Are Lentils Good for Your Heart?

Yes, lentils can support heart health as part of a balanced diet because their soluble fiber helps lower LDL cholesterol and they can replace foods high in saturated fat. Research on lentils specifically is promising but limited, and they are not a substitute for medical care.

Are lentils a heart-healthy food?

Plain lentils provide fiber and plant protein while being naturally low in saturated fat. That makes them a useful choice for a heart-conscious eating pattern, especially when they replace some processed meat or other foods high in saturated fat.

Lentils are one option among the best foods for heart health, not a food that protects the heart on its own. Overall eating habits, physical activity, smoking status, medical conditions and prescribed treatments also matter.

How do lentils support heart health?

Lentils contain soluble fiber, which can help lower LDL cholesterol by reducing cholesterol absorption in the digestive tract. High LDL cholesterol contributes to plaque buildup in arteries and raises the risk of cardiovascular disease. Eating lentils does not guarantee that an individual's cholesterol will fall.

Lentils also provide plant protein. Using them in place of a protein food high in saturated fat can reduce the saturated fat in a meal, depending on what else is added. For example, lentils cooked with vegetables and herbs offer a different nutritional balance from lentils served with a rich, salty sauce.

Lentils contain other nutrients and plant compounds, but their individual effects on the heart are less certain than the general roles of dietary fiber and replacing saturated fat. Heart-conscious choices extend to beverages too; see the best drinks for heart health.

What does the evidence say about lentils and heart health?

A 2024 review of lentils and health describes their fiber and protein content and discusses possible cardiovascular benefits. It is a review, not a clinical trial demonstrating that eating lentils prevents heart disease.

A 2022 overview of lentil compounds discusses substances including saponins, phytosterols and polyphenols, along with their potential health effects. Findings about isolated compounds or laboratory activity do not establish what a usual serving of lentils will do in a person's body.

These reviews support lentils as a nutritious food worth including in a balanced diet. They do not establish a specific amount of lentils that prevents heart attacks or strokes, or predict how much one person's cholesterol will change.

How can you include lentils in a heart-healthy diet?

Choose plain dried lentils or compare labels on canned and ready-to-eat lentils. Lower-sodium options help keep the overall meal's sodium down. If using canned lentils, draining and rinsing them can also reduce sodium.

Rinse dried lentils and cook them according to the package directions until tender. Prepared lentils can be added to salads, vegetable soups or whole-grain bowls. They also work in place of some meat in dishes such as chili or pasta sauce.

Pay attention to the rest of the dish: large amounts of salty seasonings, processed meat or high-saturated-fat sauces can make an otherwise heart-conscious meal less so. Herbs, vegetables and unsalted seasonings can add flavor without relying on as much salt.

If you are not used to eating fiber-rich foods, start with a small portion and increase gradually as tolerated. Lentils can cause gas or bloating for some people; a comfortable amount is one you can include without persistent digestive discomfort.

Who should be careful, and when should you see a doctor?

If you have chronic kidney disease or have been told to limit potassium or phosphorus, ask your clinician or a registered dietitian how lentils fit your individual plan. This is particularly important if you take medicines that can raise potassium, such as some blood pressure medicines. Do not change or stop medication on your own.

Avoid lentils if you have a known lentil allergy. If you have heart disease, high cholesterol or persistent digestive symptoms, discuss your eating plan and symptoms with a healthcare professional rather than relying on lentils as treatment.

Seek emergency medical help for sudden chest pain or pressure, severe difficulty breathing, or fainting. These symptoms need urgent assessment, regardless of what you have eaten.
