Is Sushi Gluten Free?

Yes, traditional sushi can be gluten-free as the primary ingredients—rice, fish, seaweed, and vegetables—naturally contain no gluten. However, caution is needed as some sushi preparations may include soy sauce (which typically contains wheat), imitation crab (surimi), tempura, or other ingredients containing gluten.

Frequently Asked Questions

Is sushi rice always gluten-free or do some places add ingredients with gluten?

Plain sushi rice is naturally gluten-free, but some restaurants may add vinegars or seasonings containing gluten. Always ask about ingredients if you have gluten sensitivity.

Do they use soy sauce with wheat in the rice or only for dipping?

Soy sauce with wheat is typically used for dipping. Plain steamed rice is usually cooked with just water and no soy sauce.

Are imitation crab sticks in California rolls safe for celiacs?

Imitation crab sticks typically contain wheat and are not safe for celiacs. Real crab meat would be a safe alternative in California rolls for those with celiac disease.

Can cross-contamination happen if they prepare tempura near my sushi?

Yes, cross-contamination can occur if tempura containing wheat flour is prepared near sushi due to airborne flour particles. The risk is higher for those with severe gluten sensitivity or celiac disease.

Is the wasabi paste at sushi restaurants typically pure wasabi or does it contain wheat fillers?

Most wasabi served at sushi restaurants is actually a mixture of horseradish, mustard, food coloring and other additives, not real wasabi. Real wasabi is extremely expensive and perishable, so it’s rarely used except at high-end Japanese restaurants.
