A food allergy is an immune system response to a food that the body mistakenly believes is harmful. Chemicals released by the immune system to protect the body trigger allergic reactions — varying widely from mild rashes to life-threatening anaphylactic shock. Often difficult to diagnose, food allergies can be lifetime afflictions — with no treatment other than avoiding the offending food. Dealing with Food Allergies presents up-to-date information on current diagnostic methods and treatment options. An authority on food allergies and intolerances, the author describes the effects of food allergies on the skin, mucous membranes, and respiratory and digestive tracts; discusses treatment by allergists and other healthcare professionals; and empowers readers to manage their food allergies. Illustrations, charts, and tables are included.
