Good question, I mean how many people were actually feeding Cheeto puffs to their 6 month old before it became a health trend
The peanut allergy hysteria narrative says that I can't eat peanuts on a plane or in a classroom with somebody who's allergic because the mere odor of peanuts might kill them. If there is any shred of truth to that narrative (which I seriously doubt), then perhaps trace peanut dust in a home from adults eating crunchy peanut-based snacks is enough early exposure to inhibit an allergic reaction.
My uncle doesn't topple over dead from the smell of peanuts, but he can't be in the house while peanut butter cookies are baking or he will get a bad/dangerous reaction. I suppose there's likely people with worse allergies than him.
You mean from exposure to other kids?
My guess is through breast milk - which I was wondering about with the study as well; does it make a difference for breastfed babies whether their moms eat a lot of peanuts?
Anecdotal: a pregnant woman ate a lot of the stuff (something similar to Bamba) when pregnant, and I mean a lot. The child was diagnosed with peanut allergy when 1 y.o.
Solution? Peanut microdosing, increasing dose progressively, in few months the allergy was gone.
Anecdote from my partner: Allergies come and go, they're not necessarily permanent even if you don't treat them.
Since no one really knows what causes peanut allergies, it isn’t surprising they come and go without much insight into why.
Mom, dad, siblings. Anyone snacking on it will have it on their faces, finger tips. It'll get on the counters and floor. And find its way on a bottle nipple, blankets, sheets, fingers, etc.
