hi iceskate, which heavy metals were tested iima? also did they give you the results with units, or just tell you everything was 'normal'?
pls be aware that 'normal' is a statistics normal ie data on enough different people that it describes a bell curve. ie lowest to highest values from a group that is large enough to represent everyone.. including sick ppl. somewhere within 'normal' is a smaller range representing healthy people.
fyi the inability to taste could be a red flag re zinc status. did they test zinc by chance?
this is only case study, and an odd one at that, however:
Hypozincemia, Ageusia, Dysosmia, and Toilet Tissue Pica
