转基因食品也同样具有两面性。转基因食品进入人体以后, 可能对 人体健康产生危害。首先,大多数转 基因食品中引入的外源蛋白质 进入人体以后可能产生新的过敏物质, 引起人体的过敏反应。1996 年美国先锋种子公司将巴西坚果某基因转入大豆中, 结果对巴西坚 果过敏的人群也对该大豆过敏, 该大豆种子最终没有被批准商业化

转基因食品发 展的现状
近十余年来，现代生物技术的发展在农业上显示 出强大的潜力，并逐步发展成为能够产生巨大社 会效益和经济利益的产业。1999年，全世界有12 个国家种植了转基因植物，面积已达3990万公顷。 其中美国是种植大户，占全球种植面积的72%。 世界很多国家纷纷将现代生物技术列为国家优先 发展的重点领域，投入大量的人力、物力和财力 扶持生物技术的发展。但是，转基因食品在世界 各个国家和地区之间的发展是不均衡的。近年来， 我国现代生物技术的研究开发已经取得了很多成 果。我国的转基因食品技术仅次于美国与加拿大。 欧洲国家的转基因食品技术并不是非常的发达， 这是因为他们明白转基因食品危害十分大，并通 过立法来达到防止转基
转基因食品_PPT
过敏反应
• 对于一种食物过敏的 人有时还会对一种以前他 们不过敏的食物产生过敏， 比 转基因食品—存在隐 患 • 如：科学家将玉米的某一 段基因加入到核桃、小麦 和贝类动物的基因中，蛋 白质也随基因加了进去， 那么，以前吃玉米过敏的 人就可能对这些核桃、小 麦和贝类食品过敏
对抗生素的抵抗
• 当科学家把一个 外来基因加入到植物 或细菌中去，这个基 因会与别的基因连接 在一起。人们在服用 了这种改良食物后， 食物会在人体内将抗 药性基因传给致病的 细菌，使人体产生抗 药性。 目录
• 转基因食品也有缺点： 所谓的增产是不受环 境影响的情况下得出 的，如果遇到雨雪的 自然灾害，也有可能 减产更厉害。且多项 研究表明，转基因食 品对哺乳动物的免疫 功能有损害。更有研 究表明，试验用仓鼠 食用了转基因食品后， 到其第三代，就绝种 了。
毒性问题
• 一些研究学者认 为，对于基因的人工 提炼和添加，可能在 达到某些人们想达到 的效果的同时，也增 加和积聚了食物中原 有的微量毒素。
• 回到正题
• 其实，转基因的基本原理也不难了解，它与常规 杂交育种有相似之处。杂交是将整条的基因链 （染色体）转移，而转基因是选取最有用的一小 段基因转移。因此，转基因比杂交具有更高的选 择性。
• 目录
• 也就是说，通过基因 工程手段将一种或几 种外源性基因转移至 某种生物体（动、植 物和微生物），并使 其具有效表达出相应 的产物（多肽或蛋白 质），这样的生物体 作为食品或以其为原 料加工生产的食品。
• 对于孟山都公司，个人表示极其的不满。刚才我有讲到， 孟山都公司是转基因食品中最大的公司。然而他所销售的 产品却大多流向中国、印度等人口数量大，食品无法自给 自足的国家。使得赚取高额利润与压制国家发展。反而对 本国或发达国家却禁止使用转基因食品。 • “控制了资源，就控制了世界，但控制了食物，就控制了 人类” • 孟山都公司的这种做法，我无法得知他的用意何在，结果 一定是不好的，至于他们是不是想控制人类，那就你们自 己yy吧。

Improve nutritional value
GM technologies can be used to create crops with higher levels of essential nutrients such as vitamins and minerals
Address food security
Spread of modified genes
The spread of modified genes from GM crops to wild relatives can disrupt natural ecosystems and lead to the creation of "superweds" that are resistant to heroics
Creation of New Crops
Genetic modification has enabled the creation of new types of crops that may not be possible through traditional breeding methods
This can significantly lower the amount of pests applied to crops, reducing environmental pollution and potential health risks associated with these chemicals
Limited transparency
The production and distribution of GM food often lake transparency, making it difficult to trace their origin and assess their safety
