"CHEW AND CHOOSE"
The Results of Experiments Conduct
ed at Yale.

Chew and choose" is the key To the
important subject of how to attain
maximum working capacity. accord
ing to the report of Professor Irving
Fisher of Yale University on his in
vestigation into the claims previously
made for the beneficial effects of
thorough mastication of food
Professor Fisher has been conduct
ing a series of experiments and in
vestigations on the subject of diet. the
report of one Of which has Just been
issued.
The object was To find what effects
on diet and endurance would follow
from strict obedience to the taste-in-
stinct. when this instince was given
longer chance To act by prolonged
mastication and attentive tasting.
Nothing was SET before the partici-
pants until it was ordered. and the
dictates of appetite We're followed alb
solutely.
The experiment was divided into two
periods. During the first part of the
first period the men showed little
tendency to change their regular food.
either in amount or in kind. on the
other hand, during the latter part OF
the first period, during which thor
ough masticatiOn and instructive eat
ing were practiced. there was dis
tinct though gradual tendency towards
reduction in the amount of food. in
the quantity of proteid. in the guam
tity of flesh foods. and in the guam
tity Of liquids Of all kinds-water. tea.
coffee, cocoa and even soups. During
he Gannn1 Ia. ;..f,,. sc.
Were told to choose low-proteid foods
when their appetite instincts We're in
doubt. Therefore during this period
the force of suggestion To reduce pro-
ted and flesh foods was added To the
effects OF mastication and obedience
To appetite. During this period the
same effects were noted i'm n still
greater degree. Comparing the diet
at the close of the entire five months
of the experiment with the diet ut its
beginning. it was found that the total
calories had fallen about twenty-five
per cent the proteid about forty per
cent. and the flesh foods over eighty
per cent, or to about one-siXth Of their
original amount. The proteid level at
the end Of the experiment correspond
ed closely with the results of Profess
sor Chittenden's experiments.
The result of the experiment throws
light on the problem of the proper
amount OF food and food constituents
for healthy men eating in a natural
manner.
Gymnasium tests We're made at the
beginning, middle and end of the ex-
pertinent. The tests We're of two
kinds-tests Of strength and tests Of
endurance. 1t was found that the
strength of the men remained about
stationary. while their endurance was
nearly doubled. For instance. one
man who could raise on his toes 1868
times in January. succeeded in doing
it 1850 times in June. Another. who
did knee-bending 374 times in Janu-
airy, did it 4j3 times in June. Anoth-
er who did the leg-raising 30 times in
January, did it 50 times i'm June.
The report of another experiment.
which was with forty nine flesh-eat-
ers and Observation-Disclosures. has previ-
ously been made public. and showed
that those who either abstained from
meat altogether or ate il sparingly
had far greater endurance than those
who ate meat in the ordinary guam
titles
Professor Fisher is still engaged in
his Investigations. and further reports
are to follow. Thus far his reports
corroborate the claims of Professor
Chittenden Of Yale and of Mr. Horace
Fletcher in regard to the effective
ness of thorough mastication of food.
