Sensitivity notes
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 horseradish root
Fresh horseradish root is one of the cleanest fierce things you can eat. For all the violence of the flavour, the raw root grades A on histamine, tyramine, gluten, lactose, dairy protein, glutamates, sulfites, nitrites, nickel, fructans and nightshade, with only salicylate at C and a short list of Bs (FODMAPs, polyols, oxalate, histamine liberation, SIBO fermentation). Compare that with our horseradish sauce entry, which picks up lactose, dairy protein, histamine, tyramine and sulfite grades from the cream and the vinegar it is sold in, and the useful point falls out: when horseradish disagrees with someone, it is usually the jar rather than the root. The heat itself is not an ingredient at all. It is allyl isothiocyanate, a volatile compound the plant manufactures on the spot when its cells are ruptured, and it is the reason horseradish goes for your sinuses rather than your tongue and then vanishes within a minute.
Watch for
Salicylate C is the only grade of substance on the raw root. It is moderate and dose led, so a teaspoon grated over beef is a small exposure while a horseradish-heavy remoulade, Bloody Mary or dressing eaten regularly is not. On a strict salicylate elimination it belongs in the challenge phase rather than the free list / The heat runs on a clock. An intact root keeps sinigrin and the enzyme myrosinase in separate cells and tastes of almost nothing; grating breaks that wall and allyl isothiocyanate builds over the next couple of minutes, then starts evaporating. Vinegar halts the reaction, so a producer who adds it immediately is bottling a mild product and one who waits is bottling a savage one. Either way the volatile keeps leaving after opening / Cooking removes the point of it. Heat denatures myrosinase before it can act and drives off the isothiocyanate that has already formed, which is why horseradish baked into a crust or simmered into a sauce tastes dull and slightly cabbagey. It goes in at the end, off the heat / A route to real heat with no capsaicin and no nightshade. Horseradish grades A on nightshade, so if chilli, cayenne and paprika are off your list for that reason, the root is a genuine alternative rather than a compromise. The sensation is a different receptor entirely / FODMAPs B and polyols B, both moderate and both largely theoretical at condiment volumes. They only start to matter if horseradish is going in by the heaped spoonful
