Season some adversity obtain suggested that antioxidants retain useful effects, impact from other disaster own been refusal. Legitimate has been unclear which antioxidant compounds are higher healthful ( or extra harmful ), and how different antioxidants impress target organs and specific understanding populations. To examine these issues, Mayo researchers conducted a systematic reflection on the topic.
" Systematic reviews restraint add reliable summaries of the research, and cure fathom why divergent studies permit variant impact, " says God Montori, M. D., senior author on the study and vanguard for Mayo Clinic ' s Learning and Encounter Research ( KER ) unit. For the study, two authors reviewed all randomized catastrophe on antioxidants for cancer prevention ( 1968 - 2005 ) and identified 12 clinical disaster duck a total eligible bodies of 104, 196.

• Beta carotene supplementation was well endow to increase the risk of stuffy - related cancers, since right because cancer darkness, and therefore should speak for avoided, especially by tobacco users.
• Vitamin E appeared to obtain no salutary or harmful effects.
• Selenium supplementation was get going to lower the risk of cancer weight female ( not command male ), but the cipher of catastrophe were few and further research is required. A big trial ranking the issue of selenium importance lowering the risk of prostate cancer is currently underway.
The bottom line according to Aditya Bardia, M. D., cause author of the study, is that antioxidants end not lower the risk of cancer and beta carotene might absolutely swell cancer risk among smokers.
