5 Prostate Cancer Prevention Tips
Article by Pete Sharpe
Prostate cancer is one of the largest cancer killers on earth today and affects more than 500,000 men worldwide every year. This number is expected to increase in the future along with our aging population.
Here are 5 prostate cancer prevention tips.
1 – Understanding Antioxidant Levels for Protecting Your Prostate
A recent prostate cancer study provides evidence that oxidative stress is one important mechanism in prostate cancer development and progression. Stress can restrict the flow of blood and energy levels in ones body. This stress related damage sets the stage for enlargement of the prostate and possibly cancer.
However, adequate intake of antioxidants, such as selenium, lycopene and vitamin E, may help aid in cancer prevention, said Dr. Haojie Li, a researcher at the Brigham Women’s Hospital and Harvard Medical School.
Dr. Li’s team decided to check for variants of the gene that codes formanganese superoxide dismutatase (MnSOD), an important enzyme thatworks as an antioxidant in human cells to defend against disease.
This study, as well as other epidemiological studies, encourages dietary intake of nutrients such as lycopene from tomato products, or supplements vitamin E and selenium can be a great benefit in prostate cancer prevention.
High levels of selenium, vitamin E and carotenoid lycopene have beenshown to reduce prostate cancer in one out of every four Caucasian males, or those who inherit a specific genetic variation that is particularly sensitive to oxidative stress, say US researchers.
Conversely, if carriers of this genetic variant have low levels of these vitamins and minerals, their risk of aggressive prostate increases substantially, as great as 10-fold, over those who maintain higher levels of these nutrients, researchers who write in issues of Cancer Research have reported.
2 – Certain Omega 3 Fatty Acids Protect Your Prostate -
Men with high intakes of the omega-3 fatty acids eicosapentaenoic acid (EPA)and docosahexaenoic acid (DHA) may have a reduced risk of prostate cancer, according to researchers from the National Institutes of Health’s National Cancer Institute (Am J Clin Nutr, 80, 1:204-16, 2004). Increased dietary intake of alpha linolenic acid (ALA), however, may increase the risk of advanced prostate cancer.
The researchers found men with the highest intake of EPA and DHA combined had an 11-percent reduced risk of developing prostate cancer and a 26-percent reduced risk of developing advanced prostate cancer. Researchers also found while dietary intake of ALA was unrelated to the total risk of developing cancer. Its consumption significantly increased the risk of developing advanced prostate cancer.
3 – A High Fiber Diet Helps in Protecting Your Prostate -
MILAN, Italy- More recent research published in the March 20 edition of the International Journal of Cancer (109, 2:278-280, 2004)(www3.interscience.wiley.com/cgi-bin/abstract/106586506/ABSTRACT) shows vegetable fiber may lower the incidence of prostate cancer. Researchers noted this is the first study to look into fibers role in prostate cancer. In an 11-year multi-centercase-control study, researchers investigated 1,294 men with incident, historically confirmed prostate cancer and 1,451 controls with acute nonmalignant conditions. They found the risk for prostate cancer was inversely related with soluble fiber, cellulose and vegetable fiber, with vegetable fiber seen as the most protective! Men who consumed the highest amount of vegetables were 18-percent less likely to develop prostate cancer than those who ate the least amount of vegetables. These relationships were consistent across all ages, family histories,body mass indexes and education.
According to a Reuter’s write-up, researchers reported that because vegetables were seen to provide the most benefits of all the fibers investigated, it may be possible that some of their other nutrients could be the reason behind their prostate cancer prevention benefits.
4 – Green Tea May Protect Your Prostate -ANAHEIM, Calif.–After one year taking green tea catechins (GTCs), only one in a group of 32 men at high risk of developing prostate cancer were diagnosed with the disease, compared to nine out of 30 in a control group. Italian researchers found epigallocatechin gallate (EGCG)in GTCs targeted prostate cancer cells for death, without damaging benign controls. The results were reported at the 96th Annual Meeting of the American Association for Cancer Research in Anaheim, Calif.
Italian researchers from the University of Parma, University of Modena, Reggio Emilia and Saverio Bettuzzi found Clusterin, a gene involved in prostate apoptosis, a possible mediator of catechins’ action. EGCG induced death in cancer cells, not normal cells, inducing Clusterin expression, said Bettuzzi. The research subjects were aged 45 to 75 with high-grade prostatic intraepithelial neoplasia–malignant lesions that are prostate cancer precursors–forwhich no treatment had been given, and who were not consuming green tea, tea-derived products or antioxidants, or following anti-androgenic therapy. Intervention subjects received 200 mg of GTCs (50 percent EGCG). The 30 percent incidence rate of prostate cancer in thecontrol group was consistent with previous findings, as was the absence of significant side effects or adverse reactions among the treated group.
5 – Eating Right to Protect Your Prostate –
Ideally, people would get all the nutrients and vitamins they need from food. Unfortunately many people have a nutrient deficit diet because our food products are designed to produce good-looking items that don’t spoil on the way to the consumer instead of nutrient-packed, healthful foods. That’s why most people must turn to supplements. Liquid and natural supplements are much easier for our bodies to process, and are more easily absorbed. Supplements that specifically benefit the prostate include zinc, kelp, nettles, green teas, pygeum, saw palmetto, and avena sativa.
Zinc strengthens the immune system, is vital for strong bones and reproduction, and regulates both sugar and blood cholesterol. Kelp: A seaweed rich in minerals and iodine that help to prevent and treat prostate cancer. Nettles: Contain iron, vitamin C, and other nutrients that can strengthen the prostate. It can be taken in a variety of forms. Green tea: Catechins found in green tea may help the prostate, although it is not totally proven. Pygeum: This herbhas been used to treat diseases of the prostate and urinary tract in Europe for many years. It has been shown to shrink enlarged prostates in many studies. Saw palmetto: This herb is believed to shrink enlarged prostates and to lower PSA. Avena sativa: Rich in calciummucin and silicic acid, avena sativa tones the nervous system.
Dietary recommendations for the prostate are to eat a lot of vegetables, fruits, legumes (peas, beans, and lentils) and fresh fish. Fish contains essential fatty acids the body uses to produce prostaglandins, which keep the immune system strong. Eat whole grainin moderation, rather than refined, and choose organically grown foods whenever it’s possible. Avoid fatty meats, since high-fat diets have been linked to prostate cancer, other cancers, heart disease, and numerous other medical problems. Stay away from refined sugars, salt, hydrogenated oils, canned, packaged, or otherwise processed foods. Cut down your consumption of dairy products, soda pop, alcohol, black teas, and coffee. Remember a healthy diet with moderate exercise can go a long way to prostate cancer prevention.
