1、国旗下讲话稿合理饮食，健康成长敬爱的老师们，亲爱的同学们：早上好：我今天国旗下讲话的题目是：“合理饮食，健康成长”。每年的5月20日是“全国学生营养日”，这项宣传活动得到广大师生、家长的欢迎和许多营养学专家的积极参与、支持。随着生活水平的提高，中小学学生中挑食、厌食、偏食者日益增多，很多学生都养成了喜吃零食、不爱吃主食的习惯，导致学生中营养不良者日益增多。我们经常看到一些同学根据自己的口味和喜好进餐，喜欢吃的菜加了还嫌少，不喜欢的吃的菜不动筷子，整份整份的倒掉。有些同学偏爱吃肉，没有肉就没食欲。有些同学对香辣刺激的食物爱不释口。还有些同学把方便面、羊肉串等烧烤或油炸食品、膨化食品等世界卫生组织

2、公布的“垃圾食品”当成自己的最爱、甚至用其替代正常的一日三餐。如此等等挑食、偏食的饮食习惯导致我们身体发育所需要的各种营养物质得不到有效补充，长期下去就造成了膳食结构单一，严重影响了体能与智能发育，甚至引发许多健康问题。由此可见健康饮食是多么重要。那么，怎样做到健康饮食呢？首先我们要高度重视一日三餐，做到定时、定量、科学合理搭配。人们在长期的生活实践中总结为“早吃好，午吃饱，晚吃少”的进餐经验，并且妇孺皆知。所谓“好”是指质量要好，早晨起来胃肠已排空，急需食物补充，但此时食欲不是很好，吃好才更有利于丰富营养物质的吸收；我们有些学生早晨匆匆忙忙凑（）合着吃一点、甚至不吃就赶着上课，上了两节课，肚

3、子就空了。等到第三、四节课就出现精神不振、注意力不集中等现象，影响正常的学习。“饱”是指数量要足，午饭是承上启下的中转站，人有良好的食欲，胃肠有良好的功能状态，故要吃饱，以保证有足够的能量供应；“少”是指数量和质量均要有所控制。晚饭吃少不会加重胃肠负担，也不会造成多余脂肪的堆积。除保证好一日三餐外，我们还应注意以下几方面：1.注意饮食卫生。不去路边摊买油炸食品或小吃。我们可以清楚地看到：街头食品加工者的构成十分混杂；经营设施十分简陋，卫生防护设施不健全；空气中的细菌随时在污染食物；街头食品卫生根本无法得到保证，食品卫生安全存在很大问题。2.少吃油炸和暴晒食品，远离洋快餐。3.多食增强记忆力食品

4、。如香蕉富含矿物质钾，可预防精神疲劳；卷心菜、葡萄、蛋黄对增强记忆力都有一定的帮助。4.多吃高热量的食品。中小学生对热量的需要比成人高，每天应保证足够的主食。5.应补充钙，铁，碘，锌等元素。这几种元素是中小学生在青春发育期需要较多也最易缺乏的。中小学生在快速长高的过程中，需要大量的钙、磷来补充，应多选含钙、磷的蔬菜、豆类、海产品和乳类，每天喝一杯牛奶或豆浆可获得较多的钙和蛋白质。6.注意补充各种维生素。因中小学生用眼多，维生素A供应充足有助于保护视力，又可预防呼吸道感染；维生素B与机体能量消耗有关；维生素C可促进铁的吸收。7.不要挑食。合理营养对青少年健康成长及学习有着很重要的意义。中小学生活

5、动量大，学习又紧张，在这一时期里，需要多种食物的有机营养结合。目前，我们学校的食堂每天的菜，都是根据你们的身心健康发展需要合理搭配的，打到餐盘的菜要尽量吃完，不要浪费。8.不要用垃圾食品代替正常餐饮，不要为了贪玩而错过了宝贵的就餐时间，不食用过多零食（尤其是彩色食品）。9.在科学、认真地吃好每一顿饭的同时多参加体育运动来锻炼身体。因为饮食平衡还包含了饮食和消耗的平衡。如果每天吃得多，动得少，那么，吃下去的各种食物，就会转化成脂肪，贮存在体内。这样，人会越来越胖。人胖了，体重超标了，就容易导致各种疾病的发生。所以，人要进行适当的锻炼，锻炼能帮助消耗体内的能量，还能强身健体，锻炼肌肉和骨骼。当然，

6、体重过轻对身体健康同样不利，严重的还会影响青少年的生长、发育。维持身体健康和正常体重的最佳方法，就是从小养成良好的饮食习惯，每天进行适当的体育锻炼，做到体内热能大致平衡。同学们，健康的饮食生活对我们的身心健康和我们的成长发育是十分重要的，是我们学习生活的基本保证。我们应该注重生活中健康的每个细节，用最健康的体魄、最饱满的精神状态去迎接每一天的学习，去创造美好的未来。我的讲话完了，谢谢大家。QcWA3PtGZ7R4I30kA1DkaGhn3XtKknBYCUDxqA7FHYi2CHhI92tgKQcWA3PtGshLs50cLmTWN60eo8Wgqv7XAv2OHUm32WGeaUwYDIAW
