,' says Victor Montori, M.D., senior author on the study and lead for Mayo Clinic's Knowledge and Encounter Research (KER) unit. For the study, two authors reviewed all randomized trials on antioxidants for cancer prevention(1968-2005) and identified 12 clinical trials with a total eligible population of 104,196. The review yielded a number of interesting findings including:
* Overall, antioxidant supplementation did not reduce the risk of cancer.
* Beta carotene supplementation was actually found to increase the risk of smoking-related cancers, as well as cancer mortality, and thus should be avoided, especially by tobacco users.
* Vitamin E appeared to have no beneficial or harmful effects.
* Selenium supplementation was found to lower the risk of cancer in men (not in women), but the number of trials were few and further research is required. A large trial assessing the effect of selenium in lowering the risk of prostate cancer is currently underway."
In conclusion:
"The bottom line according to Aditya Bardia, M.D., lead author of the study, is that antioxidants do not lower the risk of cancer and beta carotene might actually increase cancer risk among smokers. Selenium might have beneficial properties, but it cannot be recommended for general use until more evidence is available."
Stay away from this crap and
eat healthily instead.
