Are Black Beans Good for Cholesterol?

Yes, black beans can help lower LDL cholesterol when they replace foods high in saturated fat in a balanced diet, partly because their soluble fiber helps the body remove cholesterol. Animal research offers some support, but direct evidence specific to black beans is limited. Cook them thoroughly, and discuss cholesterol treatment or dietary restrictions with a clinician.

Are black beans a good choice for high cholesterol?

Black beans can be a useful part of an eating pattern intended to improve cholesterol, especially when they take the place of foods high in saturated fat. They provide fiber and plant protein without the saturated fat found in some meats and dairy products.

That does not mean adding black beans to any meal will reliably lower your cholesterol. The rest of your diet, your inherited risk and whether you need medication matter too. For more ways to build a balanced eating pattern, see the best foods for high cholesterol.

How might black beans help cholesterol?

Black beans contain soluble fiber, which can bind some bile acids in the digestive tract and help remove them in stool. Because the body uses cholesterol to make bile acids, replacing those lost can help reduce LDL cholesterol in the blood.

LDL is often called “bad” cholesterol because high levels contribute to plaque buildup in arteries. Eating soluble fiber as part of an overall balanced diet can help lower LDL, although the effect of a particular serving of black beans cannot be predicted from the available evidence.

The food black beans replace matters as well. For example, using black beans instead of a fatty meat in a meal can reduce saturated fat intake. That swap, rather than an effect unique to black beans, may contribute to a healthier cholesterol pattern.

What you drink can also fit into an overall cholesterol-conscious eating pattern; see the best drinks for high cholesterol.

What does the evidence say about black beans?

The strongest practical reason to choose black beans is the broader evidence supporting soluble fiber and replacing saturated fat in the diet. That is different from proving exactly how much eating black beans will lower cholesterol in a person.

In a study of black beans fed to rats, cholesterol outcomes varied with the way the beans were processed. A preparation involving boiling and coarse milling lowered LDL cholesterol, while a different preparation lowered total cholesterol compared with certain other diets. The study shows a possible effect in animals, not a reliable result or serving recommendation for people.

A mouse study of black soybeans involved a different species, so its findings should not be attributed to the black beans discussed here. Overall, evidence specific to black beans is limited, and it cannot establish how much a person's cholesterol will change.

How can you use black beans for cholesterol?

Use cooked black beans in meals where they can replace some or all of an ingredient high in saturated fat. Try them in a grain bowl with vegetables, in a bean-and-vegetable chili, or as a filling for a tortilla with vegetables and salsa.

Consider the whole dish. Black beans served with a large amount of fatty meat, cheese or butter may not make the same useful swap as black beans served with vegetables and unsaturated fats. Choose a preparation you enjoy and can include regularly rather than relying on a single meal.

Canned black beans are convenient; look for no-salt-added or lower-sodium options when available. Draining and rinsing canned black beans can remove some sodium. If using dried black beans, follow the package cooking directions and cook them thoroughly rather than eating them raw or undercooked.

If you are not used to eating beans, start with a small amount and increase gradually. This can make it easier to tolerate the extra fiber; drink enough fluid unless your clinician has told you to limit it.

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

If you have high cholesterol, ask a clinician about your overall cardiovascular risk and whether you need a lipid test or treatment. Black beans are not a substitute for prescribed cholesterol medicine. Continue taking medicines as directed, and do not stop or reduce them without medical advice.

If you have chronic kidney disease or have been told to limit potassium, ask your clinician or kidney dietitian whether black beans fit your diet. If you have a digestive condition or have been advised to follow a low-fiber diet, ask before increasing beans. During pregnancy, or when planning a diet for a child with high cholesterol, seek individualized advice from a clinician.

High cholesterol usually has no symptoms, so do not wait to feel unwell before seeking routine care. Get emergency help for chest pain or pressure, sudden trouble breathing, sudden weakness on one side, or trouble speaking; these can be signs of a heart attack or stroke.
