So apparently that Swedish study which claimed that many starchy foods, including things like bread, contain carcinogens was maybe a tad bit overstated. Perhaps the fact that the scientists announced their findings at a press conference before publishing them in a peer-reviewed journal might have been a tip-off as well.
The whole thing reminds me of a George Carlin joke: “Scientists have determined that saliva causes stomach cancer, but only when ingested in small quantities over a long period of time.”
