The effects of three dietary phosphorus concentrations on magnesium balance in very low birth weight (VLBW) infants were measured. The infants consumed one of three special formulas for 20 consecutive days. Magnesium balance was calculated by measuring food intake, urinary magnesium and fecal magnesium. The highest dietary phosphorus concentration resulted in a higher (P < 0.05) fecal loss of magnesium. Net absorption and net retention of magnesium were lower (P < 0.10) in the high phosphorus group. A modest (33 per cent) increase in dietary phosphorus resulted in a decrease in magnesium absorption in VLBW infants.
测量了三种膳食磷浓度对极低出生体重（VLBW）婴儿镁平衡的影响。婴儿连续20天食用三种特殊配方奶粉中的一种。通过测量食物摄入量、尿镁和粪镁来计算镁平衡。最高的膳食磷浓度导致镁的粪便流失更高（P<0.05）。高磷组镁的净吸收和净保留较低（P<0.10）。膳食磷适度增加（33%）会导致VLBW婴儿镁吸收减少。
