Phytosterols – Plant-Based Cholesterol-Lowering Compounds
Phytosterols are natural plant compounds that lower LDL cholesterol. Found in nuts and oils, they support heart health and lipid balance.
Things worth knowing about "Phytosterols"
Phytosterols are plant-derived compounds that are structurally similar to cholesterol.
Naturally found in nuts, seeds, vegetable oils, and whole grains, Phytosterols are best known for their ability to reduce LDL cholesterol levels without affecting beneficial HDL cholesterol.
Their mechanism is based on competition in the gut: phytosterols displace cholesterol from micelles, leading to less cholesterol being absorbed. Clinical trials show that a daily intake of 1.5–3 g phytosterols can lower LDL cholesterol by 7–12 %, making them particularly useful for individuals with mild hypercholesterolemia.
In Europe and elsewhere, foods such as margarine, yogurt, and milk drinks may be fortified with phytosterols. While generally considered safe, high intakes may not be suitable for people with sitosterolemia, a rare metabolic disorder affecting fat absorption.
