Smoking is a bad habit that does harm to smoker and others. Many kinds of diseases and cancers are caused by smoking, such as tracheitis, lung cancer and many other diseases. Recent years, there are tens of thousands of people dying of smoking. But there still are many people enjoying smoking, because they think smoking is a kind of fashion and smoking is so cool, especially among teenagers. In addition, smoking does harm to others as well. Second hand smoking has been recognized harmful to other people. Even worse, it may cause more damages. Therefore, people should remember that smoking is harmful to others and those people who smokes should give up smoking as soon as possible.
吸烟是个坏习惯,它对吸烟者和别人都有害。很多疾病和癌症是有吸烟引起的,比如说气管炎,肺癌还有很多其他疾病。近年来,成千上万的人死于吸烟。但是仍然有很多人喜欢吸烟,因为他们认为吸烟是一种时尚,很酷,特别是青少年。另外,吸烟也会对别人有害。二手烟是公认的对别人有害的。更糟糕的是,它会带来更多伤害。因此,人们应该牢记吸烟有害他人,那些吸烟的人应该尽可能戒烟。
饮食,我认为主要是一日三餐。人在生活中每天身体内需要的营养就来源于三餐之中,为学习工作提供能量。所以,人们常说:“早餐要吃好,午餐要吃饱,晚餐要吃少”这一养生经验是有道理的。
早餐不但要注意数量,而且要讲究质量。主食一般吃含有淀粉的食物。如:牛奶、豆浆、鸡蛋等,能使体内的血糖迅速升高到正常或超过正常标准,从而使人精神振奋,精力充沛的.工作或学习。对经常不吃早餐的人来说,不但工作或学习达不到精力充沛的最佳状况,还容易发生胆结石。
午餐应适当多吃些,而且质量要高。主食一般是米饭、馒头、面条等,副食品增加些富含蛋白质和脂肪的食物,如:鱼类、肉类、蛋类和豆制品等,以及新鲜蔬菜。使体内血糖继续保持在高水平,以保证下午的工作或学习。否则,如果因工作或学习紧张,会把脑中供应的这些神经传递消耗殆尽,供不应求,就会影响工作或学习。
晚餐要吃得少,应以清淡,容易消化为原则,至少要在睡觉前两小时进餐。如果晚餐吃得过多,并且吃进大量含蛋白质和脂肪的食物,不容易消化,也会影响睡眠。
另外,无论工作或学习再忙再紧张,吃饭一定要做到定时定量,不要暴饮暴食。这样会有利于肠胃有规律并正常工作,否则,容易造成消化不良,对身体更为不利。
总之,一日三餐要巧安排,养成良好的饮食习惯,从食物中摄取营养物质,以保证身体的健康。
俗话说:“民以食为天。”食品好坏与我们健康是分不开的,所以吃东西要吃些有营养又健康的,比如:蔬菜、水果……,吃蔬菜要吃绿色蔬菜,可以提高营养,补血。吃水果可以补充维生素。
不要吃垃圾食品,特别是学校门口的食品店里的食品:辣条、薯片、冰棒等等,红的、橙的、灰的,样样都有。有许多小朋友都一块、两块地买来吃。其实这些食品是对人有很大伤害的。
最近,我看见一则新闻,就是关于健康饮食的。有个小孩才5岁,他住在他的爷爷家,有一天他和爷爷去散步,他突然看见一个人在喝可乐,爷爷心疼孙子,就买了一瓶给他喝,就从那以后,他就一直把可乐当水喝,而且晚上从来都不刷牙,没过两年,他就被送进了医院,医生在检查时,几乎都看不到他的牙齿。因为,他的牙齿已经被可乐一颗一颗地“吃掉”了。
还有一件事故发生在自己身上,就是在一个严热的夏天热的仿佛大地都裂了一样,我被热得实在不行了,我就跑进厨房,打开冰箱拿出四五个雪糕,不一会儿全被我吃光了,结果我晚上就拉肚子了。我问妈妈为什么,妈妈说:“因为你一下子吃太多雪糕了,胃消化不了,受了冷食物的刺激。”我恍然大悟。
所以小朋友们千万不要吃垃圾食品,也不要爆饮爆食,因为这些都会应影响我们的身体健康哦!
