Quick Summary
itsu offers Japanese-inspired food that can work for FODMAP dieters if you focus on sashimi and plain rice. The main challenges are soy sauce (contains wheat) and hidden garlic/onion in most hot dishes.
Best bets: Sashimi + plain rice + small edamame (bring your own GF tamari)
Always avoid: Soy sauce, gyoza, teriyaki, miso soup, katsu, tempura
The Soy Sauce Problem
Traditional soy sauce is made with wheat and is NOT gluten-free or FODMAP-safe. At itsu:
- All provided soy sauce contains wheat
- Most hot dishes use soy sauce in cooking
- Many dressings contain soy
Solution: Bring your own gluten-free tamari (available at supermarkets). It provides the soy sauce flavor without wheat.
