Abstract:
Alongside with the globalization of the Danish kitchen and the introduction of a larger number of commercial food items containing buckwheat, buckwheat allergy no longer seems to be a rare disease in Denmark. Since buckwheat allergy can cause life-threathening reactions, it is important for medical doctors to be aware of this allergy. Reliable serological tests showing specific IgE to buckwheat protein 2S albumin (Fag e2) are available in most countries. Three patients with anaphylactic reactions due to buckwheat allergy are presented.
