There was some discussion recently about buckwheat.  --Received this and
thought I'd pass it along.

Digestion resistant buckwheat proteins.

Buckwheat is becoming popular in many countries as a health food and the
incidence of buckwheat allergy is increasing in Asia. The ingestion of small
amounts sometimes provokes an anaphylactic reaction. However, it remains
controversial which is the major allergen responsible for such reactions.

This study has isolated a 16-kD buckwheat protein which is resistant to
pepsin digestion and appears to be responsible for Immediate
Hypersensitivity Reactions (IHR) including anaphylaxis, while the
pepsin-sensitive 24-kD protein was responsible for CAP-FEIA but not IHR

Pepsin-Resistant 16-kD Buckwheat Protein Is Associated with Immediate
Hypersensitivity Reaction in Patients with Buckwheat Allergy.
