Believe it or not, orange peel (citrus peels in general) is good for lowering bad or LDL cholesterol by as much as 32 to 40 percent. Orange and citrus peels supposedly contain polymethoxylated flavones (PMEs) which are use in expensive prescription medication for high cholesterol. An international study reported that supplements made from orange and tangerine peels may even be better than popular cholesterol-lowering prescription drugs, because they have none of the potentially debilitating side effects like liver disease and muscle weakness, common with cholesterol-lowering prescription medication. Unfortunately, it would take more than nibbling on one orange peel to significantly lower cholesterol. Indeed, it would take the equivalent of 20 or more cups of orange juice each day to achieve a recognizable effect. As such, it would be best to take supplements made from citrus peels - which are more potent - instead.
