Is celery seed reflux diet-compatible?

Watch for

• Celery is one of the fourteen allergens that must be declared on EU and UK labels, and that includes celery seed, celery salt and celery extract.It is not on the United States major allergen list, so a US label can legally bury it inside "spices" or "natural flavor"
• Celery salt is simply ground celery seed mixed with salt, which is how celery hides in Old Bay, in the rim of a Bloody Mary, in tomato juice, hot dog and coleslaw seasonings, potato salad, brines and dry rubs.This is the single most common way people with celery allergy get an unexpected dose
• Gram for gram the seed carries far more celery protein than a stalk does, and cooking is not a reliable safeguard: the birch-related celery allergen breaks down with heat but others in celery do not, so cooked celery has still caused reactions
• Celery sits at the centre of the celery-mugwort-spice cluster, so mugwort and birch pollen allergy raises the odds of reacting to celery and to its Apiaceae relatives like carrot, fennel and coriander
• The food-chemistry grades themselves are quiet: histamine A, liberator A, salicylate A, oxalate A, nickel A and glutamate A, with the overall FODMAP figure unrated rather than high
