In this study, omega-3 fatty acids were evaluated for their protective effect against skin cancer induced by sunlight, i.e. ultraviolet radiation. The study included 42 healthy participants who were given 4 g daily of purified omega-3 polyunsaturated fatty acids, eicosapentaenoic acid, (EPA) or monounsaturated, oleic acid, for 3 months. Supplementation of the omega-3 fatty acid eicosapentaenoic acid reduced markers of DNA damage, thus indicating a beneficial effect of EPA in the protection of skin cancer. Further details can be found in the study.
