Why cholesterol became so important to health conscious individuals?

Cholesterol is a fat-like substance that is made in the liver, other cells, and can be found in some foods. To function properly, the body needs cholesterol to produce hormones, etc., but only a limited amount. When there is too much a plaque will build up in the body's arteries, making it harder for blood to flow through to the heart. This can lead to atherosclerosis which, in turn, leads to heart disease. If too little oxygen carrying blood cells reach the heart chest pain will result (angina) and if there is a total cut off, the result is a heart attack.
