This literature review aims to summarize and critically evaluate the available evidence on the impact of different dietary patterns and nutrients on the efficacy of FMT. Methods: The present literature review focuses on the impact of diet on the gut microbiota in the context of the effectiveness of fecal microbiota transplantation. A literature review was conducted based on the PubMed Database. Results: More and more data confirm the close link between diet and gut microbiota and suggest that proper nutrition before and after FMT may support the effectiveness of this procedure. It appears that increased fiber intake significantly delays the loss of diversity in the transplanted microbiota, thereby enhancing the beneficial clinical effects following FMT. Additionally, the use of an anti-inflammatory components in the diet combination with FMT could be effective in achieving clinical remission in patients with ulcerative colitis. Conclusions: Based on the literature review, it appears that the most optimal nutritional model (through its beneficial effect on the composition of the gut microbiota, short-chain fatty acids production, and intestinal barrier integrity) to support the effectiveness of FMT is an anti-inflammatory diet rich in dietary fiber (for both the donor and the recipient).<\/jats:p>","DOI":"10.3390\/nu17203314","type":"journal-article","created":{"date-parts":[[2025,10,21]],"date-time":"2025-10-21T15:36:31Z","timestamp":1761060991000},"page":"3314","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["The Impact of Diet on the Fecal Microbiota Transplantation Success in Patients with Gastrointestinal Diseases\u2014A Literature Review"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4318-1513","authenticated-orcid":false,"given":"Natalia","family":"Komorniak","sequence":"first","affiliation":[{"name":"Department of Human Nutrition and Metabolomics, Pomeranian Medical University in Szczecin, 71-460 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1557-6796","authenticated-orcid":false,"given":"Katarzyna","family":"Gawe\u0142","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Pomeranian Medical University in Szczecin, 71-460 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6809-5243","authenticated-orcid":false,"given":"Anna","family":"Deskur","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Pomeranian Medical University in Szczecin, 71-460 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0671-2482","authenticated-orcid":false,"given":"Jan","family":"Pawlus","sequence":"additional","affiliation":[{"name":"Department of General Mini-Invasive and Gastroenterological Surgery, Pomeranian Medical University in Szczecin, 71-460 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4009-1977","authenticated-orcid":false,"given":"Ewa","family":"Stachowska","sequence":"additional","affiliation":[{"name":"Department of Human Nutrition and Metabolomics, Pomeranian Medical University in Szczecin, 71-460 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"151","DOI":"10.1055\/s-0043-1760865","article-title":"Fecal Microbiota Transplantation","volume":"36","author":"Cheng","year":"2023","journal-title":"Clin.
