Also from the article:"By lucky accident, researchers discovered that the commonly used food additive FD&C blue dye No. 1 is remarkably similar to a lab compound that blocks a key step in nerve inflammation.

And researchers reported only one adverse effect: The rats turned blue." - Hanna Wiszniewska
