The body naturally makes cholesterol, which is a vital substance. Cholesterol is the starting agent for vitamin D and hormones, and it is used in the cellular membrane for structure. Many foods also contain cholesterol, and while some dietary cholesterol is OK, problems arise when people get too much.
Types
High-density lipoproteins (HDL) carry cholesterol back to the liver for recycling, which is why they are considered the "good" cholesterol. Low-density lipoproteins (LDL) carry cholesterol from the liver to different parts of the body, and they are considered the "bad" cholesterol.
Food
Most food products high in fat also have large doses of cholesterol. However, even vegetables have some amounts of cholesterol. Eggs, liver, lobster and shrimp are foods that have high levels of cholesterol.
Benefits
Cholesterol is used mainly as a precursor to vitamin D and hormones. Cholesterol circulating in the body is converted to vitamin D through exposure to sunlight.
Warning
High levels of cholesterol in the diet can lead to diseases like heart disease. LDL cholesterol is associated with plaque buildup in the arteries, leading to blood obstruction and possible heart attacks.
Medication
For people who have high levels of cholesterol, medication can control the amount of LDLs in the bloodstream. Statin medications like Lipitor help promote HDLs and lower LDLs. Statins block the body's production of cholesterol.
