Lowering Cholesterol Through Diet
In brief
Which foods help lower LDL cholesterol?
Oats and oat bran, nuts, fatty fish, beans and legumes, avocados, plant sterols, olive oil and soy products each have evidence for lowering LDL cholesterol, with effects ranging from about five percent up to thirteen and a half mg/dL depending on the food and amount. Red meat, full-fat dairy, fried foods, processed baked goods and coconut oil should be limited since they raise LDL. Combining several of these foods in a 'portfolio diet' approach can lower LDL by up to thirty percent, alongside exercise, weight loss, quitting smoking and limiting alcohol.
High cholesterol is a major risk factor for heart disease, but the good news is that dietary changes can be remarkably effective, sometimes reducing LDL cholesterol by 20-30%. This guide reveals the most powerful cholesterol-lowering foods and strategies backed by science.
Understanding Cholesterol Numbers
Total Cholesterol: Below 200 mg/dL ideal
LDL ("Bad"): Below 100 mg/dL optimal
HDL ("Good"): Above 60 mg/dL protective
Triglycerides: Below 150 mg/dL healthy
