| Resumen en inglés | OBJECTIVE: The present study aimed at evaluating the effects of peanut, safflower and olive oils on the lipid profile, body composition and satiety of eutrophic, normolipidemic subjects. METHODS: Thirty-two 18 to 50 year-old subjects were recruited and randomly divided into four groups, each with 4 men and 4 women. One group received no treatment and the others received a milk shake for their breakfast, containing an amount of one of the oils (peanut, safflower or olive) equivalent to 30% of their basal energy metabolism, for a period of 8 weeks. The levels of total blood cholesterol and fractions, triacylglycerols, body weight, body composition, basal metabolic rate, dietary induced thermogenesis, satiety and food intake were evaluated on the basal, 4th and 8th weeks. RESULTS: No significant difference was observed in the lipid profile or satiety, but the safflower oil group showed lower levels of blood lipids. Oil intake, irrespective of its composition, led to an increase in body weight, and olive oil consumption increased the hip circumference. CONCLUSION: Contrary to reports in the literature, the addition of oils to the diet increased body fat deposition, and had no effect on blood lipid profile or satiety. The use of oil to substitute other energetic nutrients of the diet should be investigated in future studies, with a larger number of volunteers and a longer period of intervention |
