Did you know plants can improve your cholesterol? Sterols and stanols, which are components of plant membranes, structurally resemble cholesterol. In fact, their structures are so similar to cholesterol that our bodies can’t distinguish the difference. However, plant sterols and stanols are either not absorbed or minimally absorbed in the body. When they are present in sufficient quantities they compete with cholesterol in the digestive tract to form “mixed micelles”, which are particles needed to absorb cholesterol. Therefore, sterols and stanols decrease the amount of cholesterol absorbed in the body and can help to improve cholesterol levels.
So how much do you need? It is recommended that you consume 2-3 gm of plant sterols/ stanols per day in order to lower LDL (the “bad” cholesterol) by 10-15%. HDL (the “good” cholesterol) levels are unchanged by these compounds. It is often recommended to consume this level in two servings eaten at different times of the day (i.e. breakfast and dinner) to get maximum benefits.
Plant sterols/stanols are found naturally in many fruits, vegetables, vegetable oils, nuts, seeds, cereals and legumes. However, they are only present in small quantities. Therefore, there have been many foods that have been fortified to help achieve the desired level. See the chart below for a list of some popular products that contain plant sterols and stanols.
One disadvantage to these products is that the calories can add up and lead to weight gain if you don’t compensate by lowering calories in another area in the diet. Any weight gain could take away from the cholesterol lowering benefits these products provide. These products are also not meant to replace cholesterol lowering medications, but they are just one component of a healthy diet that may aid in improved cholesterol levels.
