Dietary Cholesterol & LDL

LDL comprises 60–70% of total blood lipoproteins and is responsible for carrying cholesterol particles throughout your body. Having a lot of cholesterol carried by LDL lipoproteins is associated with an increased risk of heart disease. In fact, the higher the level, the greater the risk. There are different types of LDL, mainly broken down by size. They are often classified as either small, dense LDL or large LDL. Studies show that people who have mostly small particles are at a greater risk of developing heart disease than those with mostly large particles. The amount of cholesterol in your diet and the amount of cholesterol in your blood are very different things. Although it may seem logical that eating cholesterol would raise blood cholesterol levels, it usually doesn't work that way. The body tightly regulates the amount of cholesterol in the blood by controlling its production of cholesterol. When your dietary intake of cholesterol goes down, your body makes more. When you eat greater amounts of cholesterol, your body makes less. Because of this, foods high in dietary cholesterol have very little impact on blood cholesterol levels in most people.
