10 benefits of toor dal (and its side effects)

Protein: 21.7 g per 100 g, the lysine partner cereals miss

Protein is the headline of the dal: IFCT 2017 prints 21.7 g in every 100 g of raw toor, and a cooked katori made from 30 g of dry dal carries about 6.5 g. What makes pulse protein valuable is not just the amount but the kind. The Dietary Guidelines lay out the chemistry: cereals run lower in lysine and higher in the sulphur amino acids, methionine and cysteine, while pulses run the other way around, so each food supplies what the other is short of. Mix cereal and pulse at 3:1 by raw weight and, in the guidelines' arithmetic, the two together can meet the need for each essential amino acid. In practice that pair is the everyday dal-chawal, or the toor dal khichdi that cooks both in one pot.

Fibre: 9.1 g per 100 g for a slower release and a settled appetite

Toor's 9.06 g of fibre per 100 g is the second number worth knowing, and a katori carries about 2.7 g. The guidelines credit dietary fibre with slowing how fast carbohydrate and fat are absorbed, and with the satiety that follows. The fibre travels with the carbohydrate rather than against it, and among the three everyday dals toor's sits close to moong dal's 9.4 g, with chana dal ahead at 15.2 g.

Low fat: 1.56 g per 100 g, so the katori stays lean

Fat is where toor separates from chana dal: 1.56 g per 100 g is about a third of chana dal's 5.31 g, and moong dal alone is leaner at 1.4 g. Cooked, the fat per katori is about 0.5 g, and that is before the tempering; every teaspoon of oil or ghee added in the tadka sits on top of that number, so the lean katori is the one with a light hand on the tarka.

Satiety: a katori at about 99 kcal goes further than it looks

Put the fibre and the low fat together and the weight side writes itself: one katori of cooked dal, from 30 g of dry dal, comes to about 99 kcal before any tadka. The guidelines put pulses among the fibre-rich foods that lift satiety and steady blood glucose, insulin, cholesterol and triglycerides, and they add that pulses help maintain weight. The portion-by-portion reading is on toor dal for weight loss.

Low glycemic index: 20, with the whole-pea asterisk

Pigeon pea lands in the low band of the glycemic index tables: the four tests on record average 20 and spread from 7 to 43, and the database counts 55 and below as low. The asterisk matters: every one of those tests used whole pigeon peas, none used the split dal Indian kitchens cook, and none was run in India, so the number is a careful guide rather than a measurement of your katori. The meal around the dal decides the rest, because rice and roti bring their own carbohydrate, and the full portion logic is on toor dal for diabetes.

Iron: 3.9 mg per 100 g, paired with vitamin C in the same meal

Toor's iron is 3.9 mg per 100 g, about 1.2 mg in a katori. The guidelines say vitamin C rich fruits, guava and citrus among them, improve iron absorption from plant foods when eaten as part of the same meal. Tea pulls the opposite way: it binds dietary iron and makes it unavailable, which is the guidelines' reason for keeping a cup an hour clear of any meal. A squeeze of lemon over the dal is the habit that costs nothing.

Folate: 108 mcg per 100 g, the B vitamin on the legume list

Folate reads 108 mcg per 100 g, and a katori brings about 32 mcg. The Dietary Guidelines put legumes, along with green leafy vegetables and nuts, on the list of foods that carry folic acid, and toor is that legume on most Indian plates. It is the B vitamin the body draws on for red cell formation, and it arrives in the dal already partnered with iron, the two nutrients a plate of dal-and-rice quietly delivers every day.

Potassium: 1395 mg per 100 g against 18 mg of sodium

Per 100 g the dal carries 1395 mg of potassium, and only 18 mg of sodium beside it. The guidelines pair the two minerals: sodium and potassium together keep water and fluid balance and electrolyte equilibrium, and the guidelines' advice is that sodium intake needs balancing with potassium intake; beans and lentils sit on the guidelines' list of good potassium sources. That is nearly eighty times more potassium than sodium in the raw dal, before any salt goes into the pot.

Magnesium, calcium and zinc: the minerals that run the body's checks

Toor also carries 119 mg of magnesium, 71.7 mg of calcium and 2.6 mg of zinc per 100 g. The guidelines describe what this mineral family does: nerve signals, the body's acid-base and fluid balance, enzyme and hormone activity, and the blood-clotting processes all draw on them. Calcium in particular is a quiet strength of toor among the everyday dals, since its 71.7 mg per 100 g beats moong dal's 43.1 mg and chana dal's 46.3 mg. Cooking helps the minerals along, because the guidelines note that phytic acid in legumes, which holds them back, is reduced to a great extent by boiling or pressure cooking.

The longer run: what pulse studies report

A 2014 review of pulse research (Mudryj, Yu and Aukema) reports that pulse consumption improves serum lipid profiles and positively affects several other cardiovascular risk factors, naming blood pressure, platelet activity and inflammation. The review's own caveat: long-term randomized controlled trials are needed to demonstrate the direct effects of pulses on these diseases. The honest reading: toor earns its place as an everyday food.

The side-effect list for toor dal is short and mostly about digestion. Two notes deserve honest answers: gas, and the uric-acid question that follows purine-rich foods. This is also where the toor dal benefits and side effects balance gets personal, because both notes sit heavier on some people than on others.

