This study examined 10,907 participants from the Growing Up Today Study 2. Participants were children of mothers who reported their diets during pregnancy as part of the Nurses' Health Study 2. Authors tested the relationship between peanut/tree nut consumption during pregnancy and risk of peanut or tree nut allergy in children.

Key Findings: Peanut/tree nut allergies were significantly lower in the children of 8059 nonallergic mothers who consumed more peanut/tree nut in their peripregnancy diet than those who did not.
