Hawaii’s food is one of the best reasons to visit. It’s also a minefield if you’re managing food allergies.

Soy sauce is the backbone of local cooking — it’s in poke, plate lunch gravies, teriyaki, and marinades you’d never guess contain soy. Macadamia nuts show up crusted on fish, tossed into salads, and folded into sauces. Coconut appears in haupia, kulolo, and curries. Shellfish lurks in saimin broth and shares display cases with poke.

The good news: Hawaii’s dining culture is casual and accommodating, rice is the default starch instead of bread, and every island has natural food stores and farmers markets where you can buy single-ingredient whole foods directly from growers. You can eat extremely well here with allergies. You just need to know where to look and what to ask.

Before you eat anything, know where the common allergens hide in Hawaiian food. Some of these are obvious. Others aren’t.

Soy is the single most pervasive allergen in local cuisine. “Shoyu” means soy sauce in local parlance — if you see it on a menu, that’s soy. It’s in shoyu chicken, teriyaki everything, most poke marinades, Spam musubi glaze, and virtually every plate lunch gravy. Standard soy sauce also contains wheat.

Shellfish risk comes from unexpected sources. Saimin — Hawaii’s local noodle soup — frequently uses a shrimp-based dashi broth. Poke display cases often sit next to shrimp and crab preparations, creating cross-contact risk. Luau buffets serve shellfish dishes adjacent to everything else.

Tree nuts and coconut are everywhere. Macadamia-crusted mahi mahi is a restaurant staple. Haupia (coconut milk pudding) shows up at every luau and most local dessert menus. Kulolo is taro-coconut pudding. The FDA classifies coconut as a tree nut for labeling purposes. Kukui nut (candlenut) appears in inamona, a traditional condiment served with poke.

Gluten hides in saimin noodles, malasadas (Portuguese donuts), manapua (steamed buns), loco moco gravy (thickened with flour), katsu breading (panko), and soy sauce itself. The flip side: rice is the default base for most local meals, which makes gluten-free eating easier than on the mainland.

Sesame — now the 9th major FDA allergen under the FASTER Act — is standard in poke (sesame oil and seeds), seaweed salads, and many plate lunch sides.

Be direct and specific. “I’m allergic to shellfish” or “no soy sauce — allergy” works. Hawaii’s restaurant culture is informal, and servers are used to dietary questions from visitors.

Know the local vocabulary. “Shoyu” means soy sauce. “Limu” means seaweed. “Pupu” means appetizer. If a server says “dat one get shoyu” — that dish has soy sauce in it.

For luaus, call the kitchen directly — not the booking agent — at least 48 hours ahead. Most commercial luaus (Old Lahaina Luau on Maui, Paradise Cove on Oahu, Smith’s on Kauai) handle allergy requests regularly, but they need advance notice. Note that Old Lahaina Luau switched from buffet to table service after reopening in 2024, which reduces cross-contamination risk compared to traditional buffet setups — but still call ahead. Other luaus remain buffet-style with high cross-contamination risk at serving stations. Request a plated meal if your allergy is severe.

Carry tamari packets. Real tamari is brewed without wheat, making it safe for most gluten-free diets (check labels — some brands add wheat). It’s the easiest swap you can make for soy sauce at any restaurant.
