Doug, if people automatically refrained from eating all the foods that
they MIGHT be sensitive to, they wouldn't have anything to eat. It
should be implied that no one should eat something that he or she is
actually sensitive or allergic to, but there's no reason beyond that
to avoid foods that contain nitrates and nitrites, for example, a fear
of cancer, heart attack, etc. In fact, doing so may actually be
counterproductive to one's health.

Paleolithic plans use rules that if anyone is intolerant of a food it's
to be avoided. The list of foods that remain is large. Each
paleolithic plan has slightly different rules resulting in slightly
different lists but the result is the same.

Atkins starts with a list of allowed foods. On that list are eggs and
dairy which are a major loophole to the principle of starting with foods
that have extremely low chance of having intolerance reactions.
Starting from the list of allowed foods for Induction ingredients are
supposed to be added one by one and tested in the
eliminate-and-challenge style. Few follow that part of the directions
but it does appear in the directions.
