Provitamin A carotenoids in plant foods are a source of vitamin A for humans; however, several factors, including species of carotenoids, host status, and effectors of absorption can negatively, positively, or in yet undetermined ways affect the bioavailability of these compounds. Staple foods biofortified with provitamin A carotenoids have shown more efficient bioconversion to retinol than generally observed for vegetables (e. g., 3 - 6 versus 10 - 80 beta-carotene to 1 \u00b5g retinol). Staple foods such as maize, rice, and cassava, are generally more accessible than meat or vegetable sources of retinol or provitamin A carotenoids to poor consumers, who are most likely to suffer micronutrient malnutrition. Interdisciplinary teamwork, including plant breeders, nutritionists, government and local agencies, seed companies, and communities, is needed to avail biofortified crops to needy populations. Key steps include developing, validating the nutritional effects of, providing nutrition education concerning, and promoting the use of biofortified crops. Provitamin A carotenoid biofortification of sweet potato, maize, cassava, and rice are at different stages along this continuum. Close linkages between agriculture, nutrition, and health, are essential in the quest to eradicate hunger among the poor. <\/jats:p>","DOI":"10.1024\/0300-9831\/a000042","type":"journal-article","created":{"date-parts":[[2013,2,2]],"date-time":"2013-02-02T02:22:10Z","timestamp":1359771730000},"page":"336-350","source":"Crossref","is-referenced-by-count":83,"title":["Provitamin A Carotenoid Bioavailability:What Really Matters?"],"prefix":"10.31083","volume":"80","author":[{"given":"Sherry A.","family":"Tanumihardjo","sequence":"first","affiliation":[{"name":"Department of Nutritional Sciences, University of Wisconsin-Madison, WI, USA;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natalia","family":"Palacios","sequence":"additional","affiliation":[{"name":"International Maize and Wheat Improvement Center (CIMMYT), Texcoco, Mexico;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kevin V.","family":"Pixley","sequence":"additional","affiliation":[{"name":"International Maize and Wheat Improvement Center (CIMMYT), Texcoco, Mexico;, and Department of Agronomy University of Wisconsin, Madison, WI, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"16242","container-title":["International Journal for Vitamin and Nutrition Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/econtent.hogrefe.com\/doi\/pdf\/10.1024\/0300-9831\/a000042","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,8,9]],"date-time":"2024-08-09T02:10:44Z","timestamp":1723169444000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.imrpress.com\/journal\/IJVNR\/80\/4-5\/10.1024\/0300-9831\/a000042"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,10,1]]},"references-count":0,"journal-issue":{"issue":"45","published-print":{"date-parts":[[2010,10,1]]}},"alternative-id":["10.1024\/0300-9831\/a000042"],"URL":"https:\/\/doi.org\/10.1024\/0300-9831\/a000042","relation":{},"ISSN":["0300-9831","1664-2821"],"issn-type":[{"value":"0300-9831","type":"print"},{"value":"1664-2821","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,10,1]]}}}
