Lentils vs. Grams: Demystifying the Distinction
For many home cooks and food enthusiasts, the terms 'lentils,' 'grams,' and 'dal' are used interchangeably, leading to widespread confusion. However, understanding the precise differences can elevate your cooking and nutritional knowledge. While both lentils and various grams fall under the broad category of pulses (the edible, dried seeds of legume plants), they are distinct in their botanical origin, appearance, and culinary uses.
What Exactly Are Lentils?
Lentils ($Lens culinaris$) are small, lens-shaped, dried seeds that grow in pods, typically with two seeds per pod. Known for their quick cooking time and wide variety, they are a staple in many cuisines worldwide. Lentils are classified by their color and size, and varieties can include:
- Brown Lentils: The most common variety, with a mild, earthy flavor. They hold their shape well when cooked but can become mushy if overcooked, making them perfect for soups and stews.
- Green Lentils: Have a nutty, peppery flavor and maintain their shape, making them ideal for salads or side dishes.
- Red Lentils: These are hulled and split lentils that cook very quickly and soften into a creamy consistency. They are essential for many Indian dals and purees.
- Puy or French Green Lentils: A specific variety known for its peppery flavor and firm texture, often used in salads.
What Defines 'Gram'?
The term 'gram' is more ambiguous and often refers to a specific type of pulse, not a universal one. It is particularly prevalent in Indian and South Asian cuisine, where different pulses are referred to by a variety of names. A 'gram' is typically a larger, rounder pulse than a lentil, and it may be used whole, split with the hull on (like 'kaala chana' or black gram), or split with the hull removed (like 'chana dal' or split Bengal gram). Examples of 'grams' include:
- Bengal Gram (Chana): A type of chickpea used both whole and split. Split Bengal gram is known as 'chana dal'.
- Black Gram (Urad): A small, black matpe bean often used in Indian cooking.
- Green Gram (Moong): The mung bean, used in various forms including whole, split, and hulled (moong dal).
- Horse Gram: A lesser-known legume with a higher protein content.
Comparison Table: Lentils vs. Grams
| Feature | Lentils ($Lens culinaris$) | Grams (e.g., Chickpea, Black Gram) |
|---|---|---|
| Botanical Name | $Lens culinaris$ | Varies, e.g., $Cicer arietinum$ (Bengal Gram), $Vigna mungo$ (Black Gram) |
| Shape | Small, flat, and lens-shaped | Larger, rounder, often irregularly textured |
| Cooking Time | Generally cooks faster, especially red lentils | Can vary; many require longer soaking and cooking times |
| Flavor Profile | Mild, earthy, nutty, or peppery depending on variety | Earthy, nutty, sometimes slightly more robust |
| Texture | Can hold shape or become creamy when cooked | Often retain a firmer, chewier texture |
| Common Use | Soups, salads, stews, purees | Dals, curries, ground into flour (besan), side dishes |
Nutritional Differences and Similarities
Both lentils and grams are nutritional powerhouses, but their compositions differ slightly. As members of the pulse family, they are both excellent sources of plant-based protein, dietary fiber, and essential minerals like iron, potassium, and magnesium.
- Protein: While both are high in protein, the exact content can vary between different types. Lentils generally offer around 18g of protein per cooked cup, while some grams like black gram can have a slightly higher protein concentration.
- Fiber: Both are rich in fiber, which is crucial for digestive health and can help manage blood sugar levels.
- Nutrient Absorption: Pulses contain phytic acid, which can inhibit the absorption of some minerals. Soaking and cooking, as is typical with these ingredients, significantly reduces this effect, enhancing nutrient bioavailability.
Culinary Applications
The culinary use of lentils and grams is where their distinct characteristics truly shine. Lentils, with their quick-cooking nature and ability to either hold their shape or break down, are incredibly versatile. They can be the star of a hearty lentil soup, the base of a creamy Indian dal, or a robust addition to a salad.
Grams, on the other hand, often serve different purposes. Chana dal (split Bengal gram) is used in thick, satisfying dals and is also ground into besan, or gram flour, which is a key ingredient in many South Asian snacks and flatbreads. Whole chickpeas (also a type of gram) are used in curries, stews, and hummus. The longer cooking time and firmer texture of many grams make them well-suited for dishes that require a heartier, more substantial bite.
Conclusion: The Difference Is in the Details
To put it simply, while all lentils are pulses, and 'grams' often refer to other pulses, they are not the same thing. The distinction lies in their physical form, botanical origin, and culinary behavior. Lentils are the small, lens-shaped seeds, while grams typically refer to larger, rounder pulses like chickpeas or mung beans, especially in South Asian contexts. Both are incredibly healthy and versatile components of a plant-based diet, but knowing the difference allows for more precise and effective cooking. The next time you visit a grocery store, you can confidently distinguish between a bag of red lentils and a container of chana dal, ensuring your dish comes out just right.

Frequently Asked Questions About Lentils and Grams
What is a pulse? A pulse is the edible, dried seed of a legume plant. The term pulse refers only to the dried seed, while the broader term 'legume' includes the entire plant, including fresh peas and fresh beans.
Why are they so often confused? Both lentils and grams are common pulses used in similar cuisines, particularly in India. In some contexts, the word 'gram' is used generically for pulses, adding to the confusion.
Do lentils or grams need to be soaked? Many varieties of lentils, especially split ones like red lentils, do not require soaking and cook quickly. Larger, firmer grams like chickpeas generally benefit from an overnight soak to reduce cooking time and aid digestibility.
Can I substitute lentils for grams in a recipe? It depends on the recipe. For a hearty soup or stew, you might be able to swap brown lentils for a type of gram. However, for a dish where texture is critical, such as a creamy dal made with red lentils, a gram may not work as it won't break down in the same way.
What is 'dal'? 'Dal' is a term used in Indian cuisine for the dried, split pulses (including lentils and grams) and also for the thick stew or curry made from them.
Which is healthier, lentils or grams? Both are incredibly healthy, being rich in protein, fiber, and various minerals. The 'healthier' option depends on the specific nutritional needs and culinary goals. Lentils and grams complement each other well as part of a balanced diet.
Why are some lentils called 'grams' in recipes? In South Asian terminology, specific lentils may be referred to as 'gram,' such as 'moong gram' for mung beans. This is a cultural and regional naming convention and is why it's important to understand the specific type of seed being used.
Are lentils and grams gluten-free? Yes, as they are naturally occurring legumes, both lentils and grams are gluten-free, making them excellent choices for those with celiac disease or gluten sensitivities.
Can lentils be used to make flour like gram flour? While lentils can be ground into flour, 'gram flour' (besan) is specifically made from chickpeas (Bengal gram). The flavors and properties of the resulting flour will differ.
Is there a difference between dried peas and grams? Yes. Dried peas, such as split green or yellow peas, are a separate type of pulse, though often used similarly to some grams. Grams, as mentioned, usually refer to the chickpea or black matpe bean family in a South Asian context.
