If the oral allergy syndrome is due to x-reactions between homologous proteins in ingested food and aero-allergens why aren't food skin tests +?

If the oral allergy syndrome is due to x-reactions between homologous proteins in ingested food and aero-allergens why aren't food skin tests +?

Too complex...?!: The gut is both an immune privileged site and responds adversely (and often unpredictably) to ingested materials (e.g. Bacteria, food, dirt, etc.). There may be too many variables to easily answer your question. A case in point is eosinophilic esophagitis. Sadly, given our knowledge gap, too many patients take too many supplements or exclude too many products for questionable reasons. ...Read more

Are the health food store bee pollen meds just a gimmick for treating allergies?

Are the health food store bee pollen meds just a gimmick for treating allergies?

Yes: The pollens that cause allergies are very small, and carried by the wind. Flowers need bees to cross-pollinate, because the pollen is too big and heavy to be carried by the wind. Since they're not airborne, people can't inhale them and react to them. Thus, the pollens found in bee pollen are not the pollens that cause your allergic symptoms. ...Read more

In food allergic patients a drop of food to which the patient is allergic dropped into the eye can cause chemosis that is marked swelling of the conjunctivitis.
