Nutr."],"abstract":"<jats:p>Digital technologies such as blockchain, Internet of Things (IoT), and artificial intelligence (AI) are increasingly applied in food supply chains (FSCs) to enhance traceability, monitoring, and quality detection. However, whether these technological advancements ultimately contribute to improved nutritional security remains unclear. This scoping review systematically examined the application of digital technologies across food supply chains and assessed their impacts on food safety, food loss reduction, and nutritional outcomes. Following PRISMA guidelines, we searched Web of Science, Scopus, and PubMed for empirical studies published between 2015 and 2025, with supplementary searches conducted in the Cochrane Library and Global Health databases to ensure comprehensive coverage of nutrition-related evidence. Ultimately, 46 studies were included for analysis. Results revealed that blockchain (41.3%), IoT (26.1%), and AI\/machine learning (19.6%) constitute the primary technological approaches, with storage and transportation being the most concentrated application areas (41.3%). Evidence for positive impacts on food safety and loss reduction is substantial, with 89% and 83% of relevant studies reporting favorable outcomes, respectively. However, only 6.5% of included studies directly measured nutrition-related outcomes, representing a critical evidence gap. This asymmetric evidence distribution suggests that while digital technologies demonstrate clear value in improving supply chain efficiency and food safety, the pathway from technological performance to nutritional improvement remains largely unverified. Future research should incorporate nutrition indicators into evaluation frameworks and prioritize studies in low-income countries where food loss and nutritional insecurity are most severe.<\/jats:p>","DOI":"10.3389\/fnut.2026.1796752","type":"journal-article","created":{"date-parts":[[2026,3,31]],"date-time":"2026-03-31T04:11:08Z","timestamp":1774930268000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Digital technologies for sustainable food supply chains: a scoping review of impacts on food safety, loss reduction, and implications for nutritional security"],"prefix":"10.3389","volume":"13","author":[{"given":"Shuang","family":"Li","sequence":"first","affiliation":[{"name":"Department of Economic Management, Beijing Jiaotong University","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoyang","family":"Li","sequence":"additional","affiliation":[{"name":"School of Accounting, Guangzhou College of Technology and Business","place":["Guangzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tianyi","family":"Kong","sequence":"additional","affiliation":[{"name":"Division of the Humanities, University of Chicago","place":["Chicago, IL, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,3,31]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"102008","DOI":"10.1016\/j.ijinfomgt.2019.09.004","article-title":"A blockchain use case in food distribution: do you know where your food has been?","volume":"52","author":"Bumblauskas","year":"2020","journal-title":"Int J Inf Manage."},{"key":"B2","doi-asserted-by":"publisher","first-page":"479","DOI":"10.1016\/j.resconrec.2019.06.011","article-title":"Quantification of food waste per product group along the food supply chain in the European Union: a mass flow analysis","volume":"149","author":"Caldeira","year":"2019","journal-title":"Resour Conserv Recycl."},{"key":"B3","volume-title":"The State of Food Security and Nutrition in the World 2023: Urbanization, Agrifood Systems Transformation and Healthy Diets across the Rural\u2013Urban Continuum","year":"2023"},{"key":"B4","doi-asserted-by":"publisher","first-page":"216","DOI":"10.1504\/IJPQM.2020.105963","article-title":"Integrity of food supply chain: going beyond food safety and food quality","volume":"29","author":"Ling","year":"2020","journal-title":"Int J Product Qual Manag."},{"key":"B5","doi-asserted-by":"publisher","first-page":"101969","DOI":"10.1016\/j.ijinfomgt.2019.05.025","article-title":"Boundary conditions for traceability in food supply chains using blockchain technology","volume":"52","author":"Behnke","year":"2020","journal-title":"Int J Inf Manage."},{"key":"B6","doi-asserted-by":"publisher","first-page":"2046","DOI":"10.3390\/su11072046","article-title":"Identifying factors associated with food losses during transportation: potentials for social purposes","volume":"11","author":"Lipi\u0144ska","year":"2019","journal-title":"Sustainability."},{"key":"B7","doi-asserted-by":"publisher","first-page":"571","DOI":"10.1007\/s12571-021-01238-9","article-title":"Estimation of nutritional postharvest losses along food value chains: a case study of three key food security commodities in sub-Saharan Africa","volume":"14","author":"Bechoff","year":"2022","journal-title":"Food Secur."},{"key":"B8","doi-asserted-by":"crossref","first-page":"235","DOI":"10.1016\/B978-0-12-820521-1.00010-1","article-title":"Chapter 10 -
