|VITAMIN E LOWERS RISK OF ADVANCED PROSTATE CANCER|
"Vitamin E and selenium supplementation and risk of prostate cancer in the Vitamins and lifestyle (VITAL) study cohort," Peters U, Littman AJ, et al, Cancer Causes Control, 2007 Oct 18
35,242 men were looked at in this prospective study. The results indicated that long-term Vitamin E supplementation could lower the risk of advanced prostate cancer. Long-term in this context means greater than 10 years. Vitamin E use was assessed using a detailed questionnaire at baseline. During 2-4 years of follow-up, 830 new cases of prostate cancer were identified. A significant inverse association was observed between long-term vitamin E supplementation and risk of advanced prostate cancer (regionally invasive or distant metastatic).
The10-year average intake was at least 400 IU/day supplemental vitamin E. This intake was associated with a 57% reduced risk of advanced prostate cancer, compared to no intake of vitamin E supplements. It appears that long-term supplementation with vitamin E may lower risk of advanced prostate cancer in men.
Prospective studies always leave a lot of questions unanswered. What was the form of Vitamin E used? What were the other significant lifestyle parameters? Were other supplements used? Besides prostate cancer what other diseases developed in these men?
Even so, this is a great little piece of work. Anyone who takes Vit. E usually takes 400 IU-it's a common daily dose. What did these men do that it was so helpful for them? It's certainly something to consider if there is prostate cancer in your family.
