Key takeaways
- Mung beans (Vigna radiata), also called green gram or moong, were first grown in India about 4,500 years ago and are now eaten across Asia and beyond.
- One cup of cooked mung beans gives about 14 g of protein, 15 g of fibre and 80% of the daily value for folate.
- Mung comes in many forms: whole, split, hulled, sprouted, flour and starch. Each cooks differently.
- Soaking, sprouting and slow cooking are traditional ways to make mung easier to digest.
If you grew up in South Asia, you probably know mung as moong: a yellow dal on a weeknight, a pot of khichari when someone felt unwell. If you grew up in China, it may be the sweet mung bean soup your family made on hot summer days. In Korea, it's crispy bindae-tteok pancakes. In the Philippines, it's a comforting bowl of ginisáng monggó.
It's the same small green bean. Few foods have travelled so far and been loved in so many kitchens.
Today in the west mung beans are entering their golden era. As focus on gut health, fibre, protein and nutrition grows, mung beans are now in the lime light.

This guide covers what mung beans are, what's inside them, how to cook them, and why we chose mung as the heart of Moong Pani.
What are mung beans?
Mung beans are the small, oval, olive-green seeds of Vigna radiata, a legume in the pea family. Like all legumes, the plant works with soil bacteria to pull nitrogen from the air, which helps enrich the soil it grows in.
They go by many names:
- Moong or mung (Hindi and across South Asia)
- Green gram (common in India and the UK)
- Lǜdòu (China), nokdu (Korea), đậu xanh (Vietnam), kacang hijau (Indonesia), monggó or mongo (Philippines)
If you've eaten fresh bean sprouts in a stir-fry or pho, or glass noodles in a spring roll, you've eaten mung. Most bean sprouts sold in North America are mung sprouts, and glass (cellophane) noodles are traditionally made from mung bean starch.
A 4,500-year-old food
Mung beans date back to India 4,500 years ago. From there, mung travelled to Southeast Asia (it reached what is now Thailand about 2,200 years ago), then on to China, Korea and Central Asia (overview).
Along the way, each culture made mung its own. In South Asia, it became savoury dals, khichari and sprouted salads. In China, it became mostly sweet: soups, pastes and mooncake fillings. In Korea, it became pancakes and a soft jelly called nokdumuk. Today it's also the base of some plant-based egg products.
In our home, a pot of golden mung broth is a staple. My grandmother, Ma, never called it a superfood. She simply made a big pot of mung broth all the time. Sundays brings memories of big family brunches and everything revolved around the vat of mung broth served with rice cakes, doklas, ganthias, crispy noodles, pickles and all kinds of munchies. If a little under the weather, mung broth we called moong pani was the first thing that was given to us — Anu
What's inside a mung bean?
Here's what one cup (202 g) of whole mung beans, boiled, provides according to USDA data (source):
| Nutrient | Amount | % Daily Value |
|---|---|---|
| Calories | 212 | – |
| Protein | 14.2 g | 28% |
| Fibre | 15.4 g | 55% |
| Carbohydrate | 38.7 g | – |
| Fat | 0.8 g | – |
| Folate | 321 µg | 80% |
| Thiamin (vitamin B1) | 0.33 mg | 28% |
| Manganese | 0.6 mg | 26% |
| Magnesium | 97 mg | 23% |
| Iron | 2.8 mg | 16% |
| Potassium | 537 mg | 11% |
A few things stand out:
- Protein and fibre together. Mung gives you almost as much fibre as protein. Most adults fall well short on fibre: in Canada, the target is 25 g a day for women and 38 g for men, and most people get about half that (CDHF).
- Folate. One cup covers most of a day's folate, a B vitamin the body uses to make new cells.
- Very little fat. Less than 1 g per cup.
- Plant compounds. Mung beans contain polyphenols, especially two called vitexin and isovitexin, which researchers are studying for their antioxidant activity (Hou et al., 2019).
Beans are also getting new respect in nutrition advice. Canada's Food Guide encourages choosing plant-based proteins more often, and the latest US Dietary Guidelines count beans, peas and lentils as protein foods (NPR).
The many forms of mung
| Form | What it is | Best for | Cooking time |
