Does anybody even know what gluten-free means? Where was “gluten” in the 80’s? Where were peanut allergies in the 70’s?

Your ignorance doesn’t make any of that true.

My mother’s best friend in school died of anaphylaxis, at 14, in the 1950s. Coeliac disease – first described by Areteaus of Cappadocia 2,000 years ago – was linked to gluten during WWII. One of the Pharaohs died of an allergic reaction to a bee-sting. A physician, John Bostock, characterised hayfever in 1828.

Incuriousness puzzles me. When I realise there’s something I don’t understand, I find out about it. Why do you, instead, post insincere rants disguised as questions on Quora?
