The scientific investigations in the Center of Excellence for Nutrition and Metabolism include assessment of the dietary intake using questionnaires and analysis of fatty acids status reflecting both their dietary exposure and endogenous metabolism. Validated questionnaires in accordance with the EU Menu methodology are used for estimation of dietary exposure to selected nutrients in the Center. So far, fatty acid compositions have been determined in circulation and tissues in different groups of respondents and in animal models. So, the aim of this workshop is to interactively present methods, advantages and limitations of different methods that are used for estimation of dietary intake of fatty acids. Furthermore, an overview of literature available data about content of fatty acids will be presented, focusing primarily on information of free on-line available food composition databases. The impact of dietary intake of trans fatty acids on health will be emphasized and currently existing data on their content in foodstuffs in Serbia will be shown. Moreover, the legal regulations concerning trans fatty acids that existence in other European countries will be described. The importance of fatty acid profiles determination as a biomarker of dietary intake, which simultaneously reflects changes in the endogenous metabolism will be highlighted. Finally, an overview of the currently available results for the status of fatty acids in different groups of respondents in Sebia population will be presented.
