- W1949668510 abstract "Introduction and aims: Taking into account the sanitary importance of the contribution of omega-3 and omega-6 fatty acids and given the scarcity of studies on the subject in Spanish collectives, the aims of the present study were to determine the intake of these fatty acids, their adequacy to the established nutritional goals and food sources in a representative sample of the Spanish population. Methods: A group of 1,068 adults (521 men and 547 women) with ages ranging from 17 and 60 years were studied. The subjects were selected from ten Spanish provinces to constitute a representative sample of the nationwide population. The intakes of polyunsaturated fatty acids (PUFA), omega-3 fatty acids, α-linolenic acid (ALA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), omega-6 fatty acids, linoleic acid (LA) and arachidonic acid, expressed in g/day and percentage of the total energy intake, were determined by using a food record for 3 consecutive days, including a Sunday. Personal, anthropometric and sanitary data of individuals were also studied. Results and Discussion: The intake of total fat and saturated fat was higher than the established as advisable in 89.2% and 93.3% of the studied subjects, respectively. The opposite was observed for the intake of PUFA, where an insufficient contribution was most frequent (79.2% of the subjects have an intake less than the 6% of the energy). The contribution of omega-3 fatty acids (1.85±0.82 g/day) is particularly low, and provides less than 1% of the energy in 85.3% of subjects. Specifically the ALA (1.40±0.55 g/day) did not exceed the 0.5% of energy in 53.7% of the cases, and the EPA + DHA (0.55±0.58 g/day) did not exceed 0.5 g/day in 64.6%. On the other hand, the contribution of omega-6 was more appropriate (10.95 ± 3.79 g/day), specifically for LA intake (10.77 ± 3.76 g/day), representing less than 3% of the energy in the 25.5% of subjects. The main food sources for omega-3 were fish, followed by meat, dairy and fats/oils, whereas for omega-6 were fats/oils, meat and cereals. Taking into account that the low consumption of omega-3 fatty acids is noteworthy in the studied group, especially for EPA + DHA, the influence of the fish Resumen Introduccion y Objetivos: Teniendo en cuenta la importancia sanitaria del aporte de acidos grasos omega-3 y omega-6, y ante la escasez de estudios sobre el tema en colectivos espanoles, se plantea la conveniencia de conocer la ingesta de estos acidos grasos, su adecuacion a los objetivos nutricionales marcados y sus fuentes alimentarias en una muestra representativa de la poblacion espanola. Metodos: Se ha estudiado un colectivo de 1068 adultos (521 varones y 547 mujeres) de 17 a 60 anos, seleccionados en diez provincias espanolas, que constituyen una muestra representativa de la poblacion, a nivel nacional. Se determino la ingesta de acidos grasos poliinsaturados (AGP), acidos grasos omega-3, α-linolenico (ALA), acido eicosapentaenoico (EPA) y docosahexaenoico (DHA), acidos grasos omega-6, acido linoleico (LA) y araquidonico, en g/dia y en porcentaje de la energia, utilizando un “Registro del consumo de alimentos” durante 3 dias consecutivos, inclu" @default.
