What to know about trout

Trout sits in a useful gap. It is a freshwater fish with real omega-3s, so it eats like salmon, but it grades far closer to white fish on the trigger chart: A for salicylates, oxalate, nickel, free glutamate, sulfites, gluten, lactose and nightshades, plus a clean A on both FODMAPs and fermentation load. The one place it costs you a notch is amines. Trout grades a borderline B for histamine, B for histamine liberation and B for tyramine, one step above the leanest white fish. That is not a warning so much as a freshness instruction: fresh trout is a low-trigger dinner, and trout that has been sitting is the version people react to.

Watch for

  • Borderline B on histamine, histamine liberation and tyramine, so it belongs in the fresh-and-fast category rather than the leftovers category.Cook it the day you buy it and do not keep cooked portions for days
  • Smoked and cured trout is a completely different proposition.Smoking and curing concentrate amines, which is why smoked fish is one of the first things dropped on a histamine protocol even when the fresh version is fine
  • Trout roe and trout caviar are salted, aged and preserved, so treat them as their own high-amine food rather than as trout
  • Almondine and meuniere preparations bring butter, flour and lemon, which is usually where a reaction to a trout dinner actually comes from
  • Nothing on the plant-chemical side to manage: salicylate, oxalate and nickel all grade A, which makes trout unusually easy to place in a multi-restriction diet
