Lumping all of soy, rice, almond, goat milk as "non-cow" is pretty unfair to goat milk. Does their study indicate all milks in "other" independently showed similar difference in height of 1.5cm? Or are they saying the average for all other was -1.5cm in which case maybe kids on almond milk were -2cm and breast milk +1cm? And goat's milk some third number? My strong hunch is it is the latter in which case the 1.5cm is completely meaningless. Here is another clue, the one example they give of nutritional differences cites soy milk's low protein while failing to mention that goat's milk has more protein than cow's milk. Didn't read the original research but either the research is bad and possibly biased or this is very misleading reporting. [edit] removed mention of breast milk since article didn't say that
