Sushi's hidden gluten

• Sticky sushi rice is typically made with Japanese rice vinegar or rice wine that, you guessed it, contain gluten.
  
• And that “crab meat?” It’s not crab, of course, but pulverized white fish mixed with a binder—there’s the wheat—to mimic the texture of crab.
  
• Even the sesame seeds that sometimes coat sushi rolls may be mixed with a wheat product.
  
• And let’s not even get started on possible cross-contamination issues from tempura, soy sauce, and more.
