Preface
Recently， while reading a book on the energy crisis， I found the Chinese
meaning of the word cr/s/s. The ideograms used to compose the word
are a combination of the symbols for danger and opportunity. This
gave me the idea for the thread~hat runs through this reader on nutrition.
In teaching a beginning course on nutrition to liberal arts students， I
have been confronted continuously in my lectures with the crisis of
widely divided viewpoints on the same supposed fact. A problem
existed in compiling a list of articles for the students to read which gave
the opposing viewpoints on each of the topics in question. The articles
were in quite diverse journals， which would make it difficult for
students to find. Thus， I felt that it would be helpful to compile a reader
of not-too-technical articles which would cover some of the controversial
areas in the field of nutrition. A student of mine made it possible since
her husband was a publisher.
The book covers a wide range of topics. It begins with an explanation
of the Recommended Dietary Allowances (RDA)， and a discussion of the
nutritional status of the U. S. population with respect to this RDA
follows. The malnutrition observed in this country has， in fact， led
to a 1974 Senate hearing on nutrition. It has become clear that a
danger exists for members of our population who are malnourished，
but many opportunities exist to eliminate this crisis.
Other danger areas covered include the misuse of vitamins， the
unwarranted prejudice against sugar cereals which possibly is depriving
some children of breakfast， the misconception that organic foods are
better than processed foods， the relation of diet to heart disease， and the
interest in fad diets. In each case， an attempt has been made to select
articles that present the opposing viewpoints and draw conclusions
which would lead to the opportunity of improved health. This
controversy is no better related than in the chapter on heart disease
and cholesterol.
The final articles peer to the future by examining our world status today.
Will there be enough food， do we have enough energy to process it， and
