"We are trying to go petroleum free. For now we have discovered all the kids are lactose intolerant. And that red dye SERIOUSLY affects my daughters behaviours. Her Grandma snuck her some candy that had that darn red dye. That was yesterday at lunch. Today she is still very agitated and aggresive and keeps having what we call "freak outs." Could a chemical or dye still be causing a problem after that long or could it be something else? Thank you for your help."
Oh yes, dear reader, a reaction can easily last for 3 days or longer. This is especially true when you're talking about red dye or other colors. And, when you add the lactose intolerance or other intestinal issues you compound the reaction times. If the intestines are working slowly they aren't removing the problem (dye) effectively.
As for the lactose intolerance, have you tried raw milk yet? My kids and are are terribly lactose intolerant but we can drink raw milk just fine. We do much better on raw milk than any milk substitute. To find a store in your area look here http://www.realmilk.com/
