Saturated fatty acid (SFA) status and SFA intake exhibit different relations with serum total cholesterol and lipoprotein cholesterol: a mechanistic explanation centered around lifestyle-induced low-grade inflammation.

We investigated the relations between fatty acid status and serum total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein (HDL) cholesterol and total cholesterol/HDL cholesterol ratio in five Tanzanian ethnic groups and one Dutch group. Total cholesterol/HDL cholesterol ratio is a widely used coronary artery disease (CAD) risk factor. Fatty acid status was determined by measurement of fatty acids in serum cholesterol esters and erythrocytes.
