Registered Dietitian Nutritionist Day – March 12

The story of dietetics dates back much further, even before the establishment of Registered Dietitian Nutritionist Day. The profession has a rich history, and over the years, dietitians have evolved from a relatively small group of nutrition experts to highly regarded healthcare professionals.

The field of dietetics began to take shape in the late 19th century as the importance of nutrition in the treatment of diseases became evident. The earliest recognized dietitians worked in hospitals, assisting physicians with creating specialized diets for patients. These early dietitians were primarily women, and the profession began to develop as a formalized field of study.

The pivotal moment for dietetics came in 1917 when the American Dietetic Association (ADA) – the precursor to the Academy of Nutrition and Dietetics – was formed. The ADA’s creation marked the beginning of a more standardized approach to dietetics, and it aimed to set professional guidelines, create educational programs, and provide accreditation for those wishing to become dietitians.

In the following decades, the role of dietitians expanded beyond hospitals to include public health nutrition, food service management, and community outreach. By the mid-20th century, the field had grown so much that it became necessary to establish more formal processes for certifying dietitians, including education and professional qualifications.

By the early 21st century, the profession of dietetics had gained widespread recognition as an essential part of healthcare. To help elevate the status of dietitians and nutritionists and further educate the public about the importance of good nutrition, the Academy of Nutrition and Dietetics decided to establish Registered Dietitian Nutritionist Day in 2008.

This day was chosen to coincide with National Nutrition Month, which takes place every March. National Nutrition Month is a campaign designed to encourage individuals to learn about the role nutrition plays in their overall health and well-being. By highlighting Registered Dietitian Nutritionist Day, the AND hoped to bring more attention to the important work RDNs do every day, whether it's helping individuals manage chronic diseases, offering personalized nutrition advice, or promoting public health through community outreach.

Since then, March 12 has become a day to celebrate and honor the contributions of dietitians who are committed to improving lives through nutrition. It is a time to raise awareness about the expertise that dietitians bring to the healthcare system and to encourage the public to seek out their guidance to achieve better health.
