The American Academy of Pediatrics recently published updated guidelines on the topic of maternal and early infant diets for the prevention of asthma, allergic rhinitis, dermatitis, and food allergy (atopic disease). The review of research studies concluded that the early introduction of appropriate forms of peanuts (such as ground peanuts or peanut protein) may prevent peanut allergy. It is not recommended that mothers change their diet during pregnancy or while breastfeeding to prevent atopic disease. It is also not recommended to delay the introduction of high-allergy foods such as eggs, fish, and peanuts, as there is no evidence that such a delay would prevent atopic disease. Researchers note that it is still difficult to draw firm conclusions about the prevention of atopic disease through change in diet early in life.
