Dietary management for PD patients is a promising adjuvant therapy that may improve some motor and non-motor symptoms. However, there is limited information regarding nutrient intake and adherence to recommended dietary requirements in this population in Lithuania. Methods: In this case\u2013control study conducted at Vilnius University Hospital Santaros Klinikos (2023\u20132025), usual dietary intake was assessed using two non-consecutive 24 h recalls. Intake was compared with Lithuanian Recommended Daily Intake (RDI) values. Associations between nutrient intake and selected non-motor symptoms were analyzed. Results: Fifty-nine patients with PD and 54 controls were included and compared with RDI; patients with PD had lower intakes of dietary fiber (20.63 g\/day), vitamin A (627.15 \u03bcgRE\/day), and vitamin D (3.18 \u03bcg\/day), alongside a higher energy contribution from total sugars (11.31 E%). Less than half met RDI for protein, fat, polyunsaturated fatty acids (PUFA), and monounsaturated fatty acids (MUFA) energy contribution, vitamins E and C, calcium, and zinc. Compared with controls, PD patients consumed more dietary fiber, plant protein, and total carbohydrate and had a higher carbohydrate-derived energy contribution. PD patients with depressive mood consumed fewer carbohydrate, dietary fiber, plant protein, and some vitamins and minerals compared to those without. Conclusions: Patients with PD had higher total sugar-derived energy consumption and lower dietary fiber and vitamin D intake than the RDI. There were differences in dietary intake among PD patients with and without specific non-motor functions.<\/jats:p>","DOI":"10.3390\/nu18081302","type":"journal-article","created":{"date-parts":[[2026,4,20]],"date-time":"2026-04-20T14:53:23Z","timestamp":1776696803000},"page":"1302","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Dietary Intake of Patients with Parkinson\u2019s Disease in Lithuania"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-7778-0884","authenticated-orcid":false,"given":"Jevgenija","family":"Guk","sequence":"first","affiliation":[{"name":"Clinic of Neurology and Neurosurgery, Institute of Clinical Medicine, Faculty of Medicine, Vilnius University, LT-03101 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7850-0510","authenticated-orcid":false,"given":"R\u016bta","family":"Kaladyt\u0117 Lokominien\u0117","sequence":"additional","affiliation":[{"name":"Clinic of Neurology and Neurosurgery, Institute of Clinical Medicine, Faculty of Medicine, Vilnius University, LT-03101 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2013-5618","authenticated-orcid":false,"given":"Anatolij","family":"Ne\u010diporenko","sequence":"additional","affiliation":[{"name":"Clinic of Neurology and Neurosurgery, Institute of Clinical Medicine, Faculty of Medicine, Vilnius University, LT-03101 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1690-6213","authenticated-orcid":false,"given":"Roma","family":"Bartkevi\u010di\u016bt\u0117","sequence":"additional","affiliation":[{"name":"Department of Public Health, Institute of Health Science, Faculty of Medicine, Vilnius University, LT-03101 Vilnius, Lithuania"},{"name":"Public Health Innovation Center, Institute of Hygiene, LT-08107 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4562-1316","authenticated-orcid":false,"given":"Albertas","family":"Barzda","sequence":"additional","affiliation":[{"name":"Public Health Innovation Center, Institute of Hygiene, LT-08107 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6159-4795","authenticated-orcid":false,"given":"Dalius","family":"Jatu\u017eis","sequence":"additional","affiliation":[{"name":"Clinic of Neurology and Neurosurgery, Institute of Clinical Medicine, Faculty of Medicine, Vilnius University, LT-03101 Vilnius, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"901","DOI":"10.1007\/s00702-017-1686-y","article-title":"Epidemiology of Parkinson\u2019s disease","volume":"124","author":"Tysnes","year":"2017","journal-title":"J.
