Introduction:
Sterols are the most important trace element in fat.
Cholesterol is a type of sterol, the main sterol in animal’s fat. There are two types of cholesterol in human blood: high-density lipoprotein (HDL)cholesterol and low-density lipoprotein (LDL) cholesterol. Among them, excessive accumulation of LDL cholesterol in the serum can lead to blockage of arteries and heart disease.
Acceding to the EFSA
Moderate intake of plant sterol can lower blood cholesterol level and reduce the risk of coronary heart disease.
The U.S. Food and Drug Administration (FDA) allows food labels to be noted:
Plant sterol esters or plant esters reduce the risk of coronary heart disease.
Health Canada also allows it to be shown on food labels that plant sterol can help reduce cholesterol level.
Although plant sterols have good stability, they can cause oxidation after high temperatures or prolonged exposure to the air. Eating oxidizing phytosterols can lead to inflammation, unstable hormone levels, carcinogenicity and other health problems.
