Phytosterols is also referred to as plant sterol and stanol esters. Consuming 2-3g daily, can naturally lower the “bad cholesterol”, known as Low-Density Lipoprotein (LDL) Cholesterol by approximately 10% over a period of three weeks. This does not affect the “good cholesterol”, known as High-Density Lipoprotein (HDL) Cholesterol or triglycerides. High amounts of LDL Cholesterol in the blood have been linked to coronary heart disease.
Consuming more than 2-3g, will not do harm but will not provide additional benefits in LDL reduction.
Plant sterols are found naturally in nuts, seeds, grain products, fruit, vegetables and even vegetable oils. Although we consume plant sterols daily in our diet, the amount consumed is typically too low to have an effect in lowering LDL cholesterol.
