With fish allergy, the immune system targets fish proteins – usually the stable muscle protein parvalbumin, found in many fish species. Allergic reactions can be triggered by direct contact, but also by fish vapors during cooking. Here you can see which foods are safe with fish allergy and where caution is needed.
With Fish Allergy, 677 foods are currently allowed and 35 foods are not recommended. Check all foods in the interactive tool above.
All foods without fish components are allowed. Meat, poultry, eggs, dairy, legumes, and tofu are good protein sources as fish substitutes. Rice, potatoes, vegetables, and fruit are also unproblematic.
Fish components can be found in Worcestershire sauce, Caesar dressing, Asian sauces (fish sauce, oyster sauce), gelatin, certain omega-3 supplements, some sausages, and surimi. Always read the ingredient list.
Fish and shellfish (shrimp, mussels, crab) belong to different biological groups. A fish allergy does not automatically mean a shellfish allergy. However, tolerance should be assessed allergologically.
Plant-based omega-3 sources include flaxseed, chia seeds, walnuts, hemp seeds, and canola oil (ALA). Algae oil capsules provide direct EPA and DHA without fish and are the best alternative for long-chain omega-3 fatty acids.
The main allergen parvalbumin occurs in most fish species. Some allergy sufferers tolerate individual species (e.g., tuna has less parvalbumin), but this must be tested under medical supervision. Self-testing is dangerous.
Yes, fish oil supplements may contain traces of allergenic fish proteins and can trigger allergic reactions. Use algae oil capsules instead as a safe alternative for omega-3 fatty acids.
