Efecto del consumo de dietas con avena y caraotas negras sobre el perfil lipídico en un modelo experimental en rata

the consumption of foods rich in soluble and insoluble dietary fiber (df) favorably affects the serum lipid profile by lowering total cholesterol, ldl-cholesterol and triglycerides (tg). the objective of this work was to compare the effect of consumption of diets with oats (avena sativa) and black beans (pha seo lus vulgaris) on the lipid profile of rats. fifteen male rats, spra gue dawley strain were fed ad libitum for 18 days, with three different diets: a control, one containing black beans (15% w / w) and another with oats (15% w / w). the serum total cholesterol concentration decreased 50.56% in the group fed with oats and 40.52% in the group fed with beans. also a de crease of ldl-cholesterol 49.21% in the group fed with oats and 42.93% in the group fed with beans was observed. there was 52.47% reduction of hdlcho lesterol in the group fed with oats and 31.29% for the group fed with beans, this is not a be neficial reduction. the serum tg concentration was significantly lower, 50.20% for the group fed with oats and 51.8% for the group fed with beans. the decrease of these lipids due to diet containing oats or beans, was significantly different from control but not between them. consideration of these results for human health is very important, particularly in reducing the prevalence of cardiovascular disease. the fd effect on hdl-cholesterol levels, are until now contradictory
