- Approach and Resources for the Sustainable Update of the Portuguese Food Composition Database: A Multi-Source and Collaborative StrategyPublication . Dias, Maria da GraçaBackground and Objectives: The National Institute of Health Doutor Ricardo Jorge (INSA) compiles the Portuguese Food Composition Database (FCDB). Since the first edition in 1961, formats, components, data sources, and management have evolved. Participation in the EuroFIR Network (2005–2010) helped INSA establish strategies, collaborative networks, and infrastructures to ensure regular updates and long-term sustainability. The 2023 version (6.0) includes 44 components for 1330 generic foods, with a new release planned for early 2025. This study presents the strategy and resources for updating the FCDB, integrating analytical and other data sources, while highlighting the role of stakeholders and digital tools in the process. Methods: To ensure data accuracy, INSA conducts an annual analytical program, analysing 12–22 food pool samples in its accredited laboratories. This program prioritizes key foods and components, under the Analytical Updating Commission (AUC). For the 2025 update, Total Diet Study (TDS) nutrient samples were evaluated for adequacy to generic food profiles. Additional analytical data from the industry and distribution sectors were collected via PortFIR’s working group (GTTCA), while addressing user needs. Additionally, European food composition resources (e.g., FoodExplorer-EuroFIR) and food labelling data were used to enhance data completeness. FoodCASE® ensures compliance with EuroFIR’s technical requirements, with automated checks detecting inconsistencies, which are then manually reviewed and corrected. Results: The 2025 FCDB update includes new foods and components, along with nutrient revisions (mainly salt and sugar) linked to the national reformulation strategy. The annual analytical program, based on AUC prioritization, provides high-quality nutrient data, improving dietary representativeness. Regarding TDS-based analytical data, 164 TDS samples were analysed, with nearly 58% integrated into the FCDB, based on composition suitability. The GTTCA, which meets bimonthly, includes 74 members, representing data users and producers, playing a key role in revising the FCDB, ensuring national data access, and addressing user needs. The PortFIR® website remains a key dissemination platform, providing free access to the FCDB, along with tools for food comparisons, recipe calculations, and dataset downloads. Conclusions: A multi-source, collaborative approach is key to ensuring sustainable FCDB updates. However, financial constraints remain a major challenge, as the Ministry of Health lacks dedicated funding for analytical programs. Additional resources and institutional support are essential to guarantee the long-term sustainability of the FCDB, supporting nutrition research, public health, and the food industry.
- From health impact to green choices: The dual impact of fermented foodsPublication . Assunção, Ricardo; Laranjo, MartaFermented foods (FF) have been an essential part of human diets across cultures, cherished for their distinctive flavors and preservation capabilities. Beyond their culinary value, FF have shown significant potential health benefits (1). Studies link fermented foods to antioxidation, lower blood lipid levels, enhanced immunity, tumor inhibition, delayed aging, and prevention of gastrointestinal disorders (2). However, their consumption needs caution regarding potential risks, such as pathogenic contamination or the formation of harmful by-products during fermentation. The safety of fermented foods is currently being systematically revised within the PIMENTO CA20128 under WG3-Health benefits and risks of fermented foods. To navigate these complexities, risk-benefit assessment methodologies provide a robust scientific framework to evaluate the trade-offs, enabling evidence-based dietary recommendations (3). Sustainability is another pivotal aspect of fermented foods. In the face of global challenges like food waste and climate change, fermentation emerges as a key strategy (4). For instance, kimchi and sauerkraut help preserve surplus vegetables, while yogurt and kefir optimize dairy utilization. Nonetheless, the production of certain products, such as fermented meats, underscores the need for strategies to mitigate their environmental impacts while maintaining their benefits. This communication highlights the dual role of fermented foods in promoting health and enhancing sustainability. By bridging tradition and innovation, fermented foods hold the potential to support the transition towards sustainable food systems, paving the way for future diets that address pressing public health and environmental priorities.
- Tracking Mycotoxin Exposure in Portugal: New Insights and Key DeterminantsPublication . Namorado, Sónia; Maris, Elias; Chen, A.; Pero-Gascon, Roger; de Boevre, Marthe; De Saeger, Sarah; Silva, Maria João; Alvito, Paula; .Human biomonitoring (HBM) is a vital tool for assessing exposure to environmental chemicals. Mycotoxins have been associated with various adverse health effects, including estrogenic, immunotoxic, nephrotoxic, and teratogenic outcomes. In this presentation an overview of two recent HBM studies on multiple mycotoxins exposure biomarkers conducted in Portugal will be given. The first study analyzed 37 mycotoxin biomarkers in urine samples from 94 adult participants (48.4 ± 15.2 years), as part of the National Food, Nutrition, and Physical Activity Survey (2015–2016). Six different mycotoxins -DON, ZEN, AOH, OTA, FB1, and CIT- was confirmed through the quantification of 12 urinary biomarkers in paired 24 h and first-morning urine samples. DON and its metabolites were among the most frequently detected biomarkers and AOH was identified for the first time in urine samples from a European population. Associations between urinary mycotoxin biomarkers and consumption of specific food items were also observed. More recently, a subset of 295 first-morning urine samples from adults (28–39 years) was collected between 2019-2020, as part of a cross-sectional study embedded within the Portuguese National Health Examination Survey (INSEF). These samples were analyzed using a newly optimized and validated LC-MS/MS method capable of detecting 40 mycotoxins and/or their metabolites in urine. DON and tenuazonic acid were the most frequently detected, with detection rates of 85% and 96%, respectively. Further investigations into key exposure determinants—including dietary habits, demographic factors, and geographical variations—are ongoing and will be presented. Altogether, these findings highlight the importance of continued surveillance and the integration of HBM into national food safety and public health strategies.
