32. Cholesterol-Lowering Phytosterols
Phytosterols (plant sterol and stanol esters) are compounds found in small amounts in foods such as whole grains as well as in many vegetables, fruits, and vegetable oils. They decrease LDL cholesterol, mostly by interfering with the intestinal absorption of cholesterol. Some foods contain these nutrients called phytosterols, which are like plant versions of cholesterol. Studies have shown that they can lower blood cholesterol, which is why they’re often added to processed foods. That is why it is essential always to read the labels on your food. Try to avoid processed foods all together when and where you can.
They’re marketed as “cholesterol-lowering”, with a claim that they help prevent heart disease. That simply isn’t true. They might lower cholesterol, but research shows that phytosterols can increase the risk of heart disease and death. Foods containing the highest concentration of naturally occurring phytosterols include oils (wheat germ oil, rice bran oil, corn oil, canola oil), seeds (sesame seed, sunflower seed), nuts (pistachio, pine nut, almond), whole grains such as wheat germ, bran (rice bran, corn bran, wheat bran), flour (soy flour). It’s better to practice eating a balanced diet than consuming more foods that are marketed as “cholesterol-lowering”.
