What is Horse Gram?
Horse gram, known scientifically as Macrotyloma uniflorum, is a lesser-known but highly nutritious pulse native to Southeast Asia and tropical Africa. It is also referred to by regional names such as kulthi in Hindi, kollu in Tamil, and ulavalu in Telugu. Historically, it was a staple food for both humans and livestock, with archaeological evidence pointing to its consumption as early as 2000 BC in ancient India. The seeds are small, oval, and have a reddish-brown or black color, and they are notably hard, requiring extensive soaking and cooking.
Horse gram is well-regarded in Ayurvedic medicine for its warming properties and therapeutic potential. It is particularly valued for its high iron, calcium, and protein content, and for being rich in dietary fiber. Its low fat content and high levels of resistant starch have made it a candidate for weight management diets and diabetes control.
What is Chickpea?
Chickpea, or Cicer arietinum, is one of the most widely cultivated and consumed legumes globally. It is also known by many other names, including garbanzo bean, ceci bean, and Bengal gram. The two main types are:
- Kabuli: The larger, lighter-colored variety typically found in Western cuisine, used for dishes like hummus and salads.
- Desi (Kala Chana): A smaller, darker, and tougher chickpea with a thicker seed coat, commonly used in Indian curries and snacks. The name 'Bengal gram' is correctly applied to this desi variety of chickpea, not horse gram.
Chickpeas are a powerhouse of nutrients, providing substantial amounts of protein, fiber, and various minerals like folate, iron, and zinc. Their versatility is evident in their use across diverse cuisines, from Middle Eastern dips to Indian curries and American snacks.
Key Differences Between Horse Gram and Chickpea
Botanical and Physical Differences
Botanically, horse gram and chickpea are distinct species, belonging to different genera within the same plant family (Fabaceae). The physical differences are easily observable.
- Size and Shape: Horse gram seeds are small, oval, and flattened, while chickpeas are larger, round, and irregular in shape.
- Color: Horse gram is typically reddish-brown to black, whereas chickpeas vary from white/cream (Kabuli) to dark brown/black (Desi).
- Seed Coat: Horse gram has a particularly tough seed coat, contributing to its longer cooking time, while chickpeas have a thinner seed coat.
Nutritional Differences
While both are excellent sources of plant-based nutrition, their macro and micronutrient profiles show clear distinctions.
Nutritional Comparison per 100g of Flour (Approximate):
- Fat Content: Chickpea flour has a higher fat content (approx. 4.8%) compared to horse gram flour (approx. 1.4%).
- Dietary Fiber: Horse gram flour contains a higher amount of total dietary fiber (16.3%) compared to chickpea flour (14.8%).
- Carbohydrates: Horse gram has a higher carbohydrate content than chickpea.
- Antinutrients: The types and quantities of antinutritional compounds like polyphenols and oligosaccharides vary, contributing to different functional properties.
Culinary Differences
Their physical and nutritional characteristics lead to different culinary applications and preparation methods.
- Cooking Time: Due to its hard seed coat, horse gram typically requires more soaking and a longer cooking time than chickpeas.
- Texture and Taste: Cooked horse gram retains a firmer, slightly crunchy texture, even when fully cooked. Chickpeas become creamy and soft when cooked, making them ideal for purees like hummus. The taste of horse gram is earthier and more robust.
- Best Uses: Horse gram is often used in warming soups (rasam), curries (kulith pithla), and sprouts. Chickpeas are incredibly versatile, used in salads, curries, stews, and ground into flour (besan) for batters and sweets.

Health Benefits: A Closer Look
Both legumes offer impressive health benefits, but some are more specific to each.
Horse Gram Benefits
- Weight Management: Its high fiber content promotes satiety and can aid in weight loss.
- Kidney Health: Traditional medicine uses horse gram to help dissolve kidney stones and improve liver function.
- Anti-inflammatory: It possesses anti-inflammatory properties that can boost the immune system.
- Diabetes Control: Studies suggest it can slow the digestion of carbohydrates, which helps regulate blood sugar levels.
Chickpea Benefits
- Heart Health: Chickpeas contain soluble fiber and compounds that help lower LDL ("bad") cholesterol, reducing the risk of heart disease.
- Blood Sugar Regulation: With a low glycemic index and slow-digesting starches, chickpeas help manage blood sugar levels.
- Digestive Health: High dietary fiber, particularly soluble fiber, promotes regular bowel movements and gut health.
- Cancer Prevention: Studies show that the short-chain fatty acid butyrate, produced when chickpeas are consumed, may help combat colorectal cancer.
Can You Substitute Horse Gram for Chickpea?
While it is possible to use one in place of the other in certain applications, it is not a perfect one-to-one swap due to significant differences in texture, flavor, and cooking time. If substituting horse gram for chickpea in a dish, you must be prepared for a much longer cooking process and a firmer, earthier result. Conversely, substituting chickpea for horse gram will result in a much softer texture and a milder flavor, which may not suit traditional recipes like horse gram rasam.
Conclusion: Not the Same, but Both Valuable
Ultimately, the question 'Are horse gram and chickpea the same?' has a clear answer: no. Horse gram (Macrotyloma uniflorum) and chickpea (Cicer arietinum) are two distinct, albeit related, legumes. The confusion often arises from the shared use of the word 'gram' and the existence of 'Bengal gram' as a chickpea variety. Both pulses bring unique flavors, textures, and health benefits to the table and are valuable additions to a healthy diet. Understanding their individual properties allows for more informed and intentional cooking, ensuring you can harness the best of each legume in your culinary endeavors.
