Learning About Cholesterol in Food About cholesterol Cholesterol is a fat-like substance found in human and animal tissue. It is also found in all the foods you eat that come from animals. Plants (such as fruits, vegetables and soy products) do not contain cholesterol. Although cholesterol does a lot of good things in your body, you do not need to eat cholesterol in food. Your body can make all the cholesterol it needs from the fats you eat. Because of this, most experts now say you should eat less than 300 milligrams (mg) of cholesterol a day. But, for some, this may be too much. Having too much cholesterol in your diet can lead to high blood cholesterol levels.
Blood cholesterol Blood cholesterol is made up of good (HDL) and bad (LDL) cholesterol. The bad cholesterol can clog up your arteries by building up within the walls. This narrows your blood vessels and can lead to atherosclerosis, hardening of the arteries. Narrowed arteries reduce the blood flow (oxygen and nutrients) to your heart and body. This can lead to a heart attack or a stroke. High blood cholesterol levels are very unsafe when combined with these other risk factors for heart disease: artery
• smoking • high blood pressure
fatty deposits
• diabetes • obesity • a family history of heart disease
