What you reacted to is going to depend on what exactly was in the specific product you ate. But it’s unlikely to be nitrates (if it’s even possible to be allergic to them, all food allergies but one are caused by protiens). As all those foods you list as not reacting to also contain nitrates. As do most packaged meat products, and a lot of canned goods, since the purpose of the stuff is to prevent botulism bacteria from taking hold.

Whoa there. I’m allergic to nitrites. Full stop. Sounds like @ChuckV has a different allergy, but I’m talking about tested and proven. Not sure where you got the nonsense that all allergies are due to proteins, but that’s simply not true. People have allergies to metals, salts, lime (the chemical, not the citrus), etc. Be careful when you’re writing these things for public consumption.
