What LDL Cholesterol Measures

LDL (low-density lipoprotein) carries cholesterol from the liver to cells throughout your body. When there's more LDL than cells need, it can deposit in artery walls, forming plaques that narrow arteries and increase heart attack and stroke risk over time.

Normal Ranges

Optimal< 100 mg/dL
Near-optimal100–129 mg/dL
Borderline high130–159 mg/dL
High160–189 mg/dL
Very high≥ 190 mg/dL

Reference ranges may vary slightly by lab. Always use the range provided on your specific test report.

What Affects Your LDL Cholesterol Level

  • Diet high in saturated and trans fats
  • Low fiber intake
  • Lack of exercise
  • Excess body weight
  • Genetics (familial hypercholesterolemia)
  • Hypothyroidism

Foods That May Help

Oats & barley

Beta-glucan fiber directly lowers LDL

Fatty fish (salmon, mackerel)

Omega-3s reduce inflammation and triglycerides

Nuts (almonds, walnuts)

Healthy fats + fiber lower LDL by 5–10%

Avocado & olive oil

Monounsaturated fats raise HDL, lower LDL

Legumes

Soluble fiber binds cholesterol in gut

When to See Your Doctor

LDL consistently above 160 mg/dL usually warrants discussion with your doctor, especially if you have other risk factors like family history, smoking, or high blood pressure. Lifestyle changes typically reduce LDL by 10–30% before medication is considered.
