Apparently the source of fat in the diet is less important than simple excess, but (ironically?) polyunsaturated fats appear to be more tumorigenic than saturated fats if persons are consuming low-fat diets. The latter, of course, are now widely recommended for weight control and protection from circulatory disease. Numerous additives have already been found to be carcinogenic and have been banned, and more continue to be, but the problem of avoiding carcinogenic additives is exacerbated by the fact that the rate of introduction of new additives outstrips the rate at which existing ones can be tested for safety. Carcinogenic preparation techniques tend to be localized geographically or culturally and associated with increased rates of cancers at specific sites. Similarly, aflatoxinassociated cancers are most common in areas where control of aflatoxin-contaminated foodstuffs is poor. Some dietary factors appear to be cancerprotective. These include dietary fiber, vitamins A, C , and E, selenium, beta-carotenerich vegetables, and cruciferous vegetables (cabbage family). In accordance with these findings, the Interim Dietary Guidelines recommend a reduction in the total fats in the U.S. diet; increased use of fruits, vegetables, and whole grains, especially citrus, cruciferous, and carotene-rich vegetables; decreased use of salted, pickled, and smoked foods, and alcohol and cigarettes; and continued efforts to identify mutagens in foods and to avoid contamination of foods with carcinogens from any source. The text is long but highly readable. This is not only because the authors are organized, write simply, and define their terms, but also because they exhibit a refreshing concern with objectivity and fairness in dealing with conflicting theories or experimental results, and because they are unusually sensitive to nuances of the English language. For example, the writers are to be congratulated for using the term human (not “man”) nearly throughout the text. The exception to this sensitivity-in chapter 16-is serious enough to merit special mention. In this chapter race (inherited) and ethnicity (learned) are confused; if the authors fear the word race, they can appropriately substitute other terms such as extraction, ancestry, or genetic derivation. It is to be hoped that a second edition or printing will correct this error. Anthropologists of several ilks will find much of potential research interest in this book. For example, the cancer-protective diet not only closely matches the improved diet proposed a few years ago in the (controversial!) U.S. Dietary Guidelines and recommendations long made by health-foodists, but is also the sort of diet humans have presumably consumed during most of their evolutionary history. The implication of many studies quoted in the text is that the destructive effects of carcinogens in foodstuffs or diets can be controlled or cancelled by the simultaneous presence of cancer-protective substances. Thus there is material for both the sociohistorian and the evolutionary biologist, as in the comparative analysis of traditional dietaries, or the reconstruction of the health quality of prehistoric diets combined with paleopathological analysis. Medical anthropoligists might find meat (pun) for comparative research in the emically defined cancer-preventive diets of nonorthodox medical systems,, such as macrobiotics or naturopathy. Finally, despite the simplicity of the guidelines, their low risk, and apparent benefit, on past experience it can probably be predicted that they will meet with resistance. The causes of this resistance, too, are researchable, both as psychological and as sociocultural processes. In summary, this book is useful as a source of factual and bibliographic materials, and as a starting point for creative research. As a bonus, it is also well written and highly interesting CLAIREMONODCASSIDY Ofice of Znternational Programs University of Maryland College Park, Maryland BOOKS RECEIVED Barash, DP (1983) Aging: A n Exploration.
