It is estimated that between 14% and 40% of patients diagnosed with irritable bowel syndrome also have SIBO, highlighting the importance of accurate diagnosis to enable effective treatment plans. Nutrition and diet therapy play a pivotal role in SIBO management, not only in alleviating symptoms but also in preventing relapses. The objective of this review is to gather updated information on dietary management for SIBO to define the role of the dietitian and determine the most suitable nutritional therapy based on scientific evidence. The review will encompass various strategies, ranging from specific diets to dietary supplements, as well as the potential contribution of dietary treatment to improving SIBO.<\/jats:p>","DOI":"10.3390\/nu17091410","type":"journal-article","created":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T03:43:37Z","timestamp":1745379817000},"page":"1410","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Nutritional Approach to Small Intestinal Bacterial Overgrowth: A Narrative Review"],"prefix":"10.3390","volume":"17","author":[{"given":"Sol","family":"Velasco-Aburto","sequence":"first","affiliation":[{"name":"Department of Medicine, Faculty of Medicine, University Complutense, 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6486-0120","authenticated-orcid":false,"given":"Arancha","family":"Llama-Palacios","sequence":"additional","affiliation":[{"name":"Department of Medicine, Faculty of Medicine, University Complutense, 28040 Madrid, Spain"},{"name":"GINTRAMIS Research Group (Translational Research Group on Microbiota and Health), Faculty of Medicine, University Complutense, 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3269-533X","authenticated-orcid":false,"given":"Mar\u00eda Carmen","family":"S\u00e1nchez","sequence":"additional","affiliation":[{"name":"Department of Medicine, Faculty of Medicine, University Complutense, 28040 Madrid, Spain"},{"name":"GINTRAMIS Research Group (Translational Research Group on Microbiota and Health), Faculty of Medicine, University Complutense, 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda Jos\u00e9","family":"Ciudad","sequence":"additional","affiliation":[{"name":"Department of Medicine, Faculty of Medicine, University Complutense, 28040 Madrid, Spain"},{"name":"GINTRAMIS Research Group (Translational Research Group on Microbiota and Health), Faculty of Medicine, University Complutense, 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0244-5065","authenticated-orcid":false,"given":"Luis","family":"Collado","sequence":"additional","affiliation":[{"name":"Department of Medicine, Faculty of Medicine, University Complutense, 28040 Madrid, Spain"},{"name":"GINTRAMIS Research Group (Translational Research Group on Microbiota and Health), Faculty of Medicine, University Complutense, 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Banaszak, M., Gorna, I., Wozniak, D., Przyslawski, J., and Drzymala-Czyz, S.
