Registered Dietitian Jobs in Ontario, CA

A Registered Dietitian (RD) is a professional who specializes in food and nutrition, focusing on advising individuals and communities on matters of diet, food, and health. They create dietary plans to promote health, prevent diseases, and enable recovery from illnesses. RDs often work in healthcare facilities, schools, private practices, or government institutions. They may conduct research in food science, guide public health policy, or manage food service operations. They should have a strong foundation in biology, chemistry, nutrition, and behavioral sciences to understand the complex interaction between nutrients and human health.

To become a RD, one should typically have an undergraduate degree in food and nutrition, dietetics, or related areas. They should also complete an accredited, supervised internship. After that, passing the Commission on Dietetic Registration (CDR) exam is mandatory to earn the RD credential. Important skills for a RD include strong analytical abilities to interpret scientific studies and apply them to patients' needs, good communication to explain complex nutritional concepts simply, and problem-solving skills to help patients overcome obstacles. Prior to becoming a RD, individuals might work as a dietetic technician, nutritionist, or a health coach to gain practical experience.
