Understanding MyPlate's Dual Bean Classification
Dried beans, peas, and lentils, including black beans, are unique because they fit into two major MyPlate food groups. This dual role is a direct result of their rich nutritional content. They contain plant-based protein, iron, and zinc, similar to foods in the Protein Foods Group. They are also high in dietary fiber, folate, and potassium, which are usually associated with the Vegetable Group. This dual nature makes them a nutritional powerhouse.
How Black Beans Fit into Your Diet
The way black beans are counted in your daily MyPlate goals is flexible and depends on your overall diet. Official MyPlate guidelines provide clear rules for classification.
- For meat-eaters: If you eat meat, poultry, and fish regularly to meet your protein needs, black beans should be counted as part of your Vegetable Group. If a chicken breast meets your protein needs, the beans would be counted as a vegetable serving.
- For vegetarians and vegans: If your primary protein source is plant-based, count black beans as part of your Protein Foods Group intake. Additional servings can then be counted as vegetables.
This flexible approach allows everyone to track their nutrient intake and benefit from the vitamins, minerals, and macronutrients in black beans.
Nutritional Profile of Black Beans
Black beans are a nutritional powerhouse, providing many essential nutrients. A single cup (172g) of cooked black beans has approximately 227 calories, 15 grams of protein, 15 grams of fiber, and minimal fat. This protein and fiber combination can help manage weight by increasing fullness and regulating blood sugar. Beyond macronutrients, black beans are rich in iron, magnesium, and folate.
Protein Considerations
Black beans are considered an incomplete protein because they don't have all nine essential amino acids in sufficient amounts. However, this doesn't diminish their value. Combining black beans with other incomplete protein sources, like grains (e.g., rice) or nuts, creates a complete protein. Traditional pairings like black beans and rice have long been culinary staples, providing a nutritionally complete meal.
Comparing Black Beans to Other Legumes
Comparing black beans with other legumes helps to understand their nutritional aspects. Here's a comparison:
| Feature | Black Beans | Chickpeas (Garbanzo Beans) | Kidney Beans |
|---|---|---|---|
| Protein (per 1 cup cooked) | ~15g | ~15g | ~15g |
| Fiber (per 1 cup cooked) | ~15g | ~13g | ~13g |
| Primary MyPlate Group | Protein and Vegetable | Protein and Vegetable | Protein and Vegetable |
| Texture | Soft, creamy | Firm, nutty | Firm, dense |
| Common Use | Soups, dips, burgers | Hummus, salads | Chili, stews |
Ways to Use Black Beans in Meals
Black beans are versatile and easy to add to meals. Their mild flavor works well with many ingredients and cuisines.
- Salads: Add cooked and chilled black beans to salads for extra protein and fiber.
- Soups and Chili: Add black beans to soups or use them in chili.
- Burritos and Tacos: Use black beans as a filling for burritos, tacos, or enchiladas.
- Dips and Spreads: Blend black beans with lime juice, cilantro, and spices to make a dip.
- Veggie Burgers: Mash black beans to make flavorful, high-protein veggie burgers.

Conclusion
Black beans belong to both the Protein Foods Group and the Vegetable Group in MyPlate. This unique classification highlights their nutritional value, including plant-based protein, dietary fiber, and essential minerals. Whether they are counted as a protein or vegetable depends on the overall diet, but their health benefits are clear. Including black beans in your meals provides a nutritious and satisfying food for a balanced diet.
Note: When using canned black beans, choose low-sodium options and rinse them to reduce sodium.
