I read it, but am not convinced. It is possible that the non-whites kids are less likely to have adequate doctor care and less likely to see a specialist (allergist). There may be many reasons such as economic that he didn't even touch on.
Also, many general practice pediatricians are reluctant to prescribe epi-pens. If there is a language problem, there might be difficulty and reluctance requesting one.
Also, the diet of "minority" families that have been in the US for a couple of generations are not that different from Caucasian families.
What about mixed race kids? Mine are part Asian, part Caucasian. Most of the PA kids that I know happen to be Asian.
There are probably many other possibilities, too tired to consider anymore at the moment. Kinda seems like a lazy study.
