Low FODMAP Thai Food: How to Navigate Thai Restaurant Menus With IBS

Low FODMAP Thai Food: How to Navigate Thai Restaurant Menus With IBS

By Dr. Onikepe Adegbola, MD PhD — Johns Hopkins-trained physician-scientist

Thai cuisine is flavor-forward but FODMAP-complex. Garlic and shallots (onion family) are pounded into nearly every curry paste. Fish sauce is safe but it's combined with HFCS-laden sweet chili sauces. The good news: Thai cooking also features rice noodles, fresh herbs, and grilled meats — all safe foundations.

Key Takeaways

  • Rice noodles > wheat noodles — always specify rice noodles (sen lek, sen yai)
  • Jasmine rice is served everywhere and is FODMAP-free
  • ALL curry pastes (red, green, yellow, Massaman, Panang) contain garlic + shallots
  • Fresh herbs (basil, cilantro, lemongrass, galangal) are all FODMAP-safe
  • FODMAP digestive enzymes essential for hidden garlic in Thai sauces

Safe Thai Orders

  • Grilled chicken (gai yang) — marinated with lemongrass, turmeric, coriander. Usually safe.
  • Jasmine rice (khao suay)
  • Rice noodle stir-fry (ask for plain) — rice noodles + egg + bean sprouts + scallion tops
  • Morning glory stir-fry (pak boong) — water spinach in garlic-infused oil (garlic-infused OK, whole garlic not)
  • Tom yum soup (clear broth) — lemongrass, galangal, kaffir lime, chili. Contains shrimp paste but low FODMAP in normal amounts. Ask: no mushrooms, no onion.
  • ⚠️ Pad Thai — rice noodles are OK, but sauce contains shallots, tamarind, possibly sugar. Ask for light sauce.
  • Green/red/yellow curry — curry paste = garlic + shallots + shrimp paste + chili. High FODMAP.
  • Massaman curry — potato + onion + peanut + curry paste
  • Som tum (papaya salad) — green papaya is OK but dressing has garlic + sugar
  • Larb (meat salad) — shallots are a primary ingredient

Your Best Order

"Grilled chicken, jasmine rice, stir-fried morning glory. No curry paste, no mushrooms."

Take FODMAP digestive enzymes before eating. See our sushi guide and Indian food guide.
