This article describes the process of enacting this mandatory regulation, pioneering in Europe, from initial parliamentary discussions in 2012 to the first formal impact evaluation in 2024. Portugal faced significant technical and political challenges, including industry lobby, defining \u201cunhealthy\u201d foods and monitoring and enforcing the law. Despite its limitations, the law stands as a successful example that can support other countries in developing similar regulatory frameworks. Portugal\u2019s experience illustrates the importance of political will and multisectoral collaboration in successfully implementing such restrictions. Further recommendations include clear nutrient profiling, strong monitoring and enforcement mechanisms and maintaining dialogue while anticipating potential opposition.<\/jats:p>","DOI":"10.3389\/fpos.2025.1702075","type":"journal-article","created":{"date-parts":[[2026,1,9]],"date-time":"2026-01-09T06:40:13Z","timestamp":1767940813000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Implementing a law restricting unhealthy food advertising in Portugal: a 13-year journey"],"prefix":"10.3389","volume":"7","author":[{"given":"Marta","family":"Figueira","sequence":"first","affiliation":[]},{"given":"Pedro","family":"Gra\u00e7a","sequence":"additional","affiliation":[]},{"given":"Magdalena","family":"Muc","sequence":"additional","affiliation":[]},{"given":"Maria Jo\u00e3o","family":"Greg\u00f3rio","sequence":"additional","affiliation":[]}],"member":"1965","published-online":{"date-parts":[[2026,1,9]]},"reference":[{"key":"ref1","year":"2012"},{"key":"ref2","year":"2016"},{"key":"ref3","year":"2019"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"e221037","DOI":"10.1001\/jamapediatrics.2022.1037","article-title":"Association of food and nonalcoholic beverage marketing with children and adolescents' eating behaviors and health: a systematic review and meta-analysis","volume":"176","author":"Boyland","year":"","journal-title":"JAMA Pediatr."},{"key":"ref5","doi-asserted-by":"publisher","first-page":"e13447","DOI":"10.1111\/obr.13447","article-title":"Systematic review of the effect of policies to restrict the marketing of foods and non-alcoholic beverages to which children are exposed","volume":"23","author":"Boyland","year":"","journal-title":"Obes.
