I’m 80....in my whole life..I haven’t met anyone that has peanut allergies.
Maybe because PB&J was a staple when I was a kid...and still is in a lot of families.
I never saw or even heard of autism until I was in my 30s or 40s.
I was same way until I had 2 out of 4 with nut allergy. Sure it was new vaccines and schedule.
I wonder how much of the modern peanut allergies we never heard of growing up is connected to pesticides used on peanuts.
