there is a probability that food antigens are recognized.
there are documented tolerance pathways  that operate after ingesting
and there is obvious evidence that some individuals are "allergic" to
some foods

also don't forget that a lack of a recognized response doesn't mean
there is no response, and tolerance is a response too.

this is off the cuff
'cause I don't have available mucosal immunity info
