A low-fat high-carbohydrate diet supplemented with long-chain n-3 PUFAreduces the risk of the metabolic syndrome
Résumé
Objective: Dietary changes are major factor in determining cardiovascular risk. We assessed the effects of isoenergetic diets with different fat quantity and quality on the incidence and regression of the metabolic syndrome (MetS) from the LIPGENE project.
Methods and design: Clinical intervention study: the patients (n = 337) were randomly assigned to one of four diets for 12 weeks each: two high fat diets, one rich in saturated fat (HSFA) and the other rich in monounsaturated fat (HMUFA), and two low fat diets, one high in complex carbohydrates (LFHCC) supplemented with 1.24 g/day of long-chain n-3 polyunsaturated fatty acids (LFHCC n-3) and the other LFHCC diet with placebo (LFHCC). Measurements: the effects on MetS risk criteria were recorded before and after the intervention period.
Conclusions: The consumption of a low-fat high-carbohydrate supplemented with n-3 diet reduced the risk of MetS as compared with isoenergetic high-fat (HSFA and HMUFA) and LFHCC diets. (C) 2011 Elsevier Ireland Ltd. All rights reserved.
