    INTRODUCTION
 
The search for chemoprevention agents to reduce the incidence and burden of cancer has become an increasingly important priority for medical researchers during the past two decades. Focusing on single nutrients, multiple dietary constituents, or complete diets has led researchers to a host of promising agents (1). Among these, {beta}-carotene—an antioxidant that is present in many fruits and vegetables—has been the subject of some of the most intensive chemoprevention research on the basis of substantial evidence from epidemiologic studies that this nutrient has potential to reduce the risk of cancer at various sites, including lung and stomach and possibly esophagus, colorectum, breast, prostate, and cervix (2,3). {beta}-carotene is one of the most commonly used dietary supplements and has been heavily marketed to consumers for protection against cancer, cataracts, and heart disease. The U.S. Food and Drug Administration (FDA) designates {beta}-carotene as "Generally . . . [Full Text of this Article]
