The fields of dietetics and nutrition are crucial in promoting health and managing disease through food and nutrition programs. While both dietitians and nutritionists work in the health and wellness industry, focusing on the impact of nutrition on the human body, there are key differences in their education, certification, job responsibilities, and, consequently, their salaries. This article explores these distinctions to help you understand which career path might be the right fit for you.
Defining Dietitians and Nutritionists
