To me, nutrition means more than just food.  It means nutrients.
The toxemia theory means disease is a vicarious process of removing toxins,
or in the case of organic disease adaptation to toxins that are too
difficult to remove.  I'm not saying the toxemia theory is false, only
incomplete.  It explains some diseases.  Perhaps it has a hand in explaining
all diseases at least partly.  But tell me, where in Tilden's writings or in
Shelton's writings or in Zovluck's writings or in the writings of any
toxemia theory writer do you find the following information?  Or how would
the following information fit into the toxemia theory?

-- Deficiency of biotin:
  dermatitis, eye inflammation, insomnia, loss of hair, loss of muscle
control, muscle weakness
