Transact antioxidant supplements decrease the risk of cancer and deaths related to cancer? Occasion some disaster have suggested that antioxidants obtain salutary effects, collision from other catastrophe retain been rejection. Firm has been unclear which antioxidant compounds are other benign ( or larger harmful ), and how reserved antioxidants change target organs and specific patient populations. To examine these issues, Mayo researchers conducted a systematic retrospect on the topic.
" Systematic reviews care provide reliable summaries of the research, and service sense why different studies hand over other effect, " says Protagonist Montori, M. D., senior author on the study and model for Mayo Clinic ' s Enlightenment and Encounter Research ( KER ) unit. For the study, two authors reviewed all randomized calamity on antioxidants for cancer prevention ( 1968 - 2005 ) and identified 12 clinical catastrophe plant a total eligible community of 104, 196.
The second thought yielded a figure of interesting findings including:
• Overall, antioxidant supplementation did not reduce the risk of cancer.
• Beta carotene supplementation was largely commence to burgeoning the risk of sultry - related cancers, whereas wholesome due to cancer passing over, and so should show avoided, especially by tobacco users.
• Vitamin E appeared to posses no worthy or harmful effects.
• Selenium supplementation was raise to lower the risk of cancer clout female ( not string femininity ), but the figure of trials were few and further research is required. A immense trial adjudjing the flak of selenium control lowering the risk of prostate cancer is currently underway.
The bottom line according to Aditya Bardia, M. D., vanguard author of the study, is that antioxidants fulfill not lower the risk of cancer and beta carotene might in fact raise cancer risk among smokers. Selenium might obtain good properties, but undoubted cannot symbolize recommended for general convenience until also evidence is available.
