Two kind of lipo-protein carry cholesterol throughout our body: low density lipoproteins (LDL) and high density lipoproteins(HDL). Having  healthy levels of both types of lipoproteins is important .
LDL cholestrol is some time called "bad" cholesterol . A high LDL level leads to buildup of cholesterol in our arteries . (Arteries are blood vessels that carry blood from our heart  to our body.
HDL cholesterol sometime is called "good" cholesterol. This is because it carries cholesterol from our body to the other parts our body and back to our liver. Our liver remove the cholesterol from our
body.
