The first volume of the Slovenian food composition database Food composition database was published in 2006, in both electronic and paper versions. When Slovenia joined the EuroFIR NoE, the Biodiverse foods LanguaL indexing system was adopted. The Optijed nutritional software was developed, and later Autochthonous foods upgraded to the OPEN platform. This platform serves as an electronic database that currently comprises Foods at cultivar level 620 foods, and as the Slovenian node in the EuroFIR virtual information platform. With the assimilation of Dietary and nutritional treatment the data on the compositions of foods of plant origin obtained within the latest project, the Slovenian database provides a good source for food compositional values of consistent and compatible quality.
