当然我现在不会回答终极问题,也就是转基因到底合不合适的问题,单我可以稍微解答下转基因食物的消化吸收问题

Hypothetical Link between Infertility and Genetically Modified Food.

Abstract
It is speculated that genetically modified food (GMF)/genetically modified organism (GMO) is responsible for infertility development. The risk associated with a wide use of GMFs/GMOs provides the basis for social criticism. However, to date, it has not been clarified whether the harmful effects is directly resulted from products of genetic modifications or from the transgenesis process. Extensive experience with the risk assessment of whole foods has been applied recently on the safety and nutritional testing of GMFs/GMOs. Investigations including sub-acute, chronic, reproductive, multi-generation and carcinogenicity studies have tested the safety of GMFs. We extrapolated the potential risks associated with GMFs/GMOs on reproduction, and analyzed the multi-aspect linked between infertility and GMFs/GMOs. It could be conjectured that GMFs/GMOs could exist potential hazard on reproduction, linking to the development of infertility through influencing the endocrine metabolism, endometriosis. However, little evidence shows the impaction on embryo or reproductive related tumor due to the limited literatures, and needs further research. The article presents some related patents on GMFs/GMOs, and some methods for tracking GMOs.

楼主个人观点
1 一般食物或者转基因食物DNA碎片甚至全基因组可以进入人体组织,但不是细胞内;植物细胞的内的miRNA(一种DNA的转录产物)在动物模型被证实能整合进宿主的DNA参与调控,虽然目前并没有直接证据DNA整合进宿主并且不良反应的发生,但是我个人不相信短期改造的基因如自然选择的基因那么温和。至少大家不要认为小肠里能把各种DNA消化或者去除干净
2 短期的基因改造除了对自身的影响,也强迫环境加速改变,比如抗病虫害基因,死掉一批吃不了庄家的害虫,那种少数变异存活下来的害虫会更加强大,这就好像抗生素从最开始的青霉素很灵验到现在基本都耐受一样,以此类推,基因改造除了对产量 形态 植物个性的改造外,受伤害的一方会引起何种反弹也是值得考虑的事情
3 当然就好像原子能,你可以做成核电厂 也可以做成原子弹,如果有正负面效应影响更加深广的东西出来,我们是寄希望科学家们和官员们的操守还是伦理道德?
