i have a friend who has two kids with a food-dye allergy (their reaction is lose all emotional control and bladder control). They used to spend a lot of time at my house, and I started reading all labels for food dye.
It is, in fact, in EVERYTHING.
My friend had a long-standing theory that a huge number of children with behavioral issues were suffering from the same sensitivities as her son. Until they eliminated food dyes, he was OUT OF CONTROL. He was being tested for autism, ADD, ADHD and everything else you can think of. One doc told them to eliminate dye....... 3 days later he was a different child.
I hope the studies continue, and the availability of foods without dye increases.
There's always a reason to bake.
