What percent of all humans are allergic to anything?

Funny thing about allergies, you can start out with none, then develop some, and visa-versa

Do yo mean what percent of all humans are allergic to everything?

I don’t know how many people are allergic to everything. I’ve only met one.

I met a man about 40 years ago who told me that he is allergic to everything. He got discharged from the Army due to his allergies and didn’t last long working at KMC (where I worked as a cook). The skin all over his body turned red and swelled up from the flour with the eleven herbs and spices.

@Zaku That link is fantastic! It answers the question perfectly!

@LuckyGuy Thanks. I probably should have labelled it world-wide allergy statistics .

Years ago I watched Anderson Cooper do a report about this fantastic peanut butter like nutritional food that brings infants and children back from the brink of death from mal nutrition in parts of Africa. At one point Cooper asked one of the doctors what happens if one of the children is allergic to peanuts? She said they don’t see food allergies in developing countries like they do in industrialized countries. Here’s a link if your interested. https://youtu.be/M-qkTmHqW5k she says it around minute 8:30, but you might like watching the whole thing even though it’s a little off topic.
