A healthy range for cholesterol levels is generally defined as having a total cholesterol level of less than 200 mg/dL. Within this range, LDL (low-density lipoprotein) levels should ideally be less than 100 mg/dL, as these are considered "bad" cholesterol and can lead to heart disease. Conversely, HDL (high-density lipoprotein) levels should be 60 mg/dL or higher, since these are "good" cholesterol that helps remove other forms of cholesterol from the bloodstream. Regular monitoring is essential for heart health.
