Selenium en tomaten tegen prostaatkanker.*
Selenium vermindert de kans op prostaatkanker met wel 30%. Bij prostaatkanker reduceert selenium deze met wel 50 tot 60%. Lycopeen uit tomaten geeft ook verrassende resultaten.
I am sure most of you are aware that prostate cancer is the most common cancer in men in the United States, as I address this topic frequently in my newsletters. Many well known men have been diagnosed with this disease. They include Arnold Palmer, General Schwartzkopf, ex-New York mayor, Rudolph Guilliani, Mike Milken and many others. But did you know 500 men are diagnosed with this disease EVERYDAY. And, unfortunately, many of these individuals will succumb to prostate cancer. It is uncertain why there has been an explosion in the diagnosis of prostate cancer, but the situation is far from hopeless. In the February 2003 edition of the International Journal of Cancer, researchers reported on a multi-center, population-based case-control study looking at approximately 400 men between the ages of 40 to 79 years old. It was found that those individuals with the higher levels of selenium in their bloodstream had a lower risk of developing prostate cancer by approximately 30%. This is just one of many studies that has proven, beyond a reasonable doubt, that selenium can, indeed, reduce your risk of prostate cancer. Approximately six years ago, the Journal of the American Medical Association (JAMA) reported on a multi-center, double-blinded, placebo controlled study indicating that those men treated with 200 mcg of selenomethionine reduced their incidence of prostate cancer by a incredible 63%. This same study also indicated overall cancer mortality was reduced by 50% for the selenomethionine group compared to placebo. In a subsequent study published in the Journal of the National Cancer Institute, there was again clear evidence between blood levels of selenium and a marked reduction in incidence of prostate cancer. There is currently an ongoing national study which will involve approximately 10,000 men and go on for many years to determine the true benefit of selenium and other nutrients for prostate cancer. I have asked myself on more than one occasion, why is the medical community doing another long-term study? With multiple studies all conclusively showing efficacy and safety for selenium, is another study necessary? Selenium taken properly is a totally harmless micromineral that is absolutely essential to our existence. It has been estimated that up to 90% of the population can have some degree of selenium deficiency. In the JAMA study, selenium not only reduced the incidence of prostate cancer, but also other cancers including colon/rectal and lung cancer to a significant degree. Everyone should be taking selenium. The recommended adult dose is 200 micrograms (mcg) daily. It is recommended that the organic form selenomethionine be consumed. This is the form used in the JAMA study. Do not take the inferior form found in most mass market once-a-day vitamins; they may not work. An additional nutrient that has shown tremendous benefit, especially for prostate cancer, is a carotenoid known as lycopene, which is derived from tomatoes. Clinical studies have shown some amazing benefits for this nutrient. (2003)
