健康饮食 吃饭是再也平常不过的事,然而人类通过漫长的历程才从“吃饱求生存”发展到懂得“吃好求健康 ”
要想身体健康,保持良好的饮食习惯非常重要。因为人之所以能够维持生命、工作、思维,都依靠食物中的营养供应. 著名的维多利亚宣言提出健康生活方式的四大基石——即“合理膳食、适当运动、戒烟限酒、心理平衡”,居于首位的就是合理膳食。中华民族自古就有“寓医于食”的传统,食疗养生的理念被人民群众广泛接受。“饮食者,人之命脉也”。则是明代医药学巨匠李时珍对膳食营养的健康作用所做的高度概括。

平衡、健康的膳食结构在东方、在中国 20世纪,营养学的最大贡献是建立了平衡膳食的理论。所谓平衡膳食,就是强调由多种天然食物组成的膳食,可提供人体基本的营养需要,在支持正常发育、保持合适体重,预防营养不良的同时,减少同营养过剩相关疾病的发生 《中国居民膳食指南》 一、食物多样,谷类为主; 二、多吃蔬菜、水果和薯类; 三、每天吃奶类、豆类或其制品; 四、经常吃适量鱼、禽、蛋、瘦肉,少吃肥肉和荤油; 五、食量与体力活动要平衡,保持适宜体重; 六、吃清淡少盐膳食; 七、饮酒要适量; 八、吃清洁卫生、不变质的食物。

文明病 常言道“病从口入”,过去多半指吃了不洁的食物得病,现在它的涵义广泛了,即因食物结构不合理而引起的慢性非传染性疾病也包括在内
常言道“病从口入”,过去多半指吃了不洁的食物得病,现在它的涵义广泛了,即因食物结构不合理而引起的慢性非传染性疾病也包括在内 营养过剩正在危害健康,各种致命的慢性病——肥胖、高血压、高血脂、冠心病、脂肪肝、动脉硬化、糖尿病等发病率大幅度提高。 近十几年来,随着经济的发展,国人膳食结构发生明显变化。以上海为例:1992年该市城乡居民粮食摄入量比1982年减少了22%,动物性食物的消费增加了1.5倍,其中畜肉上升了3.6倍、乳制品增加了5倍,油脂消费增加约70%;吃高热量、高脂肪、高蛋白质的“洋快餐”,喝含糖洋饮料日趋普遍。脂肪提供的热量从1959年的9%上升到27%,超过全国城市平均水平(25%),并已高于日本(24%)。与此同时,恶性肿瘤、脑血管病、心脏病已成为该市头三位死亡原因,与饮食营养关系最密切的心脏病死亡率已超过日本,与战后日本的变化极为相似。这一切都非常清楚地说明:随着膳食结构“西化”,“文明病”已登陆中国。

“洋快餐”进军中国,“垃圾饮食”危害健康!
2002年2月15日,埃菲社记者 发自北京的报道:“中国传统深受西方风尚冲击”,文章说:“从战国时代以来的数千年中,中国的古老传统一直得以保存,但现在却仿佛屈服于不可抗拒的西方生活方式。……从美国那里,他们模仿到的是最糟糕的东西——“洋快餐”。中国已是麦当劳、肯德基在全球的第二大市场”。2002年1月14日美国《基督教科学箴言报》题为“中国胖子在忙着减肥”的文章尖锐地指出:“汹涌而来的‘洋快餐’是造成这一局面的主要原因”。
16
“快餐咬了中国文化一口” 在中国、41%的受访者每周至少要吃一次“洋快餐”,而在美国这个数字为35%。文章披露:麦当劳在中国105个城市有600多家分店;肯德基炸鸡店在中国则拥有1200家分店,2004年一年新开了270家分店,2005年至少还要开张200家。文章说:“中国目前约有两亿人体重超重,600万人肥胖。公共医疗专家认为,‘洋快餐’消费日益增多是造成中国糖尿病和高血压发病越来越多的首要原因。”
17
.“洋快餐”危及食品慢性安全 纽约时报》题为“所有的‘进步’都在渐渐危害生命” 的文章指出:正是由于美国社会底层的穷人大量食用“垃圾食品”——双料三明治、鸡肉汉堡包、特大匹萨饼(必胜客)、大包装的油炸土豆条等,使他们成为美国最容易发胖的人群。美国国民普遍肥胖的现实,反映出西方社会取得的“进步”具有深刻内在的矛盾性。2000年因饮食不当和缺少运动,导致10万美国人死亡,在美国死于肥胖的人数是死于传染病人数的5倍。一则西方媒体的漫画,在汉堡包、热狗、炸薯条、冰淇淋等“洋快餐”旁边写着:“我们杀死的美国人和香烟杀死的一样多!”。美国联邦疾病控制中心(CDC)指出:“目前有64%的美国人体重严重超标,肥胖对健康的危害不久将超过烟草、成为美国的首位死因 .

关注食疗——“寓医于食” “国以民为本,民以食为天”。科 学、合理的膳食结构与民族昌盛、国家繁荣息息相关。我们的祖先为了生存,尝百草、吃野果,在与自然界的斗争中,体会到许多食物和防病、治病有不解之缘。中华民族在九千年前就掌握了酿酒术,酒既可作饮料,又可活血、养气、暖胃、驱寒,中医素有“医源于酒”之说。自古以来,“食用、食养(食补)、食疗(食治)、食忌(食禁)”这些贯穿日常生活的膳食原则,使“药食同源,寓医于食”的理论得到了广泛的实践。作为世界四大文明古国之一,中国在灿烂的文化遗产中积累了世代相传的、应用食疗强健体魄、抵御衰老、延年益寿的丰富经验。这一运用膳食防治疾病的生活内容不仅使中华民族繁衍昌盛,也造就了华夏古老文明的成就之一。
