HEALTH BENEFITS: PLANT STEROL MASTER CLASS
Clinical studies indicate that, when consumed as part of a diet low in saturated
fat and cholesterol, plant sterols can help reduce the absorption of cholesterol
in the small intestine by up to 50%, which in turn can lower LDL blood cholesterol
by 5-14%.
Plant sterols, also known as phytosterols, are plant-based compounds that occur
naturally in fruit, vegetables, legumes, whole-grain products and most vegetable
oils, but usually at levels too low to effect LDL cholesterol. But plant
sterols can be added to other foods at beneficial levels that help lower blood cholesterol
and reduce risk of coronary heart disease.
These naturally-occurring substances are the plant’s cholesterol. Just as humans
have cholesterol, so do plants. If you were to look at plant sterols under a microscope,
they look very similar to human cholesterol. Thanks to this nearly identical structure,
plant sterols compete with cholesterol for access to receptors in the small intestines
known as micelles. Micelles help transport cholesterol through the intestine into
your blood stream. Over 140 clinical studies have shown that plant sterols can help
reduce LDL cholesterol levels by 5% - 14%.
While there are more and more heart healthy snacks and heart healthy foods available
today, those which have plant sterols (meeting specific FDA criteria) can sport
a statement on the package indicating they may help reduce the chances of heart
disease.
How much plant sterols does it take to do the job?
Experts recommend that to get the maximum cholesterol-lowering benefits, you should
consume between 1.5 to 3 grams of plant sterols per day. To begin to see any benefits
you need to consume a minimum of 0.8 grams per day. Most Americans get approximately
0.25 grams of plant sterols per day from the foods they consume. While it may be
difficult to get this amount naturally from heart healthy foods such as fruits and
vegetables, it is very achievable if you incorporate foods fortified with plant
sterols such as specific chips, breads, and margarines.
