Nutrition and prostate cancer: a proposal for dietary intervention

In this review, we consider the evidence from geographic and metabolic epidemiology and laboratory studies with human prostate cancer cell lines and animal models that emphasizes the need for the development and implementation of a dietary intervention trial in prostate cancer patients. It is concluded that such a trial should include a reduction in total fat consumption to 15% of total calories and supplementation of the diet with selenium, vitamin E, and a soya product. The low-fat intervention would provide an appropriate reduction in the intake of any specifically targeted dietary fatty acid, such as linoleic acid or alpha-linolenic acid.
