That’s different - Northern European tolerance to lactose is actually a mutation/adaptation.
There’s probably some processed food or medicine that triggers these severe allergies in babies.

And the allergies can't also be a mutation/adaptation?
Wouldn't some "processed food or medicine that triggers these severe allergies" be a "mutation/adaptation"? I'm confused on the distinction you're trying to make it it's not "Americans are bad haha".
My mom used to study this stuff, and her conjecture was that the “low fat” craziness happened around the same time as people being unable to cook for themselves.
When you eat your Trader Joe’s frozen whatever, it is often fortified with soy or pea proteins and different stuff to preserve taste and appearance. Chain restaurant stuff is similar.
Once in awhile, no big deal, but many people are incapable of cooking. My local library has a class in cutting onions and other vegetables booked out till April. Lots of kids grow up with soy formula and frozen chicken nuggets. Pre 1990, no human ate that stuff.
The lactose tolerance unlocked major food group. Allergies lock people out of staples. So we have huge interest as a species to figure out why they appear and prevent them.
Genetic changes cannot explain the dramatic rise in allergies (not just food-borne) over the last few decades.
