Soy Allergy at Thai Restaurants
Understanding Soy Allergy
Soy is pervasive in processed foods and restaurant cooking, especially in Asian cuisine. Soy allergy means avoiding soy sauce, tofu, edamame, miso, tempeh, and countless emulsifiers used in sauces, marinades, and processed proteins.
Thai Cuisine — Allergen Profile
Thai cuisine is built on a foundation of peanuts, fish sauce, shrimp paste, soy sauce, and eggs — making it one of the highest-risk cuisines for multiple allergies. The challenge is that foundational allergens appear as invisible base seasonings rather than listed ingredients. What reads as a 'vegetable curry' often contains shellfish-derived shrimp paste.
Primary allergen risks in Thai cuisine: peanuts, shellfish (shrimp paste), soy, eggs.
Soy Allergy + Thai: What You Need to Know
Thai cuisine is very high risk for soy allergy. Soy sauce appears in most savory Thai dishes as a base seasoning. Tofu is widely used as a protein option. The challenge is that soy sauce is used as a kitchen staple rather than a listed ingredient, meaning dishes that don't mention soy may contain it in the seasoning base. Requesting fish-sauce-only preparations can help reduce soy exposure.
