Different Lipid's Sources: Influence on Serum Fatty Acid Profile, in an Experimental Model

It is widely accepted and recognized, the importance of diet in maintaining health. Diet lipid profile is important to prevent chronic diseases and improve the quality of life of individuals. The objective of this report is to analyze the effect of different sources of dietary lipids with standard and high concentration, on fatty acid profile of growing rats. Experimental diets contained 15 or 40% kcal of fat, provided by butter (B), olive oil (O), sunflower oil high oleic acid (HO) and sunflower oil (S). Control diet (C) was norm caloric, with 15%kcal of fat provided by soy oil. All diets were complete in the others nutrients and were administered for 40 days. Daily intake was similar in all groups. The administration of these diets provoked changes in serum fatty acid profile in response to the differences sources of dietary lipids used, only some changes observed in G group were in response to the high fat percentage.
