Cholesterol is one of the major substances that cause heart attacks, high blood cholesterol levels, and weight problems. Despite its “bad guy image,” this waxy, fat-like substances made in the body by the person’s own liver serves a number of vital functions unknown to many.
Basically, there are two types of cholesterol: the Low-Density Lipoprotein (LDL) and the High-Density Lipoprotein (HDL). The former refers to the bad type of cholesterol that is known to clog the person’s blood vessels, thus, increasing the risk for a heart attack or a heart disease. Studies show that a diet that is high in saturated fat is a main dietary cause of a raised LDL cholesterol level. The latter, on the other hand, is the good type of cholesterol that helps clear LDL cholesterol out of the blood stream, thus, reducing the risk for any heart illness. Researches have shown that a diet rich in fruit and vegetables along with average levels of omega-3 from fish oil greatly helps raise HDL cholesterol levels.
