Blue Rats and M&Ms

08/12/2009

Blue.rat.after.urmc We all know that albino animals have pink eyes and skin.  So why is this albino lab rat blue? 

Medical researchers have discovered that the blue dye used in food products such as M&Ms, Jell-O and Gatorade can actually help heal spinal injuries.  Injured rats regained the ability to walk after receiving an injection of the dye.  The side effect, of course, is that the rodents themselves turned blue.

Apparently, Americans eat over 100 million lbs. of this blue dye every year. Luckily, it seems the dye has to be injected in order to turn skin blue.
