My theory is when you start on iodine, your on a journey of listening to what your body actually wants, I have been craving healthy foods and rejecting Sugar and refined carbs. The thought of eating anything sugary makes me feel physically ill.
My body doesn't want it, and is letting me know this in no uncertain terms. In the western world today we are taught to ignore our intuition and to doubt our own ability to heal ourselves. When we abdicate our personal responsibility for our health, we are then at the mercy of the sickness industry.
