[Ron] We have thousands of years of history and religious indoctrination
that favors eating grains. Most of the last four or five generations have
been taught since kindergarten, complete with food guide pyramids on our
classroom walls, that grains are very healthy foods. 

You are right that a few celebrities and their trainers are not going to
change current eating habits, but I believe that major changes can be
brought about through changing the propaganda machine. Schools might be a
good place to start.
