Two commonly talked about types of blood cholesterol include LDL (low-density lipoprotein) cholesterol and HDL (high-density lipoprotein) cholesterol. LDL cholesterol is considered ‘bad’ because it is associated with an increased risk of coronary heart disease, whereas HDL cholesterol is considered ‘good’ because it is thought to help reduce the risk of heart disease.

As cholesterol and saturated fat often occur together in the same foods, there has been some confusion in the past over which is responsible for raising blood cholesterol levels.
