The dietary vitamin B6 intake of 185 Korean children aged 7-12 years (y), who showed no health problems, in the Seoul area and its sources were estimated using a modified Korean vitamin B6 database. The age and sex of each subject was classified according to the classifications in the Korean Recommended Dietary Allowance (RDA). Dietary vitamin B6 intake and food sources were estimated using the three-day recall method with the help of a trained interviewer. Food portion sizes were estimated by using standard household measures and published average portion sizes. The average daily vitamin B6 intake was 1.69±0.50 mg/d in children aged 7-9 y, 1.86±0.44 mg/d in male children aged 10-12 y and 1.77±0.62 mg/d in female children aged 10-12 y. Less than 5% of the subjects consumed less than the Korean RDA of vitamin B6. The average ratio of vitamin B6 intake to daily protein intake was 0.028±0.006 mg/g in children aged 7-9 y, 0.028±0.004 mg/g in male children aged 10-12 y and 0.029±0.007 mg/g in female children aged 10-12 y. The intake of vitamin B6 was significantly (p<.01) positively correlated to the intake of all other nutrients. Foods from animal and plant sources provided 37% and 73% respectively, of total vitamin B6. Major dietary sources of vitamin B6 in children in the Seoul area were rice, soybean sprouts, pork, beef, cereal, kimchi, milk, onions, and potatoes. As for major dietary sources of vitamin B6 the top 20 foods provided nearly 73-75% of the total vitamin B6 consumed by Korean children.
