10 benefits of green gram (moong) sprouts and whole green moong

A sprouting bean is a seed switching itself on. Once soaked it swells, the skin loosens, the tail (the root, not the shoot) pushes out within a day or two, and the seedling begins to live off the food stored in the bean. Four of the sources describe what that does to the food value. The 2023 study in Frontiers in Nutrition that optimised germination conditions for mung beans measured more polyphenol extract in germinated beans than in ungerminated ones, about three times as much under its best conditions, and found hypoglycaemic activity for that extract in test-tube and mouse experiments; nothing in it was tested in people. The 2019 review in Nutrients identifies vitexin and isovitexin as the major polyphenols of the mung bean. In the ICMR-NIN dietary guidelines, sprouting is one of the everyday home methods that help the body digest legumes and use more of their nutrients, and it also increases the amount of certain vitamins. And the history chapter of IFCT 2017 records that the early Indian food tables found vitamin C in sprouted pulses and none in unsprouted ones, with more in sprouted green gram than in sprouted bengal gram.

What this page cannot give is a nutrition table for sprouts. IFCT 2017 prints no values for sprouted moong, so every nutrient figure here is for the dry grain, and a bowl of sprouts is counted by the dry beans that went into it. The changes that come with germination are described in words, because their size depends on how the beans are sprouted: the 2023 study's best conditions were an 11-hour soak and three days of germination, which is longer than a kitchen sprout is usually grown.

1. More polyphenols than the dry bean

The 2023 Frontiers in Nutrition study concluded that germination is an effective way to increase the polyphenol content of mung beans. Among the compounds it identified in the sprouted beans were vitexin and isovitexin, the two that the 2019 Nutrients review calls the bean's major polyphenols. Read this as a plus rather than a promise: the study measured what is in the bean, not what it does in people.

2. Activity linked to blood sugar, in laboratory tests

The same study tested the polyphenol extract of its germinated beans: it inhibited the enzyme alpha-glucosidase in the test tube and lowered blood sugar in diabetic mice. Those are laboratory results, not clinical ones, and they sit beside a GI of 38 for the cooked bean, which is already low. For a person with diabetes the practical reading is that moong is a food, not a medicine, and the US FDA advice on raw sprouts, under side effects below, covers diabetes too.

3. Minerals that are easier to absorb

According to the ICMR-NIN dietary guidelines, the nutrients in sprouts are more bioavailable than those in the whole grain, and using sprouted grains in a meal improves the bioavailability of iron. The dry bean starts with 4.9 mg iron and 2.7 mg zinc per 100 g, so there is something worth absorbing.

4. Easier on the stomach once soaked, sprouted and steamed

Soaking and sprouting are two of the household methods that the ICMR-NIN dietary guidelines credit with improving the digestibility of legumes. Steaming the sprouts for five minutes softens them further.

5. Volume and crunch from the same beans

Soaking and sprouting add water and bulk to the bean, and nothing else goes in. The 50 g of dry moong behind a bowl of sprouts carries 147 kcal, 11.3 g protein and 8.5 g fibre by the IFCT dry-grain values, and once sprouted it fills far more of the bowl than it did dry. That is the case for sprouts in a weight-loss diet: more chewing and more volume from the same beans.

6. Protein that completes rice and roti

Whole green moong has 22.5 g protein per 100 g of dry beans. The 2018 review in Food and Nutrition Research reports that mung bean, measured against the FAO/WHO amino acid recommendations, is a good protein source that falls short only in methionine and cysteine. Cereals supply those two and are low in lysine, the ICMR-NIN dietary guidelines explain, so pulses and grains eaten together in the right proportion cover all the essential amino acids between them, which neither does alone.

7. Fibre for fullness and regular digestion

At 17 g per 100 g, the whole bean has nearly twice the fibre of the split dal; the difference is in the green skin. By the account in the ICMR-NIN dietary guidelines, dietary fibre slows down the absorption of carbohydrates and fats, makes a meal more satisfying, adds bulk to the stool and keeps the bowel working properly.

8. A low glycemic index

The GI of plain cooked green gram is 38 in the University of Sydney's listing, and the low band runs up to 55. Mudryj and colleagues, in their 2014 review of pulses, report that because pulses are high in fibre and have a low GI, they are of particular benefit to people with diabetes, helping to maintain healthy levels of blood glucose and of insulin, and that eating pulses improves serum lipid profiles. How to read the GI figure is explained under green gram protein per 100 g.

9. Iron and folate

Per 100 g the dry bean gives 4.9 mg iron and 145 mcg folate. Fruits rich in vitamin C, lemon among them, improve the absorption of iron from plant foods when they are part of the meal (ICMR-NIN dietary guidelines), so lemon on the sprouts is not decoration. Folate matters most before and during pregnancy; the 50 g of dry whole moong in one serving supplies about 73 mcg.

10. Magnesium, potassium and very little sodium

With 198 mg magnesium, 1177 mg potassium and 12.5 mg sodium per 100 g, whole moong is a high-potassium, low-sodium food. The same potassium is the one thing to watch for anyone on a kidney diet, covered below.

