The short answer
100 g of soybean (dry, uncooked) has 37.8 g of protein and 377 kcal.1 That's about 76% of the 50 g of protein ICMR-NIN suggests a day for a 60 kg adult.2
Nutrition in 100 g of soybean
| Per 100 g | Amount |
|---|---|
| Energy | 377 kcal (1579 kJ) |
| Protein | 37.8 g |
| Fat | 19.4 g |
| Carbohydrate | 10.2 g |
| Fibre | 22.6 g |
| Water | 5.5 g |
These figures are for dry, uncooked soybean. Dal soaks up water as it cooks, so 100 g of cooked dal holds much less protein than 100 g of dry dal, even though the protein in the pot hardly changes. Weigh it dry for an accurate count.
How much soybean for your protein?
The amounts below are worked out from IFCT's figure of 37.8 g per 100 g. To see how soybean fits into a whole day, add it in the day builder.
| To get | Eat about | Calories |
|---|---|---|
| 10 g of protein | 26 g (dry, uncooked weight) | 98 kcal |
| 20 g of protein | 53 g (dry, uncooked weight) | 200 kcal |
| 30 g of protein | 79 g (dry, uncooked weight) | 298 kcal |
How soybean compares
Soybean has more protein per 100 g than 100% of the 542 foods in IFCT 2017. Here it is beside the other pulses and dals we cover:

| Moong dal | 23.9 g | 326 | 30% |
| Urad dal | 23.1 g | 324 | 29% |
| Whole moong | 22.5 g | 294 | 31% |

Protein quality
Pulses are among the richest plant sources of protein. Their protein is rich in lysine but low in the sulphur amino acids (methionine and cysteine), while cereals are the other way round. That is why dal with rice or roti works so well: eaten together, they give a more complete mix of the amino acids your body needs.3

Common questions
How much protein is in 100 g of soybean?
37.8 g, according to the Indian Food Composition Tables 2017 from ICMR-NIN. That's for dry, uncooked soybean, per 100 g of the edible part. 100 g also gives 377 kcal.
How much soybean gives 20 g of protein?
About 53 g (dry, uncooked weight). That's roughly 40% of the 50 g a day ICMR-NIN suggests for a 60 kg adult.
Is soybean a good source of protein?
41% of its calories come from protein, and it has more protein per 100 g than 100% of the 542 foods in IFCT 2017. Pulses are among the richest plant sources of protein.
Does cooking soybean reduce its protein?
Barely. What changes is the weight: soybean soaks up water, so 100 g cooked has far less protein than 100 g dry. The protein you put in the pot stays in the dal. Weigh it dry, or count the dry amount you cooked.
