During the several last years, the evidence of nutritional benefits of Polyunsaturated Fatty Acids (PUFA), especially omega-3, in the human body has become established. Following the epidemiological studies that suggested a beneficial role of co-3 PUFA on the prevention of cardiovascular diseases in the Eskimo population, the potential health effects of co-3 PUFA have very often been the subjects of scientific studies. Several reviews have stated the role of these PUFA on the reduction of cardiovascular disease risk, inflammation and autoimmune disorders, certain cancer forms and on the development of brain and nervous tissue in infants. Fish is the major dietary source of co-3 PUFA; therefore an increase in the consumption of fish is advisable in order to reach the recommended level of the average intake of omega-3 and to improve the omega-6/omega-3 ratio in the diet. However, it is apparently difficult to change the dietary habits towards a higher fish intake, and therefore, many products enriched with co-3 PUFA have been developed in the last years. For that reason, it is important to find abundant and profitable natural sources of co-3 PUFA.
