Since the first epidemiological studies, carried out in the ’80s, established the protective effect of fish oil against cardiovascular diseases, the interest for fish oil and omega-3 fatty acids has been highly increased as well as the demand of omega-3 enriched products and nutraceuticals. As consequence, the searching of new omega-3 natural sources, the design of competitive fish oil and omega-3 production processes and the development of different strategies for omega-3 incorporation in food products have become important fields of research all over the world. In the last years, the valorisation of fish by-products as a source of omega-3 rich oil has been considered an outstanding strategy to reduce the waste generation and increase the competitiveness in the fish industry. On the other hand, the development of green technologies based on the use of supercritical carbon dioxide has acquired an enormous interest to produce high value compounds such as omega-3 in a eco-friendly way. This book presents an application of supercritical fluids in extraction, concentration and formulation of omega-3 rich oil using fish by-products as a raw material.
Supplementation of omega-3 fatty acids is very effective in reducing oxidative stress through the improvement of antioxidant enzymes activities . Fish and flaxseed oils are nutritional supplements have a high concentration of omega-3 fatty acids.Flax seed oil is rich in alpha linolenic acid (ALA) while fish oil is rich in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). In this study we aimed to compare the effects of flaxseed and fish oils in reducing oxidative stress especially in attenuating DNA damage through the evaluation of urinary 8-hydroxyguanosine (8-OHdG) in experimental diabetes. The main finding in our study was the reduction of urinary isoprostanes and 8-OHdH , in addition to the reduction of insulin resistance during diabetes. In conclusion, flaxseed and fish oils administration has a potential effect on decreasing insulin resistance in diabetic rats through the scavenging of free radicals and increasing superoxide dismutase . This study also concluded that ,fish oil was more effective than flaxseed oil.
