Phytosterols

Phytosterols (also called plant sterols) are a group of steroids naturally occurring in plants. Phytosterols are similar in structure to cholesterol. Some of the most common phytosterols include beta-sitosterol, campesterol, and stigmasterol. Phytosterols have been shown to help lower LDL cholesterol levels.

Structure and Function[edit | edit source]

Phytosterols are structurally similar to cholesterol, which allows them to displace cholesterol from micelles and inhibit the absorption of cholesterol in the intestine. This can lead to a decrease in blood cholesterol levels. Phytosterols also have anti-inflammatory, anti-cancer, and anti-oxidative properties.

Sources of Phytosterols[edit | edit source]

Phytosterols are found in high amounts in certain vegetable oils, seeds, and nuts. They are also found in smaller amounts in fruits, vegetables, and cereals. Some food products are also fortified with phytosterols.

Health Benefits[edit | edit source]

Several studies have shown that phytosterols can help lower LDL cholesterol levels. They may also have potential benefits in the prevention and treatment of cancer, heart disease, and inflammation.

Side Effects and Risks[edit | edit source]

While phytosterols are generally considered safe, they can cause side effects in some people. These can include diarrhea, nausea, and indigestion. There is also some concern that high intakes of phytosterols could potentially interfere with the absorption of certain vitamins and minerals.
