What is Horsegram (Kulthi)?
Also known as kulthi in Hindi and kollu in Tamil, horsegram is a type of pulse or legume belonging to the Fabaceae family. The seeds are small, flattened, and come in various shades of red, brown, or black. Historically, it was a staple fodder for horses, which is how it earned its name, but it is now widely recognized for its significant benefits for human health. It is particularly resilient, thriving in dry, arid regions where other crops might fail, making it a sustainable and valuable food source for resource-poor communities.
Nutritional Profile of Horsegram
Horsegram is a nutritional powerhouse, packed with a wide array of macronutrients and micronutrients that contribute to its many health benefits. A typical 100-gram serving of horsegram provides:
- Protein: Approximately 22 grams, making it an excellent plant-based protein source for vegetarians and vegans.
- Carbohydrates: Roughly 57 grams, with a significant portion consisting of complex carbohydrates and resistant starch, which promotes stable blood sugar levels.
- Fiber: Around 5 grams, aiding in digestion and promoting a feeling of fullness.
- Minerals: It boasts the highest calcium content among all pulses (287 mg), along with ample iron (7 mg), phosphorus (311 mg), and molybdenum.
- Vitamins: It contains B vitamins, including thiamine and niacin, and is also a source of vitamin C.
- Antioxidants: Rich in polyphenols and flavonoids, which combat oxidative stress and protect against chronic diseases.
Scientifically-Backed Benefits of Horsegram
Numerous studies, including both animal and preliminary human research, support the traditional medicinal uses of horsegram. Its potent bioactive compounds, such as phenolic acids, phytic acid, and flavonoids, are responsible for its therapeutic effects.
Aids in Weight Management
For those seeking to manage their weight, horsegram is a powerful ally. Its high fiber and protein content contribute to a feeling of satiety, helping to reduce overall calorie intake. The presence of phenols in horsegram also helps in attacking and reducing fatty tissue. Some animal studies have shown that horsegram extract can protect against weight gain and reduce body weight in rats. Its low-fat, high-fiber composition makes it an ideal addition to a weight-loss diet.
Supports Diabetes Management
Horsegram has a low glycemic index, meaning it releases glucose slowly into the bloodstream, preventing sudden spikes in blood sugar levels. Raw, unprocessed horsegram seeds have been shown to slow down carbohydrate digestion and reduce insulin resistance, making it particularly beneficial for individuals with Type 2 diabetes. A study by the Indian Institute of Chemical Technology scientifically validated its anti-hyperglycemic properties.
Promotes Heart Health
The rich antioxidant profile of horsegram, including polyphenols and flavonoids, helps protect against the oxidative damage caused by free radicals that can lead to heart disease. Furthermore, research suggests that horsegram may help lower LDL (bad) cholesterol and triglyceride levels, while its low sodium and high potassium content help manage blood pressure. Regular consumption of fiber-rich legumes like horsegram is associated with a reduced risk of heart disease.
Helps Prevent and Manage Kidney Stones
In traditional medicine, horsegram is renowned for its ability to help with kidney stones. Its potent diuretic properties increase urine flow, which helps flush out small calculi. Some preliminary studies indicate that horsegram may inhibit the formation of calcium oxalate crystals, the most common component of kidney stones. The hot-natured decoction is believed to help dissolve stones in their early stages.
Other Notable Benefits
Beyond its major health impacts, horsegram offers several other advantages:
- Digestive Health: The high fiber content promotes regular bowel movements, preventing constipation, bloating, and other digestive issues.
- Respiratory Relief: A traditional remedy involves using horsegram to treat coughs, colds, and respiratory issues by helping to expel phlegm and clear congestion.
- Bone Health: With the highest calcium content among pulses, along with phosphorus, horsegram is excellent for strengthening bones and preventing conditions like osteoporosis and arthritis.
- Anemia Prevention: Its high iron content is crucial for the production of hemoglobin and can help combat anemia, especially important during pregnancy.
Important Considerations and Preparation
While highly beneficial, horsegram contains some anti-nutritional factors, like phytic acid and tannins, which can inhibit mineral absorption. The good news is that proper preparation can significantly reduce these compounds. Soaking, sprouting, or cooking horsegram before consumption is essential. Excessive consumption may also cause gas and bloating due to raffinose oligosaccharides, and its heat-generating property means it should be consumed in moderation, especially by pregnant women.
Comparison of Preparation Methods
| Feature | Soaking | Sprouting | Cooking/Boasting | Roasting |

Conclusion
Horsegram is a potent and nutrient-dense legume with a long history of use in traditional medicine. Its high levels of protein, fiber, antioxidants, and minerals make it a valuable food for addressing a range of health concerns, including weight management, diabetes, heart health, and kidney stones. While proper preparation is key to enhancing its digestibility and nutrient absorption, incorporating this versatile and resilient pulse into your diet can provide significant and lasting health benefits. For those looking for an economical, eco-friendly, and powerful addition to their nutrition regimen, horsegram is an excellent choice.
