饮食误区

    ①烧好的菜不马上吃：有人为节省时间，喜欢提前把菜烧好，然后在锅里温着等人来齐再吃或下顿热着吃．其实蔬菜中的维生素B1，在烧好后温热的过程中，可损失25%．烧好的白菜若温热15分钟可损失维生素C20%，保温30分钟会再损失10%，若长到1小时，就会再损失20%，假若青菜中的维生素C在烹调过程中损失20%，溶解在菜汤中损失25%，如果再在火上温热15分钟会再损失20%，共计65%．那么我们从青菜中得到的维生素C就所剩不多了．

    ②含有多种氨基酸的食品都是高级营养品：氨基酸本身并没有什么神秘之处，它只是蛋白质的组成单元．食品中含有蛋白质，也自然含有氨基酸．廉价的玉米和土豆中照样含有多种氨基酸．健康人既然具有消化蛋白质的能力，就完全可以从普通食物中获得氨基酸，也就没有必要喝什么昂贵的氨基酸营养液．

    ③吃素更有利于健康：时下素食的人越来越多，这对防止动脉硬化无疑是有益的．但是不注意搭配、一味吃素也并非是福．现代科学发现吃素至少有四大害处：一是缺少必要的胆固醇，而适量的胆固醇具有抗癌作用；二是蛋白质摄入不足，这是引起消化道肿瘤的危险因素；三是核黄素摄入量不足，会导致维生素缺乏；四是严重缺锌，而锌是保证机体免疫功能健全的一种十分重要的微量元素，一般蔬菜中都缺乏锌．

    ④不是米越白质量越高：米的洁白程度和米外层的米糠有关，米糠去除程度越高，米越白，营养损失也越多．米糠中含有丰富的B族维生素和膳食纤维，米的胚芽含有维生素E和许多不饱和脂肪酸．经常食用精白米的人容易发生维生素B1和维生素B2的缺乏，因此，米不是越白越好．

    ⑤鸡蛋蛋壳颜色越深营养价值越高：有人认为红壳蛋壳比白蛋壳营养价值高，这是错误的．蛋壳的颜色因产蛋鸡的品种而异．科学家的实验证明，把产红壳蛋和产白壳蛋的两种鸡在同等条件下喂养，产下的鸡蛋营养成分是一致的．评价蛋白的品质，主要是蛋白（蛋清）中蛋白质的含量．从感官上看，蛋清越浓稠，表明蛋白质含量越高，蛋白的品质越好．

    ⑥喝汤不吃“渣：有人做过实验，用鱼、鸡、牛肉等蛋白质含量不同的食品原料煮6小时后，看上去汤已很浓，但蛋白质的溶出率只有6%﹣15%，还有85%以上的蛋白质仍留在“渣”中．经过长时间烧煮的汤，其“渣”吃起来口感虽不是最好，但其中的肽类、氨基酸更利于人体的消化吸收．因此，除了吃流质的汤以外，还应提倡将汤与“渣”一起吃下去．

    ⑦标有“不含胆固醇”字样的油才是好油：“不含胆固醇”这个标记只不过是一个广告用语而已．在植物油里原则上是不可能没有胆固醇的!在精炼植物油的过程中，胆固醇不可能从油脂中被去掉．但是，在植物油中，胆固醇的含量与猪油和黄油相比，其数值还是很低的．要知道动物油的胆固醇含量大概是植物油的10﹣25倍左右．

The old dog thinks, “Oh, oh! I'm in deep3now!” Noticing some bones on the ground close by, he4settles down to chew on the bones with his back to the5leopard.

    Just as the leopard is about to6 the old dog exclaims loudly, “Boy, that was one delicious leopard! I7if there are any more around here?” Hearing this, the young leopard stops his attack in mid-strike, a look of8comes over him and he runs back into the trees. “Whew!”, says the leopard, “That was close! That dog nearly9me!”

    Meanwhile, a monkey who had been10the whole scene from a nearby tree decides that he can put this knowledge to good use and trade it for11from the leopard. So off he goes … but the old dog sees him12the leopard and figures that something must be up. The monkey soon catches up with the leopard, and explains that the dog is13and strikes a deal with the leopard.
