Celiac.com 03/30/2016 - New guidelines reverse previous recommendations on infant gluten introduction to prevent celiac disease. What's going on?
Two earlier studies did claim to show that the time of introduction to gluten had an impact on later development of celiac disease. Based on those studies, in 2008, ESPGHAN issued a recommendation to introduce gluten into the infant diet between 4 months and 7 months, and to introduce gluten while the infant is still being breastfed. But since then, two randomized controlled trials have shown that the age at gluten introduction does not affect overall rates, nor does it affect the incidence or the prevalence of celiac disease during childhood.
The latest findings show that "primary prevention of celiac disease through nutritional interventions is not possible at the present time," says Professor Szajewska of The Medical University of Warsaw, the lead author of the new guidelines. These new guidelines say that parents may introduce gluten into their infant's diet anytime between four to twelve months of age, and that the introduction does not need to be made via breastfeeding.
It remains true that, according to study data, earlier gluten introduction does cause the celiac disease to present at an earlier age. However, current evidence indicates that neither breastfeeding, nor breastfeeding during gluten introduction can reduce the risk of celiac disease.
The new evidence shows no difference in celiac disease risk when gluten is introduced while the infant is still breast-feeding, compared to after weaning. Because breastfeeding has many other health benefits, doctors recommend it for all infants, regardless of celiac disease risk.
The updated recommendations are based on studies of infants with known risk genes for celiac disease. However, because parents don't often know this at the time solid foods are introduced, the recommendations apply to all infants.
