Plant sterols identified as effective for reducing LDL cholesterol

Research indicates that plant sterols can help reduce LDL cholesterol levels by competing with cholesterol for absorption in the intestines. While these natural compounds are found in small amounts in fruits, vegetables, cereals, nuts, and vegetable oils, typical dietary intake is often insufficient for significant reduction.

Data from the Spanish Heart Foundation shows that nearly 60% of Spaniards possess two or more cardiovascular risk factors, including hypercholesterolemia. To achieve a reduction of up to 10% in LDL cholesterol within two to three weeks, a daily dose of approximately 1.6 grams is required. Achieving this amount through whole foods would necessitate consuming 1.5 kilograms of walnuts, 10 kilograms of bananas, or 4 kilograms of broccoli.

Furthermore, research from the Spanish National Research Council (CSIC) suggests that the specific type and combination of sterols, such as beta-sitosterol and beta-sitostanol, influence their effectiveness in interfering with intestinal cholesterol absorption.
