Controversial study suggests that GM foods lead to tumors in rats

A controversial French study contends that a diet high in genetically modified corn leads to the growth of tumors — at least in the researchers' rats, who suffered mammary tumors as well as kidney and liver damage. The rats were fed a variety of Monsanto corn engineered to tolerate "dousings" of the weed-killer Roundup. Photos of the rats laboring under the tumors are shocking, but some scientists argue against the study's findings, saying that the pesticide, rather than the corn modified to withstand pesticide, was to blame. Some opponents said that too few rats were involved in the research, while another asked why similar findings hadn't been observed in the U.S., where "'GM has been in the food chain for over a decade." Feel better about that? [Source]
