Are Almonds Good for Your Heart?

Yes, almonds can support heart health when they replace foods high in saturated fat, because their unsaturated fats can help lower LDL cholesterol.

Are almonds a heart-healthy choice?

Almonds can be part of a heart-healthy eating pattern, but they are not a stand-alone way to prevent or treat heart disease. The benefit depends on what they replace and on your overall diet, health and treatment plan.

For example, choosing unsalted almonds instead of a snack made with butter can reduce the amount of saturated fat in that snack. Adding almonds to a diet without changing other foods may not have the same effect.

Almonds are one option among the best foods for heart health. You do not need to eat them if you dislike them or cannot eat them safely.

How might almonds support heart health?

Almonds contain mostly unsaturated fats. Replacing saturated fat with unsaturated fat can help lower LDL cholesterol, often called “bad” cholesterol. High LDL cholesterol contributes to plaque buildup in arteries, which increases the risk of heart attack and stroke.

Almonds also provide fiber, a component of a heart-healthy eating pattern. The cholesterol effects of fiber depend on its type and amount, however, so you should not assume that the fiber in a serving of almonds will produce a particular change in your cholesterol.

What you eat alongside almonds matters, too. A balanced pattern with a variety of foods can support heart health more reliably than focusing on any single ingredient. For another part of that pattern, see the best drinks for heart health.

What does the evidence say about almonds?

General dietary guidance supports replacing saturated fats with unsaturated fats to help manage LDL cholesterol. That principle helps explain why almonds can be a useful substitution for a food high in saturated fat.

This page does not cite almond-specific clinical studies, so it cannot quantify how much eating almonds changes cholesterol or the risk of a heart attack. It would also be inaccurate to claim from the evidence presented here that almonds prevent heart disease.

That limitation does not mean almonds are ineffective. It means the size of any almond-specific benefit, and whether it translates into fewer heart events, cannot be established from the evidence presented on this page. Cholesterol is also only one factor in heart health; blood pressure, smoking, activity, genetics and other factors matter.

How can you eat almonds for heart health?

Choose plain, unsalted almonds when possible. Raw or dry-roasted almonds can both fit; check the label because some roasted or flavored products contain added salt, sugar or other ingredients. If you have been advised to limit sodium, compare the sodium listed for the serving size on the package.

Try a small handful of almonds in place of a snack high in saturated fat, such as a pastry made with butter. You can also add plain almonds to a meal or snack you already enjoy, while considering whether they are replacing another food or simply adding to it.

Almonds are energy-dense, so a portion that fits your needs is more useful than eating unlimited amounts because they are considered healthy. If you are unsure what portion suits your health goals, ask a registered dietitian. There is no need to force almonds into your diet to make it heart-healthy.

Who should be careful with almonds?

Avoid almonds if you have an almond or tree-nut allergy, and follow your clinician’s advice about other nuts and possible cross-contact. Trouble breathing, throat swelling or feeling faint after exposure can signal a severe allergic reaction; call emergency services immediately and use prescribed epinephrine if available.

Whole almonds can be a choking hazard for young children. Ask a pediatric clinician about safe forms and preparation for your child. If you have kidney disease and have been told to restrict nutrients such as potassium or phosphorus, ask your care team whether almonds fit your individual plan.

If you have high cholesterol, high blood pressure or heart disease, discuss dietary changes with your clinician or dietitian. Keep taking prescribed medication unless your clinician advises otherwise; almonds are not a substitute for treatment.

Chest pain or pressure, especially with shortness of breath or discomfort in the arm, jaw or back, needs urgent attention. Call emergency services immediately rather than trying to manage these symptoms with food.
