Overview

Cholesterol is a waxy substance found only in foods of animal origin such as poultry, beef, fish, eggs, and dairy products. Cholesterol can be made from the liver, and thus is not needed in the diet for normal cellular processes. Cholesterol must be combined with fats and proteins to form lipoproteins before it can be transported through the body within the blood. The many different lipoproteins vary in size, function, and composition. One type is low-density lipoprotein (LDL). Commonly referred to as bad cholesterol, it comprises approximately two-thirds of the total circulating blood cholesterol. Because the LDL transports high levels of cholesterol through the bloodstream, it is associated with plaque deposits on the walls of the arteries, resulting in a higher risk for cardiovascular events. High-density lipoprotein (HDL) is referred to as the good cholesterol because it scavenges excess cholesterol from the blood and brings it back to the liver for excretion. Another class of lipoproteins, the very low-density-lipoproteins (VLDL), are responsible for carrying triglycerides through the bloodstream. The TLC diet is a set of dietary guidelines for medical professionals to prescribe when using medical nutrition therapy as the first treatment for patients who have heart disease or are at high risk for developing the disease due to their elevated levels of total cholesterol and low-density lipoprotein cholesterol (LDL), and possibly a low amount of high-density lipoprotein cholesterol (HDL). The diet emphasizes heart-healthy lifestyle choices that lower a person's total cholesterol and LDL levels while raising their HDL level.
