ABSTRACT
This evaluation of the relationship of vitamin C with cancer will review reports of human studies published since 1987. Occasional reference will be made to those reviews that have considered the vitamin C and cancer literature prior to 1988 (Block and Menkes, 1989; Stähelin et al., 1987, 1989; Ziegler, 1986). The rationale for the 1988 cutoff was that information prior to 1988 on vitamin C and cancer was considered in the following benchmark references: The Surgeon General’s Report on Nutrition and Health (U.S. Department of Health and Human Services, 1988); Diet and Health: Implications for Reducing Chronic Disease Risk (National Research Council, 1989a); Recommended Dietary Allowances, 10th ed., (National Research Council, 1989b), Nutrition and Your Health: Dietary Guidelines for Americans (U.S. Department of Agriculture and U.S. Department of Health and Human Services, 1990), Healthy People 2000: National Health Promotion and Disease Prevention Objectives (U.S. Department of Health and Human Services, 1991).
