The study quoted cites undiluted evap milk as the abm.  This is MUCH more
overconcentrated than just changing 20cal commercial abm into 24cal.
 Besides, evap milk and cow's milk have much higher protein, sodium (salt)
than commercial abm anyway.  I still don't have anymore info about 20 to 24
cal change, but citing a ref confusing evap milk with commercial abm isn't a
good idea.  I'm old enought to have been working when evap was in common use
years ago; the commercial abm companies would think that this article was
great for THEIR cause, as they always marketed their product as being more
like bm and evap milk as the only "bad guy."
