10种不正确的牛奶饮法要注意

发布时间：2011-02-28 来源：

其实现在很多人都会注意保养身体，喝牛奶是其中一种方式，但许多人却不会喝牛奶。据专家介绍，有10种喝牛奶的方法不可取：

一、瓶装牛奶放在阳光下晒，可增加维生素D。牛奶在阳光下乳糖会酵化，使牛奶变质。

二、牛奶越浓越好。

三、牛奶必须煮沸。通常，牛奶消毒的温度要求并不高，70℃时用3分钟，60℃时用6分钟即可。如果煮沸，温度达到100℃，牛奶中的乳糖就会出现焦化现象，而焦糖可诱发癌症。

四、牛奶加巧克力。生成“草酸钙”后变成了对人体有害的物质，从而导致缺钙、腹泻、少年儿童发育推迟、毛发干枯、易骨折以及增加尿路结石的发病率等。

五、以炼乳代替牛奶。炼乳太甜，蛋白质和脂肪的浓度比新鲜牛奶下降了一半。炼乳中加入水，那么糖的含量又会偏高。

六、用酸奶喂养婴儿。尤其是患胃肠炎的婴幼儿及早产儿，如果喂食他们酸奶，可能会引起呕吐和坏疽性肠炎。

七、在牛奶中添加橘汁或柠檬汁以增加风味。会使蛋白质变性，从而降低蛋白质的营养价值。

八、在牛奶中添加米汤、稀饭。米汤和稀饭会破坏牛奶中维生素A。如果摄取维生素A不足，会使婴幼儿发育迟缓，体弱多病。

九、牛奶服药一举两得。在服药前后各1―2小时内最好不要喝牛奶。

十、加糖越多越好。一般是每100毫升牛奶加5―8克蔗糖。把糖与牛奶加在一起加热，生成有害物质糖基赖氨酸。这种物质不仅不会被人体吸收，还会危害健康。因此，应先把煮开的牛奶晾到温热(40℃―50℃)时，再放糖。
