A recent study (CA Aronsson et al. Clin Gastroenterol Hepatol 2016; 14: 403-09, editorial 410-12) suggests that how much gluten is given may be another important factor rather than looking at the timing with regard to the development of celiac disease (CD).
In this 1-to-3 nested case-control study with 146 cases of CD and 436 controls, the authors indicate that a larger intake of gluten than controls increased the likelihood of celiac disease. Specifically, children receiving large amounts of gluten (>5 g/day) during their first 24 months had a 2.6-fold increased risk of CD compared to those who consumed lower quantities.
The associated editorial notes that the total amount of gluten intake was only marginally increased in CD cases versus all control patients (OR 1.05) and that the association was decreased when individuals with first-degree relatives with CD were excluded. In addition, this high consumption increased the risk after the first 2 years of life, rather than during this period of high consumption.
Does this make sense? Not to me. These findings need to be replicated in other studies to determine if gluten exposure is like Goldilocks: too little, too much –>just right.
My take: For now, I think sticking with the timing of gluten exposure (recommended at 4-6 months) rather than the quantity is worthwhile.
