In the present study. C57BU6N mice, an atherosclerosis diet-inducible
strain. were raised on atherogenic diets containing 15% of either butter oil or olive oil
for 3 months. Compared to olive oil diet. butter oil diet enhanced mice growth.
increased serum HDL-cholesterol concentration, reduced liver cholesterol content and
also reduced the atherogenic index. Both experimental diets did not develop any
atherosclerotic lesions in the aortic valve. The attained results revealed that
consumption of butter oil altered blood lipid profiles in such a manner as not to elevate
the risk factors for cardiovascular diseases.
