Cholesterol and Fats Cholesterol is a fat-like substance present in all body cells and is needed for many body processes.

Saturated fats raise these levels in the bloodstream, while polyunsaturated helps lower these levels. Monounsaturated lowers these levels while raising the levels of “good” cholesterol (HDL).
