编辑同志: 我的4岁女儿特别爱吃糖羹点心、糖果、罐装食品、饮料、麦圈等加工食品。请问,孩子经常吃这些东西好不好?为什么? 深圳马益良马益良同志: 加工食品的营养价值往往低于纯天然食品,因为食品经过高温处理后,一些维生素等营养素会受到破坏。油炸也是加工食品的一种处理方法。食品经过油炸后,脂肪的含量增高,维生素的含量降低,从而使体内积存的脂肪和胆固醇增加,会造成肥胖病。罐装的食品在加工过程中要加入一定量的添加剂,这些添加剂对儿童的影响很大。由于儿童的发育并未成熟,身体各组织对化学物质的反应及解毒功能较成人低很多,长期食用罐装的食品,可能加重脏器的解毒排泄负担,甚至引起某些化学物质的慢性中毒。加工食品中还含有很多防腐剂,会产生磷摄取过剩的问题。虽说磷是形成骨骼或牙齿不可缺的矿物质,但如果摄取过多,也会破坏钙质的平衡。为了恢复钙和磷的正常比例,只好从其他器官中夺取钙质,如此一来,便会造成骨骼、牙齿的衰弱。另外,清凉饮料中也含很多的磷,如果经常吃这一类食品,则会产
Editor’s Comrade: My 4-year-old daughter especially likes sweets, sweets, canned food, drinks, wheat rings and other processed foods. May I ask, children often eat these things? Why? Shenzhen Ma Yiliang Ma Yiliang: The nutritional value of processed foods are often lower than pure natural foods, because the food after high temperature treatment, some vitamins and other nutrients will be destroyed. Fried is also a processed food processing methods. After frying food, fat content increased, vitamin content decreased, so that the accumulation of body fat and cholesterol increase, can cause obesity. Canned food in the process of adding a certain amount of additives, these additives have a great impact on children. Due to the immature development of children, the body’s response to chemical substances and detoxification are much lower than those of adults. Long-term consumption of canned food may increase the detoxification and excretion burden of organs and may even cause chronic poisoning of certain chemical substances. Processed foods also contain a lot of preservatives, will produce excess phosphorus problems. Although phosphorus is an indispensable mineral for the formation of bones or teeth, excessive intake of calcium can also damage the balance of calcium. In order to restore the normal ratio of calcium to phosphorus, it is necessary to take calcium from other organs, and as a result, bone and tooth weakness will result. In addition, soft drinks also contain a lot of phosphorus, if you often eat this type of food, it will produce
