Nutritional fat or oil-based compositions for increasing HDL cholesterol, decreasing total cholesterol (TC), LDL cholesterol and decreasing the LDL/HDL cholesterol ratio in human plasma are described. The compositions can advantageously include at least 10% of myristic acid and/or lauric acid in which at least 3% of said fatty acid composition is myristic acid and at least 3% is lauric acid; in some cases at least 1% by weight myristic acid and/or lauric acid is esterified at the sn-2 position in triglyceride molecules. The compositions also include between 5% and 40% by weight linoleic acid, and typically further include at least 10% by weight monounsaturated fatty acids and between 15% and 55% by weight total saturated fatty acids. The sum of weight percentages for saturated, monounsaturated and polyunsaturated fatty acids equals 100%. In desirable cases, the composition is substantially cholesterol-free. Also described are fat compositions and diets which are adapted to limit increases in blood triglycerides, total cholesterol, LDL, and VLDL, even in the presence of dietary cholesterol. |
