I supplement my diet with Omega-3 pills derived from fish or flaxeed. Here is more info on the positive effects of flaxseed:
Research shows that cancer risks, including the risk for prostate cancer, may be reduced by 30 to 40 percent if people ate a more plant-based diet. This healthy diet includes fruits, vegetables, whole grains, beans, nuts and seeds – including flaxseed.
“Cancer cells migrate by attaching onto other cells. The omega 3 fatty acids found in flaxseed keep cells from binding together and attaching to blood vessels,” Demark-Wahnefried says. “Lignan may reduce testosterone and other hormone levels. Lowering testosterone levels may reduce a man’s chances of getting prostate cancer.”
Demark-Wahnefried and her team learned about the potential cancer-reducing benefits of flaxseed during a study with 161 men. The men had been diagnosed with prostate cancer, but had not started treatment. Each participant ate three tablespoons of flaxseed a day. This study and its results were published in the December 2008 issue of "Cancer Epidemiology Biomarkers and Prevention."
“While our study used three tablespoons a day, men who don’t have cancer but want to try flaxseed, probably don’t need that much,” Demark-Wahnefried says. “One tablespoon a day should be fine.”
