The Top Contenders in Protein Content
Beans and legumes are nutritional powerhouses, but their protein content can vary. For those looking to maximize their protein intake from plant-based sources, focusing on certain varieties can be especially beneficial. Here are some of the highest-protein beans and legumes that can help you meet your daily needs.
Soybeans (Edamame)
Often hailed as the king of plant-based protein, mature soybeans provide a whopping 30.2 grams of protein per cooked cup. They are also unique among beans because they are a 'complete protein,' containing all nine essential amino acids that our bodies cannot produce on their own. This makes them a particularly valuable food for vegans and vegetarians. Immature soybeans, known as edamame, are also an excellent source of protein and can be enjoyed as a snack, in salads, or stir-fries. In addition to protein, soybeans are rich in iron, magnesium, and phosphorus, providing a well-rounded nutritional profile.
Lentils
Lentils are another top-tier choice for protein. While technically a pulse within the legume family, they are regularly grouped with beans due to their similar nutritional benefits and culinary uses. Cooked lentils provide nearly 18 grams of protein per cup. They are a budget-friendly and quick-cooking option that also offers substantial amounts of fiber, iron, and folate. Lentils come in various types, including red, brown, and green, with slightly different cooking times and textures. They are incredibly versatile and are staples in dishes ranging from hearty soups and stews to curries and salads.
White Beans
This category includes several types, such as cannellini, navy, and great northern beans, all of which are excellent protein sources. Large white beans, or cannellini beans, provide over 17 grams of protein per cooked cup. Beyond protein, white beans are particularly rich in potassium, which is important for regulating blood pressure, and are a good source of fiber, iron, and folate. Their creamy texture makes them ideal for blending into dips, thickening soups, or adding to stews and salads.

Beyond Protein: The Broader Nutritional Benefits of Beans
While the protein content is a significant draw, the overall nutritional package of beans makes them a cornerstone of a healthy diet. They are packed with fiber, which supports healthy digestion, helps control blood sugar levels, and increases feelings of fullness, which can aid in weight management. Beans also provide a host of essential vitamins and minerals, including iron, folate, and magnesium, which play critical roles in red blood cell formation, DNA production, and nerve function.
Furthermore, many beans, such as black beans, contain powerful antioxidants that help combat inflammation and protect against cellular damage. The inclusion of beans in your diet has also been linked to better heart health and a reduced risk of chronic diseases.
Tips for Incorporating High-Protein Beans into Your Diet
- Start with simple swaps: Replace some or all of the ground meat in chili, tacos, or pasta sauce with lentils or black beans. You can also mix them to reduce meat consumption.
- Embrace versatile dips: Hummus is a classic, but you can also create creamy dips from blended cannellini or white beans. These are great with veggies or whole-grain pita bread.
- Boost your bowls and salads: Toss a handful of cooked and seasoned edamame into a grain bowl or mix chickpeas into a salad for a protein and fiber boost.
- Create meatless burgers: Mash pinto or black beans to form flavorful and satisfying veggie burger patties. They are an excellent, high-protein alternative to traditional burgers.
- Make them a snack: Roast seasoned chickpeas or edamame until crispy for a crunchy, healthy, and protein-packed snack. For a quick option, a snack pack of lupini beans also offers substantial protein.
