Plant Sterols May Help Lower Cholesterol

Heart-Healthy Benefits Seen in Diabetic Patients

WebMD Health News

June 17, 2005 -- Looking to lower your "bad" LDL cholesterol? Plant chemicals called sterols might help, say Canadian researchers in The American Journal of Clinical Nutrition.

Plant sterols resemble cholesterol but have been shown to block cholesterol's absorption and lower blood cholesterol beyond diet. They are minimally absorbed by the intestines, write McGill University's Peter J.H. Jones and colleagues.

Jones added a plant sterol mixture to margarine for the study. The sterol mix came from Forbes Medi-Tech Inc. Jones is a consultant for that company, says the journal.

Plant sterols are already on the market in various products, including cholesterol-lowering margarines such as Take Control and Benecol.

About Cholesterol

Cholesterol is a waxy, fat-like substance found in the body. The body makes and uses it, and cholesterol is also found in many animal-based foods. Excess cholesterol settles in the walls of blood vessels, including those of the heart, which can reduce blood flow and lead to heart disease.

The CDC estimates that 105 million Americans have cholesterol levels that are above desirable levels, which puts them at risk for heart disease. Desirable or optimal levels for people with or without heart disease are as follows, says the CDC:

  • Total cholesterol: Less than 200 milligrams per deciliter
  • LDL ("bad") cholesterol: Less than 100 milligrams per deciliter
  • HDL ("good") cholesterol: 40 milligrams per deciliter or higher
  • Triglycerides: Less than 150 milligrams per deciliter

Sterol Study

Jones' study was small, with 29 participants. All had high cholesterol, and 14 also had type 2 diabetes and were slightly overweight. Participants were 40-80 years old, averaging in their mid-50s. None exercised.

At the study's start blood cholesterol levels were measured. Next, the group was put on a low-fat diet. Everyone had to eat breakfast at the lab; lunches and dinners were taken home.

The lab-based breakfasts were important. They included toast with margarine containing a secret ingredient. The researchers added a plant sterol or a placebo powder (cornstarch) to the margarine. For 21 days, participants got one or the other spread on their morning toast.

Doable in the Real World?

The plan didn't totally mirror real life. For one thing, the participants didn't have to cook or select their meals. They also didn't have to worry about portion size, since the food was provided for them.

Plus, alcohol and coffee were banned. So were snacks, except for decaf, calorie-free sodas, and herbal teas made by McGill's kitchen staff.

Calories were adjusted, when needed, to keep everyone at their starting weight. Sterols in commercial products may or may not match the amounts used in the study.

Congratulations! Your total cholesterol level is in the Desirable range, and your level of "bad" LDL cholesterol is optimal.

Congratulations! Your total cholesterol level is in the Desirable range, and your level of "bad" LDL cholesterol is near optimal.

Your total cholesterol level is in the Desirable range, but your level of "bad" LDL cholesterol is borderline high. If your LDL goes higher, your total cholesterol level could become Borderline High. Consider reducing the amount of foods you eat with saturated fats and increasing physical activity. If you get more exercise, your level of "good" HDL cholesterol may increase, which could also help to keep your levels of LDL and total cholesterol in check.

Your total cholesterol level is in the Desirable range, but your level of "bad" LDL cholesterol is High. This may mean that your level of high-density lipoprotein (HDL), or "good" cholesterol, is too low. It is best to have a high level of "good" HDL and a low level of "bad" LDL. The HDL helps keep your LDL level in check. Ask your doctor for your HDL level. If your HDL is low, increasing your physical activity can increase it, which may help reduce your LDL level.

Your total cholesterol level is in the Desirable range, but your level of "bad" LDL cholesterol is Very High. This may mean that your level of high-density lipoprotein (HDL), or "good" cholesterol, is too low. It is best to have a high level of "good" HDL and a low level of "bad" LDL because the HDL helps keep your LDL level in check. Ask your doctor for your HDL level. If your HDL is low, increasing your physical activity can increase it, which may help reduce your LDL level.

Your total cholesterol level is Borderline High, but fortunately your level of "bad" LDL cholesterol is optimal. This could mean you have a high level of high-density lipoprotein, or "good" HDL cholesterol, which protects against heart disease. Or you could have other non-measured increases in LDL-like particles that can increase heart disease. Your LDL level also could be optimal if you are taking a statin medication. Please check with your doctor to get your complete lipid profile and see if you may need additional treatment. In the meantime, find more information on WebMD's Cholesterol Health Center.

Your total cholesterol is High, but your level of "bad" LDL cholesterol is optimal. This could mean you have a high level of high-density lipoprotein, or "good" HDL cholesterol, which protects against heart disease.
