Ha!
I can beat you in this house we have allergies to:
Potato, peppers, tomatos, maize, soya, milk in any form, gluten/wheat, grapes/raisins, garlic, onion, rapeseed oil, vegetable oil, olive oil, peanuts, seaseme seeds, chillies, legumes, rice, one who doesn't eat beef, one who doesn't eat fish (and others but tbh I have got sick of writing stuff) All members of the house have allergies, there is a proper mix of who is allergic to what.
We have asthma, eczema, hayfever (everything from tree to grass pollen via fern spores), dust allergy, fur and feather allergies,
Needles to say this is why I single portion batch cooking, and we don't generally eat out it is manageable though, with the correct planning
