A dietitian is a professional nutritionist—an educated food and specialist who is qualified by training and examination to evaluate people's nutritional health and needs. Most dietitians are registered and are referred to as RDs. To become an RD, a person must earn an undergraduate degree in nutrition, food science, or food management, including courses in several other related subjects (chemistry, anatomy and , management, psychology, etc.); complete a 900-hour ; pass a national exam administered by the Commission on Dietetic Registration (the credentialing arm of the American Dietetic Association), and maintain up-to-date knowledge and registration by participating in required continuing education activities, such as attending workshops, doing research, taking courses, or writing professional papers.
