The effects on body composition and cardiovascular risk of functional meat products, within a balanced diet, were investigated in a randomized, double-blind, 10-week nutritional intervention. Fifty-four adults were distributed in three groups, consuming 600¿g/week of a reference meat product (RP), optimized nutritional product-1 (ONP-1), lower in fat, or ONP-2, n-3 PUFA enriched. Measures were performed at baseline and the endpoint. All groups lost fat mass, being subjects on the ONP-2 group those with more fat loss (p¿=¿0.042) compared to the other groups. Correlation analyses evidenced significant associations between alpha-linolenic acid (ALA) intake and plasma levels (p¿=¿0.001), as well as between plasma levels and fat mass changes (p¿=¿0.03). The inclusion of optimized meat products, with n-3 PUFA (Polyunsaturated fatty acids) and an improved nutritional profile may be a healthy strategy, as a functional food, within an isocalorically controlled diet. ALA consumption may play a role in body composition changes.
