A review of the medical charts of peanut-allergic patients seen in an academic allergy clinic between 2000 and 2006 showed that the median ages of first peanut exposure and reaction were 14 and 18 months, respectively. In 1995 the median age was 22 months, and in 1997 the median age was 24 months in a similar population in another such clinic. (Green TD et al: Pediatrics 2007;120:1304).
