Knowledge is all about in term of this topic to make good judgment: See some comments inserted below the following each arguments.
美国大豆是转基因豆,这种豆美国人自己不吃,欧洲、日本等发达国家也不吃这种豆油,因为这种转基因食品吃下去对人有什么危害,现在还不是完全十分清楚。但根据一些线索分析,近年来世界流行的各种怪病,很可能与转基因食品有关,我国大量进口转基因大豆,很有可能相当于第二次进口“鸦片”。而且危害还有可能超过“鸦片”,因为“鸦片”你可以拒绝吸食,但转基因大豆油太多了,你在家不吃,去食堂、餐馆吃饭,就不可避免地吃转基因大豆油。
First of all, majorities of transgenes are native to plants. 美国大豆是转基因豆,这种豆美国人自己不吃 is totally nonsense. How do we know we, in US, are not eating 转基因豆, since there is no label requirement for any transgenic agricultural products.
If this is the case, how about milk most of us are drinking everyday? Cow are feed with some transgenic corn plants and forced to make more milk by horm.. stimulus
根据几年来的科学研究,转基因大豆可能对人体产生以下几种危害:
1、转基因大豆及其产品可能对人体产生过敏反应。全世界有近2%的成年人和4%—6%的儿童发生过食品过敏,而90%的过敏是由蛋、鱼、贝壳、奶、花生、大豆、坚果和小麦8种食物引起的。转基因大豆由于其引入外部基因所以可能对人体更容易产生过敏反应。世界上一些国家的事实也证实了转基因大豆存在一定过敏性。
All transgenes introduced into wide type soybean varieties are not analog to any known allergens to human being. These transgenic varieties otherwise would not be approved by US and other country's regulatory agencies such as FDA and USDA.
2、转基因大豆及其产品可能会影响人体健康和内部系统。转基因大豆的组成物质与非转基因大豆相比有较大的变化,如植物凝血素提高了约1倍,蛋白酶抑制剂高26.7%,而蛋白质和苯丙氨酸明显下降,维生素B2复合体胆碱的含量低29%等,这些组成物质的变化可能会使人体生长缓慢;转基因大豆还含有一种类似雌性激素钓化学物质,它会影响人体荷尔蒙,导致人体生殖器官异常,并损害免疫系统。此外,有证据表明,转基因大豆食品与非霍奇淋巴瘤发病率的提高具有一定相关性。
There could be some side effects to certain group of people from any transgenic products, similar to some kind of side effected some medicines have.
3、转基因大豆及其产品可能会影响人体对抗生素产生抗性。转基因大豆中引人了外部基因,如果这些抗生素标记基因进入人体,则有可能转移到有害的致病菌中,从而使它们产生耐抗生素的能力,降低抗生素的临床有效性,也可能使人体对很多抗生素产生抗性。
Is there any transgenic soybean containing any antibiotics gene? If yes, government agencies definitely did not do the job. The author does not have any knowledge of whole chain from lab to regulatory to farmer to market.
4、转基因大豆及产品可能引起跨物种感染,使人类感染动物的疾病,带来严重灾难。转基因食品中引入特定的基因或病毒,为跨物种感染埋下了通道。尽管转基因食品引起跨物种感染的发生的概率非常小,但考虑到它的破坏性之大,不得不加倍慎重对待。
True or false, need longer time frame to make reasonable judgment. This is part of reasons EU is reluctant to allow more GMO crops planted there.
5、转基因大豆中存在未知DNA,可能带来新的不安全。人类对转基因大豆的研究很可能超出人类控制的范围,转基因大豆很可能发生人类没有预料到的变化,当然也可能给人类健康安全带来新的风险。
LOL, the whole genome of soybean is sequenced thus far. How does the author know there is an 未知DNA? All trasgene is a know gene which is introduced into elite varieties.
Of course, back to 5 - 10 years ago, government should have a better approach and policy to protect farmers and related industries. By the way, how many native and used-to-be dominant industry leaders have been JV or even bought out by foreign ones? |
