    ABSTRACT: Healthy lifestyle practices play a key role in preventing and treating cardiovascular disease, where specific dietary approaches are a central strategy for optimal life quality. Dyslipidemia is a condition in which there is a desbalance in the serum lipid profile that can be produced by different factors including dietary habits. At this time, current dietary guidelines to reduce cardiovascular risk factors are mainly based in seafood as source of -3 fatty acids, including eicosapentaenoico acid (EPA, 20:5 -3) and docosahexaenoico acid (DHA, 22:6 -3), which are proposed to be the key nutrients responsible for the potential cardioprotective effects. These -3 fatty acids can be intake from fish, shellfish and/or fish oil supplements. Although fish provides -3 fatty acids, it also is an excellent source of other nutrients that may have synergistic effects for cardioprotection. The propose of this article is to review the updated evidence-based literature, from observational and clinical studies, regarding dietary approaches where -3 fatty acids perform a eminent role as component of diet for maximal cardiovascular risk reduction.

    ABSTRACT: The objective of this work was to compare by multivariate techniques three cultivars of peanut (Rojo, Rosado andAmericano Chico). Seed lipids were extracted with a chloroform-methanol mixture (2:1 v/v). For the chromatographyanalyses of fine layer with ionization detector in flame (TLC/FID), chromads SIII were used. The gas-liquidchromatography was used to determine the fatty acids composition. Percentage of total lipids, lipid composition, viz,triacylglycerol, diacylglycerol, phospholipids and fatty acids composition, viz, palmitic, araquídic, oleic, linoleic, linolenicand eicosenoic acids were determined. For the principal component analysis, the first component explained 64.3% of thevariation and the second one explained 35.7% (total 100.00 %), the peanut cultivars did not associate among them, id est,three individual groups were formed. In general, all traits had high values of loadings, excepting eicosenoic acid (C20_1)and behemic acid (C22_0). Cluster analysis indicated different results than principal component analysis. Both, UPGMAand Ward methods produced two groups, the first one formed by Americano Chico and the second group formed forcultivars Rojo and Rosado. In conclusion, cluster analysis should be used to study the relationships among total lipids, lipidcomposition and fatty acids in order to identifying similar groups for these characters for different peanut cultivars.