Sprouts are grown warm and damp for one to three days, and food kept warm and damp spoils quickly. Rinse the beans well before soaking, rinse the sprouts twice a day while they grow, move them to the fridge once the tails show, and eat them soon. A sour smell or a slimy feel means the batch is past it; throw it away.

The US FDA adds that the warm, humid conditions sprouts grow in also suit bacteria such as Salmonella, Listeria and E. coli, and it advises older adults, pregnant women, children and people with weakened immune systems (its examples include diabetes) to avoid raw or lightly cooked sprouts, mung bean sprouts among them. For other adults, the ICMR-NIN dietary guidelines say sprouts can be eaten as they are or with a garnish.

Beyond hygiene, three groups should keep portions small. People who are not used to fibre may get gas or bloating from a bean with 17 g fibre per 100 g; start with half a bowl and increase slowly, since most people who get gas from pulses adapt within a few weeks of eating them regularly, a 2019 review reports. Anyone on a potassium-restricted diet for kidney disease should ask their doctor before eating moong regularly, because the dry bean holds 1177 mg potassium per 100 g. And people with gout or high uric acid, who are often told to limit pulses, should ask their doctor how much fits. With diabetes or any other medical condition, get your doctor's or dietitian's view before sprouts become a daily habit.

The sources used here give no daily figure for sprouts on their own. The ICMR-NIN dietary guidelines include pulses and legumes in the daily plate, and the 2014 review of pulses notes that half a cup of beans or peas a day can improve the quality of a diet by raising the intake of protein, fibre, iron, zinc, folate and magnesium. One bowl of sprouts a day, grown from about 50 g of dry moong, fits that pattern: by the IFCT dry-grain values those 50 g carry 147 kcal, 11.3 g protein and 8.5 g fibre. Count the bowl as your pulse serving rather than a free extra, and keep the dal at dinner smaller on sprout days. More is not better; the fibre load climbs and the rest of the meal shrinks. Children need a smaller bowl, and the FDA caution on raw sprouts above applies to them. If sprouts are new to you, start with half a bowl and build up slowly, and drink enough water with them.

Steam first, then season. Five minutes in a steamer or a colander over boiling water softens them and keeps the crunch. Then: sprouts chaat with onion, tomato, cucumber, lemon, chaat masala, pomegranate and roasted peanuts, a common way and a full snack at about 199 kcal a serving, counted on the dry moong and peanuts that go in; a sundal tempered with mustard seeds, curry leaves, green chilli and grated coconut; a handful stirred into poha, upma or a vegetable pulao in the last minute; a sprouts salad with cucumber, carrot and a curd dressing; or sprouts cooked down with onion, tomato and garam masala as the Maharashtrian usal, eaten with pav. Sprouts also go into a moong chilla batter or a soup, and a bowl of steamed sprouts with lemon, salt and pepper is breakfast in many homes. The growing itself, timings by season and the mistakes that give you mush are in how to sprout moong, and the bean's cooking, storage and buying notes are in the green gram guide.

Is sabut moong easy to digest?

Boiled or steamed, yes: well-cooked whole moong turns soft, and Indian cooks regard it as one of the lighter pulses. The ICMR-NIN dietary guidelines list soaking, sprouting and pressure cooking among the ways to improve the digestibility of pulses. Raw sprouts are a step harder, and the whole bean's 17 g fibre per 100 g can cause gas if you are not used to it, so soak, sprout or cook it well and build the portion up slowly.

Can green gram cause gas?

It can, especially for people new to pulses; at 17 g per 100 g, whole moong is a high-fibre food, and pulses also carry sugars that are fermented in the colon. Soak for 8 to 12 hours and discard the water, then sprout the beans or cook them soft: the ICMR-NIN guidelines count soaking and sprouting among the methods that make pulses easier to digest. Start with half a bowl; most people adapt within a few weeks.

Is sabut moong good for uric acid?

People with gout or high uric acid are often told to limit pulses for their purines, but the evidence is milder than the advice: over 12 years, 47,150 men who ate more peas, beans, lentils and other purine-rich plant foods got no more gout, unlike those who ate more meat or seafood. No source used here gives a purine figure for moong. If you already have gout or a high reading, set the portion with your doctor or dietitian.

Can green gram sprouts be eaten raw?

Most adults can eat them raw: the ICMR-NIN dietary guidelines say sprouts need no further processing, and keeping them in the fridge, rinsing them before eating and finishing them soon keeps them fresh. The US FDA, though, tells children, the elderly, pregnant women and anyone with low immunity, diabetes included, to stay away from raw or lightly cooked sprouts.

How many moong sprouts can I eat in a day?

About one bowl a day, grown from roughly 50 g of dry beans, suits most adults. By the IFCT dry-grain values those 50 g carry 147 kcal, 11.3 g protein and 8.5 g fibre; no values are printed for the sprouts themselves. Count the bowl as your pulse serving for the day rather than an extra, and give anyone new to sprouts a smaller bowl.

What are green gram benefits for skin?

Moong flour is a traditional ubtan (a scrub paste with turmeric and milk or curd), and that is where the skin reputation comes from; none of the sources used here tests eating moong for skin. Eaten, the dry bean gives 22.5 g protein and 2.7 mg zinc per 100 g as part of an ordinary balanced diet. For a skin problem, talk to your doctor or dietitian.
