Do Plant Sterols Lower Cholesterol?
Introduction
Many people suffer from high cholesterol levels, which can lead to various health problems. While medication is often prescribed to lower cholesterol, there are also natural remedies that can be effective, such as including plant sterols in your diet. But what are plant sterols, and do they really lower cholesterol? Let's dive into the science and find out.
What are Plant Sterols?
Plant sterols, also known as phytosterols, are naturally occurring compounds found in plants such as fruits, vegetables, nuts, and grains. They are structurally similar to cholesterol and can lower cholesterol levels by blocking the absorption of cholesterol in the intestines.
How Do Plant Sterols Work?
Plant sterols work by competing with cholesterol for absorption in the small intestine. When plant sterols are present, they inhibit the absorption of dietary cholesterol, leading to a decrease in overall cholesterol levels. Plant sterols can also reduce the production of cholesterol in the liver, further lowering total cholesterol levels.
Research on Plant Sterols and Cholesterol
Numerous studies have investigated the effect of plant sterols on blood cholesterol levels. One meta-analysis published in the Cochrane Library analyzed 124 randomized controlled trials and found that plant sterols reduced LDL cholesterol levels by an average of 10%. Another study published in the Journal of the American Medical Association found that daily consumption of plant sterols decreased LDL cholesterol levels by 6.5%.
How to Include Plant Sterols in Your Diet
The most common way to consume plant sterols is through fortified foods such as margarine, orange juice, and yogurt. These products are enriched with plant sterols and can be easily incorporated into your daily diet. Plant sterol supplements are also available for those who prefer a more concentrated form of consumption.
Precautions
Though plant sterols are generally considered safe, consuming too much can lead to unwanted effects such as gastrointestinal disturbances, such as stomach cramps and bloating. Additionally, plant sterols supplements should not be used as a substitute for prescription medication for high cholesterol levels.
Conclusion
Overall, scientific evidence suggests that plant sterols can effectively lower cholesterol levels. By consuming plant sterols through fortified foods or supplements, you may be able to reduce your need for cholesterol-lowering medications or prevent high cholesterol levels in the first place. However, as with any dietary supplement, it is important to discuss your use of plant sterols with your healthcare provider to ensure they are safe and appropriate for your individual needs.
