Position of the American Dietetic Association: The role of dietetics professionals in health promotion and disease prevention

In the United States, the leading determinants of morbidity and mortality are rooted in behavioral choices related to eating habits, exercise, tobacco, alcohol consumption, and stress reduction. Scientific data consistently provide evidence that diet plays an important role in health promotion and disease prevention. Healthy eating habits-coupled with other healthful lifestyle behaviors-have the potential to reduce the risk of chronic disease. Health care typically assumes a curative or treatment role in the United States. However, dietetics professionals are shaping an alternate view of health, which includes developing healthy public policies, creating safe and supportive environments, building communities and coalitions, and reorienting health services to include health promotion as a primary approach to delivering health care. Individual-level approaches, such as counseling and group education, have been employed most often in modifying health behaviors. However, population-level approaches that affect availability of or access to healthy foods, opportunities for physical activity, and other healthy lifestyle determinants also are important. Dietetics professionals have pivotal roles in both individual- and population-level approaches.
