Condition: Fatty Acids, Omega-3 · Sponsor: Universidad de Granada
The long-chain polyunsaturated fatty acids (PUFA) of the n-3 or omega-3 series and, in particular, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), both derived from the essential fatty acid alpha-linolenic acid, are part of all cell membranes and from them derive numerous compounds such as prostaglandins, thromboxanes, leukotrienes, resolvins, protectins and maresins that play numerous biological roles, most notably in the control of body homeostasis, blood coagulation and inflammation. The omega-3 index is a biomarker that reflects the nutritional status of n-3 PUFA, as well as cardiometabolic risk and cardiovascular health. This index is determined as the sum of the percentages in weight of EPA and DHA over the total of fatty acids present in the erythrocyte membranes. Previous studies carried out in Spain, such as ANIBES, indicate that in adults, and especially in those over 60 years of age, the intake of n-3 PUFA is well below the international recommendations, which is directly related to a low intake of fish, since both EPA and DHA are abundant in oily fish. However, in Spain, the nutritional status of omega-3 PUFA and their possible association with a higher prevalence of cardiometabolic risk is unknown, as well as the relationships with food intake and the cultural and socioeconomic status of the population. Therefore, the main objective of the present study is to evaluate the omega-3 index in the Spanish population over 60 years of age and to establish w…
