Understanding the Potential Downsides of a Nutritious Legume
Horse gram, also known as Kulthi dal, is a nutrient-dense legume widely used in South Asian cuisine and traditional medicine systems like Ayurveda. It is celebrated for its high protein, fiber, and mineral content, and is often consumed as a soup to aid in weight loss, digestion, and to manage conditions like kidney stones. However, despite its benefits, it is crucial to understand that consuming horse gram soup can have potential side effects, particularly if consumed in excess or improperly prepared.
Common Digestive Issues
One of the most frequently reported side effects of horse gram soup is digestive discomfort, which primarily manifests as gas and bloating.
Bloating and Flatulence
Horse gram contains certain complex carbohydrates known as raffinose oligosaccharides. Unlike other types of carbs, the human body cannot easily digest raffinose. As a result, these carbohydrates travel to the large intestine, where they are fermented by gut bacteria. This fermentation process produces gas, leading to bloating and flatulence, especially when the soup is consumed in large quantities. Soaking and sprouting the beans before cooking can significantly reduce the concentration of these gas-producing compounds.
Poor Nutrient Absorption
Like many legumes, horse gram contains antinutrients, such as phytic acid. Phytic acid is a compound that can bind to essential minerals like iron, zinc, and calcium, thereby reducing their absorption by the body. While this is a concern, proper preparation methods like soaking and cooking are very effective at decreasing the antinutrient content. For instance, soaking horse gram overnight or sprouting it prior to making soup can improve the bioavailability of its nutrients.
Considerations Based on Ayurvedic Principles
Ayurveda classifies foods based on their thermal energy, and horse gram is considered a food that generates heat within the body.
Heat-Inducing Properties
As per Ayurvedic tradition, horse gram, particularly in a cooked form like soup, produces significant body heat. While this can be beneficial in cold weather, overconsumption can lead to an excess of Pitta dosha, potentially causing issues like a burning sensation during urination or digestive discomfort. To balance this effect, horse gram is often paired with cooling ingredients like buttermilk, ash gourd, or cumin seeds.
Specific Health Condition Concerns
For individuals with pre-existing health conditions, horse gram soup may pose additional risks and should be consumed with caution and under medical supervision.
Gout and High Uric Acid
Horse gram contains purines, which are natural compounds that break down into uric acid in the body. Excessive intake of purine-rich foods can elevate uric acid levels, which can precipitate gout attacks and joint pain in susceptible individuals. Therefore, those with a history of gout or high uric acid should limit their consumption of horse gram.
Pregnancy and Women's Health
Some traditional health practices advise pregnant women to avoid horse gram due to its heat-generating properties and potential emmenagogue effects (stimulating or increasing menstrual flow). While research is limited, caution is generally recommended, and pregnant or breastfeeding women should consult a healthcare provider before including it in their diet.
Kidney Stone Risk
Ironically, while horse gram is often recommended in Ayurveda for its diuretic properties to help dissolve kidney stones, its high oxalate content can be problematic for some individuals. Oxalates can bind with calcium to form calcium oxalate stones, the most common type of kidney stone. Patients with a history of calcium oxalate stones should be cautious and seek medical advice before consuming it regularly.
Allergic Reactions
Although rare, some individuals may have an allergic reaction to horse gram, as they do to other legumes. Symptoms could include itching, swelling, or difficulty breathing. Any adverse reaction warrants immediate medical attention and cessation of consumption.
How to Minimize Side Effects of Horse Gram Soup
- Soak Before Cooking: Soaking horse gram seeds for at least 8-10 hours, preferably overnight, helps reduce the levels of phytic acid and oligosaccharides that cause gas.
- Sprout for Better Digestion: Sprouting horse gram further increases its nutritional value and significantly reduces antinutrient content, making it easier to digest.
- Cook Thoroughly: Ensure the seeds are cooked well until soft. Thorough cooking breaks down complex sugars and proteins, aiding digestion.
- Start with Small Portions: Introduce horse gram gradually into your diet to allow your digestive system to adjust, and always consume it in moderation.
- Balance with Cooling Foods: To counteract its heat-inducing properties, particularly when making soup, pair it with cooling ingredients or consume it alongside foods like buttermilk or yogurt.

| Feature | Horse Gram Soup | Lentil (Dal) Soup | Mung Bean (Moong) Soup |
|---|---|---|---|
| Digestibility | Moderate; can cause gas if not prepared properly. | High; generally easy to digest. | Very High; considered a cooling food and highly digestible. |
| Heat-Inducing Effect | High; considered warming in Ayurveda. | Neutral to mildly warming. | Neutral to cooling. |
| Antinutrient Level | Contains phytic acid, reduced by soaking. | Contains phytic acid, reduced by soaking. | Lower antinutrient content, easier on the digestive system. |
| Best For | Warming during cold weather, boosting metabolism. | General nutrition, all-purpose meal. | Balancing body heat, easy digestion. |
Conclusion
While horse gram soup offers a range of impressive health benefits, from promoting weight loss to supporting kidney health, it is not without its potential drawbacks. The side effects, including digestive issues like bloating and flatulence, increased body heat, and interactions with conditions like gout, are primarily linked to improper preparation and overconsumption. By adopting simple yet effective preparation techniques—such as soaking and thoroughly cooking the seeds—and consuming the soup in moderation, most individuals can enjoy its nutritional advantages while significantly mitigating potential risks. As with any significant dietary change, it is wise to consult a healthcare professional, especially if you have pre-existing health conditions like kidney disease or are pregnant.
