girls and young women. The AI for chloride is set at a level equimolar to sodium.
Sodium and Chloride AI Summary, Pregnancy
AI for Sodium for Pregnancy
14–18 years
1.5 g (65 mmol)/day of sodium
19–30 years
1.5 g (65 mmol)/day of sodium
31–50 years
1.5 g (65 mmol)/day of sodium
AI for Chloride for Pregnancy
14–18 years
2.3 g (65 mmol)/day of chloride
19–30 years
2.3 g (65 mmol)/day of chloride
31–50 years
2.3 g (65 mmol)/day of chloride
Lactation
Evidence Considered in Setting the AI
A small amount of sodium is secreted daily in human milk during the first 6 months of lactation (0.12 g [5.2 mmol]/day) (see earlier section, “Infants Ages 0 Through 12 Months”). There is no evidence to suggest that the sodium requirements of lactating women differ from that of nonlactating women. The estimated median energy intake of lactating women (2,066 kcal/day [IOM, 2002]) falls within the range of energy consumed by young men and women (IOM, 2002). Therefore, the AI for sodium for lactating women is set to be equal to that of nonlactating women. The AI for chloride is set at an equimolar amount based on the AI for sodium.
