Stanol ester
From Wikipedia, the free encyclopedia
Stanol ester is a heterogeneous group of chemical compounds known to reduce the level of low-density lipoprotein (LDL) cholesterol in blood when ingested. The starting material is sterols from plants. These are first hydrogenated to give stanol which is then esterified with a mixture of fatty acids also derived from plants. Stanol esters are found naturally occurring in small quantities in fruits, vegetables, nuts, seeds, cereals, legumes, and vegetable oils.
Stanol ester is often added to rapeseed oil based margarine or other foods for its health benefits. Studies have indicated that consumption of about 2 grams per day provides a reduction in LDL cholesterol of about 10%. The compound itself passes through the gut without entering the blood stream or lymph. Its presence, however, reduces both the amount of cholesterol the body absorbs from food and the reabsorption of the cholesterol component of bile.
Stanol ester was developed by Ingvar Wester, a Finnish chemist. It is marketed by the Raisio Group with the trade name Benecol.
Sterol esters can also be used for the same purpose. These compounds have the same effect to LDL, but they are partially absorbed by the body.
