There is, and I'm sure that contributes but probably significantly more in babies who've been forced to avoid peanuts.

The advice was literally crazy when my wife was pregnant saying she should avoid peanuts, strawberries etc. even whilst pregnant. I laughed my ass off at it, and told my wife that's the opposite of how allergies work.

My kids have no food allergies.

The kids that have food allergies are always the ones from older parents who panic read parenting books like they're important cause they fucked up their chances at a healthy family by waiting until 35+ to start.
