When you think of foods with antioxidants, you probably think of dark, leafy greens or colorful berries. But one of the health benefits of pinto beans and kidney beans is the tremendous amount of antioxidants packed into every bean. "Red kidney beans and pinto beans are among the highest antioxidant foods—even higher than berries, peppers, and things we usually think about as antioxidants," Hanway says.
Whether you're looking to chow down on lima beans or green beans (which are actually technically just a legume), beans are also a significant source of some essential minerals. "Most are high in much-needed minerals such as magnesium, iron, zinc, and potassium," Hanway says.
2. Protein
Protein is a vital nutrient that plays a key role in maintaining and repairing the body. Beans are high in amino acids, the building blocks of protein.
There are 20 amino acidsTrusted Source, and nine of these are essential. There are also two types of protein sources: complete and incomplete.
Animal products, soy, and quinoa are all complete proteins, which means they contain all nine essential amino acids.
However, of all the types of beans, only soybeans contain all nine amino acids.
People can combine incomplete proteins with nuts, seeds, dairy products, or grains at a single meal or throughout the day to make complete proteins.
For example, a person can:
eat beans with rice or couscous for lunch
have black beans at lunch with almonds or cheese
Beans make an excellent source of protein for vegetarians and vegans.
They are also lower in calories and saturated fat than some other protein sources, such as meat and full fat or low fat dairy products.
Examples of the protein content of beans are:
A 1-cup, or 40 gramsTrusted Source (g), serving of canned black beans provides 14.5 g of protein, 16.6 g of fiber, and 4.56 milligrams (mg) of iron.
A 1-cup, or 155 gTrusted Source, serving of shelled edamame beans provides 18.5 g protein, 8.06 g fiber, and 3.52 mg iron.

3. Folate
Beans contain several vital nutrients, including folate. Folate is essential for overall health, to make healthy red blood cells, and help prevent neural tube defects in a fetus during pregnancy.
A 1-cup, or 155gTrusted Source, serving of shelled edamame beans provides 482 micrograms (mcg) of folate.
4. Antioxidants
According to researchTrusted Source, beans are rich in polyphenols, which are a type of antioxidant.
Antioxidants fight the effectsTrusted Source of free radicals, which are damaging chemicals that the body produces during metabolism and other processes.
Free radicals can cause cell damage that can result in various diseases. Antioxidants help the body remove free radicals. In this way, antioxidant-rich foods, such as beans, can help protect the body from disease.

5. Heart health
People who consume beans regularly may be less likely to die of a heart attack or other cardiovascular problem. The authors of a 2017 meta-analysisTrusted Source suggested that one reason for the decrease in cardiovascular risk was that people had replaced higher fat animal meat proteins with beans.
A 2013 review and meta-analysisTrusted Source found a clear correlation between eating beans and a lower risk of coronary heart disease.
Other research suggests that nutrients in beans may help lower cholesterol. High cholesterol is a risk factor for heart disease and heart attacks.
There is evidenceTrusted Source that a high fiber diet may help reduce the risk of cardiovascular disease.
A half-cup, or 88 gTrusted Source, serving of black beans provides about 14 g of fiber, which is over half an adult’s daily requirement for fiber.

6. Reduced risk of cancer
Some studies have shown that beans act as antioxidants and anti-inflammatory agents. These effects could reduce the risk of cancer.
Research published in 2015 analyzed whether beans might have antioxidant properties that fight intestinal cancer. The results suggested that black beans had the highest antioxidant activity.
A 2016 study also found that chemicals in Northeast China black beans could slow the growth of colorectal cancer by preventing cancer cells from multiplying.

7. Diabetes and glucose metabolism
Beans may help stabilizeTrusted Source blood glucose levels or even prevent diabetes. Beans are high in fiber, which can help lower blood glucose.
The author of a 2018 reviewTrusted Source concluded that consuming a high fiber diet could reduce the risk of type 2 diabetes. There was also evidence that it may help lower blood sugar in people who already have the condition.
Another studyTrusted Source looked specifically at the effect of adding a cup of legumes to the daily diet of people with type 2 diabetes. This study showed a reduction in blood sugar levels and lower blood pressures in the group who ate beans over the control group who included more whole wheat fiber.

8. Preventing fatty liver
Fatty liver happens when fats accumulate in the liver. It can develop alongside obesity, high cholesterol, high blood pressure, and other aspects of metabolic syndrome.https://www.nhs.uk/conditions/non-alcoholic-fatty-liver-disease/
Doctors base the treatment of fatty liver disease on weight loss and controlling blood sugars, as well as reducing blood levels of fats, such as triglycerides and low-density lipoprotein (LDL), or bad cholesterol. Replacing higher fat animal proteins with beans is a good step towards better liver health.
Here, learn about some more foods that can help protect the liver.
9. Controlling appetite
When a person eats beans, the fiber and healthful starches they contain can help create a feeling of fullness and satisfaction.
As a long-term dietary strategy, this could help prevent overeating and may lead to weight loss, according to a 2013 reviewTrusted Source.
10. Improving gut health
ResearchTrusted Source has shown a variety of beans, especially black beans, enhance gut health by improving intestinal barrier function and increasing the number of beneficial bacteria. This may help prevent gut-associated diseases.
Healthful gut bacteria also support immune system function and may promote weight loss. Beans feed the healthful gut bacteria colonies.
