NEJM 9 17 2026 Trial of a Maternal Diet Rich in Eggs and Peanuts to Reduce Infant Allergy

This clinical study investigated whether a mother’s diet during pregnancy and breastfeeding could influence the development of food sensitivities in children with a high genetic risk for allergies. Researchers compared a group of women who consumed large quantities of eggs and peanuts to a control group following a standard diet to see if early allergen exposure via the womb or breast milk offered protection. Despite the intensive dietary intervention, the results showed no significant reduction in allergy ratesamong infants by one year of age. Ultimately, the trial concludes that maternal consumption of common allergens does not appear to be an effective strategy for preventing the onset of these specific food allergies in early childhood.
