such oily fish as salmon and sardines.
Eggs and butter are comparatively
good sources, though variable. Liver,
cream, milk and oysters contain a
little. But at best, the quantity OF
this vitamin that can be had in the
common foods under ordinary con-
ditions is not very great.
THERE Is another source OF vita
min d, however, and that Is
sunlight-or rather, the ultraviolet
rays in the sunlight acting upon the
skin either of animals or human
beings. The skin contains substance
which Is changed by the suns ultra
violet rays into vitamin D. SO human
beings and animals that spend a
great deal of their time in the sun
get much of their vitamin D that
way.
"The discovery of these facts had
important results for children. 1t was
known that undernourished babies,
and little children shut of from the
sunshine in city tenement districts
commonly had rickets-a disease of
the bones, which left such children
bow-legged, chicken breasted or
otherwise deformed for life. Milk
helps to prevent this condition, be-
cause of the bone-making materials
Calcium and phosphorrs) milk con-
tains. But milk alone will not do 1t.
Something else is needed, something
to help the childs body use the
bone making materials milk supplies
in other words, vitamin D, which must
be supplied in the children's foods
If they do not get enough sunshine.
Nowadays, therefore. to prevent
rickets, nutritionists say: Feed the
child plenty of milk, plus some good
vitamin D-rich food-for milk ordin-
arily contains only a little Of this
vitamin. Give the child plenty OF out
door sunshine, too. of course.
"QUT what shall be used as food
rich in vitamin D? Doctors and
nutritionists alike have said cod liver
oil, which furnishes the important
whitman A also. and cod liver oil
has become more or less regular
part of the child's diet nowadays,
especially in Winter, when there is
less sunshine and less of the useful
rays in what sunshine there is.
"Other ways of providing vitamin
D in foods have since been discovered.
Cows milk can be enriched with this
vitamin by feeding the COW ''irradi-
ated" yeast. E., yeast exposed to
ultraviolet light to provide it with
vitamin D. Or vitamin D can be
added to the milk in two other ways.
One way is to add cod liver oil extract
to the milk (you don't get the cod
liver taste at alb and the other way
is to 'irrsdiate" the milk itself. All
three methods are used commercially
| and "vitamin d milk" is on the market
like other milk, though 1t costs
little more. Each product Of this
kind IS, of course. subject to inspec-
ton, not only for ordinary wholesome
ness. but to prevent deception by false
labelling.
NT1TAMIN D for adults is not much
of a question. Their bones are
built, and If they get plenty of out
door sunshine the small amounts of
vitamin D they get in the milk, butter,
eggs, salmon. sardines and liver they
eat are probably all they need. nutri-
tionists say. Not sunshine through
windowpanes, however, or through any
other glass. unless it is the kind Of
glass specially manufactured to let
the ultraviolet rays come through.
outdoor sunshine, however, cannot be
improved upon.
For both these vitamins, then
vitamins A and Dive look to certain
foods of animal origin: Eggs, butter
cream, cheese, milk. liver, kidney,
salmon and some other fish, also cod
liver oil. For mitamin A we look also
to green and yellow vegetables and
yellow fruits. For vitamin D we look
to direct sunshine as well as to the
foods already mentioned, to cod liver
oil and to milk enriched with vita
