            "definition": "is made up of the LDL, HDL, and TG. A normal cholesterol level is below 200 mg/dL, but ideally it should be below 150. However, the relative amounts of the LDL and HDL affect how \"dangerous\" a given total cholesterol level is. For example, if your total cholesterol is 230, and your HDL is 70, you are in a less risky range than if your total cholesterol is 190 and your HDL is 30. This is because the LDL accompanying the first of these profiles would likely be significantly lower than that of the second.",
