In a recently published article in Pediatrics on the Swedish coeliac disease 'epidemic', it is suggested that the gradual introduction of gluten-containing foods from 4 months of age, preferably while breastfeeding is still ongoing, is favourable for the prevention of coeliac disease. This stirred up the discussion about the timing of introduction of gluten to the diet of infants in the Netherlands, where gluten-containing foods are mostly introduced from 6 months of age onwards. The retrospective character of data collection, however, has to be taken into account when interpreting the Swedish study. Future results of prospective studies on gluten introduction and coeliac disease, such as the PreventCD family study (www.preventcd.com), should provide the information necessary for deciding on a change in the Dutch guidelines for the introduction of gluten to the diet of young children.
