家园 应该是"美国人被爱吃转基因"。

根据《食品公司》和这篇文章的说法, 是美国食品和药物管理局(FDA)不愿意强制要求贴标签注明食品含有转基因成分:

The FDA contends that GM foods are substantially equivalent to non-GM foods, and therefore not subject to more stringent labeling.

而美国超市里整株的转基因水果和植物是很少的(there are very, very few genetically-modified whole fruits and vegetables available on produce stands)。但是由于各种精制食品,例如菜油和早餐谷物类,以及由大豆衍生出来的各种食品添加剂,都含有转基因成分,尽管这些成分都很少(some tiny percentage of genetically-modified ingredients),但由于它们的广泛使用,还是使得几乎所有的美国消费者都食用过转基因食品(all U.S. consumers have been exposed to GM food products)。

这里有两个重要的区别:

1)这是美国人民无奈接受的,并非是他们“爱吃”。而是由于FDA的不作为,美国人民无法知道食品中是否含转基因。所以说成是“美国人被爱吃转基因”还差不多。

2)美国人也不是整个地吃转基因食品,而只是食用了极其少量(tiny percentage)的转基因制成品。

所以谁要说“我在美国吃了十几年的转基因食品”那是误导人。砒霜每天吃一点点短时间是没事的。如果当饭吃,肯定叫他当场挂掉。

我不知道方舟子是否说过类似的话。如果说过,那是非常误导人、不负责的说法,不是一个科学工作者在公众场合说话的方式。谁要这么说,谁去把转基因玉米当主食吃上几年再说。

我不是反对转基因,我是反对这种误导。

How prevalent are GM crops? What plants are involved?

According to the FDA and the United States Department of Agriculture (USDA), there are over 40 plant varieties that have completed all of the federal requirements for commercialization (http://vm.cfsan.fda.gov/%7Elrd/biocon). Some examples of these plants include tomatoes and cantalopes that have modified ripening characteristics, soybeans and sugarbeets that are resistant to herbicides, and corn and cotton plants with increased resistance to insect pests. Not all these products are available in supermarkets yet; however, the prevalence of GM foods in U.S. grocery stores is more widespread than is commonly thought. While there are very, very few genetically-modified whole fruits and vegetables available on produce stands, highly processed foods, such as vegetable oils or breakfast cereals, most likely contain some tiny percentage of genetically-modified ingredients because the raw ingredients have been pooled into one processing stream from many different sources. Also, the ubiquity of soybean derivatives as food additives in the modern American diet virtually ensures that all U.S. consumers have been exposed to GM food products.
