Abstract: | 1.The effects of saturated fat and cholesterol on lipoprotein fluidity were tested in New Zealand white rabbits fed diets containing corn oil (CO) or cocoa butter (CB) with and without added 0.2% cholesterol. 2. Saturated fats had little effect on fluidity in any lipoprotein fraction. 3. Cholesterol feeding dramatically reduced fluidity in VLDL and LDL, but minimal change was noted in HDL. 4. Cholesterol-fed rabbits were hypercholesteroloemic throughout the 10-month study. 5. The rabbits became adapted to cholesterol feeding as VLDL became more fluid with time. |
