Introduction: The benefits of polyunsaturated omega 3 (n-3) on lipid metabolism and cardiovascular health fatty acids are widely accepted. However, the impact of n-3 in body composition, glucose homeostasis and consequent modification of cardiovascular risk has not been the focus of the primary outcomes of most clinical trials. Aim: To evaluate the impact of n-3 supplementation on body composition, glycemic control and the level of cardiovascular risk in adults. Methods: From a subsample of CARDIONUTRI study were selected (clinical, randomized, controlled, double blind study with follow-up of 2 months) 86 patients (group n-6, 3g of sunflower oil/d) and 88 individuals (n-3 group, 3g fish oil/d - 60 per cent EPA/DHA ). The effect of the interventions was monitored at baseline and T = 8 (eight weeks). In these periods were collected demographic information, clinical, physical activity, diet, anthropometric and body composition. After 12h fasting, blood samples were collected and, from plasma/serum, were evaluated glucose, insulin, total cholesterol, cholesterol associated with LDL and HDL, triacylglycerol, apolipoprotein AI and B using standard methods. The level of cardiovascular risk of individuals was estimated by the Framingham Risk Score (FRS). The results of the effect of the time of the intervention and the interactions between monitored parameters and outcomes were analyzed using the SPSS 20.0 program and the level of significance of p < 0.05. Results: The majority of individuals included were female and white, with no difference between groups. The most prevalent diseases in both groups were hypertension, diabetes mellitus and dyslipidemia. No change was observed in glucose and fasting insulin, HOMA-IR and HOMA 2- per cent S, with supplementation with n-3, except in patients with intermediate cardiovascular risk, according to the FRS. Regarding the anthropometric and body composition parameters, the n-3 group showed a reduction in the percentage of fat mass among females over time and intervention, as was also observed that reduction among individuals at high cardiovascular risk. There was no variation in the distribution of the ERF, despite the improvement of its components (total cholesterol and HDL-C). Conclusions: Supplementation with n-3 promoted reduction of insulin and HOMA-IR in subjects with intermediate FRS. It noted beneficial effect in reducing the percentage of body fat among women and individuals with high FRS, as well as decreased total cholesterol and increased HDL-C. (AU) | |
