[Mediterranean diet, micronutrients and prostate carcinoma: a rationale approach to primary prevention of prostate cancer].
Cancer of the prostate is one of the most commonly diagnosed solid malignancies and the fourth leading cause of cancer-related deaths in men living in Italy. With an ageing population, the number of men living with early stages of prostate cancer is expected to increase. There is an impelling need to prevent the onset of the cancer or delay the progression of carcinogenesis in this organ. The chemoprevention of cancer is a relatively new concept defined as the administration of pharmacological agents (drug or diet-derived supplements) to prevent, delay or reverse the carcinogenesis. Epidemiological data showing ethnic and geographic variations in the incidence of, and mortality from, prostate cancer have suggested that the consumption of dietary factors may be protective. There is increasing evidence that diet (particularly dietary fat intake) may play a significant role in early prostate carcinogenesis. Dietary micronutrients and antioxidants are under intense scrutiny. These factors include the vitamin D and E, lycopene, selenium, zinc, poliphenols, isoflavonoids, and phytoestrogens (especially soy products and green tea). The old Mediterranean diet (based on cereals, vegetables, polyunsaturated fats, fruits, fish and low quantities of dairy products and meat) is now sparingly adopted because of the globalisation of the food chain which now involves also our country. Nevertheless, our traditional dietary habits are considered of great value in the prevention of cardiovascular or cancerous diseases and particularly of prostate cancer.
