Cholesterol vehicle in experimental atherosclerosis. Part 15. Randomized butter and randomized lard.

Randomized lard and butter oil were conpared with native lard and butter oil for their effects on cholesterol-induced atherosclerosis in rabbits. In each experiment there was also a group fed corn oil. The diets contained 2% cholesterol and 6% fat and were fed for eight weeks. Randomization of either butter or lard had virtually no effect as regards their atherogenic potential when fed as part of a diet containing 2% cholesterol. The corn oil-containing diet was less atherogenic than any of the other fats.
