Do Dietary Supplements Increas Cancer Risk?

Wednesday, May 23rd, 2012

A report in the Journal of the National Cancer Institute concluded that three supplements–beta-carotene, selenium, and folic acid–taken at up to three times their recommended daily allowances, are probably harmless but at much higher levels have been shown to increase the risk of developing a variety of cancers. Unfortunately, although Professor Byers from Colorado School of Public Health presented general terms about the subject and the report was picked up by several news sources, there was no data to back up the conclusion in this commentary piece. Thus, until I see some research that documents the conclusions presented I would tuck it in the back of my mind without accepting untilĀ  I see validation of these conclusions by research.
