Pregnant mothers who consumed peanuts, peanut butter, and tree nuts gave birth to children who had fewer allergies. Offspring of mothers who ate 5 or more servings of nuts per month experienced 66% fewer nut allergies versus those whose mothers ate nuts less than once per month. It appears that early allergen exposure increases tolerance and lowers risk of childhood food allergy.
PositiveTip: Mothers-to-be should feel free to consume nuts.
