Foods fortified with plant sterols or stanols

Manufacturers now fortify certain foods with substances found in plants. Called plant sterols or stanols, these substances are very similar in structure to cholesterol. This helps them block the absorption of cholesterol in the intestines.

Margarines and orange juice that have been fortified with plant sterols can help reduce LDL cholesterol by more than 10 percent. The amount of daily plant sterols needed for results is at least 2 grams.

These foods don't appear to affect levels of triglycerides or of "good" high-density lipoprotein (HDL) cholesterol. Nor do they interfere with the absorption of the fat-soluble vitamins — vitamins A, D, E and K.

However, the American Heart Association recommends foods fortified with plant sterols only for people who actually have high levels of LDL cholesterol.

Cut fats first

The first step for a heart-healthy diet is to reduce your intake of cholesterol and fats, especially saturated fats. But if that's not enough to reduce your test numbers to acceptable levels, you may want to try eating more soluble fiber, walnuts and fatty fish. The next step would be the addition of foods fortified with plant sterols.

Eating a combination of these cholesterol-lowering foods increases the benefit. But dietary changes alone are not always enough for everyone. If your cholesterol is still high after you've amended your diet and started an exercise program, your doctor may suggest cholesterol-lowering medications.
