Optimal levels for HDL (good) cholesterol are considered 60 mg/dL and higher. Slightly less great but still good levels are between 50 and 59 mg/dL. Levels that cause concern are considered 39 mg/dL or lower for men, and 49 mg/dL or lower for women.
About one-fourth to one-third of your serum cholesterol is HDL, according to the AHA. The risk of heart disease is high when HDL is less than 40 mg/dL for men and less than 50 mg/dL for women. It is best to have an HDL level that is 60 mg/dL or more. Reducing trans fats in your diet will help your body produce more HDL cholesterol. Physical activity will help raise your HDL and lower your LDL levels.
