Guest guest Posted August 5, 2003 Report Share Posted August 5, 2003 August 4, 2003 NUTRITION NEWS FOCUS " Nutrition news is important. We help you understand it! " Today's Topic: Zinc and Your Prostate Prostate tissue concentrates zinc, so it is logical to assume that zinc is involved in prostate health. A new study finds that men who take high levels of supplemental zinc are at increased risk of prostate cancer. From about 47,000 men, over 2,900 cases of prostate cancer were observed during 14 years of followup. Use of zinc supplements up to 100 mg per day was not associated with prostate cancer, but in men who consumed more than this level, there was a 229 percent increase in risk. The longer zinc was used and the more taken, the greater the risk of advanced prostate cancer. There were 412 men in the group who consumed more than 100 mg of zinc. The study was published in the July 2, 2003 edition of the Journal of the National Cancer Institute. http://jncicancerspectrum.oupjournals.org/cgi/content/abstract/jnci;95/13/1004 > HERE'S WHAT YOU NEED TO KNOW: One hundred mg of zinc is eight times the recommended amount. Men who took in the most zinc also used significantly more calcium, vitamin E, iron and folate. It is possible that one of these nutrients played a role in the findings. Although this type of study cannot prove a cause and effect relationship, it is enough to question such high intakes of zinc. ******************************************************************** Quote Link to comment Share on other sites More sharing options...
