Dietitian vs nutritionist
Nutritionist (RD or RDNN) registered nutrition is studying food, nutrition and diet education through a well-known university and a recognized curriculum, then completing a strict intranet and one in a registered examination. Become registered nutrition.
Nutrition (without the title of an RD or RDN) studies itself on nutrition through self-study or formal education but does not meet the needs of using RD or RDN titles. Two terms often vary, but they are not the same.
