After organizing two very successful European Nutrition Conferences which attracted much attention, the need for unification of european nutrition societies has risen. At that point, the plan to create a Federation of European Nutrition Societies (FENS) as a firm basis for the European nutritional science community and the European Nutrition Conferences was made.

According to that plan, FENS was founded during the third European Nutrition Conference in Uppsala, Sweden in 1979, and till today represents the platform where the national Nutrition Societies from all over Europe could connect, share and exchange information, knowledge and ideas and promote the importance of nutrition for public health in Europe.

Today, FENS is a non-profit Federation consisting of 26 European Nutrition societies, each representing one country, with the idea of maintaining a permanent link for exchanges between European nutritionists with basic and applied perspectives. The aim is to combine efforts for the development of research and education in Nutrition Sciences and to promote the importance of adequate Nutrition. The main FENS event remained the European Nutrition Conference, arranged every 4 years. The Croatian Association of Nutritionists (CroAN) in 2018 became a full member of FENS and an official Croatian representative.

The Association for Applied Nutrition in Bosnia and Herzegovina was founded to bring together people working in the field of nutrition, promoting the profession and healthy living.

Members of the Association are citizens of Bosnia and Herzegovina as well as foreign citizens who have been granted residence in Bosnia and Herzegovina, and who accept the Statute and program goals and activities of the Association. Members can also be legal entities registered in Bosnia and Herzegovina, which accept the Statute and goals of the Association, and which participate in the work of the Association through their representatives.

The Sociedade Portuguesa de Ciências da Nutrição e Alimentação (SPCNA) is the Portuguese scientific society bringing together professionals and researchers in the fields of nutrition and food sciences. SPCNA promotes scientific knowledge and good practice in nutrition and organises the national SPCNA Congress. SPCNA joins the 10th International Congress of Nutritionists as an official partner.

Společnost pro výživu, the Czech Society for Nutrition, was founded in 1945 and brings together nutrition experts from the Czech Republic. The Society promotes evidence-based nutrition, education and public health and publishes professional information for its members. As a partner of the Congress, the Society shares information about the 10th International Congress of Nutritionists with its members.

The Serbian Nutrition Society brings together nutrition scientists and professionals in Serbia and supports international collaboration within the nutrition community. The Society joins the 10th International Congress of Nutritionists as a partner and shares information about the Congress with its members.
