Does Burnt Toast Cause Cancer? Maybe
Over on The Atlantic Food Channel, food policy writer Marion Nestle discusses the dangers of charred toast. Canada recently added acrylamide, the carcinogen that forms on burnt toast, to its list of toxic substances and the European Union is calling it a hazardous chemical "of high concern." But then you have Dutch reports saying there are no real links between acrylamide and cancer.
So maybe burnt toast isn't as bad as swallowing a cigarette but just to be safe, you should probably aim for golden to golden-brown on the toast color spectrum.
