Newfoundland's cod are positively
ashamed of their livers today.
For years they've been puffed up
with the idea that without them and
the precious vitamins they contain
man would be a bow-legged, shifting
dim-eyed creature. that babies couldn't
get through the winter, and all that.
But the liver oil of the swordfish
contains 100 times more of both Vita
Minis A and D than cod liver Oil,
and that of the black sea bass 300
fold more vitamin A and 5O-fold more
vitamin D.
Lack of vitamin A makes men half
blind, and lack of vitamin D causes
rickets. and lack of either of them
lowers the resistance to such infec-
tlous diseases as colds. Recent ex-
periments showing the enormous re-
serves of these indispensable SUBJ
stances in fish were described by re-
search workers Of the Bureau of
Fisheries to the Fisheries Advisory
Council composed of leaders in the
fishing industry from all over the
country. at the Department of Com
merce yesterday.
Tuna Fish Rating High.
The liver of the tuna fish, it was
shown, has 50O-fold more vitamin D
than that of the cod and 3O-fold
more vitamin A. The salmon has
better than seven times more vitamin
A. So even if all the cod went on
sit-down strike and refused to con-
vert sunshine into either of these
vltamins-a process of which they
were supposed to possess the secret a
few years ago-men could keep on
living as we'll as ever.
Compared with animal foods, it was
found that tuna liver Oil has 1000. 900
times the vitamin D content of milk.
and swordfish oil $4,000 times the
vitamin A content of butter and eggs,
which sometimes have been recon-
mended as good sources.
Other analyses were given showing
that fish are fine source of calcium,
magnesium, phosphorus, sulphur iron
copper and iodine, all of which are
essential in the diet.
Milk is the best known source of
calcium, which is necessary for teeth
and bones and, it now is believed pro-
longs life-but crabmeat has l,489
parts in million of it compared with
1900 for milk. Not that the fishery
experts advise feeding babies crab
meat, however.
Grabs also contain more magnesium
than any other well-known food, 500
parts per million. Magnesium, recent
experiments have shown, may be part
ly responsible for mothers loving their
babies.
Phosphorus in Haddock.
For phosphorus, eat haddock, mack
erel, salmon, shrimp or crab. The only
other common food which contains
anywhere near as much is beef. Phos-
phorus is needed for building up the
brain. Oysters lead all other foods
in iron and copper. Crabmeat tops
the list for sulphur.
Members of the Advisory Council
dined sumptuously at the Mayf1ower
last night on an all-fish dinner and
came away stuffed with enough vita
minis and minerals to keep them poppy
for days. The menu included Gala
lilies of smoked salmon. with centers
of boneless and skinless smoked her
ring; smoked Great Lakes whitefish
on toast, sturgeon, picked and pep
pered shrimp, canapes of whitefish
caviar, sliced smoked New York eel
