Buckwheat allergy can cause severe reactions like anaphylaxis, even in those not allergic to wheat. This study highlights buckwheat as a distinct food allergen, separate from common grains.

Area of Science:

  • Food allergy research
  • Immunology
  • Occupational health

Background:

  • Buckwheat (Fagopyrum schulentum) is a pseudocereal, unrelated to wheat.
  • Buckwheat flour is a common wheat substitute in various food products.
  • Occupational exposure to buckwheat flour can cause respiratory and skin reactions.

Observation:

  • A patient experienced urticaria and hypotension after consuming buckwheat crepes.
  • Skin prick testing showed a strong positive reaction to buckwheat.
  • Radioallergosorbent test (RAST) confirmed high levels of anti-buckwheat IgE antibodies.

Findings:

  • Buckwheat ingestion can trigger severe allergic reactions, including anaphylaxis.
  • The patient had no allergic reactions to wheat, egg white, or milk.

  • No cross-reactivity was observed between buckwheat and wheat allergies.

    • Implications:

    • Buckwheat should be recognized as a significant food allergen.
    • Individuals with buckwheat allergy require careful dietary management.
    • Further research is needed to understand the prevalence and mechanisms of buckwheat allergy.
