Phytosterols are natural plant compounds that have attracted much attention in the medical field in recent years. Multiple studies have shown that phytosterols can lower cholesterol levels and protect cardiovascular health. This article will provide an in-depth analysis and explanation of plant sterols from a medical professional perspective.
Mechanism of Action of Phytosterols Phytosterols reduce cholesterol levels by inhibiting the body’s absorption of cholesterol.
Cholesterol is a lipid substance. Excess cholesterol can be deposited in the blood and form the basis of atherosclerosis. Phytosterols competitively bind to cholesterol and occupy absorption sites in intestinal epithelial cells, thereby reducing the amount of cholesterol absorbed and lowering cholesterol levels.
Clinical Research Evidence for Phytosterols Many clinical studies have confirmed the significant effect of phytosterols on lowering cholesterol. A meta-analysis study published in The Lancet showed that using foods or dietary supplements containing plant sterols can reduce total cholesterol levels by about 10%. Additionally, several other studies have found that long-term application of phytosterols has a positive effect on reducing LDL cholesterol (bad cholesterol) and the ratio of total cholesterol to HDL cholesterol (good cholesterol).
Effects of Phytosterols on Cardiovascular Health Lowering cholesterol levels is one of the key strategies for preventing cardiovascular disease. Research shows that phytosterol intake may reduce the risk of cardiovascular disease. Cardiovascular disease is a disease caused by arteriosclerosis, and plant sterols, as a method of lowering cholesterol, can reduce the deposition of cholesterol on the arterial wall, thereby reducing the risk of atherosclerosis and protecting cardiovascular health.
Safety and Recommended Dosage of Phytosterols According to the recommendations of the International Council for Food Information (Codex), the daily intake of plant sterols for adults should be controlled within 2 grams. In addition, phytosterol intake should be obtained through food and excessive use of dietary supplements should be avoided. It is important to note that pregnant women, breastfeeding women, and patients with gallbladder disease should consult a physician before using phytosterol products.
As a natural substance, phytosterols have an important role in lowering cholesterol and protecting cardiovascular health. By inhibiting cholesterol absorption, phytosterols can effectively lower cholesterol levels and reduce the risk of cardiovascular disease.
