and it’s    whiter, because the carotenoid

Nutritional Alteration; Low-Fat Milks   One
nutritional  alteration  of  milk    is  as  old     as
dairying    itself: skimming    off the cream   layer
substantially    reduces     the     fat     content     of  the
remaining    milk.   Today,  low-fat     milks   are
made     more    efficiently     by  centrifuging    off
some    of  the globules    before  homogenization.
Whole   milk    is  about   3.5%    fat,    low-fat milks
usually 2%  or  1%, and skim    milks   can range
between 0.1 and 0.5%.
More    recent  is  the practice    of
supplementing   milk    with    various substances.
Nearly  all milks   are fortified   with    the fat-
soluble vitamins    A   and D.  Low-fat milks   have
a   thin    body    and appearance  and are usually
filled  out with    dried   milk    proteins,   which   can
lend    them    a   slightly    stale   flavor.
