Beans & Nutrition

Beans are a simply delicious, naturally nutritious food. We’re talking about dry edible beans, beans that are harvested when the beans are dry in the seed pod.

All types of beans—including black, cranberry, Great Northern, dark red kidney, light red kidney, white kidney, navy, pink, pinto, and small red—are good sources of protein, excellent sources of fiber, and naturally fat-free, sodium-free, and cholesterol-free. Many types are also good sources of potassium.

The U.S. Dietary Guidelines for Americans recommends eating about 1 to 3 cups of legumes, including beans, per week. If you eat about ½ cup of beans every day, you’ll meet the weekly Dietary Guidelines for legumes.

And when you consider the fact that USDA MyPlate guidelines count beans as both a vegetable and a plant-based protein source, you’ll begin to see how easy it is to put more beans in your diet.

Data based on ½ cup servings of beans that have been cooked from the dry form and drained of cooking liquid. Canned beans will contain more sodium.

Complex carbohydrates, also referred to as dietary starch, are made of sugar molecules strung together like a necklace. Complex carbohydrates are typically rich in fiber.

The majority of the calories in dry beans come from carbohydrates in the form of starch, resistant starch (digested by beneficial bacteria in the gut), and small amounts of non-starch polysaccharides (also digested by beneficial gut bacteria).

Being rich in complex carbohydrates, as well as a good source of protein, beans have a low glycemic index. This makes them an ideal food for the management of insulin resistance, diabetes, and hyperlipidemia. (Foster-Powell, 2002; Rizdalla, 2002)

Beans contain some complex sugars called oligosaccharides (all-uh-go-SACK-are-rides), which 
are non-digestible, fermentable fibers. They are broken down by beneficial bacteria in the colon, which may result in gas production and flatulence. There is increasing research and attention about the health of the gut or gastrointestinal (GI) tract, and how certain foods benefit or harm the gut (Zanteson, 2012). Beans may be a very important food for a healthy gut!

Dry beans are rich in both soluble and insoluble fibers. (Tosh, 2010)

Soluble fiber traps dietary cholesterol inside the digestive tract. The cholesterol is then excreted versus being absorbed, which helps to lower blood levels of LDL cholesterol, especially if LDL cholesterol levels were high to begin with.

Dry beans also provide substantial amounts of insoluble fiber, which help attract water to the stool and keep you regular. This may help to combat constipation, colon cancer, and other digestive health conditions. (Lanza, 2006)

Dry beans are a good source of plant-based protein and have therefore been identified as a meat alternative by the USDA My Plate food guidance system. (USDA Dietary Guidelines, 2020)

Beans contain between 21 to 25% protein by weight, which is much higher than other sources of vegetable protein. (USDA Nutrient Database)
Regular intake of dry beans is extremely important worldwide as they provide a good source of protein at a low cost compared to animal protein like beef, pork, and chicken.

Most types of beans are good sources of potassium, a mineral that promotes healthy blood pressure levels. Beans are also excellent sources of copper, phosphorus, manganese, and magnesium—nutrients that many Americans don’t get enough of. Most types of dry beans are rich sources of iron, which makes them important for vegetarians and vegans who do not get an animal source of iron. Dry beans are an excellent source of the water-soluble vitamins thiamin and folic acid and a good source of riboflavin and vitamin B6.
