The short answer
100 g of tuna (raw) has 24.5 g of protein and 112 kcal.1 That's about 49% of the 50 g of protein ICMR-NIN suggests a day for a 60 kg adult.2
Nutrition in 100 g of tuna
| Per 100 g | Amount |
|---|---|
| Energy | 112 kcal (470 kJ) |
| Protein | 24.5 g ± 0.3 |
| Fat | 1.4 g |
| Carbohydrate | 0 g |
| Fibre | 0 g |
| Water | 72.1 g |
These figures are for raw tuna, edible part, without bones or shell. Cooking drives out water, so cooked fish has more protein per 100 g than raw. Weigh it raw for an accurate count.

Protein quality
Fish and seafood have complete protein: all the essential amino acids in good proportions.3 Most fish are lean, so they give a lot of protein for few calories.

Common questions
How much protein is in 100 g of tuna?
24.5 g, according to the Indian Food Composition Tables 2017 from ICMR-NIN. That's for raw tuna, per 100 g of the edible part. 100 g also gives 112 kcal.
How much tuna gives 20 g of protein?
About 82 g (raw weight). That's roughly 40% of the 50 g a day ICMR-NIN suggests for a 60 kg adult.
Is tuna a good source of protein?
89% of its calories come from protein, and it has more protein per 100 g than 99% of the 542 foods in IFCT 2017. Fish and seafood have complete protein: all the essential amino acids in good proportions.
Is this for raw or cooked tuna?
Raw, edible part, without bones. Cooking drives out water, so 100 g cooked has more protein than 100 g raw. If you weigh it cooked, your count will come out low.
