Current Insights into Industrial Trans Fatty Acids Legal Frameworks and Health Challenges in the European Union and Spain

Abstract

The presence of industrial trans-fatty acids (iTFAs) in processed foods poses significant public health concerns, necessitating comprehensive regulatory frameworks. In this study, the current legal landscape governing iTFA in the European Union and Spain is analyzed, with a particular focus on regulatory effectiveness and implementation challenges. The research methodology combines a systematic review of existing regulations, including EU Regulation No. 1169/2011 and Spanish Law 17/2011, with the analysis of the scientific literature on iTFA health impacts. The results reveal significant regulatory gaps, particularly in enforcement mechanisms and iTFA detection methods. Key challenges are also identified in the present study, including inconsistent compliance monitoring, varying analytical methods for iTFA detection, and contradictions between EU and Spanish regulatory frameworks. Additionally, in this work, the need for harmonized approaches to ultra-processed food regulation is emphasized. Further, the conclusion is that despite the current regulations providing a foundation for iTFA control, it is compulsory to enhance the monitoring systems, and clearer regulatory guidelines are necessary. These would contribute valuable insights for policymakers, food industry stakeholders, and public health professionals working towards effective iTFA regulation.
