Boston, MA- (8/19/98) - A new study conducted at Harvard University suggests that higher selenium intake may reduce the risk of prostate cancer. In a recent randomized intervention trial, the risk of prostate cancer for men receiving a daily supplement of 200 microg Selenium was one third of that for men receiving placebo. Harvard researchers led by Dr. K. Yoshizawa, Department of Nutrition, Harvard School of Public Health, used a nested case-control design within a prospective study, i.e., the Health Professionals Follow-Up Study, to investigate the association between risk of prostate cancer and prediagnostic level of selenium in toe nails, a measure of long-term selenium intake. The Health Professionals Follow-Up Study followed 51,529 male health professionals aged 40-75 years. In 1987, 33,737 study participants provided toenail clippings. In 1988, 1990, 1992, and 1994, follow-up questionnaires were mailed. From 1989 through 1994, 181 new cases of advanced prostate cancer were reported. Case and control subjects were matched by age, smoking status, and month of toenail return. Selenium levels were determined by neutron activation. The selenium level in toe nails varied substantially among men, with quintile medians ranging from 0.66 to 1.14 microg/g for control subjects. When matched case-control data were analyzed, higher Selenium levels were associated with a reduced risk of advanced prostate cancer (odds ratio [OR] for comparison of highest to lowest quintile = 0.49; 95% confidence interval [CI] = 0.25-0.96; P for trend = .11). After additionally controlling for family history of prostate cancer, body mass index, calcium intake, lycopene intake, saturated fat intake, vasectomy, and geographical region, the OR was 0.35 (95% CI = 0.16-0.78; P for trend = 03), the researchers reported in the Journal of the National Cancer Institute (1998 Aug 19;90(16):1219-1224). "Our results support earlier findings that higher selenium intakes may reduce the risk of prostate cancer. Further prospective studies and randomized trials of this relationship should be conducted," they said.
Background
Majestic Earth Ultimate: Selenium is referred to by many as the 'wonder nutrient.' And it's no wonder since selenium has been shown to prevent some cancers, up to 69%, strengthen the heart muscle, increase some immune factors by 79%, help prevent and treat cystic fibrosis and can lift mood and reduce anxiety and act as a powerful anti-oxidant!! Besides selenium Dr. Wallach's Ultimate Selenium contains copper, vanadium and chromium and zinc, all phenomenal nutrients in their own right: COPPER is believed to prevent and help reverse white or gray hair, wrinkles, sagging skin, varicose veins, hemorrhoids, stroke and aortic aneurism (each of which has as its origin the break down of the elastic fibers in the arteries, skin and other tissues); CHROMIUM AND VANADIUM are believed to prevent and help to reverse sugar cravings and any type of condition brought on by blood sugar instability, including hypoglycemia and diabetes; ZINC is believed to prevent and help to reverse acne, depression, anorexia, fatigue, impotence and infertility.
