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
- Spelt and ancient grains still contain fructans despite marketing claims
- Portion size matters - small amounts may be tolerable

What to know about celeriac
Celeriac, the knobbly root sold as celery root, is one of the quietest vegetables on the food chemistry panel: A for histamine, histamine liberation, salicylate, oxalate, nickel, glutamate, sulfite, tyramine, gluten and nightshade, with only a B for total FODMAPs and a B for polyols. That clean sheet is why it shows up so often as a substitute for harsher roots. It also carries one caution that outweighs every grade on this page: celery is one of the fourteen allergens that must be declared on food labels across the EU and UK, and celeriac specifically is a well documented cause of severe reactions, up to and including anaphylaxis. Our columns score food chemistry, not IgE allergy, so a true celery allergy is invisible in the grades above. If celery stalk, celery seed or celery salt causes you trouble, celeriac is not the gentler version of it.
Watch for
- Celery is a declarable allergen in the EU and UK and celeriac is one of its most reactive forms.Reported reactions run from oral itching and swelling through to anaphylaxis, so this is an allergy question rather than a sensitivity one.
- Cooking is not a reliable safeguard.Celery carries both heat labile and heat stable allergens, so cooked celeriac in a soup or a gratin has still caused reactions in people who are allergic.
- Birch and mugwort pollen allergy is the usual route in.In the birch, mugwort and celery pattern, cross reactive proteins mean pollen sensitised people react to celeriac, and mugwort sensitisation is associated with the more severe systemic reactions.
- Celery is one of the classic triggers for food dependent exercise induced anaphylaxis, where the food is tolerated at rest but provokes a reaction when eaten shortly before exercise.
- Gentler than its own stalk on the gut.Celeriac grades B for FODMAPs and B for polyols, while celery stalk grades D and E, so if celery bloats you rather than sets off your immune system, the root is the easier part of the plant in reasonable portions.
