Cholesterol
Cholesterol is a fatty substance that occurs in small balls in our bloodstream. The balls are surrounded by a layer of protein, which ensures that cholesterol can be transported properly through the blood. Cholesterol is often known as a 'bad' substance, but the body actually needs cholesterol to function properly. It is a building block for cells and hormones, it provides energy for metabolism and it plays a role in the production of bile. A small part of the required cholesterol is ingested through food, but most is produced in the liver. There, exactly enough cholesterol is normally produced for a properly functioning body.
