We keep getting these articles based on 2 peanut studies that specifically only included Jewish children from Israel and England, the ones in Israel had the peanuts early, and the ones in England did not. One study being under 100 children, and one over 1000. Based on these studies Australia changed their recommendations and the number of people introducing their children to peanuts before the age of 1 went from 26% to 85% by 2018. This had _no_ effect on allergy rates to peanuts. They still remain the same.
As an aside, my wife is allergic to peanuts, we have no peanuts in our house, and our kids didn't try peanuts until after the age of 7. None of them have peanut allergies.
