Is Olive Oil Good for Your Heart?

Yes, olive oil can support heart health when it replaces foods high in saturated fat, because its unsaturated fats can help lower LDL cholesterol.

When is olive oil a heart-healthy choice?

Olive oil is most useful as a replacement, not as an extra ingredient added to an otherwise unchanged diet. For example, using olive oil instead of butter is a way to swap some saturated fat for unsaturated fat.

It is one of the best foods for heart health when used as part of an overall eating pattern that also includes vegetables, fruit, whole grains and other nutritious foods. Olive oil is not a treatment for heart disease, and no single food can guarantee protection from a heart attack or stroke.

How does olive oil support heart health?

Olive oil is rich in monounsaturated fat. Replacing saturated fat with unsaturated fat can lower LDL cholesterol, often called “bad” cholesterol; high LDL cholesterol contributes to the buildup of plaque in arteries.

Olive oil also contains naturally occurring plant compounds, including polyphenols. These compounds are being studied for their possible effects on inflammation and cholesterol oxidation, but their individual contribution to heart outcomes is less certain than the benefit of replacing saturated fat with unsaturated fat.

Different kinds of olive oil can fit into a heart-conscious diet:

Choice	What to know
Extra virgin olive oil	Less refined and retains more naturally occurring plant compounds.
Refined olive oil	Still contains predominantly unsaturated fat and can be used in place of saturated fats.
Butter or other solid fats	Generally contain more saturated fat; replacing them with olive oil can improve the fat balance of a meal.

The rest of the meal matters too. Olive oil does not undo the effects of a dietary pattern that is consistently high in saturated fat or low in fiber-rich foods.

What does the evidence say about olive oil and heart health?

A 2024 narrative review of extra virgin olive oil and metabolic health discusses its potential effects on factors related to cardiovascular health. The review considers possible mechanisms and a range of metabolic outcomes, rather than establishing that olive oil alone prevents heart disease.

A narrative review is useful for summarizing research, but it is not the same as a systematic review or a randomized trial designed to measure a specific heart outcome. Research has not established an exact amount of olive oil needed to prevent a heart attack or shown that its plant compounds work independently of the rest of the diet.

The practical takeaway is stronger and more modest: replacing saturated fat with unsaturated fat is a well-established heart-healthy approach, and olive oil is one way to make that substitution. A person's overall diet and other cardiovascular risk factors still matter.

How can you use olive oil for heart health?

Use olive oil where it will replace a source of saturated fat. Try it instead of butter on vegetables, in a dressing, or when cooking beans or fish. Choosing olive oil does not require eliminating every food that contains saturated fat; the aim is to improve the overall pattern of choices.

Extra virgin olive oil works in dressings and can also be used for sautéing. Avoid overheating it until it smokes; if oil has burned, discard it and start again. Store olive oil sealed, away from heat and light, to help preserve its quality.

Olive oil is calorie-dense, so adding generous amounts without replacing another food can increase the energy in a meal. There is no proven heart-protective dose that everyone needs, and drinking olive oil is not necessary to get its benefits.

Heart health also depends on the broader choices you make at meals; for a related guide, see the best drinks for heart health.

Who should be careful, and when should they seek medical help?

If you have heart disease, high LDL cholesterol, diabetes or high blood pressure, discuss your overall eating plan and risk factors with your healthcare professional. Olive oil can be part of that plan, but it does not replace prescribed medication or follow-up care. Do not stop or change medication without medical advice.

If you have gallbladder disease, find that fatty meals cause symptoms, or have been prescribed a low-fat diet, ask your clinician or a registered dietitian how olive oil fits your individual plan. People with a medically prescribed diet during pregnancy or for a child should follow their clinician's advice rather than assume a general dietary swap is appropriate.

Call emergency services immediately for possible signs of a heart attack, such as new chest pain or pressure, unexplained shortness of breath, or discomfort spreading to the arm, back or jaw. Do not wait to see whether a food or drink helps.
