Lentils are edible seeds from the legume family, celebrated globally for their high nutrient content and versatility in the kitchen. As a primary protein source for vegetarians and vegans, understanding which lentils offer the most protein can help optimize dietary planning for muscle repair, weight management, and overall health. Different types of lentils offer varying protein levels, but generally, all are excellent sources of plant-based protein when cooked correctly.
Top varieties of protein-rich lentils
Not all lentils are created equal when it comes to protein content. While all lentils are nutritious, some varieties stand out for their exceptional protein density. Many of the highest-protein lentils are commonly used in South Asian cuisine, often referred to as 'dal'.
Horse Gram (Kulthi)
Considered one of the most protein-dense lentils, horse gram packs up to 30g of protein per 100g (dry weight). This powerful pulse is a staple in Ayurvedic diets and is also prized for its high fiber content.
Urad Dal (Black Gram)
Urad dal is another protein powerhouse, offering approximately 25–26 grams of protein per 100g (dry). When cooked, black gram is used in dishes like dal makhani, dosa, and idli, providing fiber and supporting digestion.
Masoor Dal (Red Lentils)
Red lentils are a quick-cooking variety known for their nutty and sweet flavor. A 100g serving (dry) can provide around 25g of protein, and they are also rich in iron and folate. As they cook, they break down into a creamy consistency, making them ideal for soups and curries.
Moong Dal (Green Gram)
Moong dal, or green gram, is versatile and easily digestible. Raw moong dal contains around 24g of protein per 100g. It is often used in soups, curries, and salads and is a good source of antioxidants.
Chana Dal (Split Bengal Gram)
Chana dal, or split chickpeas, has a nutty flavor and provides about 21–22g of protein per 100g (dry). It's a great source of fiber and minerals, helping to regulate blood sugar levels.
How to maximize protein from lentils
Simply eating lentils isn't enough; combining them with other ingredients can help create a more complete protein profile. Lentils are rich in the amino acid lysine but low in methionine. Conversely, many grains are higher in methionine but lower in lysine, so pairing them creates a complementary protein.
- Pair with grains: Combining lentils with rice or quinoa creates a complete protein profile, providing all the essential amino acids your body needs for muscle building and repair.
- Soak them: Soaking lentils, especially whole varieties, can improve digestibility and enhance nutrient absorption by reducing antinutrients like phytic acid.
- Add Vitamin C: Pairing lentils with foods rich in Vitamin C, like bell peppers or tomatoes, can significantly boost iron absorption, a mineral vital for energy and muscle function.
- Try different varieties: Experimenting with different types of lentils can provide a more varied nutritional intake. Whole, un-hulled varieties like green and brown lentils typically offer slightly more fiber.
Comparison Table: High-Protein Lentils (per 100g Dry Weight)

| Urad Dal (Black Gram) | 26g | Dal makhani, dosa batter | Creamy and thick |
| Masoor Dal (Red Lentil) | 25g | Curries, pureed soups, dals | Soft and mushy |
| Moong Dal (Green Gram) | 24g | Soups, salads, stews | Soft, easily digestible |
| Brown Lentils | 23g | Hearty soups, casseroles | Holds shape well, mild |
| French Green Lentils | 20.5g | Salads, side dishes | Firm and peppery |
Conclusion
Protein-rich lentils are an essential and cost-effective cornerstone of a healthy, balanced diet, especially for those seeking plant-based protein sources. With varieties like horse gram and urad dal offering exceptionally high protein content, lentils are a versatile ingredient for everything from creamy curries to hearty salads. By strategically pairing lentils with grains and incorporating proper cooking techniques, you can maximize their nutritional value and enjoy a host of health benefits, from improved digestion and heart health to better muscle maintenance. Integrating a variety of lentils into your meals is a simple and delicious way to boost your protein and nutrient intake.

How lentils compare to other protein sources
While lentils are an excellent source of protein for plant-based diets, they can also complement meat-inclusive diets, offering a healthier, low-fat alternative to other protein sources. For example, studies show that a half-cup of lentils contains more protein than an egg. Comparing lentils to animal-based proteins can reveal key differences in fat and fiber content, making lentils a favorable choice for heart health and digestion.
The comprehensive health benefits of protein-rich lentils
Beyond their protein content, lentils offer an array of health benefits. They are packed with dietary fiber, which promotes regular bowel movements and feeds beneficial gut bacteria. The low glycemic index of lentils helps manage blood sugar levels, making them a suitable food for preventing and managing diabetes. Additionally, the folate, potassium, and iron found in lentils are crucial for supporting heart health and preventing anemia. The richness of polyphenols also gives lentils potent antioxidant and anti-inflammatory properties.
