If you’re not allergic to nuts or peanuts, eating them while you’re pregnant may lower your baby’s risk of having those allergies.
Researchers studied roughly 8,200 children born between 1990 and 1994. Among mothers who were not allergic to nuts, those who reported consuming nuts the most often (at least five times a week) during—or shortly before or after—their pregnancies had a 70 percent lower risk of having a child who was later diagnosed with a nut or peanut allergy than those who consumed nuts the least often (less than once a month).
What to do: Don’t avoid nuts or peanuts while you’re pregnant in order to lower your child’s risk of an allergy. Exposure to nuts in utero may protect against allergies.
