The current method of raw food production is largely a response to the growth of the fast food industry since the 1950s. The production of food overall has more drastically changed since that time than the several thousand years prior. Controlled primarily by a handful of multinational corporations, the global food production business - with an emphasis on the business - has as its unwritten goals production of large quantities of food at low direct inputs (most often subsidized) resulting in enormous profits, which in turn results in greater control of the global supply of food sources within these few companies. Health and safety (of the food itself, of the animals produced themselves, of the workers on the assembly lines, and of the consumers actually eating the food) are often overlooked by the companies, and are often overlooked by government in an effort to provide cheap food regardless of these negative consequences. 目前的生食生产方法在很大程度上是对20世纪50年代以来快餐业增长的回应。自那时以来，食品生产的总体变化比几千年前更为剧烈。主要由少数几家跨国公司控制的全球食品生产业务——重点是该业务——将以低直接投入（通常是补贴）生产大量食品作为其不成文的目标，从而带来巨大的利润，这反过来导致对这几家公司内全球食品供应的更大控制。健康和安全（食品本身、自己生产的动物、流水线上的工人以及实际食用食品的消费者的健康和安全）常常被公司忽视，而政府为了提供廉价食品而忽视了这些负面后果。
