Synopsis
One of the simpler food myths, it is said that the "candy coating" on M&Ms is made up of dyed cockroach shell, possibly due to the fact that Mars, Inc., which manufactures the candies, does not release the secret recipe for them. As such, this cannot be 100% disproven without extensive forensics research, but needless to say it probably wouldn't have gotten past the FDA if it actually contained cockroach.
