Prior studies have raised concerns regarding accuracy in offering nutritional advice. We investigated in November 2023 ChatGPT\u2019s potential as a tool for providing nutritional guidance in relation to different non-communicable diseases (NCDs). First, the dietary advice given by ChatGPT (version 3.5) for various NCDs was compared with guidelines; then, the chatbot\u2019s capacity to manage a complex case with several diseases was investigated. A panel of nutrition experts assessed ChatGPT\u2019s responses. Overall, ChatGPT offered clear advice, with appropriateness of responses ranging from 55.5% (sarcopenia) to 73.3% (NAFLD). Only two recommendations (one for obesity, one for non-alcoholic-fatty-liver disease) contradicted guidelines. A single suggestion for T2DM was found to be \u201cunsupported\u201d, while many recommendations for various NCDs were deemed to be \u201cnot fully matched\u201d to the guidelines despite not directly contradicting them. However, when the chatbot handled overlapping conditions, limitations emerged, resulting in some contradictory or inappropriate advice. In conclusion, although ChatGPT exhibited a reasonable accuracy in providing general dietary advice for NCDs, its efficacy decreased in complex situations necessitating customized strategies; therefore, the chatbot is currently unable to replace a healthcare professional\u2019s consultation.<\/jats:p>","DOI":"10.3390\/nu16040469","type":"journal-article","created":{"date-parts":[[2024,2,6]],"date-time":"2024-02-06T07:50:12Z","timestamp":1707205812000},"page":"469","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":99,"title":["Is ChatGPT an Effective Tool for Providing Dietary Advice?"],"prefix":"10.3390","volume":"16","author":[{"given":"Valentina","family":"Ponzo","sequence":"first","affiliation":[{"name":"Department of Medical Sciences, University of Torino, 10126 Torino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilaria","family":"Goitre","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences, University of Torino, 10126 Torino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enrica","family":"Favaro","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences, University of Torino, 10126 Torino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fabio Dario","family":"Merlo","sequence":"additional","affiliation":[{"name":"Dietetic and Clinical Nutrition Unit, Citt\u00e0 della Salute e della Scienza Hospital of Torino, 10126 Torino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Vittoria","family":"Mancino","sequence":"additional","affiliation":[{"name":"Dietetic and Clinical Nutrition Unit, Citt\u00e0 della Salute e della Scienza Hospital of Torino, 10126 Torino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8798-1224","authenticated-orcid":false,"given":"Sergio","family":"Riso","sequence":"additional","affiliation":[{"name":"Dietetic and Clinical Nutrition Unit, Azienda Ospedaliero-Universitaria Maggiore della Carit\u00e0 of Novara, 28100 Novara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6862-8628","authenticated-orcid":false,"given":"Simona","family":"Bo","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences, University of Torino, 10126 Torino, Italy"},{"name":"Dietetic and Clinical Nutrition Unit, Citt\u00e0 della Salute e della Scienza Hospital of Torino, 10126 Torino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,6]]},"reference":[{"key":"ref_1","unstructured":"(2024, January 25).
