The purpose of this study was to determine thiamin intakes and status of Korean adults. Three consecutive 24‐hour recalls and urine samples were collected from 149 healthy adults (68 males and 81 females) living in Seoul and metropolitan area, Republic of Korea. The means age of the subjects (mean+/‐SD) was 36.9+/‐11.6 years and there was no significant difference by gender. The mean thiamin intakes were 1.29 mg/day and 0.67 mg/1000 kcal. Thiamin intake of males was significantly higher than that of females ( P =<0.001), but there was no significant difference in the ratio of thiamin to energy intake by gender. The percentage contribution from plant foods in thiamin intakes was 63.1%. The Korean adults consuming less the Korean Estimated Average Requirements for thiamin was 10.7% of total subjects. Average urine thiamin concentration was 51.0+/‐50.5 μg/g creatinine. There was no significant difference in urine thiamin levels by gender. Approximately 35.6% of the subjects were thiamin deficient (urine thiamin <27 μg/g creatinine), and urine thiamin concentrations of 42.3% were 27‐<65 μg/g creatinine, which is representative of low riboflavin status. Therefore, some of these Korean adults were at risk of inadequate thiamin status. Korean adults may need to be encouraged to consume thiamin‐rich foods.
