Today I read about a syndrome I have never heard of. This post is a great explanation of Oral Allergy Syndrome on Celiac and Allergy Adventures. It is interesting information worth checking out. Apparently, some immune systems (usually those belonging to people who already suffer from seasonal allergies and other allergies) view the proteins of certain foods like like a foreign body. They often experience symptoms like an itchy mouth, ears or throat. According to research as many as one in three allergy sufferers experience this phenomenon. In the past, I thought this was always due anaphylaxis.
