Cholesterol is a fat-like substance present in body tissues and in the blood.
Our bodies need a certain amount of cholesterol to properly function, but if there is too much it can build up and lead to heart disease. As your cholesterol level increases, so does your risk for heart disease. It causes build-up of fatty deposits in the arteries and increases the risk of disease. It protects the arteries against the formation of fatty deposits and reduces the risk of heart disease. Triglyceride is the most common type of fat found in fatty tissue.
