Abstract: A 2-volume reference set for nutrition and cancer research scientists, including epidemiologists, clinicians, and experimentalists, summarizes and discusses a wide variety of studies concerning the role of nutrition in the etiology of various types of cancer, highlighting the potential and limitations of epidemiology, clinical, and experimental studies. The first volume addresses the affects of macronutrients in cancer etiology and treatment, covering various specific cancers (gastric; pancreas; large bowel; colon; breast; prostate), including the role of dietary fat, essential fatty acids, prostaglandins, and fiber. The role of dietary fat in cancer risk also is reviewed. The second volume covers the role of micronutrients and nonnutritive dietary factors in several types of cancer (breast; esophagus), including retinoids, selenium, and other factors. Special attention also is given to cancer chemoprevention, fermented milk products as cancer inhibitors, the role of food mutagens and carcinogens, nitrosamines in foods, and the effects of alcohol consumption. The 19 review articles comprising this 2-volume set were prepared by experts in their fields.
