A dietitian can be defined as a scientific professional of food and nutrition consumed by people across all age levels and health stages. There is need to differentiate a Nutrionist from a Dietitian. One does not need any standardized requirements or qualifications to become a Nutrionist while the Registered Dietitian must be accredited after pursuing specific academic courses and completed a dietetic internship in practical field.
Dietitian has different lines of fields where he or she can work. The most common fields for Dietetics include Food service, clinical, and community. The food service field includes working in restaurants, schools, and as food distributors. In clinical field, dietitians work in medical institutions such as clinics and hospitals attending outpatients and inpatients, or even long-term patient care. Moreover, dietitians can work in health maintenance organizations such as healthcare facilities. In community nutrition, the dietitians help the public on their health in providing services such as nutrition coordination, consultations, as well as research and development. Sport nutrition is noted to be a fast growing Dietetics field.
Furthermore, Dietetics has been found to be the fastest growing career globally despite of being a new field of study. The statistics show that the employed Dietitians in 2008 were 60,300 but Bureau of Labor Statistics predicted that the number should be increased by 9 percent in 2018.  The Dietitians average annual income in the U.S. was around $5,000 but their salaries increase with the level of field experiences but not the increase of academic knowledge.
As such, the Dietetics career growth is based on emphasis that focus on disease prevention through healthy living and lifestyle habits. The quote “prevention is the best cure” is a motto for the dietitians. It means dietitians have the mandate to prevent diseases in the community to avoid future costs for visiting doctors and physicians to treat them for late diagnosis.
