For children 4 to 8 years of age it is 1.2 g (53 mmol)/day (1,757 kcal ÷ 2,150 kcal × 1.5 g/day) after rounding. Chloride is assumed to be adequate in equimolar amounts to sodium; thus the AI for chloride for children 1 to 3 years of age is 1.5 g (42 mmol)/day and for 4 to 8 years of age is 1.9 g (53 mmol)/day.

Evidence Considered in Setting the AI

Data are inadequate to set an estimated average requirement (EAR), which requires an indicator of adequacy evaluated at multiple levels of intake, and an assessment of the level at which approximately half of the individuals in the life stage group would demonstrate inadequacy for that indicator. However, available evidence supports an AI of 1.5 g (65 mmol)/day for apparently healthy adults.

First, a diet that provided an average of approximately 1.5 g
