[Fish intake and risk of prostate cancer].
The aim of the study was to present the current state of knowledge concerning the relationship between the consumption of fish as materials rich in long chain polyunsaturated fatty acids (LC PUFA) omega-3, and the risk of prostate cancer. Many scientific reports confirm the health benefits from the consumption of fish and protective properties of LC PUFA omega-3 in relation to prostate cancer. However, there are reports that indicate a relationship of the high consumption of PUFA with the risk of prostate cancer. The way of processing and preservation of the fish, and other factors not included in previous studies, could have some importance in the etiology of this disease. High susceptibility of PUFA to oxidation changes and the technological fish processing (smoking, high-temperature cooking methods) contribute to the formation of many compounds, such as polycyclic aromatic hydrocarbons and heterocyclic amines - which may influence the formation of cancers - including prostate cancer. It is necessary to ensure an adequate amount of LC PUFA omega-3 in the diet through the consumption of proper quality fish and fish oils. Particular attention should be paid to the high susceptibility of PUFA to the oxidative processes, and the method of processing, preservation and storage of fish. Also pollution from the environment can significantly reduce the impact of health benefits of PUFA and fish, and even be the cause of cancers, including prostate cancer. Further research in this area should be more targeted to assess the impact of nutritional factors for the development of such tumors.
