I probably don't have to do much to convince you to stay away from moldy bread, but if you did somehow get into the habit of being "OK" with eating that spotty, green and white bagel, there are some pretty scary effects.

Digg consulted with Professor of microbiology Randy Worobo, and he said that there are different types of mold that can latch on to your bread, and unless you're a microbiologist, you can't really tell which type is on your bread.

In some instances, the mold could be toxic enough to screw up your respiratory system. There is a house mold called stachybotrys that can stick to your bread, and if you ingest enough of it, your mouth, throat and nose can get irritated and can even make you go into shock.

Even sniffing the mold can lead you to inhale mold spores and screw up your respiratory system, according to NY Times.

Another terrible occurrence, if you decided to eat moldy bread on a regular basis, is cancer. There are certain molds that create mycotoxins which carry cancer-causing carcinogens. But don't get too scared because that's one of the least likely scenarios.

Those are the absolute worst-case scenarios, though, and  Professor Worobo said that most of the time, the "risks are minimal."

While you're probably fine if you accidentally eat some moldy bread, keep an eye on it, and throw it the hell out if it looks remotely sketchy.
