Peanut butter in pregnancy, for women who were not allergic to peanuts, actually may help prevent peanut allergies in children. Since peanuts and peanut butter are good sources of protein, this may be a healthy snack for you during pregnancy. Many women also find peanut butter and jelly to be a comfort food. This can be a relief to many PB&J fans. If you or a family member have food allergies, you may wish to discuss your dietary habits with your allergist.
