Like other bean varieties, pinto beans are a plant-based protein that adds flavor, texture and color to an array of dishes. What might surprise you is that pinto beans are the most popular type of beans eaten by Americans, claiming the top spot among all the bean varieties. What makes this versatile bean so well-loved? Are pinto beans healthy? Read on to find out the nutrition, health benefits, potential drawbacks and ways to enjoy pinto beans.

What Are Pinto Beans?

Pinto beans are tan-colored, oval-shaped beans with specks of reddish-brown. Metaphorically, each pinto bean resembles a painting, and in Spanish "pinto" means painted. Pinto beans are a staple in Mexican and Southwestern American cuisine. The beans are soft, creamy, nutty and earthy, making them perfect for burritos, fajitas, tacos, quesadillas.

You can find pinto beans in grocery stores as dried beans or canned beans. They are affordable, easy to prepare and nutritious. This cholesterol- and gluten-free plant-based protein is vegetarian- and vegan-friendly, making it a commonly used ingredient in many savory and sweet dishes.

Health Benefits of Pinto Beans

Excellent plant-based protein source

Every 1/2-cup serving of cooked pinto beans provides 8 grams of protein, which makes them an excellent protein option for meals. Adding them to a recipe can boost the amount of protein in the dish. Their protein and iron content makes pinto beans an ideal food choice for vegetarians and vegans. However, pinto beans are not a complete protein, meaning that they do not contain all the essential amino acids which the body needs to get from food. Vegetarians and vegans will need to eat a variety of plant-based foods, such as whole grains, nuts and seeds, to ensure that they obtain all the essential amino acids.

High in fiber

Every 1/2-cup serving also provides 8 grams of dietary fiber, which is one-fifth to one-third of your daily recommended dietary fiber consumption, depending on your age and gender. Fiber gives you the feeling of fullness, which can make you less likely to overeat. More importantly, eating pinto beans, and other foods with fiber, regularly provides many health benefits, such as improved heart health, digestive health, cholesterol, weight maintenance and more.

Low-glycemic food

While pinto beans contain carbohydrates, they do not raise blood sugar quickly because they are slowly digested and absorbed. For this reason, pinto beans are considered a low-glycemic food. This is largely thanks to their high fiber and protein content, making them a healthy choice for people with diabetes.

Rich in folate

Pinto beans are an excellent source of folate, with every 1/2-cup serving providing more than one-third of your daily recommended intake. Folate is essential for making cells, tissues and red blood cells in the body. It is also a vital nutrient for preventing neural tube defects in the early stages of pregnancy.

Loaded with antioxidants

Beans have bioactive compounds, such as flavonoids, which are believed to act as antioxidants. Pinto beans are particularly rich in kaempferol, one of the many antioxidants present in plant-based foods. Kaempferol has properties that may effectively reduce inflammation and protect cells against free radicals, which can reduce risk of cancer.

Potential Drawbacks of Pinto Beans

Lack of vitamin B12

Pinto beans do not contain any vitamin B12, an essential nutrient for the brain and nerves and for making red blood cells and supporting DNA production. Vitamin B12 is primarily found in animal sources, including meat, poultry, clams and fatty fish such as salmon and trout. You can also find vitamin B12 in eggs, cheese and yogurt. Vitamin B12 is also added to fortified cereals and some plant-based beverages. Make sure to read the Nutrition Facts label and the ingredients list to ensure that B12 is added.

If you are not eating enough vitamin B12-rich foods or have issues with absorbing vitamin B12, you may need a B12 supplement. Speak with your primary health care provider or registered dietitian to find out if supplementation is right for you.

Gas and bloating

Eating beans may bring discomfort to some people, causing unpleasant symptoms such as gas and bloating. These symptoms are due to raffinose, a type of carbohydrate that does not get digested. When it reaches your colon, the bacteria present there will break it down, creating the byproduct gas.

If you are sensitive to gas and bloating, consider soaking dry beans overnight. Doing so may help reduce the amount of raffinose present. You may want to be mindful of how much pinto beans and other legumes you eat at one sitting to reduce these unpleasant symptoms.

Drinking plenty of water with your fiber-rich meals throughout the day can bulk up your stools and make them move along your digestive tract faster and smoother (goodbye, constipation!).

How to Enjoy Pinto Beans

One of the top reasons for pinto beans' popularity among Americans is their versatility. You can enjoy them in many ways: as a side dish like these Spiced Pinto Beans or as a protein for a meatless meal, like our Vegetarian Pinto Bean Sloppy Joes. You can also use them in soups or add them to salads, stews, rice dishes and more. Because of their soft texture, pinto beans are also perfect for dips, spreads and fillings.

Using canned pinto beans rather than dried beans for our Chipotle Chicken and Quinoa Burrito Bowl and other dishes is super-efficient for busy mealtimes. You can keep the salt content minimal by draining the brine and rinsing the canned beans before consumption. If you prefer to use dried beans, soaking them overnight helps to speed up the cooking time.

Bottom Line

Pinto beans are highly nutritious. Packed with protein, fiber and many other essential nutrients, pinto beans may help promote bowel regularity, control your blood sugars and reduce your risk for cancer and other chronic diseases. Their affordability and versatility also make them a great staple in your pantry. Start enjoying them at any time of day with our pinto bean recipe collection.