Gas: the sugars the small intestine passes on

Toor dal can cause gas, as pulses generally do. The chemistry, from a 2019 review of pulse tolerance in Current Opinion in Food Science: the dal carries galacto-oligosaccharides, raffinose, stachyose and verbascose, sugars the small intestine leaves undigested, so they reach the colon to ferment, and the gas is the by-product. Two hedges follow: the review says the explanation itself has recently been questioned, and its practical note is that flatulence mostly fades within a few weeks when the pulses stay in the diet. If the dal stays in the diet, the discomfort usually settles on its own.

Uric acid: what the studies actually report

Does toor dal increase uric acid? The reviewed evidence points the other way. Most uric acid is made inside the body, as the last step of purine chemistry, and a 2019 Nutrients review reports that plant foods carrying relatively more purines, it names peas, beans, lentils, spinach, mushrooms and cauliflower, show no association with uric acid. A study published in the New England Journal of Medicine in 2004 followed 47,150 men for 12 years and found that purine-rich vegetables were not associated with an increased risk of gout, while meat and seafood were linked to a higher risk, and dairy to a lower one. The 2019 review adds one caution: someone who already has advanced kidney disease or gout should eat high-purine plant foods with caution. These sources give no safe daily amount of toor, so none is set here.

Who should limit toor dal

Most people need no limit, and the guidelines give none for healthy adults beyond the 85 g plate share. Two groups carry cautions: the 2019 Nutrients review says high-purine plant foods deserve caution for anyone who already has advanced kidney disease or gout, and toor carries both protein and potassium in real amounts. If either condition is yours, take the dal question to your doctor or dietitian and ask about protein, potassium and purines in your own portions. A gassy start is not a reason to stop; the review notes that the discomfort subsides after a period of adaptation to the higher intake.

The guideline portion is a plate share, not a pill. The ICMR-NIN vegetarian My Plate for the Day gives pulses and legumes 85 g a day for an adult, and that is the figure to work with. Two katoris of cooked dal, one at each meal, come from 60 g of dry dal, sit comfortably inside that 85 g, and bring about 199 kcal and 13 g of protein from the dal alone, with the tadka on top. The guidelines set no toor-specific daily cap, so none is set here; the 85 g is the guideline's figure for all pulses, and varying the dals across the week keeps the plate varied.

Toor's place in the kitchen is the everyday pot. The plain toor dal recipe cooks the dal with a ghee-cumin tadka in about an hour including the soak, and sambar turns the same dal into the South Indian staple. Dal palak folds in spinach, one of the leafy greens the guidelines list as plant iron foods, and toor dal khichdi is the rice-pulse pair the protein section describes. The dal needs little ceremony: a 20 to 30 minute soak for the everyday cook, or an overnight soak in the fridge when you plan ahead. All eight toor recipes, with their times and portions, are on the toor dal recipes page, and the dal itself, from names to storage, starts at the toor dal hub.

Is toor dal good for health?

Yes, on the numbers above. Each 100 g of raw toor dal carries 21.7 g of protein, 9.1 g of fibre and 1.56 g of fat, plus a glycemic index of 20 and about 99 kcal in a cooked katori. The ten benefits above spell those numbers out, and the honest caveats on gas and uric acid sit below. What good for health means for you depends on your diet and your condition, so portions stay personal.

Does toor dal increase uric acid?

The reviewed evidence does not link it to higher uric acid. Most uric acid is made inside the body, and a 2019 Nutrients review found no association between uric acid and plant foods with relatively more purines, listing peas, beans, lentils, spinach, mushrooms and cauliflower. A study that tracked 47,150 men over 12 years tied gout risk to meat and seafood, not to purine-rich vegetables. Anyone with advanced kidney disease or gout should eat high-purine plant foods with caution.

Can toor dal cause gas?

It can, as with most pulses. The 2019 review in Current Opinion in Food Science explains why: galacto-oligosaccharides in the dal escape digestion in the small intestine and ferment in the colon, releasing gas. The same review notes the explanation has recently been questioned, and that most people adapt within a few weeks of eating pulses regularly if they keep the intake up. Portions stay personal.

Why toor dal is not good for health?

For most people there is no documented reason. The two documented cautions are the short-term gas that settles within a few weeks of regular eating, and the Nutrients review's note that people with advanced kidney disease or gout should eat high-purine plant foods with caution. Beyond that, toor dal carries 21.7 g of protein and 9.1 g of fibre per 100 g.

Does toor dal have protein?

Yes, 21.7 g in every 100 g of raw dal, and a cooked katori carries about 6.5 g. The number matters most in a pair: with rice or roti at a 3:1 raw-weight cereal-pulse mix, the two foods can meet the need for each of the essential amino acids. The full table is on the arhar dal protein per 100g page.

Is toor dal good for kidney patients?

That answer belongs to a doctor or dietitian, not a page. The one documented caution comes from the 2019 Nutrients review: high-purine plant foods call for care when advanced kidney disease or gout is already present. IFCT 2017 gives no purine figure for toor dal, and toor carries protein and potassium in real amounts. Bring the dal question to your next consultation.
