关于健康饮食的演讲稿
健康饮食金字塔是建立在每日运动和控制体重的基础之上的,因为这两个因素对人们保持健康来说,十分重要。
它们也会影响到人们吃什么和如何吃的问题,以及人们吃的食物又如何影响自身的健康。
从健康饮食金字塔的底座往上看,其中包括: 全麦食品(在大部分进餐中) 人体需要碳水化合物提供能量,碳水化合物的最佳来源是全麦,比如燕麦片、粗面面包、以及玄米(也就是糙米)。
它们含有麸糠和胚芽,以及富含能量的淀粉。
人体消化全麦的时间要比消化白面包这样直接的碳水化合物长,这会使人体的血糖和胰岛素保持在一个合理的水平,并很快会下降。
很好地控制血糖和胰岛素水平,能够减少人体的饥饿感,阻止Ⅱ型糖尿病的发生。
植物油。
美国人平均每天从脂肪中获取1/3的日需卡路里,所以,把它们放在金字塔的下部是有道理的。
注意,这里特别指明的是植物油,并非全部各类脂肪。
健康的不饱和脂肪来自橄榄、大豆、玉米、向日葵、花生和其他植物油,以及富含脂肪的鱼类,比如三文鱼等。
这些健康的脂肪不仅改善人体胆固醇水平,而且还能有效防止潜在的心脏猝死和心肌梗死等。
蔬菜(大量的)和水果(每日2到3次)。
多吃蔬菜和水果可以有效防止心脏病和心绞痛的发生;预防各种癌症;降血压;减轻被称作憩室炎的肠道疾病;防治白内障和青光眼,对65岁以上的老人来说,这两种眼疾是造成老年失明的主要病因。
鱼、禽、蛋(每日0到2次)。
这是蛋白质的主要来源。
大量的研究表明,吃鱼可以减少心脏病的危险。
肌肉和火鸡的饱和脂肪含量低,也是很好的蛋白质来源。
鸡蛋是长期被妖魔化的食物,因为它的胆固醇含量相对较高,实际上,鸡蛋是很好的早餐,它比油炸甜面包圈或者精面面包圈要好得多。
坚果和带壳豆(每日1到3次)。
坚果和带壳豆是植物蛋白、植物纤维、维他命和矿物质的最佳来源。
带壳豆包括黑豆、蚕豆、毛豆等干货。
很多坚果含有丰富的健康脂肪,比如,杏仁、核桃、小胡桃、花生、榛子、松子等可以直接标明该食物有益于心脏。
奶制品和代用钙(每日1到2次)。
为防治骨质疏松,需要摄入钙、维生素D等,奶制品是美国人获得钙的传统来源。
除了牛奶和奶酪这类含有饱和脂肪的食品外,还有其他的健康方式获取钙。
例如,三杯全脂牛奶相当于十三小条熟熏肉所含的饱和脂肪。
如果你喜欢奶制品,可坚持选择脱脂或者低脂产品。
如果你不喜欢奶制品,代用钙食品是保证每日人体钙需求量的保证。
红肉和奶油(小心使用): 这些食物被放在健康饮食金字塔的上层,因为它们含有丰富的饱和脂肪。
如果你每天都吃红肉,如牛羊肉等,每周尝试几次鱼或者鸡肉可以改善你的胆固醇水平。
同样的,你也可以从奶油换到橄揽油。
大米、白面包、土豆、意大利通心粉、甜品(慎用): 为什么这些全美国人的主食被放在了健康饮食金字塔的顶端
因为它们会引起人体血糖的迅速提高,导致体重增加,糖尿病、心脏病和其他慢性病的发生。
全麦碳水化合物则使人体血糖稳定,至少是缓慢增长而不会超过人体正常水平,使人体有能力处理多余的血糖。
多种维生素: 日常多种维生素,多种矿物补充物是人体的营养后备。
我们每天吃的食物有时不能提供人体日常所需的所有营养元素,这时多种维生素可以为那些哪怕是最谨慎小心的食客填补营养缺口。
请选择正牌的多种维生素。
酒精类(适量): 每天少许喝点儿酒,可以降低心脏病的危险。
适量是很重要的,酒精是双刃剑,危害与益处同在。
对于男人来说,平衡点是每天喝1到2杯,这可不是指扎啤杯。
对女人来说,每天一杯足够了。
健康饮食金字塔总结了当今最好的饮食情报,它不是空中楼阁,或者一成不变,随着时代的发展,研究的深入与多样化,健康饮食金字塔会与时俱进地反映最新、最重要的研究成果。
