Thus,

of

does
not
require

to
be
included
in

equation.
It
should
be
noted
that
converting
these
intake
rates
into
units
of
g/
day
by
multiplying
by
a
single
average
body
weight
is
inappropriate,
because

were
indexed
to

However,
if
there
is
a
need
to
compare
the

to

of

a

and
the
average

should
be

because
the

well
as

The
advantages
of
using
the

are
that
the

expected
to
be
representative
of

and
that

at
the
time
the

was
conducted
for
this

and
should
reflect
recent
eating

in
the
United

The

includes
three
years
of

combined.
However,
the
1989­
91
CSFII
data
are
based
on
a
three

survey
period.
Shortterm
dietary
data
may
not
accurately
reflect
long­
term
eating
patterns.
This
is
particularly
true
for
the
tails
of
the
distribution
of
food
intake.
In
addition,
the
adjustment
for
including
mixtures
adds
uncertainty
to
the
intake
rate
distributions.
The
calculation
for
including
mixtures
assumes
that
intake
of
any
mixture
includes
grains
in
the
proportions
specified
in
Appendix
Table
9A­
1.
This
assumption
yields
valid
estimates
of
per

consumption,
but
results
in
overestimates
of
the
proportion
of
the
population
consuming
total
grains;
thus,
the
quantities
reported
in
Table
12­

should
be
interpreted
as
upper
bounds
on
the
proportion
of
the
population

Although

the

for

on

(

As

When

increased
by
106
percent
and

respectively.
However,

has
remained
fairly
constant
when
comparing
values
from
1989­

with
the

The
