小儿生长发青旺盛时期,每日需钙600～800毫克,若喂养不当,极易出现缺钙,导致骨骼、牙齿发育畸形,手足抽搐,引起佝偻病。预防小儿佝偻病,除增加含钙食物的摄入外,补钙的同时,还应注意影响钙吸收的因素: ①食物的酸碱度:钙易溶于酸性溶液,而在碱性环境则会形成难溶性钙盐,因此,多吃酸性水果、果汁、乳酸、氨基酸等,能促进钙的吸收。②食物中某些成份:菠菜、竹笋等富含草酸,草酸能与钙结合为不溶性的草酸钙,使钙的利用率下降,因此这类食物少吃为佳。
Growth and development of children during the strong blue, 600-800 mg daily calcium, if improper feeding, prone to calcium deficiency, leading to skeletal, dental deformities, hand-foot convulsions, causing rickets. Prevention of pediatric rickets, in addition to increasing the intake of calcium-containing foods, while calcium, but also pay attention to factors that affect calcium absorption: ① food pH: calcium soluble in acidic solution, and in the alkaline environment will form insoluble Calcium salt, therefore, eat more acidic fruits, juices, lactic acid, amino acids, etc., can promote the absorption of calcium. ② some of the ingredients in food: spinach, bamboo shoots and other rich in oxalic acid, oxalic acid and calcium combined into insoluble calcium oxalate, calcium utilization decreased, so eat less food better.
