Definition
Plural of dietitian; multiple healthcare professionals trained and certified in nutrition science who treat diseases and promote health through diet.
Etymology
From 'diet' (food regimen) + '-itian' (a variant suffix for specialist practitioners), pluralized with '-s'. The 'dietitian' spelling became preferred over 'dietician' in formal professional use.
Kelly Says
Interestingly, the Academy of Nutrition and Dietetics—the credentialing body—uses 'registered dietitian' (RD) or 'registered dietitian nutritionist' (RDN), showing how the profession continually updates its title to better reflect its evolving scientific role.

Gender History
Dietitian credentials (RD/RDN) emerged in the 20th century as the profession professionalized; despite requiring advanced education, the field remains 95%+ women, reflecting gender segregation in healthcare.
Inclusive Usage
Use 'registered dietitian (RD)' or 'registered dietitian nutritionist (RDN)' with credential notation; avoid assumptions that all practitioners are women.
Inclusive Alternatives
["registered dietitian","registered dietitian nutritionist","clinical nutrition specialist"]
Empowerment Note
Women registered dietitians established evidence standards for medical nutrition therapy and continue advancing the science despite gender-based wage and recognition gaps in healthcare.
