What Is Your Cholesterol Supposed to Be?

Cholesterol levels are measured by blood lipid profiles that produce readings for total cholesterol and more specific numbers for HDL, LDL and triglyceride levels. The National Heart, Lung and Blood Institute recommends total cholesterol readings of 200mg/dL or less and sets borderline levels at 200-239mg/dL. Dangerous levels are 240mg/dL or higher.

HDL cholesterol

• HDL, or high-density lipoprotein, is known as the "good" cholesterol because it is linked to decreased risks of heart attack and stroke. Recommended levels are different for men and women, but those with 60mg/dL generally are at lower risks for coronary disease.

LDL cholesterol

• Low-density lipoprotein (LDL) is considered the "bad" cholesterol because it is linked to heart disease. Those at high-risk for heart attacks should aim for levels of 70mg/dL or lower and people without increased risks should aim for 100mg/dL or less of LDL cholesterol.

Triglycerides

• Triglycerides are a common type of fat produced in the body and consumed from foods. Studies show that above-normal levels of triglycerides are linked to heart disease and stroke. Normal levels should be less than 150mg/dL and levels above 200mg/dL are considered high.

Screening

• The American Heart Association recommends blood-lipid panels to screen cholesterol levels starting at age 25, and every five years thereafter. For children with a family history of heart disease, the American Academy of Pediatrics recommends testing between ages 2 to 10.

Maintaining Healthy Cholesterol Levels

• Comprehensive cholesterol-lowering plans include changes in diet, increased physical activity and smoking cessation. The American Heart Association recommends at least 30 minutes of physical activity, preferably every day. Diets low in saturated fat and high in fiber and plant-based foods can also help to reduce cholesterol levels.
