PREFACE TO SECOND REVISED EDITION

The old order of things is passing. The keynote of to-day's work is
prevention, rather than cure, children are taught to eat correctly
that they may grow into the strong, healthy men and women which are
needed to make any nation great. This instilling of good health habits
must rest upon the nurse, the nutrition worker, the physician and the
home-maker. Close cooeperation is necessary among these workers and a
definite understanding of the way to accomplish the best results, in
this respect, must come from the training of those who are undertaking
this all important work.

The present revision of this text is the outgrowth of several years of
close attention to the progress, changes and adjustments which are
being made daily in this important subject of nutrition. The changes
made in this revised edition are all in the line of constructive
teaching. The material has been reorganized that no time may be lost
in a search for the proper word to illustrate a definite point. The
method of project teaching used in this edition, is not a new one,
although the name may possibly be unfamiliar to some. Every good
teacher recognizes the value of motivation as a means of getting an
idea "across." The revision of this text was undertaken with the idea
of leading the student to think for herself and to put into practice
the scientific facts learned in class room and ward.

The author is indebted to many of her colleagues for the encouragement
and constructive criticism which enabled her to make the changes which
will, it is hoped and believed, materially aid the student nurse in
the study of Dietetics. She also wishes to express her appreciation
for the many helpful suggestions made by her co-workers in this
respect, especially to Misses L. H. Gillett and L. Willson for
valuable criticism and to Miss H. Buquo for assistance in the
preparation of the manuscript.

PREFACE TO FIRST EDITION

No other science has so much to do with the general welfare of mankind
as the study of food and its effects in the human body. When we use
the term "dietetics" as rep
