Bangkok Food Allergy
Travel Guide
Fish sauce is in everything. Shrimp paste is in the curry. Peanuts are on the pad thai. Bangkok is genuinely challenging for allergy travelers and genuinely worth it. This hub links every guide you need, in the order you will need it.
The single most important preparation step for Bangkok: build your Thai-language allergy card before you land.
Build My Bangkok Allergy CardThe Bangkok allergen problem in plain terms
Thai cooking uses three structural ingredients that most allergy travelers do not see coming: nam pla (fish sauce) as the foundational seasoning in virtually every savory dish, kapi (shrimp paste) as the base of curries and many dipping sauces, and peanuts as garnishes and fillers across a wide range of dishes from pad thai to larb. These are not optional additions. They are the cooking.
The implication for travelers: a verbal "no peanuts please" at a Bangkok restaurant often fails not because the server is careless, but because the kitchen is simultaneously managing high volume, the server may not communicate derivative ingredients to the kitchen, and the baseline assumption is that ingredient modification is not the norm. A written Thai-language card that specifies exactly what your allergy covers, including derivatives, changes that dynamic.
Bangkok's three core hidden allergens
- Fish sauce (nam pla): fermented fish, used like salt across all savory Thai cooking
- Shrimp paste (kapi): fermented shrimp, base of green and red curry pastes, many dipping sauces
- Peanuts (thua lisong): garnish and base ingredient in pad thai, satay, larb, many salads

Your Bangkok allergy card
A written Thai-language allergy card is the single most effective tool you have in Bangkok. It removes the verbal translation layer between what you say in English and what the kitchen understands in Thai. It specifies derivative ingredients, not just the obvious allergen. And it signals severity in a way that a verbal request often does not.
AllergyPass builds free multilingual allergy cards in Thai and English, formatted specifically for restaurant use. Generate yours before you land, print a copy, and save a digital version on your phone home screen.
Where to stay
Neighborhood choice in Bangkok is a food safety decision. The area you stay in determines your proximity to international hospitals, the density of international restaurants nearby, and the quality of supermarket access for labeled food. Lower Sukhumvit is the most practical base for most allergy travelers.
