The parents who were instrumental in getting the US government to pass the
Infant Formula Act of 1980 have an interesting point of view on
brand-exclusivity in ABM. Their children were damaged by an exclusive diet of
chloride-deficient formulas.  One told me that if a baby isn't breastfed, the
prudent action is to use several brands per week and even start solids early.
The theory is: allergy aside, each brand has a slightly different
composition, with more of one thing or less of another. By varying brands and
adding other foods, trace elements missing in one would be made up by
another; excesses in a nutrient from brand X might be balanced by less in
brand Y, etc.
Interesting concept, eh?  Sounds logical to me - any dietitians care to
comment?
