为什么每天必须吃2斤新鲜蔬菜 蔬菜是人们生活中必不可少的食物之一。但是,对于蔬菜的营养价值,有些人却了解得不甚清楚。 蔬菜的营养不可低估众所周知,蔬菜可提供人体所必需的多种维生素和矿物质,1990年国际粮农组织统计人体必需的维生素C的90%、维生素A的60%来自蔬菜,可见蔬菜对人类健康的贡献。此外,蔬菜中还有多种多样的植物化学物质是人们公认的对健康有效的成分,如:类胡萝卜素、二丙烯化合物、甲基硫化合物等。目前果蔬中的营养素可以有效预防慢性、退行性疾病的多种物质正在被人们研究发现。 据估计,目前世界上有20多亿或更多的人受到环境污染而引起多种疾病,如何解决因环境污染产生大量氧自由基的问题日益受到人们关注。解决的有效办法之一,是在食物中增加抗氧化剂协同清除过多有破坏性的活性氧、活性氮。研究发现,蔬菜中有许多维生素、矿物质微量元素以及相关的植物化学物质、酶等都是有效抗氧化剂,所以蔬菜不仅是低糖、低盐、低脂的健康食物,同时还能有效的减轻环境污染对人体的损害,同时蔬菜还具对各种疾病的预防作用十字花科甘蓝类蔬菜:如青花菜、花菜、甘蓝、叶甘蓝、芥兰等含有吲哚类(13C)萝卜硫素、异硫氰酸盐、类胡萝卜素、维生素C等,对防治肿瘤、心血管病有较好的作用,特别是青花菜。 豆类中,如大豆、毛豆、黑豆等所含的类黄酮、异黄酮、蛋白酶抑制剂、肌醇、大豆皂苷、维生素B,对降低血胆固醇调节血糖,减低癌症发病及防治心血管、糖尿病有良好作用。 芦笋含有丰富的谷胱甘肽、叶酸,对防止新生儿脑神经管缺损,防肿瘤有良好作用。 胡萝卜中含有丰富的类胡萝卜素及大量可溶性纤维素,有益于保护眼睛提高视力,可降低血胆固醇,可减少癌症与心血管病发病。 葱蒜类蔬菜,有丰富的二丙烯化合物,甲基硫化物等多种功能植物化学物质,有利于防治心血管疾病,常食可预防癌症,还有消炎杀菌等作用。 茄果类蔬菜,番茄中丰富的茄红素高抗氧化剂能抗氧化,降低前列腺癌及心血管疾病的发病。茄子中含有多种生物碱,有抑癌、降低血脂、杀菌、通便作用。辣椒、甜椒含丰富维生素、类胡萝卜素、辣椒多酚等,能增强血凝溶解,有天然阿司匹林之称。但一个人每天要食用多少新鲜蔬菜才能保证人体所需的各种维生素和各种微量元素的摄入呢?根据相关国家的医学机构研究表明:每天至少要服用1000克左右的蔬菜。现代生活的节奏不断加快,生活在城市中人群的由于工作、学习的压力不断加大,日常生活中很少能维持每天有健康、营养的饮食,更不用说每天去吃1000克左右的新鲜蔬菜了,国外的蔬菜晶所起到的作用就是:通过对各种蔬菜的有效成分的浓缩提取制剂,每天服用1袋及可补充人体所需的各种蔬菜营养。

The Ten CommandmentsMoses called together all the people of Israel and said to them, "People of Israel, listen to all the laws that I am giving you Learn them and be sure that you obey At Mount Sinai the Lord our God made a covenant, not only with our fathers, but with all of us who are living There on the mountain the Lord spoke to you face-to-face from the I stood between you and the Lord at that time to tell you what he said, because you were afraid of the fire and would not go up the "The Lord said, 'I'm the Lord your God, who rescued you from Egypt, where you were "Worship no god but ""Do not make for yourselves images of anything in heaven or on earth or in the water under the Do not bow down to any idol or worship it, for I am the Lord your God and I tolerate no I bring punishment on those who hate me and on their descendants down to the third and fourth But I show my love to thousands of generations of those who love me and obey my ""Do not use my name for evil purposes, for I, the Lord your God, will punish anyone who misuses my ""Observe the Sabbath and keep it holy, as I, the Lord your God, have commanded You have six days in which to do your work, but the seventh day is a day of rest dedicated to On that day no one is to work—neither you, your children, your slaves, your animals, nor the foreigners who live in your Your slaves must rest just as you Remember that you were slaves in Egypt, and that I, the Lord your God, rescued you by my great power and That is why I command you to observe the S""Respect your father and your mother, as I, the Lord your God, command you, so that all may go well with you and so that you may live a long time in the land that I am giving ""Do not commit ""Do not commit ""Do not ""Do not accuse anyone ""Do not desire another man's wife; do not desire his house, his land, his slaves, his cattle, his donkeys, or anything else that he " 注:《十诫》选自《旧约》的“申命记”(Deuteronomy)。中世纪以来,在基督教教会的极力推行下,“十诫”成为传统西方社会的道德准则,对西方文化产生了深远的影响。如果把它的具体内容同中国文化的传统价值观作一比较,我们不难发现它们之间存在着明显的异同。一方面,中西文化泾渭分明。前者表现出入世的、宽容的特征,如孔子不谈“怪、力、乱、神”,中国人“见神就拜”,相信“八仙过海,各显神通”;后者则表现出强烈的出世与排他倾向,这一点在第1—4诫中可以看出。另一方面,中西文化也具有共同的道德追求,第5—10诫可以为证。当然,当代中西文化均已发生很大变化,这一点,还望读者明察。
