The purpose of this study was to determine riboflavin intake and status of Korean adults. Three consecutive 24-h food recalls were collected from 412 (145 men and  267 women) healthy adults, aged 20\u201364 years, living in South Korea and urine samples were collected from 149 subjects of all subjects. The dietary and total (dietary plus supplemental) riboflavin intake was 1.33 \u00b1 0.34 and 2.87 \u00b1 6.29 mg\/day, respectively. Approximately 28% of the subjects consumed total riboflavin less than the Estimated Average Requirement. Urinary riboflavin excretion was 205.1 \u00b1 190.1 \u03bcg\/g creatinine. Total riboflavin intake was significantly positively correlated to the urinary riboflavin excretion. (r = 0.17171, p = 0.0363). About 11% of the Korean adults had urinary riboflavin &lt;27 \u03bcg\/g creatinine indicating a riboflavin deficiency and 21% had low status of riboflavin (27 \u03bcg\/g creatinine \u2264 urinary riboflavin &lt; 80 \u03bcg\/g creatinine). Thus, one-third of Korean adults in this study had inadequate riboflavin status. In some adults in Korea, consumption of riboflavin-rich food sources should be encouraged.<\/jats:p>","DOI":"10.3390\/nu7010253","type":"journal-article","created":{"date-parts":[[2014,12,31]],"date-time":"2014-12-31T08:49:33Z","timestamp":1420015773000},"page":"253-264","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Evaluation of Riboflavin Intakes and Status of 20\u201364-Year-Old Adults in South Korea"],"prefix":"10.3390","volume":"7","author":[{"given":"Ji","family":"Choi","sequence":"first","affiliation":[{"name":"Department of Food & Nutrition, Duksung Women's University, Seoul 132-714, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Young-Nam","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Food & Nutrition, Duksung Women's University, Seoul 132-714, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youn-OK","family":"Cho","sequence":"additional","affiliation":[{"name":"Department of Food & Nutrition, Duksung Women's University, Seoul 132-714, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2014,12,31]]},"reference":[{"key":"ref_1","unstructured":"Ministry of Health and Welfare, and Korea Centers for Disease Control and Prevention (2009).
