Nutritionist are health providers who specializes in the study of nutrition, which includes preventive nutrition, diseases related to nutrient deficiencies, and the science of nutrition. Dietitians can be considered as a nutritionist, but not all nutritionists are dietitians. In fact, nutritionist is not regulated by any professional regulated body or a legally protected term, hence anyone can essentially refer to themselves as nutritionist, whether they are self-taught or possess a graduate degree in nutrition. Nutritionists are often found in hospitals, outpatient clinics, schools, community and public health settings, culinary and food service, scientific research, businesses, in private practice and other health care facilities.
