However, a fit and healthy individual, who consumes good food and exercises regularly, might have high levels of bad cholesterol. Therefore, one must try to maintain high levels of HDL cholesterol in their blood to lower the risk for heart disease and stroke. HDL cholesterol, also known as good cholesterol, absorbs cholesterol in the blood, and carries it back to the liver, following which the liver flushes the cholesterol from the body. LDL cholesterol, also known as bad cholesterol, makes up most of the body's cholesterol, and high levels of this cholesterol increases one's risk for heart disease and stroke. There are two types of lipoproteins, namely low-density lipoprotein (LDL) and high-density lipoprotein (HDL). The proteins on which cholesterol travels through the blood are called lipoproteins. Experts recommend that people consume as little dietary cholesterol as possible because the body already makes all the blood cholesterol it needs, according to the Centers for Disease Control and Prevention.
