sulfite/sulfur allergy causing migraine headaches
ALLERGIC to sulfur dioxide- and it causes me migraine headaches.. I found out by eating fresh grocery grapes. I may also be allergic to, and/ or instead of sulfur dioxide, which is sprayed on the grapes to preserve them, it could be the naturally occurring sulfites that grapes produce after being picked. Although some grapes after being soaked in white vinegar to remove the natural preservative sulfur dioxide did not give me a migraine. So, I'm not sure if it's a type of grape that makes more sulfites as it ages on the vine and after picked, OR if it is sulfur dioxide. I just do not eat fresh grapes anymore.
