My daughter has been exhibiting rage and headbanging that has has progressed over the last 9 months with many other symptoms . After I dsicovered your website I eliminated annatto a week ago and the headbanging diminished but has not disappeared. Annatto was in her vitamins and granola bars that she consumed daily. It was also in many other items that she consumed such as ice cream, Doritos, salad dressing.  I am now eliminating all additives you recommend to avoid. - USA
