LDL cholesterol levels should be less than 100 mg/dL. Levels of 100 to 129 mg/dL are acceptable for people with no health issues but may be of more concern for those with heart disease or heart disease risk factors. A reading of 130 to 159 mg/dL is borderline high and 160 to 189 mg/dL is high.
LDL is also called “bad” cholesterol because it blocks your blood vessels and increases your risk of heart disease. HDL is considered “good” cholesterol because it helps protect you from heart disease. The higher your HDL, the better. … Highlevels of triglycerides and low levels of HDL raise your risk for heart disease.
