PROSTATE CANCER AND DIET

All men will develop prostate cancer if they live long enough and lack of vitamin Dmay be the most likely cause. For the first time, Harvard researchers offer a logical explanation for the very high incidence of prostate cancer (3). Prostate cancer is most common in men who eat a high fat, high-saturated fat, high -polyunsaturated fat and high partially hydrogenated fat diet (1), found in meat, chicken, dairy products and extracted vegetable oils. Prostate cancer is also very common in men who eat a high-calcium and low vitamin D diet (2). For example, diary products increase risk and vitamin D supplements reduce risk.

A high-meat and high dairy diet lowers blood levels of the active form of vitamin D [1,25(OH)(2)D]. Meat is loaded with phosphorous, and diary products are loaded with calcium and phosphorus which lower blood levels of the active form of vitamin D called 1,25(OH)(2)D vitamin D. Sulfur-containing amino acids from animal protein make blood acidic which suppresses active vitamin D production. Additionally, high fructose consumption in sugary products lowers blood levels vitamin D (2,3). So the combination of meat, chicken, diary products, calcium supplements and lack of vitamin D combine to increase a man's chances of getting prostate cancer.

The data suggest that dietary fat, both saturated and unsaturated, are associated with an increased risk for prostate cancer in a low risk population.
