In Spain, diet and nutrition are fundamental to people’s wellbeing and health. Aware of the importance of a balanced diet tailored to individual needs, more and more people are turning to specialist professionals for advice in this field. However, there is often confusion surrounding the terms ‘nutritionist’ and ‘dietitian’.

Although in everyday language the term ‘nutritionist’ is commonly used, the legal and official title is ‘dietitian-nutritionist ’. In addition, there is the role of the Advanced Diploma in Dietetics, popularly known as a ‘dietitian’, who performs complementary functions.

In this article, we will break down these key differences and answer the most frequently asked questions so that you can clearly understand the roles and responsibilities of each of these professionals in the field of nutrition.

What is a dietitian-nutritionist?

A dietitian-nutritionist is a healthcare professional who holds a university degree in Human Nutrition and Dietetics. This professional is qualified to advise you on all matters relating to diet, both in promoting healthy habits and in treating nutrition-related conditions.

In Spain, dietitians and nutritionists form part of the group of healthcare professionals recognised by Law 44/2003 on the regulation of healthcare professions. This means that, unlike other professions, dietitians and nutritionists play a key role in dietary advice, research, teaching and public health.

Prevention and treatment of diseases: They collaborate in the treatment of conditions such as obesity, diabetes and cardiovascular diseases, amongst others.
Research and teaching: They take part in research projects and in the training of future nutrition professionals.
