Early Colostrum Feeding May Lower Peanut Allergy Risk in Infants

New research indicates that infants who are exclusively fed colostrum, the nutrient-rich first milk produced within the initial 72 hours after birth, have a significantly reduced risk of developing peanut allergies by the age of 12 to 18 months. This study, conducted by researchers from The Kids Research Institute Australia and The University of Western Australia, found that these infants are five times less likely to develop any food allergies and eleven times less likely to develop multiple food allergies such as eggs or cow's milk, compared to infants who received formula during the same early period.

The study analyzed data from 666 infants participating in the ORIGINS cohort, Australia's largest ongoing birth study tracking 10,000 families from conception through early childhood. Researchers reviewed hospital records to determine feeding practices in the first three days of life and collected allergy data from pediatric visits at 12 to 18 months.

Results showed that more than half of the infants had received formula supplementation during the first 72 hours, classified as partial colostrum feeding. These infants had a markedly higher likelihood of developing peanut allergies and multiple food allergies later in life. Conversely, infants who received exclusive colostrum (ECF) demonstrated a protective effect. Notably, infants who received nine or more colostrum feedings per day appeared to be fully protected against peanut allergy.

Lead researcher Professor Valerie Verhasselt emphasized that exclusive colostrum feeding acts as a primary preventive measure against food allergies. She highlighted that while early peanut introduction is a strategy to reduce allergy risk, ensuring optimal colostrum feeding in the initial days might offer more profound protection, especially for those at higher risk.

The findings suggest that healthcare providers should support parents in maximizing colostrum intake and following current guidelines regarding early allergen exposure. For infants who receive partial colostrum, increasing the volume and early introduction of allergens could help mitigate allergy development.

The researchers advocate for wider awareness and education about the benefits of colostrum, empowering parents and healthcare providers with evidence-based strategies to prevent food allergies from infancy. Further research is needed to refine recommendations and implement effective early-life interventions.

This groundbreaking study underscores the importance of early feeding practices and provides new insights into allergy prevention during a crucial developmental window.
