Abstract
Data have been presented from 934 nutrition histories on 63 children in the first 5 years of life. Thiamine, riboflavin and niacin intakes have been computed in terms of quartiles and maximum and minimum levels observed. Some individual patterns of intake are shown. The intake of thiamine rises steadily during the first 15 months, then reaches a plateau which is maintained until just after three years, after which it increases again. The median of these data is slightly above the National Research Council Recommended Allowance. The riboflavin intake, after an initial rise in the first year, decreases in the second and third years with a decrease in milk consumption, then rises again between three and 5 years. More than 75% of the children in this group consume an amount of riboflavin greater than the Recommended Allowance throughout this age period. The niacin intake tends to increase throughout this age span, although the children with high intakes during the second year are likely to show a decrease during the third year. Although only 25% of the children meet the Recommended Allowance, there is no evidence that their intake is inadequate, as judged by growth rate and absence of deficiency symptoms.
