The PrEggNut Study

Maternal diet rich in eggs and peanuts to reduce food allergies: a randomised controlled trial
The PrEggNut Study
Project Status: In progress
Project administered by: The University of Western Australia

Food allergies now affect more than 10% of children. Recently, babies have been found to be at risk of developing a food allergy even before they start eating solid foods.

This team's earlier work has suggested that babies’ immune responses can be improved by their mothers eating more eggs during the first weeks of breastfeeding.

This research trial aims to determine whether mothers regularly eating more eggs and peanuts during pregnancy and breastfeeding will reduce food allergies in their babies. SAHMRI is looking for people who are less than 23 weeks pregnant to participate in the PrEggNut Study.

Who can take part?

Pregnant women who:

  • Are less than 23 weeks gestation (singleton pregnancy)
  • Have at least two family members (themselves, baby’s father or previous child/ren) with a history of medically diagnosed allergic disease (asthma, eczema, food allergy or hay fever)
  • Are planning to breastfeed for at least four months
  • Do not have an egg or peanut allergy

Serious food allergy reactions, anaphylaxis and food-related deaths have increased over the past two decades. Food allergy is a chronic disease that reduces quality of life, places significant burdens on schools, communities and the health care system at large. Effective prevention strategies in early life are urgently needed.

This randomised controlled trial study design will address an important gap in knowledge. It will provide high quality scientific outputs that progress the field of allergy prevention and will provide a sound evidence base to inform clinical practice allergy prevention recommendations for the role of regular inclusion of traditionally allergenic foods in the maternal diet during pregnancy and breastfeeding.

What does the study involve?

Participants will be randomly assigned to one of two study groups: a ‘standard egg and peanut diet’ group (which is typical for most women) and a ‘high egg and peanut diet’ group. Participants will be asked to follow the diet advice for their group from 22 weeks gestation until their baby is 4 months of age (or until breastfeeding ceases). The outcomes of egg and peanut allergies will be compared in the babies of the two groups at 1 year of age.

Why should you take part?

  • You will receive the most up to date Australasian Society of Clinical Immunology and Allergy (ASCIA) infant feeding and allergy prevention guidelines for introducing solid foods to your baby.
  • You will be educated on recognising the signs and symptoms of an allergic reaction and advice on what to do in such circumstances, consistent with the ASCIA guidelines.
  • If there is any aspect of breastfeeding that you would like more support or advice with, we will arrange a referral to a Lactation Consultant at no cost to you.
  • You will be reimbursed for attendance at the 12-month visit with your child and receive the results of their skin prick allergy test.
  • You will help contribute valuable information that may benefit other pregnant women and their babies in the future.

Who is conducting the study?

The PrEggNut Study is being directed by Dr Debra Palmer at the Telethon Kids Institute in Perth. This is a large, multi-centre study being conducted in Perth, Melbourne, Sydney and Adelaide and is aiming to involve over 2100 participants. SAHMRI is leading the study engagement in Adelaide.
