Phytosterine: Phytosterols (also called plant sterols) are a group of steroid alcohols, phytochemicals naturally occurring in plants.

Die hydrierten Formen (5a-Hydrierung) der jeweiligen Phytosterine werden als Phytostanole bezeichnet. Die Phytosterine kommen in den Pflanzen frei, in Ester- oder in Glycosid-Form sowie im unverseifbaren Anteil von pflanzlichen Fetten und Ölen vor. Die häufigsten pflanzlichen Sterine sind Stigmasterin, ß-Sitosterin und Campesterin.[1] Phytosterine fungieren als strukturelle Komponente in der Zellmembran von Pflanzen, analog dem Cholesterin in der Zellmembran von Tieren … (full long text).

Phytosterin (Phytosterol) and phytostanolhaltige food are suitable for the reduction of the Cholesterinspiegels. The admission should 3 g of Sterine per day, according to 20 – since an increase of the dose does not cause further reduction of the Cholesterinspiegels ,  in addition, should be to 30 g margarine, not to exceed, not under a gram. The admission of Phytosterinen in the normal food is not sufficient for the lowering of the Cholesterins. A lowering of the Cholesterins over approx. 10% can be expected.
