Sensitivity notes
Why lectin food checker matters
Lectins are proteins found in many plant foods, especially legumes and grains. Some people follow low-lectin diets believing they reduce inflammation and digestive issues, though properly cooked foods have reduced lectin content.
- Proper cooking destroys most lectins - never eat raw beans
- Pressure cooking is highly effective at reducing lectins
- Peeling and deseeding reduces lectin content
- Fermentation can reduce lectins in some foods
- Sprouting may increase or decrease lectins depending on the food

What to know about 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
