Basic, general question about reds

[Kcwhippet]

T, My post comes not so much as a layperson advising a medical opinion as much as one who has done a fair amount of research into the subject. Approximately 10% of the population is asthmatic and about 5% of that fraction are sensitive to sulfites. The senitivity is manifest by respiratory problems, not by a rash. To be truly certain that it may be sulfites that are causing the boss' rash would indeed take a medical professional. However, it's simply not true that wines made and consumed in Europe have less sulfites than those same wines exported to the U.S. Also, I find it dificult to believe that there's some mysterious ingredient added to red wines made in the U.S. that's linked to his rash. I have to believe there's another lifestyle factor not yet explored that's causing the rash.
