Is it normal that blue food coloring does this to me?
I don't eat a lot of blue food coloring, but whenever I do, I have green bowel movements. It doesn't even have to be a ton of food coloring for this to happen. I can have a dish of blue ice cream, or a blue slushy, or even Crunchberries, and everything comes out green. It isn't even slightly green, it's a really bright green. Does this happen to anyone else?
