I prefer to put the horse before the horse....and see where it
takes us and then maybe plot the trail. :-)

Consider pre extensive travel and trade cultures. They were
trapped in their climate, physical environment, local foods,
technology and degree(s) of tradition complexity (maybe throw
religion in here).

So lets say they were operating to a certain norm. Somebody
(maybe an explorer) introduces a new food, a spice or even some
new technology. It would take some time for things to diffuse
through the society. Granted, some of the diffusion might be
related to the "Jones" complex but for most part the cost (not
necessarily money) would restrict it's dispersal, unless of
course there was some positive benefit. Maybe a food is better
for the effort to produce it. Maybe a spice not only adds flavor
but has a slight improvement in constitution.

Also consider immigrants. They tend to use traditional foods as
much as they can. Why? Because they have a level of control
based on use (trial and error). As soon as they sway, control is
lost and if they do not regain control, well you know the rest
of the story. Never mind that many foods not only are constantly
changed but little weight is given to nutrition. Marketing and
sales are the #1 factor. Backyard garden anyone?

I don't think anyone has the magic bullet to all our nutritional
problems. A relevant(whatever makes one functional) varied diet
of unprocessed foods is probably the way to go while reducing
excessive toxic substances. Folks keep telling me, "listen to
your body". Who has the time ? :-0
