The National Institute of Allergy and Infectious Diseases (NIAID), the lead institute at the National Institutes of Health for food allergy research, is pleased to commemorate Food Allergy Awareness Week from May 9–15, 2010. First established in 1997 by the Food Allergy and Anaphylaxis Network (FAAN), a patient and family advocacy organization, this week is set aside each year to focus public attention on this growing health problem. FAAN’s theme for this year, Respect Every Bite, reminds us of the daily threat faced by people with food allergy, as exposure to even trace amounts of allergenic foods can cause allergic symptoms.
