家园 看看昧国的转基因问答介绍的情况吧

昧国用于食用的转基因有多少?

以下是学者的回答

You might be surprised to know how few crops are actually available in the marketplace as GM varieties. Check out this response from Alan McHughen, biotechnology specialist and geneticist:

“Actually, only a few products in the produce aisle are GMOs—some sweet corn, some summer squash and some papayas.

事实上,只有少数产品是转基因的,譬如,一些甜玉米、一些西葫芦和一些木瓜

“There is currently a total of eight GM crops commercially available in the United States: corn, soybeans, cotton, canola, alfalfa, sugar beets, papaya and summer squash.

“Processed foods like sugar or vegetable oil may carry ingredients from GM crops, but the modified features of the crop are not present in the food and do not change the safety or nutritional values of the food.”

你可能会因为知道用来吃的转基因是这么少而感到惊奇

糖浆和菜油有不具有转基因特征

再看调查数据

78%的昧国家庭购买organic food

Despite a shaky economy, 78% of U.S. consumer are choosing to purchase organic foods, and 4 in 10 families are buying more organic products than they were year ago, according to findings from the "2009 U.S. Families' Organic Attitudes and Beliefs Study," jointly sponsored by the Organic Trade Association (OTA) and KIWI Magazine.

所以非转基因用于食用的比例很大一点都不值得奇怪。

以下是昧国农业部2012-09发布的昧国人均食品构成的表格

外链图片需谨慎,可能会被源头改

就那统计看,与转基因直接相关的食品仅是“玉米”和“沙拉”两项,合计只占食品总数的4.43%左右,即美国消费者吃到转基因食品的机会比率不到5%。若细看,那么,那机会比率就更是小得多多。譬如,

[1] 就玉米来说,美国官方统计,当年的玉米总产:313,950,000吨,其中非转基因种植面积比例为12%,如此,非转玉米产量为37,674,000吨,用它满足美国食品玉米的市场需要是绰绰有余的。

如果该图片很多人看不到的话,可以直接到USDA官网看数据

点击data set 的 table 5,可以看到昧国人年均消费玉米是28.7磅。
