Fish oils contain the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), precursors of eicosanoids that are known to reduce inflammation throughout the body, and are thought to have many health benefits. In this book, the authors present topical research in the study of the production, consumption and health benefits of fish oil, including polyunsaturated fatty acids and their dietary implications during pregnancy; plant-derived antioxidants as potential omega-3 pufa stabilisers; stability and behaviour of omega-3 food emulsions; the combined effects of omega-3 fatty acids and exercise on cardiovascular disease risk and mortality and fish oil and male fertility.
