Why fructans food checker matters
Fructans are chains of fructose molecules found in wheat, onions, garlic, and many other foods. They're a type of FODMAP that can cause digestive symptoms in sensitive individuals because they're not well absorbed in the small intestine.
- Garlic-infused oil is low-FODMAP since fructans don't dissolve in oil
- Green parts of leeks and scallions are lower in fructans
- Sourdough bread may be better tolerated than regular wheat bread

Serving size, prep, and portion notes for rockfish
Rockfish is one of the cleanest entries in our fish data. Histamine A, no histamine liberation, no tyramine, no salicylate, no oxalate, no nickel, no gluten, no lactose, no dairy protein, no added sulfites or nitrites, nothing in the nightshade or glutamate columns. Its only mark is a mild fermentability rating, which is not the kind of flag that keeps people out of a food. The complication with rockfish is not chemistry, it is identity. On the US Pacific coast, rockfish is a market name spanning dozens of species in the genus Sebastes, and thirteen of them can legally be sold as Pacific red snapper in California, Oregon and Washington. On the Atlantic side, rockfish usually means striped bass, a completely unrelated fish. Some Sebastes species are extraordinarily long-lived, with rougheye rockfish documented at 205 years, and that longevity drives both the mercury guidance and the sustainability story. FDA and EPA place rockfish in the Good Choices tier at about one serving a week rather than the two to three servings allowed for shorter-lived fish. If you are logging rockfish, the useful discipline is writing down which fish you actually ate.
Watch for
Clean on every FODMAP group, with a mild fermentability rating as its only chemistry flag. During a strict elimination phase, log a portion rather than treating rockfish as an unlimited free food / Rockfish is a market name, not a species. Pacific rockfish means one of dozens of Sebastes species, while rockfish on the US East Coast and around the Chesapeake normally means striped bass. Note which one you ate, because they are unrelated fish with different advisories / Pacific red snapper, Pacific snapper and rock cod on a menu or a label are usually rockfish. That means a rockfish reaction can hide inside a snapper journal entry, and vice versa / Longevity drives the mercury picture. Deep-water Sebastes species can live past a century, with rougheye rockfish recorded at 205 years, and FDA and EPA advice puts rockfish at roughly one serving a week rather than in the lowest-mercury tier / Rockfish is the default fish for tacos, blackening and beer-battered fry-ups. Blackening rubs are built on paprika and cayenne, which bring nightshade and salicylate, and batter brings wheat. That is where a rockfish meal actually picks up its trigger load
