A level of 200 milligrams or less per deciliter for total cholesterol is ideal, and 40 milligrams per deciliter or higher for high-density lipoprotein, or HDL, is acceptable, explains WebMD. Low-density lipoprotein, or LDL, levels of 100 milligrams per deciliter for LDL are best.
Less than 150 milligrams per deciliter for triglycerides is good. Levels near these ranges are also generally acceptable, notes WebMD.
HDL, which is good cholesterol, is optimal at 60 or more milligrams per deciliter, states WebMD. An LDL level of 100 to 129 is considered near-optimal. Triglyceride levels over 150 increase a person's risk of heart disease. Eating a diet low in saturated fat and adding more fiber to the diet can decrease bad cholesterol numbers by as much as 30 percent. Additionally, exercise can also lower bad cholesterol and raise good cholesterol.
