Plant sterols > for food, dietary supplements and beverages

Phytosterols are steroid compounds, which appear in the membrane of plants. The chemical structure is similar to Cholesterin, but has an additional chain and a double bond in the structure. Naturally Phytosterols are found in vegetables, fruits, legumes, nuts and grains. The best known types are ß-sitosterol, campesterol, stigmasterol, brassicasterol. Sterols occur also in an esterified form with natural plant oils. This form makes it easier to handle the product for food or encapsulated applications.
The health effect of Phytosterols is based on the ability to reduce the risk for cardiovascular diseases. High cholesterol levels are the main contribution factor to the development of coronary heart diseases. Due to an increased LDL-cholesterin level the risk for atherosclerosis rises. The cholesterol deposits on the vessel wall narrow the vessel so that the blood flow is disturbed. Consequently the risk for myocardial infarction/coronary heart diseases and stroke is increased.
The probable mechanisms are visible at the intestinal level, as the absorption of cholesterol in the gut is reduced. Another effect is the inhibition or competition with the enzyme pancreatic cholesteryl esterase.
The two effects result in a lower adsorption of cholesterol in the corp.
1-3 g/d of plant sterols/plant sterol esters results in ~7-12% LDL cholesterol reduction. With the daily human diet we consume ~160 – 400 mg/d out of natural components.
