Basic calculations for chemical and biological analyses. Bassey J. S. Efiok. AOAC International, Gaitersburg, Md., USA, 1993. (ISBN 0-935584-51-X) 135 pages, paperback. US$45 (USA, Canada, Mexico), US$55 elsewhere.

This book is neither new nor explicitly nutrition-related, but it is exceedingly convenient and useful for the kind of calculation that every nutrition or food scientist is required to make from time to time. It contains the information necessary for calculating the amount, concentration, and preparation of reagents, buffers, spectroscopy, enzyme assays and activities, and radioactivity. Anyone still concerned in any way with calculations of laboratory data will find this inexpensive paperback invaluable.


Carcinogens and anticarcinogens in the human diet. A comparison of naturally occurring and synthetic substances. National Research Council. National Academy Press, Washington, D.C., 1996 (ISBN 0-30905391-9) 417 pages, paperback. US$44.95.

Plants contain chemicals that have medicinal stimulatory, hallucinatory, and narcotic effects, so it is not surprising that they also contain chemicals that are protective against or contributory to cancer. The US National Research Council committee responsible for this report was charged with examining the occurrence, toxicological data, dosage, mechanisms of action, and potential role of natural and synthetic carcinogens and anticarcinogens in food. Despite their enormous number in the food supply, the great majority of naturally occurring and synthetic chemicals in the diet are present at levels below those at which any significant adverse biological effects are likely. Moreover, a varied and balanced diet contributes significant protection. The committee concluded that natural components in the diet may prove to be of greater concern than synthetic components with respect to cancer risk. Even though human epidemiologic data indicate that diet contributes to a significant portion of cancer, it is extremely difficult to assess human cancer risk from individual natural or synthetic compounds, because the diet is such a complex mixture and interactions among components are largely unknown. The report documents and discusses these conclusions.


Trace elements in human nutrition and health. World Health Organization, Geneva, 1996. (ISBN 92-4-156173-4) 343 pages, paperback. SwF 85/ US$76.60; SwF 59.50 in developing countries.

This book provides authoritative recommendations concerning nutritional requirements and safe ranges of intake for 19 trace elements important to human health, based on a consensus of international experts. It combines the latest scientific knowledge about the consequences of specific dietary intakes with practical advice on how to identify the effects of deficiencies and excesses of trace elements. Recommendations for individual elements are presented in the form of safe ranges of intake for population groups and represent the limits of adequacy and safety for the mean intakes of whole populations. The final chapters provide detailed guidelines for the design and interpretation of research on trace elements for human consumption. These include analytical methodologies, dietary surveys, environmental supplies of trace elements, and the differences between population averages and individual intakes.

This book is essential for every nutrition library; it is unfortunate that it cannot be made available even more cheaply for developing countries. A French edition is in preparation.


Vitamin A and the immune function. Edited by Chris Kjolhede and William R. Beisel. Haworth Medical Press, New York, 1996. (ISBN 1-56024757-6) 156 pages, hardback. US$29.95.

This is the report of a 1993 symposium that dealt broadly with vitamin and immune function from basic biochemistry to applied epidemiology and clinical practice. It includes basic information on the metabolism and mechanisms of action of vitamin A, with special reference to infection and immunity, the effects of vitamin A on B-cell and T-cell function, and the complex relationship of vitamin A status, supplementation, and immunocompetence. A comprehensive historical overview by Dr. Beisel provides valuable background. In addition to its authoritative summary of current knowledge, the book will be useful for the design of future indepth investigations.

Title of interest

Food Habits in Later Life: A Cross Cultural Study
By Mark L. Wahlqvist et al.

This study provides scholars, policy experts, and general readers with solid data and analysis regarding dietary practices of diverse populations of elderly communities in Australia, China, Greece, Japan, the Philippines, and Sweden. The work also brings together crosscultural studies of food and health among elderly in other communities of Asia, Europe, and Central America.

The study makes an important contribution to the great need for descriptive research on the health status, lifestyle, and eating habits of the elderly in developed and developing countries. The study also makes available a mass of data needed to determine to what extent eating habits and lifestyle predict health status in the elderly.
