Sodium intake of infants in the United States
1981
Nichols, Buford L. Jr
Analysis of the sodium intakes of infants, based on 1969, 1972, 1974, and 1977 surveys, reveals that intake levels for infants fed breast milk and baby foods are about one-third the calculated requirement. Babies are able to adapt to a wide range of sodium intakes, up to 9.25 mEg/kg/day without measurable changes in blood pressure or extracellular volume. The sodium intakes of older infants have not been reduced, since most of their sodium comes from adult foods and cow's milk. There is little evidence that blood pressure is correlated between childhood and adulthood; that the present low infant sodium intake is harmful; or that intakes up to 9 mEg/kg/day predispose infants to hypertension.
