Dietitian

They supervise the preparation and service of food, develop modified diets, participate in research, and educate individuals and groups on good nutritional habits. The goals of dietitians are to provide medical nutritional intervention, and to obtain, safely prepare, serve and advise on flavorsome, attractive, and nutritious food for patients, groups and communities. Dietary modification to address medical issues involving dietary intake is a major part of dietetics (the study of nutrition as it relates to health). For example, working in consultation with physicians and other health care providers, a dietitian may provide specific artificial nutritional needs to patients unable to consume food normally. Professional dietitians may also provide specialist services such as in diabetes, obesity, oncology, osteoporosis, paediatrics, renal disease, and micronutrient research.

Different professional terms are used in different countries and employment settings, for example, clinical dietitian, community dietitian, dietetic educator, foodservice dietitian, registered dietitian, public health dietitian, therapeutic dietitian, or research dietitian. In many countries, only people who have specified educational credentials and other professional requirements can call themselves "dietitians" — the title is legally protected. The term "nutritionist" is also widely used; however, the terms "dietitian" and "nutritionist" should not be considered interchangeable — the training, regulation and scope of practice of the two professional titles can be very different across individuals and jurisdictions.

In many countries, the majority of dietitians are clinical or therapeutic dietitians, such as the case of the United States, the United Kingdom, and much of Africa. In other countries they are mostly foodservice dietitians, such as in Japan and many European countries.
