Vitamin E And Selenium Fail To Cut Prostate Cancer Risk

A big trial fails to find confirmation for earlier reports of a reduced prostate cancer risk from selenium and vitamin E.

Initial, independent review of study data from the Selenium and Vitamin E Cancer Prevention Trial (SELECT), funded by the National Cancer Institute (NCI) and other institutes that comprise the National Institutes of Health shows that selenium and vitamin E supplements, taken either alone or together, did not prevent prostate cancer. The data also showed two concerning trends: a small but not statistically significant increase in the number of prostate cancer cases among the over 35,000 men age 50 and older in the trial taking only vitamin E and a small, but not statistically significant increase in the number of cases of adult onset diabetes in men taking only selenium. Because this is an early analysis of the data from the study, neither of these findings proves an increased risk from the supplements and both may be due to chance.

Other dietary changes to cut prostate cancer risk look more promising. Eat more fruits and vegetables and omega 3 fatty acids. Eat less saturated fats from meat.

Most studies like the E, selenium one have the participants take the supplement daily.

This seems silly to me. The dosage should be intermittent. Paleo-man's micronutrient intake, was mostly intermittent. Doesn't this seem more natural, more with the rhythm of the body?

Seems like most epidemiological studies on supplements are tainted by this fact. Am I pointing out the obvious that nobody sees?