|---|---|---|---|
| Whole green mung | The whole bean, skin on | Soups, stews, broths, sprouting | 30–40 min (20–25 min if soaked) |
| Split mung (with skin) | Beans split in half, green skin still on | Dal, khichari | 25–30 min |
| Yellow moong dal | Split and hulled; the skin is removed | Quick dals, soups, pancakes, first foods | 15–20 min |
| Sprouts | Whole beans soaked until they sprout a tail | Stir-fries, soups, cooked salads | 1–3 min stir-fried, or simmered |
| Mung flour | Ground mung, usually yellow | Savoury pancakes (like cheela), batters | Minutes in a pan |
| Mung starch | Starch extracted from the bean | Glass noodles, jellies | Varies |
Whole mung keeps its skin, so it has the most fibre. Yellow dal is the gentlest and quickest to cook, which is why it's a traditional first food for babies in many parts of Asia.
How to prepare mung beans at home
Soaking
Whole mung beans don't need soaking, but soaking for 4–8 hours shortens cooking time and helps reduce some of the natural sugars in beans that can cause gas. Drain and rinse before cooking.
Cooking
Simmer 1 cup of rinsed whole mung in about 3 cups of water until soft, topping up if needed. Add salt near the end. Spices like ginger, cumin, turmeric and asafoetida (hing) are classic partners in South Asian cooking.
Sprouting
Soak whole mung for 8–12 hours. Drain, rinse, and leave in a covered colander or sprouting jar at room temperature. Rinse twice a day. Small tails appear in 1–2 days.
A food-safety note: raw sprouts can carry bacteria, because the warm, moist conditions they grow in also suit germs. Health Canada advises children, older adults, pregnant people and anyone with a weakened immune system to avoid raw sprouts, and recommends cooking sprouts thoroughly before eating them (Health Canada).
Why sprouting matters
When a mung bean sprouts, it starts to use its own stores of starch and protein to grow. In lab studies, sprouting mung beans for 3 days raised their total polyphenol content by about 1.5 times (Antioxidants, 2020). Soaking and sprouting also lower some of the natural sugars (called raffinose-family oligosaccharides) that give beans their reputation for causing gas.
This is why every bean that goes into Moong Pani is sprouted first. It's slower, but it's how mung has traditionally been made gentle and nourishing.
Mung in Ayurveda
In Ayurveda, India's traditional system of health and healing, mung is called the queen of pulses. It's considered sattvic (calming and clarifying), tridoshic (suitable for all three body types, or doshas) and light enough for cleanses, recovery and everyday meals. Mung and rice cooked together as khichari is the classic Ayurvedic reset meal, and a cup of thin mung broth is a traditional first food after illness or fasting.

Why we chose mung
We looked at every bean in the pantry: chickpeas, lentils, black beans, kidney beans. We kept coming back to mung, for four reasons:
- It's gentle. Across generations and cultures, mung has been the bean people turn to when they want something easy on the stomach.
- It's complete nourishment in a small package. Protein, fibre, folate and minerals, with almost no fat.
- It's versatile. Savoury or sweet, a sip or a meal. Mung works in broths, bowls and everything between.
- It's universal. From Delhi to Seoul to Manila, mung is already a comfort food. It belongs to everyone.

Frequently asked questions
Are mung beans and moong dal the same?
Yes. Moong dal is mung beans that have been split. Yellow moong dal has also had its green skin removed.
Do mung beans contain gluten?
No. Mung beans are naturally gluten-free. If you need to avoid gluten strictly, choose products made in a gluten-free facility, since beans can be handled alongside wheat.
Are mung beans a complete protein?
Like most beans, mung is lower in the amino acid methionine. Pairing it with a grain, as in khichari (mung and rice), gives a complete set of amino acids. This is one reason the pairing is so common.
Can babies eat mung beans?
Well-cooked, mashed yellow moong dal is a traditional first food in many Asian cultures. Talk to your child's healthcare provider about when and how to introduce new foods.
