The subject of using plant sterols and stanols as a natural substitute for ezetimibe (Zetia) was brought up in one of the comments. Plant sterols and stanols are both natural substances that work much like the prescription drug ezetimibe in that they block the absorption of dietary cholesterol in the intestine (as opposed to statins which stimulate LDL cholesterol removal in the liver).
Both sterols and stanols work equally well although not as powerfully as ezetimibe. Of the two, plant stanols are considered superior to sterols for two reasons. First, one study found that sterols can lose effectiveness over time and stanols do not. Second, stanols are not absorbed by the body so there is little danger of toxic effects due to long-term build-up.
Stanols also do not occur as frequently in nature and appear to be more expensive to produce. It is no co-incidence then, that stanol bearing products like Benecol are more expensive than other similar products which contain sterols. In fact, I do not know of another major brand that uses stanols over sterols but Benecol.
I love this stuff primarily because I have deprived myself of so many foods I used to enjoy and can now eat a tasty "fat" without having worry that it is killing me. I am practically giddy that I can eat a piece of toast or add something to dry popcorn that is actually good for me.
