🌍 Regional Safety Checker
Sushi is generally safe, but US restaurants widely use imitation crab (wheat) and standard soy sauce (wheat).
In the US, imitation crab (surimi) in California rolls almost always contains wheat starch. US sushi spots rarely offer gluten-free soy sauce (tamari) by default, so it is highly recommended to bring your own.
The Full Answer
Traditional sashimi (plain raw fish) and sushi rice (seasoned with rice vinegar, sugar, and salt) are naturally gluten-free.
However, eating sushi at a restaurant is a minefield for celiacs. The biggest danger is Soy Sauce, which is brewed with wheat. Imitation crab (surimi), used in all California rolls, uses wheat starch as a binder. Eel sauce (unagi) and ponzu sauce are made with soy sauce.
Tempura rolls and anything with "crunch" or "crispy" flakes use wheat flour. Additionally, cross-contamination on cutting boards is rampant. To eat sushi safely, bring your own tamari (GF soy sauce), order plain fish/veg rolls, avoid imitation crab, and ask the chef to use a clean cutting board and knife.

Ingredients to understand
Label terms that come up with sushi — see what each really means for celiacs.
Celiac Safety Glossary
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
- Cross-contamination
- Cross-contamination (or cross-contact) occurs when gluten-free food comes into contact with gluten-containing food or surfaces — such as shared cutting boards, toasters, fryers, or utensils — rendering otherwise safe food dangerous for people with celiac disease.
- Wheat starch
- Wheat starch is wheat flour that has had the gluten protein washed out. While some European gluten-free foods use codex-grade wheat starch (tested below 20 ppm), it can still trigger reactions in sensitive individuals.
