A lot of people incorrectly use the terms Nutritionist and Dietitian interchangeably. Even if these two specialists are undoubtedly associated, they maintain distinctive features. The most significant difference between nutritionists and dieticians lies in the authorized restrictions that each title carries. Only nutritionists who become registered may legally call themselves as a dietitian or more precisely, RDs or registered dietitians.
Unlike dietitians, the nutritionist is much less secured under the regulation. Nutritionists that don’t intend to make use of the name dietitian or registered dietitian, are free from government regulation. They both should have graduate/post-graduate degree in nutrition and dietetics, or degree in nutrition and home science.
