Relation between dietary fat composition and lipid metabolism in the rat.

Three fats were used in a synthetic dietary formula containing 20% of its composition as fat from either lard, peanut oil or maize oil. Twelve groups of rats were included in this study, six groups served as controls; 3 from each sex. Control groups received the same dietary formula except fat content was 10%. Saturated dietary fats in male rats seems to be atherogenic while in females, increasing dietary fat to 20% gave atherogenic picture.
