ABSTRACT

Estratégias têm sido utilizadas para a prevenção de doenças cardiovasculares e aumento de peso. Sendo assim, muito tem sido especulado sobre alimentos funcionais e seus efeitos benéficos para a saúde humana e, em especial do Ácido Linoleico Conjugado (CLA). O objetivo foi avaliar os efeitos da dieta hiperlipídica e do CLA sobre os lipídios séricos, peso e composição corporal de camundongos Apolipoproteina E(-/-) (Apo E) exercitados. Camundongos knockout para Apo E foram alocados em quatro grupos/dieta: Normal (n=5), Hiperlipídica (n=6), Normal+CLA (n=5) e Hiperlipídica+CLA (n=6). Todos os grupos foram submetidos a um protocolo de corrida em esteira. Determinou-se o colesterol total, LDL-c e HDL-c no sangue, o peso e a composição corporal. Utilizou-se ANOVA e Tukey ao nível de significância de 5%. A dieta hiperlipídica elevou o colesterol total (Hiperlipídica=920,2±392,3 e Normal=382,3±207,9), LDL-c (Hiperlipídica=893,9±402,9 e Normal=339,9±204,8) e o peso corporal (Hiperlipídica=25,83±1,90 e Normal=339,9±204,8). O CLA reduziu a gordura (CLA=4,24±1,82 e Sem CLA=6,28±2,77) e elevou a proteína (CLA=23,02±1,04 e Sem CLA=21,45±1,04) na carcaça. Concluiu-se que a dieta hiperlipídica aumenta colesterol total e LDL-c e, o consumo de CLA diminui o gordura e aumenta a proteína na carcaça de camundongos Apo E(-/-) exercitados.


Strategies have been used for prevention of cardiovascular disease and weight gain. So much has been talked about functional foods and their beneficial effects on human health and, in particular conjugated linoleic acid. Evaluate the effects of high-fat diet and CLA on serum lipids, weight and body composition in Apolipoprotein E (-/-) mice (Apo E) exercised. Knockout mice ApoE were divided into four groups/diet: Normal (n=5), High-fat (n = 6), Normal+CLA (n=5) and High-fat+CLA (n=6). All groups underwent a protocol of treadmill running. Total cholesterol, LDL-c and HDL-c in the serum, weight and body composition were measured ANOVA followed by Tukey test were used (P<0.05). The high-fat diet elevated total cholesterol (High-fat=920,2± 392,3 and Normal=382,3±207,9), LDL-c (High fat=893,9±402,9 and Normal=339,9±204,8) and body weight (High-fat=25,83±1,90 and Normal= 339,9±204,8). The CLA reduced fat (CLA=4,24±1,82 and Without CLA=6,28±2,77) and increased the protein (CLA=23,02±1,04 and Without CLA=21,45±1,04) in the carcass. We conclude that the High-fat diet increases total cholesterol and LDL-C, and the consumption of the CLA reduces fat and increases the protein in the body composition of exercised ApoE(-/-) mice.
