Area of Science:

  • Immunology
  • Gastroenterology
  • Allergology

Context:

  • Dietary intake exposes individuals to numerous antigenic substances.
  • Normal physiological mechanisms (mechanical, enzymatic, immune) typically prevent adverse reactions.
  • Failure of these protective mechanisms can lead to food intolerance, idiosyncrasy, or allergic reactions.

Purpose:

  • To review the mechanisms, diagnosis, and management of adverse food reactions.
  • To highlight the prevalence and clinical spectrum of food allergies.
  • To emphasize diagnostic approaches and treatment strategies.

Summary:

  • Adverse food reactions affect 1-3% of the general population, and up to 8% of children under three.
  • Clinical manifestations range from gastrointestinal discomfort to life-threatening anaphylaxis.

  • Diagnosis relies on thorough patient history, physical examination, skin tests for immediate hypersensitivity, and specific IgE antibody testing (RAST, ELISA).

    • Impact:

    • Accurate diagnosis and management of food allergies are crucial for patient well-being.
    • Understanding the underlying mechanisms aids in developing targeted therapies.
    • Effective treatment involves strict avoidance of the offending food, rather than non-specific dietary restrictions.
