Understanding the Heating Property of Kollu (Horse Gram)
Kollu, or horse gram, is a significant legume in South Indian and Ayurvedic traditions. Its reputation as a 'heating' food, often used in colder months, is supported by traditional medicine and scientific understanding.
The Ayurvedic and Siddha Perspective
Ayurveda classifies Kollu as 'ushna veerya,' meaning it has hot potency. It is believed to balance Vata and Kapha doshas and potentially increase Pitta dosha. This heating effect is thought to help with bodily functions, including clearing phlegm.
Scientific Explanation: Thermogenesis and Metabolism
Modern nutrition attributes Kollu's warming effect to its high protein content. The body expends more energy to digest protein, a process called the 'thermic effect of food,' which generates warmth and boosts metabolism. This also contributes to its role in weight management.
Health Benefits of Kollu Beyond Its Heating Effect
Kollu is considered a superfood due to its numerous health benefits:
- Weight Management: High protein and fiber promote satiety and aid in weight loss.
- Kidney Health: Traditionally used to help dissolve kidney stones and as a diuretic.
- Digestive Health: Fiber supports bowel movements, and soaking or sprouting improves digestibility.
- Blood Sugar Control: Its low glycemic index is beneficial for managing blood sugar.
- Immunity Booster: Rich in antioxidants and minerals, it strengthens the immune system.
- Menstrual Health: Iron content can assist with irregular periods and low hemoglobin.

Conclusion
The belief that Kollu generates body heat is supported by both traditional and scientific evidence. Its high protein and fiber content lead to a thermogenic effect, making it a valuable warming food, especially in winter. However, consuming Kollu in moderation and preparing it correctly through soaking or pairing with cooling ingredients is essential to balance its properties.
