Answer 1

Because when your mother eats food, that food gets totally destroyed. It gets dissolved in acid, it gets broken down by enzymes. The proteins and molecules that cause the allergic reaction don’t survive being eaten.

So if you are in the womb, and your mom eats peanuts, all that is going to make it from the peanuts to the baby is some of the simple sugars, fats, and amino acids that have been totally broken down.
