Zinc (Zn) deficiency in infancy and early childhood is of public health concern in developing countries. This study aimed to longitudinally assess Zn intake of urban South Indian term infants in the first 6 months of life using measures of breast milk (BM) volume and BM Zn concentrations day(-1) mL and, additionally, to study the effect of BM Zn intake on infant length and weight gain. BM intake by the deuterium dilution technique, BM Zn concentration at months 1, 3 and 6, as well as serum Zn level at months 3 and 6 were assessed in 50 mother-infant pairs. BM intake significantly declined from 627 day(-1) mL at month 1 to 608 at month 6 (P< 0.01). BM Zn concentration and intake significantly declined from month 1 to month 6 (P