十种最佳饮食搭配法 桌上要讲究搭配,正确的搭配可以让我们获得更多营养。
错误搭配不仅会让食品失去营养,甚至会让身体受到危害。
鱼+豆腐 作用:味鲜,补钙,可预防多种骨病,如儿童佝偻病、骨质疏松症等。
原理:豆腐含大量钙质,若单吃,其吸收率较低,但与富含维生素D的鱼肉一起吃,对钙的吸收与利用能起更佳效应。
猪肝+菠菜 作用:防治贫血。
原理:猪肝富含叶酸、维生素B12以及铁等造血原料,菠菜也含有较多的叶酸和铁,同食两种食物,一荤一素,相辅相成。
羊肉+生姜 作用:冬令补虚佳品,可治腰背冷痛、四肢风湿疼痛等。
原理:羊肉可补气血和温肾阳,生姜有止痛祛风湿等作用。
同食,生姜既能去腥膻等滋味,又能有助羊肉温阳祛寒。
鸡肉+栗子 作用:补血养身,适于贫血之人。
原理:鸡肉为造血疗虚之品,栗子重在健脾。
栗子烧鸡不仅味道鲜美,造血功能更强,尤以老母鸡烧栗子效果更佳。
鸭肉+山药 作用:补阴养肺,适于体质虚弱者。
原理:鸭肉补阴,并可消热止咳。
山药的补阴作用更强,与鸭肉伴食,可消除油腻,同时可以很好地补肺 瘦肉+大蒜 作用:促进血液循环,消除身体疲劳、增强体质。
原理:瘦肉中含有维生素B1,与大蒜的蒜素结合,不仅可以使维生素B1的析出量提高,延长维生素B1在人体内的停留时间,还能促进血液循环以及尽快消除身体疲劳、增强体质。
鸡蛋+百合 作用:滋阴润燥,清心安神。
原理:百合能清痰火,补虚损,而蛋黄能除烦热,补阴血,同食可以更好地清心补阴。
以健康饮食为主题的演讲稿
大家好! 今天我演讲的题目是《从我做起,拒绝垃圾食品》。
新春佳节刚刚过去,压岁钱噼里啪啦地落进了同学们的口袋里,一定装得鼓鼓的吧。
用来买什么呢?相信很多同学会选择买吃的。
俗话说,爱“吃”之心人皆有之。
可是,让我们感到恐怖的是,现在大家爱吃的“食品”前面常常有个定语“垃圾”!连起来就是——垃圾食品! 你一定会说,“我才不吃垃圾呢?” 别急,下面请大家跟我一起回想这个场景:每当学校放学时,我们总会发现校外的小店里、小摊上中挤满了人。
各式各样的糖果、油炸食品和琳琅满目的膨化食品都是同学们的抢手货。
如果你说在放学那一幕里没有你的身影,想想你有没有缠着爸爸去麦当劳、肯德基,有没有要求妈妈买各种饮料而拒绝白开水,有没有咔嚓咔嚓、香喷喷地啃方便面呢?!请看世界卫生组织公布的垃圾食品大家庭的十位主要成员:油炸类食品,腌制类食品,肉类加工食品,饼干类食品,汽水可乐食品,方便类食品,罐头类食品,冷冻甜食类食品,烧烤类食品。
怎么样,相信在座的各位同学都中招了吧。
遗憾的是,以上食品都是同学们的最爱。
大家只知道这些食品美味可口,却不知道许多食品含有致癌物,有些会破坏维生素,汽水和可乐含有磷酸和碳酸,会带走人体内大量的钙……所以垃圾食品象毒品一样正侵害着我们的身体健康,它使很多小朋友欲罢不能。
更不用提那些包围在学校周围的“三无”垃圾食品了。
下面请事实说话——据报道:这些没有生产许可证、没有生产厂家,没有生产日期的“三无”食品,生产场所更是环境差、条件简陋:地上乱七八糟的摆放着一堆堆的半成品,一桶桶的地沟油,一罐罐花花绿绿的色素,一袋袋来历不明的添加剂,散发出刺鼻难闻的味道,引得一群苍蝇到处乱飞。
更让人恶心的是,为了让小食品更有劲道,工人就直接用脚在辣条上踩来踩去;许多做辣条的工人,由于长时间手与这些化学颜料接触,手都掉皮、腐烂了。
同学们,垃圾食品会给我们带来多么巨大的伤害啊!你们还敢吃吗?尤其是小学生,正处于生长发育的黄金阶段,需要丰富的营养,比如新鲜的蔬菜、水果、牛奶等。
为了我们自己的健康,为了更好地学习、快乐地成长,为了不让老师和家长为我们担心,我再一次呼吁——让我们一起行动起来,杜绝垃圾食品,倡导健康的饮食方式! 谢谢大家!

