failure to grow, and old age follow when
food Is poor in vitamin G.
What foods are rich in it?" DR..
Sherman was asked.
MILK" he replied, which is the usual
answer of the dietitian when asked
concerning vitamins, since the gift of
the COW appears to contain them all.
But DR.. Sherman didn't stop there.
Milk, green leaf vegetables, eggs, and
probably lean meats appear to be an
excellent source of this vitamin," he
said. Whole grain cereals contain
some vitamin g, but should be supple
mented by milk"
DIR. Sherman also pointed out that
vitamin A, fat soluble vitamin, also
was highly important to nutrition and
health. Vitamin A exists in milk, but
ter. egg fats, cod liver oil, green leaf
vegetables and other things. Milk, cod
liver oil, and egg yolks also contain
vitamin D, the sunshine vitamin. Asked
whether scientific diet actually could
prolong life and energy to any per-
ceptible extent, DR.. Sherman said that
1t certainly could, If you would under
stand that he was talking Of the average
and not the Individual
Length OF Lie Extended.
"The length Of human life has been
extended from an average of around 80
to an average of around SO in the last
three generations" he said. But what
has brought up that average is the les
sened death rate among babies and
young children. A larger proportion of
the kids come through; but the life ex-
pectation Of a grown person Is still
around 10, the old three score years
and ten.'
THAT doesn't mean, naturally" went
on DR.. Sherman, that a number Of
persons do not live to a great age. They
do. You can look about and pick prom
inent examples: but am talking aver
ages, what in base bail you would call
team averages, not individual batting
figures. And" said the Columbia pro-
lessor, experiments indicate that pres
ent knowledge permits an increase Of
10 per cent"
Gould you take person who has
lived say half of his allotted three score
and ten years and, by proper feeding.
prolong his ife?"
II think that, barring accident or
epidemic" replied DR.. Sherman, you
| could give him more than an extra
year or two. And, If you took him as
baby, you might add quite number Of
years to the span Of his natural life."
you mean that, II ordinarily the
could perhaps keep hin going till 10
or more? Or. if his natural span was
100. you could lengthen it perhaps
to 110?"
"Yes," said DIR. Sherman, "that's
about it: but again remember that I
am talking averages. And also con-
slider that in the case of rats, which
we use for experiment because they
have a physical mechanism resembling
control from birth to death. The rat
can't get out and go off his diet, or
subject himself to unusual strain. But
I do think that, under average condi-
tions and ordinary circumstances, even
the individual can increase his health
and vigor and prolong his life by proper
and balanced diet"
Teaching of Dietetics.
DR.. Sherman said that much now
was being done to teach dietetics in
had in schools what they called Cook
ing classes" These became classes in
domestic science" and now that course
Is referred to as home economics" The
doctor has just rewritten, for the fourth
edition, his own book on chemistry and
nutrition. Books he recommends are
the Willard-Gille 'FDietetics for High
Schools" and Mary S. Roses Feeding
a Family" and Foundations of Nutri-
ton"
In case vitamins B and C appear TO
have been neglected in this conversa-
ton, it might be well to remind readers
that vitamin B is good for nerves and
neuritis, and 1t is found in whole grain
cereals, general roughage. and many
vegetables; while vitamin C, which adds
stamina and vigor. lessons irritability
and promotes growth, is to be found in
oranges. lemons, grapefruit. tomatoes
and raw onions.
Vitamin E scientists appear to pass
over, and vitamin they scarcely men
tion. But perhaps they consider A and
G plenty for all present purposes. They
will enable one to live long enough TO
find out about the others.
