"Corn is not one of the common “Big 6” allergens that are felt to worsen eosinophilic esophagitis . . ."
". . . the fact that your patient has a positive skin test to corn or to any other food would not automatically suggest removal of that food from their diet."

In response to Dr. Lieberman's statement, I sent him the following documentation:
"Maize/Corn," Thermo Scientific, 2012
"Maize has been implicated as one of the causative foods of eosinophilic esophagitis, a disorder with symptoms suggestive of gastroesophageal reflux disease but unresponsive to conventional reflux therapies (58)."

Maltodextrin, Wikipedia
"Maltodextrin can be enzymatically derived from any starch. In the US, this starch is usually corn; in Europe, it is commonly wheat."

My Personal Story:
From 2008-2011 I suffered daily reactions to nearly everything I consumed--it felt like I was being poisoned. Since I did not realize that I had an allergy to corn (ubiquitous), I did not take an antihistamine to resolve my symptoms; and these reactions lasted for up to 7 hours every day. When I was finally referred to an allergist, I only tested at 1+ for corn per skin-scratch testing; yet my reactions to corn/corn derivatives are severe; e.g., I experienced one of my worst reactions after consuming a small amount of iodized salt with corn-derived dextrose, and my reactions to corn-derived citric acid and corn-derived ascorbic acid are just as severe.
Therefore, no medical professional should ever encourage anyone to consume their allergen in any amount, unless they are in the presence of their physician. Based on the personal testimonies I read on a daily basis--particularly from those who are anaphylactic to corn, anything derived from corn can cause an allergic/anaphylactic response.
STRICT AVOIDANCE OF ALLERGEN IS ADVISED:
Food Allergy & Anaphylaxsis Connection Team (FAACT)
"Although food allergy desensitizations are being studied, these are not yet proven treatments, so strict avoidance is the only way to prevent an allergic reaction."
"Trace amounts of an allergen can trigger an allergic reaction in some individuals."

"Patient education: Food allergy treatment and avoidance (Beyond the Basics)," Scott H. Sicherer, MD, FAAAAI, UpToDate, April 25, 2017
"People with food allergies can have serious or even life-threatening reactions after consuming certain foods. The most important strategy in the management of food allergies is to avoid eating these foods."
December 31, 2017, Notification to American Academy of Allergy Asthma & Immunology (AAAAI):
Since the advice offered by Dr. Phil Lieberman can endanger the lives of corn-allergic patients, I sent a request to the AAAAI to remove this paper from their website.
