If you have fish intolerance, you must exclude all types of saltwater and freshwater fish, including salmon, cod, tuna, trout, herring, and other varieties in any form — fresh, salted, smoked, or canned. You should also avoid fish sauces, broths, caviar, and canned cod liver, as they contain fish proteins and may trigger a reaction. When selecting recipes on the site, pay attention to alternatives: seafood is often replaced with meat, poultry, or plant-based proteins, and fish sauces are substituted with soy sauce or vegetable broths.
