"...based on Dr. Weston Price's twenty-five years of careful, impeccable
research. He led a 60-man team of researchers whose findings - suppressed
until now rank right up there with the greatest medical discoveries of all
time. This is not the usual medical story of a prolonged search for the
difficult-to-find causative agent of some devastating disease. Rather, it's
the story of how a "cast of millions" (of bacteria) become entrenched
inside the structure of teeth and end up causing the largest number of
diseases ever traced to a single source ... A primitive diet of whole
unrefined foods is the only thing that has been found to actually prevent
both tooth decay and degenerative diseases."
