“All About Allergies” is the new book by Dr. Zachary Rubin, a double-board certified allergist and immunologist who joins Dr. Sanjay Gupta to break down what distinguishes an allergy from an intolerance, what flags to watch out for before a reaction, and explain what to expect from a trip to the allergist’s office. Plus, Dr. Gupta shares a surprising story about a time he swelled up from eating a mango.
