Since
nutrition
scientists
are
constantly
making
new
discoveries
,
we
need
to
revise
our
____________________
for
healthy
eating
from
time
to
time
.
However
,
nutrition
is
an
art
as
well
as
a
science
It's
an
art
because
it
requires
creativity
____________________
develop
a
healthy
eating
plan
for
people
who
differ
in
their
food
preferences
,
beliefs
and
culture
,
let
alone
in
their
____________________
needs
according
to
their
genes
and
life
stage
.
As
we
discover
more
about
how
our
genes
and
our
environment
interact
,
it's
becoming
increasingly
difficult
to
provide
a
single
set
of
dietary
recommendations
____________________
will
be
suitable
for
everyone
.
What
we
do
know
is
that
there
is
more
than
one
approach
to
healthy
eating
.
For
example
,
although
this
book

on
a
high
-
protein
eating
plan
,
it
____________________
also
possible
to
lose
weight
healthily
with
a
high

carbohydrate
or
a
vegetarian
eating
pattern
.
What
is
important
is
what
works
for
you
