Are we any closer to understanding the cause of prostate cancer?

Virtually all North American men will develop prostate cancer if they live long enough, and a faulty diet may be the cause. Lack of vitamin D appears to increase risk of prostate cancer because it impairs the body’s ability to remove cancer cells (Journal of Clinical Oncology, November 2005). Since calcium blocks the activation of vitamin D and milk is full of calcium, even vitamin D-enriched milk increases risk for prostate cancer.

Saturated fat and high doses of zinc also increase risk. Dietary substance which appear to reduce prostate cancer risk include lycopene, carotenoids, isoflavones, polyphenols and other phytochemicals found in vegetables; vitamin E, selenium, and omega-3 fatty acids found in seeds and fish. At this time, a diet to reduce risk for prostate cancer should include a wide variety of plant-based foods and seafood, the same diet recommended to prevent heart attacks – plus sunshine for vitamin D.
