Cholesterol is a waxy, fat-like substance found in all cells
of the body. Cholesterol is also found in some of the foods that we eat. Our
body does need cholesterol to make hormones, vitamin D, and substances that
help digest foods. Since cholesterol is fatty, it does not mix with blood and
is carried in small packages called lipoproteins. These basically contain fat
or lipid inside and protein on the outside.
