Key Foods That Can Help Protect Your Arteries and Support Heart Health

HEALTH — No single food can “clean” or unclog arteries, but a heart-healthy eating pattern can help lower cardiovascular risk factors, including high LDL cholesterol, high blood pressure and inflammation.

The American Heart Association’s 2026 dietary guidance emphasizes vegetables and fruits, whole grains, healthy protein sources and unsaturated fats, while recommending less saturated fat, sodium, added sugar and ultra-processed food.

Fatty Fish

Salmon, sardines, mackerel and trout provide omega-3 fatty acids. Regular fish intake can support heart health and help lower triglycerides.

Nuts

Walnuts, almonds and other unsalted nuts provide unsaturated fats, fibre and plant compounds. They work best as replacements for foods high in saturated fat.

Beans and Lentils

Legumes are rich in soluble fibre and plant protein. Adding them regularly can help improve overall diet quality and support healthier cholesterol levels.

Whole Grains

Oats, barley, brown rice and other whole grains provide fibre. Soluble fibre, particularly beta-glucan in oats and barley, can help reduce LDL cholesterol.

Fruits and Berries

Berries, apples, citrus fruits and other fruits supply fibre, vitamins and antioxidant plant compounds as part of a heart-friendly diet.

Leafy Greens and Other Vegetables

Spinach, kale and a wide variety of colourful vegetables provide fibre and micronutrients. A vegetable-rich diet is consistently recommended for cardiovascular health.

Olive Oil and Other Unsaturated Fats

Using liquid plant oils such as olive oil instead of butter and other saturated-fat sources can improve the overall fat profile of the diet.

Avocado

Avocado supplies fibre and monounsaturated fat and can be a useful replacement for foods rich in saturated fat.

The Bigger Picture Matters

Artery health depends on the overall dietary pattern rather than one “miracle” ingredient. A balanced diet built around minimally processed plant foods, fish and healthy fats—combined with regular physical activity, not smoking, adequate sleep and management of blood pressure, cholesterol and diabetes—offers a stronger approach to cardiovascular prevention.

Foods to Limit

Heart-health guidance recommends limiting foods high in saturated and trans fats, processed meats, refined carbohydrates, excess sodium, added sugars and heavily ultra-processed foods.

Important: Existing arterial plaque cannot simply be removed by eating particular foods. People with high cholesterol, cardiovascular disease, diabetes or other risk factors should follow medical advice and prescribed treatment.
