Toor Dal
Toor dal is a split yellow pigeon pea legume widely used in South Asian cuisine. It is high in protein and fiber, with a low to moderate glycemic impact and compounds that may modestly affect mineral absorption.
Also known as: pigeon peas, arhar dal, split pigeon peas, Arhar dal, Pigeon pea dal, Tur dal, Cajanus cajan

Toor dal, also called arhar dal or pigeon pea dal, is the hulled and split seed of Cajanus cajan. It is a staple legume in Indian, Pakistani, and other South Asian cuisines, typically cooked into a thick soup or stew (dal) and served with rice or bread. The ingredient is available dried whole or pre-split, and sometimes roasted or oiled.
Toor dal provides approximately 8–11 grams of protein per cooked cup, along with a substantial amount of fiber, making it a significant plant-based protein and carbohydrate source. Like other legumes, it contains tannins and phytates—compounds that can modestly reduce bioavailability of iron, zinc, and calcium when consumed regularly in large quantities. Soaking and cooking substantially lower phytate levels. Toor dal has a low to moderate glycemic index (published estimates range from approximately 22–42 depending on preparation) and does not spike blood glucose dramatically.
Fiber and Digestive Effects
The soluble and insoluble fiber in toor dal supports digestive transit and provides substrate for beneficial gut bacteria. In individuals unaccustomed to high-legume intake, consumption may cause temporary bloating or gas; this typically resolves within weeks as gut microbiota adapt. Soaking and rinsing dried dal, and thorough cooking, reduce oligosaccharides responsible for gas production.
Tolerance and Portion Guidance
Toor dal is well tolerated by most populations and is not a common allergen, though rare legume sensitivities exist. People with kidney disease or those taking certain medications should discuss legume intake with a healthcare provider. No inherent upper limit exists; typical servings are 1/2 to 1 cup cooked dal per meal. Individuals introducing legumes should increase intake gradually over 2–4 weeks to minimize digestive discomfort.
Frequently Asked Questions
Does toor dal cause gas or bloating?
Toor dal contains oligosaccharides that some people find difficult to digest, which can cause temporary bloating or gas. Soaking dried dal for several hours before cooking, rinsing well, and cooking thoroughly reduces these compounds. Most people adapt within 2–4 weeks of regular consumption as their gut microbiota adjust.
Is toor dal high in protein?
Yes. Cooked toor dal provides approximately 8–11 grams of protein per cup, making it a substantial plant-based protein source. It is particularly valuable in vegetarian and vegan diets as a substantial plant-based protein source.
Does toor dal affect mineral absorption?
Toor dal contains phytates and tannins that can modestly reduce bioavailability of iron, zinc, and calcium. Soaking and cooking significantly reduce phytate levels. For most people eating a varied diet, this has minimal practical impact; those at risk for mineral deficiency should maintain diverse food sources and consult a healthcare provider.
Is toor dal suitable for people with diabetes?
Toor dal has a low to moderate glycemic index (published estimates range from approximately 22–42 depending on preparation) and is relatively low in simple sugars, making it a reasonable choice for blood-sugar management when portion-controlled and combined with vegetables or whole grains. Individual responses vary; those managing diabetes should monitor their personal responses and work with their healthcare team.
