The million dollar question of course is, small exposures or delay any exposure as long as possible?
My instinct like I'm guessing most of yours is to avoid gluten until the kids wind up at a birthday party or something. This review paper seems to suggest otherwise...
A few excerpts:
This specific study examined the association between cereal-grain exposure (wheat, barley, rye, oats) in the infant diet and development of wheat allergy in 1,612 children from birth until the mean age of 4.7 years. One percent of these children developed wheat allergy. Surprisingly, those who were first exposed to cereals after 6 months of age had an increased risk of wheat allergy compared with children first exposed to cereals before 6 months of age
a large, population-based, prospective birth cohort study conducted in Germany, showing that delaying solid food introduction beyond the 6th month did not offer protection toward atopic dermatitis or atopic sensitization.
the DAISY study, conducted in a cohort of children at risk for IDDM followed prospectively from birth for a mean of 4.7 years. This study documented that exposure to cereals (rice, wheat, oats, barley, rye) that occurred early (<3 months) as well as late (>7 months) resulted in a significantly higher risk of appearance of islet cell autoimmunity compared to introduction between 4 and 6 months.
Interestingly, this study also showed that if cereals were introduced while the child was still breastfed, the risk of islet cell autoimmunity was reduced, independently of the age at introduction of cereals.
To test this hypothesis, several observational epidemiological studies have been conducted and reviewed in a recent meta-analysis. All of them, with only one exception found in a small study, showed that introducing gluten during breastfeeding reduces the risk of development of celiac disease.
