Mary:
  Have you heard of French clay?  It is ingested and absorbs all sorts
of yucky things. I have a book written in 1974 called "Our Earth Our
Cure".  Translated by Michel Abehsera.  You might find some helpful
information. Try not giving your son any fruit.  I love fruit but cannot
handle the sweet carbs.  I finished my new copy of Neanderthin yesterday
and ate a banana and an apple.  Today I am starving for sweets.
