Single food allergy and reasons for multiple exclusions: A prospective study.

Food Allergies (FA) presents an increasing global challenge, influenced by factors such as genetic predisposition, ethnicity, age, and cultural dietary practices. Patients diagnosed with IgE-mediated FA must adhere to strict dietary restrictions to avoid potential life-threatening anaphylactic reactions. Such restrictions are crucial but come with significant consequences as increased nutritional risks, higher costs for special meal preparations and medical care with potential social and psychological impacts on both the individual and their family The impact of FA on quality of life is frequently surrounded by persistent fear of adverse reactions after consuming certain foods. To better understand the behavior of patients with FA this study aims to explore whether patients with confirmed IgE-mediated FA tend to exclude other foods and to identify possible reasons for such exclusions.
