The current study aimed to assess the current pricing status of GFPs in the Greek retail market, with a focus on differences between staple and non\u2010staple foods. The retail price and packaging weight of all available GFPs and their gluten\u2010containing (GCPs) counterparts of a GFP\u2010shopping basket (formulated based on the results of a preceding online survey) were recorded by visiting one store of the five most popular reported supermarket chains. The food categories were grouped into staple (e.g. breads, pasta and flours) and non\u2010staple (e.g. chips, sweets and sauces) foods. Adjusting for supermarket chain and product type, a quantile mixed regression model was applied to assess the extent to which median product price (per 100\u2009g) differed between GFPs and GCPs. The unique products recorded were 1058 (of which 408 GFPs), with a total of 2165 retail price recordings. While the overall median price\/100\u2009g of GFPs was not found to be significantly different from that of GCPs, the median price of staple GFPs was estimated to be higher than staple GCPs (+\u20ac1.03 [95% CI: \u20ac0.93; \u20ac1.13] per 100\u2009g), whilst that of non\u2010staple GFPs was slightly lower (\u2212\u20ac0.20 [95% CI: \u2212\u20ac0.37; \u2212\u20ac0.02] per 100\u2009g). In conclusion, the persisting higher cost of staple GFPs suggests the need for ongoing financial support for people with coeliac disease.<\/jats:p>","DOI":"10.1111\/nbu.12716","type":"journal-article","created":{"date-parts":[[2024,10,26]],"date-time":"2024-10-26T07:54:03Z","timestamp":1729929243000},"page":"44-51","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Higher cost of gluten\u2010free products compared to gluten\u2010containing equivalents is mainly attributed to staple foods"],"prefix":"10.1111","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1344-2505","authenticated-orcid":false,"given":"Eirini","family":"Bathrellou","sequence":"first","affiliation":[{"name":"Department of Nutrition and Dietetics, School of Health Sciences and Education Harokopio University of Athens  Athens Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vasiliki","family":"Bountziouka","sequence":"additional","affiliation":[{"name":"Computer Simulations, Genomics and Data Analysis Lab, Department of Food Science and Nutrition University of the Aegean  Lemnos Greece"},{"name":"Policy and Practice Research and Teaching Department GOS Institute of Child Health, UCL  London UK"},{"name":"Department of Cardiovascular Science University of Leicester  Leicester UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Despoina","family":"Lamprou","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Dietetics, School of Health Sciences and Education Harokopio University of Athens  Athens Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Evanthia","family":"Fragedaki","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Dietetics, School of Health Sciences and Education Harokopio University of Athens  Athens Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eleftheria","family":"Papachristou","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Dietetics, School of Health Sciences and Education Harokopio University of Athens  Athens Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank","family":"Vriesekoop","sequence":"additional","affiliation":[{"name":"Department of Food, Land and Agribusiness Management Harper Adams University  Newport UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meropi D.","family":"Kontogianni","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Dietetics, School of Health Sciences and Education Harokopio University of Athens  Athens Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,10,26]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/jhn.12754"},{"key":"e_1_2_11_3_1","first-page":"287","article-title":"Perceived barriers to gluten\u2010free diet adherence by people with celiac disease in Greece","volume":"36","author":"Bathrellou E.","year":"2023","journal-title":"Annals of Gastroenterology"},{"key":"e_1_2_11_4_1","first-page":"172","article-title":"The economic iceberg of celiac disease: more than the cost of gluten\u2010free food","volume":"167","author":"Bozorg S.R.","year":"2024","journal-title":"Gastroenterology"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ehb.2018.06.001"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/pubmed\/fdz034"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1039\/D0FO02630A"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1080\/10408398.2020.1823814"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.3109\/09637486.2013.879286"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijgfs.2017.01.001"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1038\/ejcn.2016.139"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.15557\/PiMR.2015.0039"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/jhn.12502"},{"key":"e_1_2_11_14_1","doi-asserted-by":"publisher","DOI":"10.18637\/jss.v057.i13"},{"key":"e_1_2_11_15_1","unstructured":"Greek Government Gazette.
