Nutr."],"abstract":"<jats:p>Vitamin D deficiency is a worldwide public health concern, which can be addressed with voluntary or mandatory food fortification. The aim of this study was to determine if branded food composition databases can be used to investigate voluntary fortification practices. A case study was conducted using two nationally representative cross-sectional datasets of branded foods in Slovenia, collected in 2017 and 2020, and yearly sales data. Using food labeling data we investigated prevalence of fortification and average vitamin D content, while nutrient profiling was used to investigate overall nutritional quality of the foods. In both datasets, the highest prevalence of vitamin D fortification was observed in meal replacements (78% in 2017; 100% in 2020) and in margarine, corresponding to high market share. Other food categories commonly fortified with vitamin D are breakfast cereals (5% in 2017; 6% in 2020), yogurts and their imitates (5% in 2017; 4% in 2020), and baby foods (18% in both years). The highest declared average content of vitamin D was observed in margarine and foods for specific dietary use (7\u20138 \u03bcg\/100g), followed by breakfast cereals (4 \u03bcg\/100g), while the average content in other foods was below 2 \u03bcg\/100g. Only minor differences were observed between 2017 and 2020. Major food-category differences were also observed in comparison of the overall nutritional quality of the fortified foods; higher overall nutritional quality was only observed in fortified margarine. Our study showed that branded food composition databases are extremely useful resources for the investigation and monitoring of fortification practices, particularly if sales data can also be used. In the absence of mandatory or recommended fortification in Slovenia, very few manufacturers decide to add vitamin D, and even when this is the case, such products are commonly niche foods with lower market shares. We observed exceptions in imported foods, which can be subject to fortification policies introduced in other countries.<\/jats:p>","DOI":"10.3389\/fnut.2021.775163","type":"journal-article","created":{"date-parts":[[2022,1,4]],"date-time":"2022-01-04T04:41:35Z","timestamp":1641271295000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":12,"title":["Use of Branded Food Composition Databases for the Exploitation of Food Fortification Practices: A Case Study on Vitamin D in the Slovenian Food Supply"],"prefix":"10.3389","volume":"8","author":[{"given":"Sanja","family":"Kru\u0161i\u010d","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ma\u0161a","family":"Hribar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edvina","family":"Hafner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katja","family":"\u017dmitek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Igor","family":"Pravst","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2022,1,4]]},"reference":[{"key":"B1","first-page":"448","volume-title":"Dietary Reference Intakes for Calcium, Phosphorus, Magnesium, Vitamin D, and Fluoride.","year":"1997"},{"key":"B2","doi-asserted-by":"publisher","first-page":"619","DOI":"10.1093\/ajcn\/60.4.619","volume":"60","author":"Holick","year":"1994","journal-title":"McCollum Award Lecture, 1994: vitamin D\u2014new horizons for the 21st century.
