So we have to consider proper relations of copper too.
You say the relation must be about 7:1.
Which deviation if this are usual? In which food items?
Should/can zinc or copper be higher?
I would suggest a USDA database scan, sorted by relation of
zinc to copper. So we could select out food items with
unfavourable ratios.
Norm, could you run such one?
