HDL, LDL, triglycerides, lipoproteins – as with many health-related issues, the world of cholesterol is full of acronyms, big words and confusing facts. Chances are, if you visit your doctor on a regular basis, your cholesterol levels have been checked. Do you know what all the numbers really mean? Understanding what cholesterol is and the role it plays in your body could help you avoid serious problems, such as heart disease, heart attack and stroke.

Cholesterol is a waxy, fat-like substance that travels through the blood stream. The normal, healthy human body produces all the cholesterol it needs. High levels of saturated and trans fats in your diet can cause your liver to produce excess cholesterol. Eating animal products, such as fatty meats and full-fat dairy products, adds saturated fats to your diet.
