NCT ID NCT06260956

First seen Jul 14, 2026 · Last updated Jul 21, 2026 · Updated 4 times

Summary

This study investigates whether a mother's consumption or avoidance of peanut and egg during pregnancy and breastfeeding influences her baby's risk of developing allergies to these foods. Pregnant women are assigned to either eat or avoid peanut and egg from 27 weeks of pregnancy through the first four months of breastfeeding. The main goal is to see if this dietary approach reduces the chance of the baby becoming sensitized to peanut or egg by four months of age.

Active substance
maternal consumption or avoidance of peanut and egg during pregnancy and breastfeeding
What this could lead to
If it works, this could point toward a simple dietary guideline for pregnant and breastfeeding mothers to help prevent peanut and egg allergies in their babies.
What could go wrong
This is an early-stage study with 500 participants, so results may not apply to all populations. It only measures sensitization at four months, not long-term allergy outcomes.
