Abstract:
Objective To analyze the energy supply nutrients (protein,fat and lactose) and mineral elements (calcium,copper,iron,zinc,magnesium,sodium,potassium) supplied in breast milk from the resident of Lanzhou,and investigate the problems of those energy supply nutrients and mineral elements in breast milk of this population so that to provide basis for breast feeding.Methods Breast milk from 1 215 mothers whose babies were fed totally by the breast milk and grew well was collected and assayed for the contents of protein,fat,lactose,calcium,copper,iron,zinc,magnesium,sodium and potassium in Lanzhou region.The optimal range for breast feeding was set by normal distribution method.The results were compared with the breast milk from other internal region in order to clarify the contents difference.Results The prevalence of mother-milk-fed in this region was 48.5％.The normal ranges (unit:g/100 g) of fat,lactose and protein were 1.57-5.11,6.58-7.16 and 0.79-1.35,and the normal ranges of calcium,copper,iron,zinc,magnesium,sodium and potassium were 5.25-7.83 mmol/L,5.66-8.28 mmol/L,0.14-0.3 mmol/L,15-64.48 μmol/L,0.98-1.62 mmol/L,1.92-18.82 mmol/L,7.95～ 17.31 mmol/L in the high quality breast milk.Compared with the other internal region,the normal ranges of the protein,fat and lactose in Lanzhou were lower.The contents of protein,fat,lactose,calories,calcium,copper,zinc and sodium in the breast milk from the whole investigated population were significantly lower compared with breast milk of high quality (P＜0.01).Conclusion The quality of breast milk in Lanzhou is not so good.The contents of various nutrients in breast milk should be improved to a proper level by appropriate ways so that to improve the growth and development of the baby.
