When Were YOU Born?

An article in the NY Times online is headlined thusly:  Really? Celiac Disease is Influenced by Season of Birth.  It concludes, not surprisingly, that there are studies suggesting that the season of birth may influence incidence of celiac, though more research is needed.  The article cites to three studies -- one recently published -- that have found a correlation between spring/ summer births and an increased incidence in celiac.  One theory about the correlation is that typical introduction to gluten occurs around 6 months and, in babies born in spring or summer, that coincides with the winter and an increase in colds and flus.  Another theory is that vitamin D exposure may play a role.  I am clearly no scientist and these theories seemed truly odd to me -- how does it occur to someone to investigate this??   However, I am loving that studies are being conducted.  It gives me hope that there may be some conclusions drawn during my lifetime.  Perhaps even a way to prevent it.
