You can lower triglyceride levels by reducing your intake of sugary foods, refined carbohydrates, sweetened beverages, and oily or fried dishes. Increase your consumption of vegetables, whole grains, and healthy fats, such as those found in nuts and fish. Regular physical activity, maintaining a healthy weight, and avoiding alcohol are also important. If your levels remain high despite lifestyle changes, your doctor may recommend tests and prescribe lipid-lowering medications, such as statins or fibrates.
