Influence of avocado (Persea americana) pulp consumption on lipid metabolism in normolipidemic and diet induced hyperlipidemic mice . Dyslipidemia is a risk factor for developing cardiovascular disease, a major cause of deaths worldwide. The aim of this work is to study the effect of avocado (Persea americana), on lipid metabolism on normolipidemic and hyperlipidemic mice induced with high fat diet. Four groups of animals receiving standard diet (DE), standard and avocado diet (DEa), high fat diet (DH) and high fat and avocado diet (DHA) were used. All animals were observed for a period of 28 days. Blood sample was obtained at the end of experimentation period by cardiac puncture on anesthetized animals, and the levels of Cholesterol, triglycerides and col-HDL were de- termined and c-LDL, VLDL and atherogenic and coronary risk factors were calculated. DH group showed levels of TC, TG, c-LDL and VLDL significantly higher (p<0,001) than the values achieved in DHa group. DHa and DEa plasmatic values of TC, TG, c-LDL and VLDL were significantly reduced (p <0.001) compared to DH group. DEa and DHA groups differed significantly (p <0.005) in the level of CT, the latter has lower values, the other quantified parameters showed no significant differences. There were no significant differences for c-HDL values in any group. Hyperlipidemia induction with a model of high fat diet produced significantly increasing values of TC, TG, c-LDL and VLDL, besides of increasing the atherogenic risk. The benefit of avocado pulp consists in reduction of TC, TG, c-LDL, VLDL and the index of atherogenic risk.
