This supplement pusher understandably left out an important study finding --
" Exclusion of supplement users did not affect the results." This is yet
another study supporting the suggestion that a better diet provides benefits
that cannot be obtained froim supplements. It also raises the possibility
that it is not the antioxidant properties of the diet that help protect
against this degenerative disease. Antioxidant intake may merely be a
market for a better diet in other respects.
