(2) 转基因食品来源于转基因生物体。转基因生物体自身发生了特定变化，基因工程技术使得其DNA发生这种变化成为可能。这些技术比突变（突变育种）精确的多，因为突变只使某个生物体暴露于辐射或化学物质从而创造一种非特异性而稳定的变化。人类改变食物机体的其他技术还包括选择性育种（植物育种和养殖动物），和体细胞无性系变异。
转基因食品于90年代初首次推出市场。通常情况下，转基因食品为转基因植物产品：大豆，玉米，油菜，棉花子油。但动物产品也已得到开发。2006年研究人员通过一种名为线虫的基因，在一头猪身上有争议的研发出ω- 3脂肪酸。研究人员还开发了一种转基因品种的猪，它能够更高效地吸收植物磷，因此其粪便的磷含量也减少高达60%。
批评家反对转基因食品的若干理由，包括理论或想象的安全问题，生态问题，经济问题，上述问题的提出是由于转基因生物体受知识产权法支配。

(11) The recession has hit middle-income and poor families hardest, widening the economic gap between the richest and poorest Americans as job layoffs ravaged household budgets.
(12) China's government declared two strains of genetically modified rice safe to produce and consume, taking a major step toward endorsing the use of biotechnology in the staple food crop of billions of people in Asia. China is the world's top producer and consumer of rice, so its use of modified varieties has the potential to alter the grain's global supply patterns. China's officials have been less constrained by public pressure over the sometimes-controversial use of biotechnology in food than officials in other countries. The government has long supported research into agricultural biotechnology as part of a drive to ensure the nation remains self-sufficient in staple crops.
