Serving size, prep, and portion notes for whitefish
Whitefish is two different foods wearing one label. It can mean the actual freshwater whitefish, a lake species in the salmon family that reaches most people smoked, and it is also used loosely for any lean white-fleshed fish such as cod, haddock, pollock or sole. Either way, fresh whitefish is one of the cleanest proteins you can log: graded clean for FODMAPs, gluten, lactose, salicylates, oxalates, nickel and sulfites, with only a moderate histamine grade against it. That histamine grade is the whole story, and it is really a question of handling. Fish accumulates histamine after it is caught, so a fillet cooked the day you buy it is a very different food from smoked whitefish that has been cured, hot smoked and left in a deli case, or from a tub of whitefish salad made several days ago.
Watch for
Graded moderate for histamine, and that grade moves with freshness. Cooking, freezing and smoking do not remove histamine that has already formed in the fish / Smoked whitefish, whitefish salad and whitefish spread are cured and stored products, so they belong in the high histamine column rather than alongside a fresh fillet / Whitefish roe, sold as golden caviar, is salted and preserved and carries the same amine and sodium caveats as other roe / Because whitefish is a loose label, the species in the packet varies. If you are chasing a fish reaction, log the actual species rather than the word on the front / Plain fish is gluten free and low FODMAP, but battered, breaded or crumbed whitefish brings wheat, and the seasoning mix usually brings garlic and onion powder