The students in our class have different suggestions.Some students think that we can collect money to buy some books for the school library or something else for the school. Other students think that it’s not necessary to spend money, because we can study hard and make our school feel proud of us.In my opinion, we don’t have to spend money. We can do something meaningful without money. For example, we can do some voluntary work to beautify the school’s environment or try to get better results in the coming exams so that our school will be proud of us. (In my opinion, we can collect our pocket money to buy some books for our school library. We can buy some detective stories and English novels, which don’t cost much but they are useful and are popular with the younger students. I hope every student in our school can do so.)I’d like to know your idea. Could you give me some advice?Best wishes,Li Ming书面表达(四)青少年饮食是影响民族人口素质的重要因素,但是目前部分青少年的饮食状况令人担忧。

饮食习惯英语演讲稿3分钟至5分钟。
同学们: 大家好
今天我要与大家分享的是关于的问题。
俗话说得好:国以民为本,民以食为天。
食品是人类生存的第一需要,直接关系着人民群众的生活,影响我们每一个人的健康,更关系着子孙 后代的幸福和民族的兴旺昌盛。
不讲,哪怕是,一根豆芽,都 能让你身体残缺;不懂食品安全,哪怕是小小的一包盐,就能中断免疫系统的正 常运行;不要食品安全,哪怕只是小小的一个意念,就能让生机勃勃的生命处于 危险之中。
健康,何等重要
生命,何等珍贵
一旦我们失去了健康,甚至是失去了宝贵的生命,我们不可能再重来一次。
所以我们要时刻维护自己的健康,珍爱自己的生命,而食品安全则是生命健康最 有力的保证。
求科学饮食,健康生活的高中英语演讲稿,三分钟左右
Everyone wants to maintain good health, if you are healthy, then you can do you want to do anything, your family will be full of laughter, your work will be much more simple. You want to have a healthy body? Then try to do the following thing! First, you face daily smile, maintain a good mood. Take part in some sports, such as running,playing baseball. It is in a strong body. Secondly, we must pay attention to our diet, not to drink too much wine, water, every day at least eight cups of water; Deliberately not to lose weight, did you have no health benefits. Again, resulting from smoking on your own and other people is not good! To maintain good health let us do it. Others can take away our money, house, car, or even our clothes and we can survive. But if our health was taken away, we would surely die. That is why we always try to eat in a healthy way and exercise regularly. Living a long life may be a lot easier than you think. And there are some bad habit we need to get rid of 。
A report suggests 10 steps to a longer and healthier life. 1. Shun cigarette smoke, separate yourself from smokers. . Become a nag and tell anyone you know who smokes to stop. 2. Keep moving. The U. S. Department of Health and Human Services suggests every adult get at least 150 minutes of moderate aerobic activity a week. Sessions should be at least 10 minutes long. 3. Eat like an Aegean. Follow the Mediterranean diet pattern of mostly plant foods, limiting animal protein to fish and poultry, using olive oil as the principal fat and use wine in moderation. 4. Mind your body mass index. Obesity increases the risk of diabetes 20 times and substantially boosts the risk of developing high blood pressure, heart disease, stroke and gallstones. 5. Lift a glass, but only one. Alcohol's effects become more insidious as women age because the body's water-to-fat ratio declines over the years. 6. Don't run up a sleep debt. Medical evidence suggests we need seven to nine hours of sleep daily, but more than 60 percent of women regularly fall short of that goal. 7. Be your own best advocate on health issues. 8. Keep connected. Older women who remain socially active live longer and healthier lives than their solitary counterparts 9. Avoid stress. Find techniques to reduce stress and its effects. 10. Use supplements selectively. Experts agree the best way to get nutrients is through food. Only calcium and vitamin D, essential in preserving bone density, are recommended supplements. And that includes 1,200 mg of calcium and 1,000 mg of vitamin.
