It is the case of Blighia sapida aril oil (BsO). Therefore, the purpose of this study was to understand the effects of BsO consumption on rats in comparison with refined palm oil (PO) or olive oil (OO) consumption. Eighteen young rats divided into 3 groups were fed, ad libitum with diets prepared with BsO or PO or OO, during 28 days. At the end of the experimentation, blood sample and urine were collected and analyzed. Animals were sacrificed, viscera organs were removed, weighed and were processed for histopathological studies. Thighbones and shinbones were removed and their length, thickness and volume were measured. Ash, calcium and phosphorus of bone collected were measured after incineration. We observed no significant variation of metabolism parameters, urine parameters, viscera weight and hematological parameters between the groups of rats. A non-significant increase of bone ashes weight was due to PO consumption than BsO consumption. A significant increase of bone ashes weight was observed in case of OO consumption than BsO consumption. Atherogenicity index reveal that BsO consumption increases slightly this index than PO and outstandingly than OO. BsO has some nutritional values and are not induced toxicity so that it is interesting for human diet.
