Are
we
what
we
eat
?
Maybe
you've
noticed
that
your
taste
has
changed
or
that
you
are
eating
different
foods
than
a
few
years
ago
.
If
you
ever
wonder
why
,
here
are
some
answers
.
What
controls
what
we
eat
?
Some
people
might
point
to
a
routine
as
being
of
high
importance
.
My
father
,
for
instance
,
after
the
death
of
my
mother
,
ate
by
the
clock
?
7
:
30
a
.
m
.
was
time
for
breakfast
,
12
:
00
p
.
m
.
time
for
lunch
,
and
so
on
through
the
day
.
.
.
week
in
,
and
week
out
.
The
time
never
changed
,
though
the
decreased
in
size
as
he
aged
.
We
never
really
worked
out
if
this
routine
was
a
result
of
his
army
background
,
or
just
a
way
to
make
sure
he
would
never
forget
a
meal
!
Other
people
desire
food
because
of
a
sight
or
a
smell
,
and
there
are
many
other
food
cues
,
both
social
and
cultural
.
The
relationship
that
we
have
with
food
is
complicated
,
and
hence
,
dividing
the
population
simply
into
those
that
live
to
eat
and
those
that
eat
to
live
may
be
entertaining
but
not
very
educational
.
Recent
research
has
focused
on
the
way
our
changes
with
advancing
years
.
Understanding
the
nature
of
these
changes
can
help
us
tackle
different
issues
,
such
as
waste
,
,
obesity
,
and
possibly
,
dementia
.
During
our
early
years
,
we
have
little
control
over
what
we
eat
and
most
parents
see
it
as
part
of
their
role
to
provide
their
child
with
a
varied
diet
.
However
,
recent
advice
appears
to
suggest
that
some
measure
of
control
needs
to
be
,
particularly
in
relation
to
the
common
'clear
your
plate'
.
Conversely
,
in
the
second
decade
,
when
young
adults
are
often
given
more
freedom
of
choice
,
they
often
make
the
wrong
choices
driven
by
peer
pressure
,
advertising
,
and
time
pressure
?
often
resulting
in
unhealthy
consequences
.
As
we
enter
our
20s
and
30s
other
factors
come
into
play
,
like
personal
relationships
,
living
away
from
home
,
college
or
work
stress
?
all
these
factors
affect
our
appetite
and
therefore
,
our
food
intake
.
Different
foods
send
different
signals
to
the
brain
,
which
in
turn
,
makes
us
feel
either
satisfied
or
still
hungry
.
Consuming
foods
high
in
protein
,
water
,
or
fiber
makes
us
feel
fuller
for
longer
,
limit
our
food
intake
,
and
lower
the
risk
of
weight
gain
.
The
fifth
decade
,
according
to
many
doctors
is
the
critical
one
?
our
'last
chance'
to
make
the
right
lifestyle
choices
.
If
you're
a
smoker
,
have
an
unhealthy
diet
,
or
consume
an
excessive
amount
of
alcohol
,
this
is
the
time
to
change
before
the
of
the
illnesses
associated
with
these
behaviors
appear
.
After
passing
the
age
of
50
,
people
begin
to
lose
muscle
mass
naturally
,
but
limiting
your
exercise
and
consuming
too
little
will
accelerate
this
decline
.
Unfortunately
,
there
are
currently
too
few
snack
food
products
that
have
been
designed
to
specifically
meet
the
needs
of
older
adults
.
As
we
reach
the
later
decades
of
life
,
it
is
necessary
to
recognize
that
social
factors
can
affect
our
appetite
.
The
loss
of
a
partner
or
separation
from
family
members
can
mean
eating
alone
,
removing
one
of
the
pleasures
of
a
mealtime
.
Other
effects
of
old
age
such
as
reduced
taste
,
or
dental
issues
can
interfere
with
the
desire
to
eat
.
In
these
years
,
considering
that
adequate
nutrition
is
even
more
important
to
health
,
eating
may
become
a
rather
than
a
joy
.
Food
is
not
just
fuel
and
the
longer
you
regard
it
as
a
cultural
and
a
social
experience
,
the
healthier
you
will
remain
.
