After eating the nachos at the Mexican restaurant at Epcot (Disney World) my entire family had green stools. The "magic" shouldn't extent to the food. Many children are eating these multi colored nachos. In order for large adults stools to turn that bright green the amount of food coloring Disney must be using has to be beyond what is recommended. Also this problem is not new. When I started googling what would possibly turn stools so bright green. I discovered that it would have been the blue food dye. Real blue corn is available and there is no need to color the nachos blue.
