I think that more food probably does result in more milk production up
to a certain point.  But if the mother's diet is adequate to begin
with, increasing calories will not makea difference.  Perhaps eating
better results in the mother feeling better and thus the *impression*
that her milk supply is greater.

By the way, nipple stimulation alone does *not* increase milk supply.
It is removal of milk from the breast which increases milk supply.
That is why babies can nipple at the breast all day, not gain weight,
and the mother's (and their "helpers") not understand why the
production seems inadequate.
