Nutrition is well-recognized as a necessary component of educational programs for physicians. This is to be valued in that of all factors affecting health in the United States, none is more important than nutrition. This can be argued from various perspectives, including health promotion, disease prevention, and therapeutic management. In all cases, serious consideration of nutrition related issues in the practice is seen to be one means to achieve cost-effective medical care. These modules were developed to provide more practical knowledge for health care providers, and in particular primary care physicians. This module is designed to help primary care physicians become critical reviewers of nutritional information. These skills will help the physician to be able to critique nutritional claims and teach patients how to assess fad diets and popular nutritional products. Included are learning goals and objectives, a self-check of achievement with regard to goals, and references for the physician and for the physician to recommend to patients. Appendices include patient handouts concerning avoidance of nutritional quackery, and the dangers of herbal teas. (CW)
