Abstract

The gastrointestinal tract, in addition to its main function as a digestive organ which absorbs nutrients, provides a barrier against the entry of macromolecular antigen. This barrier is incomplete for there is now ample evidence that antigen crosses the gastrointestinal mucosa in all healthy individuals(1). The amounts which enter the circulation are insignificant nutritionally but are sufficient to immunise since antibodies to food proteins may be demonstrated to low titres in most healthy people(2). These antibodies are apparently not damaging and hypersensitivity reactions to food proteins are uncommon.
