CHILDREN NEED
BUTTER & EGGS.
Continued from Page i


right when it was written, but it needs
a new edition We did not know until
two years ago that there was some
thing about certain fats which is in
dispensable to the young, growing ami
mai and without which his nutrition
must fail The fats of milk and eggs
and of certain organs are particularly
rich in this substance and while it is
found in the plant kingdom it is always
in amounts too small to supply the
needs of a rapidly growing animal, at
least SO far as we know at present.
The point which | wish TO emphasize
here is that we are not to speak of fats
in our discussion of nutrition without
recognizing that all fats are not OF
equal value to the animal during
growth. because they have about the
same energy value and are about
equally well digested and absorbed.
BY the simple experiments | have de-
Scribed this is made clear. | wish also
to point out that thousand years OF
painStakng effort III the study Of nu
triton problems by the regular pro-
cedure Of the animal huSbandryman,
would never have disclosed this pecul
Jar grOwth-prOmOting power of certain
fats as cOntrasted with others. Here
is q something which is Indispensable
for the growth or prolonged well-being
of the young animal, and without
which no amount of protein, palatabil-
ity or digestiblity will produce IA
ton which will suffice. Yet this Who'll
ly unsupported substance would never
have been discovered without expert
mentS of the kind described above i'll
which purified fOodstuffs were en-
ployed instead of mixtures of naturally
occurring ones.
Butterfat VS.. Oleomargarine
| have been repeatedly asked if this
story of the peculiar food properties OF
butterfat as cOntrasted with the body
fats Of animals is not to be construed
as the funeral Grafton of the butter
substitute. In the past the butter
substitute man has argued that one fat
yields as much energy as does any
equally well digested and absorbed,
and that when he makes a product
which is as palatable as butter, he has
something just as good as butter i'll ev-
cry respect. and at Il great saving III
expense.
My answer to this question is as fol-
lows: The butter substitute. contain
ing Il considerable admiXture of the
body fats of the animals, is not equal
in its physiological properties to an
equal amount of butter, although 1t
may possess as much energy and equal
digcstibility AS an energy food it
may be Just as good as butter, but III
the peculiar growth-prom0ting power
we have been discussing, butter is low
cred in value in so far as it is diluted
with animal or vegetable fats. Among
the ordinary human foOdstuffs the
sources of the unknown substance in
diSpenSable for growth are eggs. milk
and meats. Meats do not furnish so
much as do either eggs or milk. All
other human foods either 90 not FUR
niSh this substance at all or contain
entirely inadequate amounts OF it. 1t
is easily possible and practicable to
give the young child what he needs of
this substance in the form of milk and
eggs, and still allow him to eat Il but
ter substitute ION his bread. At least
| believe there is no doubt that this
can he done There are no substitutes.
however. for these two kinds of foods
for the growing young.
