What is the difference between blood serum cholesterol and dietary cholesterol?

Dietary cholesterol is found in foods from animal sources, such as meats, liver and other organ meats, dairy foods, egg yolks, and shellfish. Cholesterol circulates in the blood throughout the body. Your liver produces more cholesterol when you eat a diet high in saturated and trans fats.

LDL is the bad cholesterol that you should avoid because it can increase your risk of heart disease.

Does dietary cholesterol raise blood cholesterol levels?
