Is Sushi High in Protein?

It depends on the roll. A salmon or tuna roll carries about 12 to 13g of protein for a full roll (8 pieces), while a California roll carries only about 5g, since its filling is imitation crab and avocado rather than a piece of fish.

The actual numbers

Per full roll (8 pieces, about 180g), from USDA’s dietary survey data:

Roll	Protein
Tuna roll	about 13g
Salmon roll	about 12g
California roll	about 5g

The gap comes down to what’s actually inside. Tuna and salmon rolls are built around a real fish filling, while California rolls typically use imitation crab plus avocado and cucumber. Imitation crab is made from surimi, a processed white fish paste, and USDA lists it at about 8g of protein per 100 grams, about a third of the 24g in real cooked queen crab.

Where it shows up in real cooking

Real fish, whether in a roll or on its own, is where the protein actually comes from. See the grilled salmon here, or browse everything tagged seafood for real fish-forward cooking.

FAQ

Why does a California roll have so much less protein than a salmon roll?

Because of the filling. A California roll is typically imitation crab, avocado, and cucumber. Imitation crab is a processed fish paste with about a third of real crab’s protein, and avocado and cucumber carry very little. A salmon or tuna roll is built around a piece of fish, which is most of the gap.

Does nigiri have more protein than a roll?

By weight, yes. USDA’s survey data puts tuna nigiri at about 10g of protein per 100 grams, against about 7g for a tuna roll, since nigiri is mostly fish over a small amount of rice while a roll spreads the fish through rice, nori, and other fillings. The exact number per piece still depends on the fish and the portion.
