Whiting

Whiting is notable for histamine. Clear on FODMAPs, lactose, gluten, fructose, oligosaccharides, sorbitol, sucrose, tyramine, salicylate, nickel and oxalates.

Whiting contains only low levels of histamine. Whiting is a lean white fish, low in the free histidine that bacteria turn into histamine - unlike tuna, mackerel and sardine, where the scombroid problem lives. It has soft flesh and is among the quickest white fish to go off, so the counter's clock matters here more than anywhere else on this list. Freshness is the whole of it: the count climbs with every hour out of the cold, and no label records it. Amounts vary by brand and recipe, so always check the label of the exact product.
