Lentils are a staple in nutritious diets around the world, celebrated for their high fiber content, rich mineral profile, and excellent protein levels. As a top-tier plant-based protein source, they are a versatile and affordable alternative to meat, making them a cornerstone of vegetarian and vegan cooking. However, not all lentils are created equal when it comes to their protein power. For those specifically seeking to maximize their protein intake, understanding the differences between lentil varieties is key.
The Protein Champion: Horse Gram (Kulthi)
According to nutritional data, the undisputed champion for protein content among lentils is Horse Gram, also known as Kulthi. A lesser-known but highly nutritious legume, Horse Gram contains an impressive 30 grams of protein per 100 grams (dry weight). This makes it one of the most protein-dense pulses available and a fantastic option for anyone looking to increase their plant-based protein intake. In addition to protein, Horse Gram is rich in fiber, iron, and calcium, and has been linked to weight loss benefits due to its high satiety. It is most commonly used in traditional Indian cuisine, lending itself well to soups, dals, and stews.
Top Protein Contenders
While Horse Gram holds the top spot, several other popular lentil varieties offer significant protein content, each with its own unique flavor and texture profile.
Urad Dal (Black Gram)
Urad Dal, or black gram, is another high-protein option widely used in South Asian dishes. It boasts approximately 26 grams of protein per 100 grams (dry weight) and is often used to make dense, creamy dals like Dal Makhani or batters for dosas and idlis. Beyond its protein, urad dal is a good source of calcium and iron, aiding in bone health and muscle repair.
Beluga Lentils (Black Lentils)
Nicknamed for their resemblance to Beluga caviar, these tiny, glossy black lentils are a favorite among chefs for their rich, earthy flavor and ability to hold their shape exceptionally well after cooking. Beluga lentils contain about 24 grams of protein per 100 grams (dry weight) and are packed with antioxidants, making them a superfood for heart health. They are perfect for salads, side dishes, and veggie burgers.
Red Lentils (Masoor Dal)
Red lentils cook very quickly and break down easily, creating a creamy, thick consistency ideal for soups, curries, and purees. With around 25 grams of protein per 100 grams (dry weight), they are a nutritious and easily digestible choice. Red lentils are also rich in iron and folate, which support blood health.
Brown Lentils
Brown lentils are a versatile and common type, retaining their shape well during cooking and offering a hearty, earthy flavor. They provide approximately 23 grams of protein per 100 grams (raw) and are excellent for stews, salads, and side dishes.
High-Protein Lentil Comparison Table
To provide a clearer picture, here is a comparison of the protein content and characteristics of various lentils based on dry weight measurements where specified.

| Green Lentils | 20.5g | Holds shape well, firm texture. | Salads, side dishes. |
Maximizing Protein Absorption from Lentils
For optimal nutrient uptake, there are several preparation methods you can employ to get the most out of your lentils:
- Pair with whole grains: Lentils are rich in the amino acid lysine but low in methionine. Whole grains like rice, quinoa, and wheat have the opposite profile. Pairing them together creates a 'complete protein' with all essential amino acids, though it's important to note that the body uses a pool of amino acids throughout the day, so they don't need to be consumed in the exact same meal.
- Soaking or sprouting: Soaking lentils can improve digestibility and increase nutrient bioavailability. Sprouting, particularly for mung beans and chana dal, increases the availability of certain nutrients.
- Combine with Vitamin C: Including vitamin C-rich foods like tomatoes, bell peppers, or citrus juice can enhance iron absorption, another vital nutrient found in high quantities in lentils.
- Cook with healthy fats: While lentils are low in fat, cooking them with healthy oils like olive oil can aid in the absorption of certain fat-soluble vitamins and add richness.
Beyond Protein: Lentils' Additional Benefits
Lentils are more than just a protein source; they are a nutritional powerhouse offering numerous health advantages:
- Fiber: Rich in both soluble and insoluble fiber, lentils promote digestive health, help regulate blood sugar levels, and increase satiety, which is beneficial for weight management.
- Heart Health: Regular consumption of lentils is associated with reduced cholesterol levels and a lower risk of heart disease. Their fiber and potassium content help to manage blood pressure.
- Antioxidants: Black lentils, in particular, contain anthocyanins, powerful antioxidants with anti-inflammatory properties. Lentils, in general, have a high antioxidant capacity, which helps fight cell damage.
- Minerals and Vitamins: Lentils are excellent sources of essential nutrients such as iron, folate, magnesium, and potassium. Folate is especially important for cell growth and during pregnancy.
Easy Ways to Add High-Protein Lentils to Your Diet
Incorporating more lentils into your weekly meals is simple and delicious. Their versatility means they can be used in a wide variety of dishes, from stews to salads. Here are a few ideas:
- Hearty Lentil Soup: Use brown or green lentils for a thick, comforting soup base. Add vegetables, herbs, and spices.
- Beluga Lentil Salad: Combine cooked and cooled beluga lentils with chopped vegetables like cucumbers and tomatoes, a light vinaigrette, and fresh herbs like parsley and mint. Their firm texture makes them perfect for this.
- Lentil Bolognese: Red lentils are perfect for a creamy, meat-free pasta sauce. As they cook down, they create a rich, thick texture that coats pasta beautifully.
- Veggie Burgers: Mash cooked brown or black lentils with breadcrumbs, spices, and finely diced onion for a protein-packed patty.
- Indian Dal: Prepare a classic Indian dal with urad or horse gram, simmering them with traditional spices for a flavorful and filling meal.
