许春娣(上海交通大学医学院附属瑞金医院儿内科)配方奶品中蛋白质、脂肪、钙过多,而碳水化合物不足。当蛋白质,尤其是酪蛋白过高时,孩子难以消化吸收,大便呈碱性、干燥。如果配方奶含钙过多,多余的钙会与蛋白质结合成坚实的粪块,与脂肪结合成皂块,大便中肉眼能见到的白色奶瓣就是皂块。奶中糖量不足时,肠蠕动弱,也会使大便潴留、干燥。 Xu Chundi (Department of Pediatrics, Ruijin Hospital, Shanghai Jiaotong University School of Medicine) There are too many protein, fat and calcium in formula but not carbohydrate. When the protein, especially casein is too high, the child is difficult to digest and absorb, the stool is alkaline, dry. If too much formula milk calcium, excess calcium and protein will be combined into a solid feces, combined with fat soap bar, stool in the naked eye can see the white milk is soap bar. Insufficient milk sugar, intestinal peristalsis weak, but also make stool retention, dry.
