Health Benefits of Beans and Why You Should Eat Beans

Beans are seeds from the Fabaceae family, commonly known as the legume, pea, or bean family. They are an affordable source of protein, fiber, and vitamins that offer many health benefits.

They usually grow in pods, which are capsules with several beans inside. These pods or capsules develop from flowers. Other legumes include peas, peanuts, and lentils.

In this article, we explore the nine health benefits of beans, including providing more protein and reducing the risk of heart disease.

The 9 Different Types of Beans Include:

1. Lima beans
2. Black beans
3. Black-eyed peas
4. Soybeans
5. Kidney beans
6. Garbanzo beans
7. Navy beans
8. Pinto beans
9. Red beans

4 Health Benefits of Beans

There are many health benefits to eating beans. Here are four major ones:

1. Protein Source
Adding beans to grains can turn an incomplete protein into a complete one. Protein is a vital nutrient that plays a key role in virtually everything the body does. Beans are high in amino acids, the building blocks of protein.

Protein sources can be divided into complete (containing all nine essential amino acids) and incomplete. Animal products, soy, and quinoa are complete proteins. Among beans, only soybeans contain all nine essential amino acids.

Incomplete proteins can be combined with nuts, seeds, dairy, or grains at a single meal or over the day to make complete proteins—for example, beans with rice or couscous, or black beans at lunch followed by almonds or cheese later.

Beans make an excellent protein source for vegetarians and vegans. They are also lower in calories and saturated fat than some other protein sources, such as dairy products.

2. Nutrient Dense Food

Beans contain several vital nutrients, including folate, which can help prevent neural tube defects in a fetus during pregnancy. Dried beans contain nearly double the folate of canned beans, so cooking from dried form is preferable, though canned beans still provide more folate than many foods.

Not getting enough folate can cause symptoms like weakness, fatigue, heart palpitations, loss of appetite, and irritability. Other important nutrients in beans include zinc, iron, magnesium, and fiber.

3. Antioxidant

Beans are rich in a type of antioxidant called polyphenols. Antioxidants fight the effects of free radicals, which are chemicals that affect a wide range of processes in the body, from physical aging to cancer and inflammation.

4. Better Heart Health
People who consume beans may be less likely to die from a heart attack, stroke, or other cardiovascular problems. A 2013 analysis of previous studies found a clear correlation between eating beans and reduced risk of coronary heart disease. Other research suggests beans may lower cholesterol, a key risk factor for heart disease and heart attacks.

Scientific Evidence and Case Studies on Health Benefits of Beans

1. Protein Completeness: Soybeans are one of the few plant-based complete proteins containing all nine essential amino acids, while most other beans are incomplete but can form complete proteins when combined with grains or other foods.

2. Nutrient Density: Beans are rich in micronutrients like potassium, magnesium, folate, iron, and zinc; dried beans provide higher levels of these nutrients compared to canned varieties, supporting overall diet quality and addressing nutrient shortfalls.

3. Antioxidant Properties: Beans contain high levels of polyphenols, which exhibit antioxidant effects that combat free radicals, potentially reducing inflammation and supporting protection against chronic diseases like cancer and cardiovascular issues.

4. Heart Health Improvement: Regular bean consumption is linked to reduced LDL cholesterol, lower risk of coronary heart disease (by up to 11-19% in some analyses), and decreased cardiovascular disease incidence through fiber, protein, and polyphenol mechanisms.

5. Overall Cardiometabolic Benefits: Diets rich in beans help lower body weight, blood pressure, inflammation, and cholesterol while improving blood sugar control and gut health, contributing to reduced risks of obesity-related diseases and better metabolic outcomes.

Summary of Health Benefits of Beans

Frequently Asked Questions

1. Are beans a complete protein source?

Most beans are incomplete proteins lacking one or more essential amino acids, but soybeans are complete; combining beans with grains or other foods creates a complete protein profile.

2. Which type of beans is the best source of complete protein?

Soybeans stand out as the only common bean type that contains all nine essential amino acids, making them a complete plant-based protein.

3. Why are dried beans better than canned beans nutritionally?

Dried beans (when cooked) provide nearly double the folate and higher levels of protein, fiber, iron, potassium, and magnesium compared to canned versions, with less sodium.

4. How do beans help with heart health?

Beans lower LDL (bad) cholesterol and reduce the risk of coronary heart disease and cardiovascular issues through soluble fiber, protein, and polyphenol content.

5. What antioxidants are found in beans?

Beans are rich in polyphenols, a type of antioxidant that combats free radicals, helping reduce inflammation, support anti-aging, and potentially lower risks of cancer and chronic diseases.

6. Can beans help with weight management?

Yes, their high fiber and protein content promotes satiety, supports better blood sugar control, and is linked to lower body weight in studies on legume-rich diets.

7. Are beans good for vegetarians and vegans?

Absolutely—they provide affordable, low-fat plant protein; combining varieties with other foods ensures complete amino acid intake without animal products.

8. Do beans provide significant folate benefits?

Yes, especially dried beans, which offer high folate levels to help prevent neural tube defects in pregnancy and avoid symptoms like fatigue or weakness from deficiency.

9. How do beans affect cholesterol levels?

Regular consumption can significantly decrease total and LDL cholesterol, as shown in multiple studies, contributing to better cardiovascular health.

10. What makes beans nutrient-dense?

They deliver substantial amounts of fiber, protein, folate, iron, zinc, magnesium, and potassium per serving, boosting diet quality and helping meet nutrient needs efficiently.
