How egg compares
Egg has more protein per 100 g than 55% of the 542 foods in IFCT 2017. Here it is beside the other eggs we cover:
| Eggs | Protein / 100 g | kcal | From protein |
|---|---|---|---|
| Omelette | 16.5 g | 170 | 40% |
| Egg yolk | 15.7 g | 297 | 22% |
| Duck egg | 14.6 g | 182 | 33% |

Other foods with similar protein: walnuts (14.9 g), rajgira (13.3 g), quinoa (13.1 g), sooji (11.4 g), bajra (11 g). For more protein per 100 g, try soybean (37.8 g), masoor dal (24.4 g), moong dal (23.9 g). See every food on one protein chart.
Protein quality
Egg protein contains all the essential amino acids in good proportions, which is why it is often used as the reference protein. The white is mostly water and protein; the yolk carries the fat and also has protein.3
Common questions
How much protein is in 100 g of egg?
13.3 g, according to the Indian Food Composition Tables 2017 from ICMR-NIN. That's for egg, per 100 g of the edible part. 100 g also gives 135 kcal.
How much egg gives 20 g of protein?
About 151 g. That's roughly 40% of the 50 g a day ICMR-NIN suggests for a 60 kg adult.
Is egg a good source of protein?
40% of its calories come from protein, and it has more protein per 100 g than 55% of the 542 foods in IFCT 2017. Egg protein contains all the essential amino acids in good proportions, which is why it is often used as the reference protein.
Is the protein in egg white or yolk?
Both. Per 100 g, raw egg white has 10.8 g of protein and raw yolk has 15.7 g (IFCT 2017). The white has almost no fat; the yolk carries the fat and most of the calories.
