Has anyone see ADHD symptoms disappear since you eliminate allergenic foods?
know of several families who have tremendous improvement and some that did disappear altogether -
what plentifully of them did was thieve out all processed food and go back to essential cooking for a while to clear out the system - look for a naturopath in your nouns that specializes with such cases
Sort of - our son be diagnosed with ADD years ago by a exceptionally good pediatrician. A few of his teacher's insisted that he have ADHD, but we were competent to prove (at least to ourselves and to the doctor) that foods be adding the "H" to his practice (in particular food dyes - reds, blues, purples, and some sugars - ketchup turns out to be a bottle full of both sugar and food dye!).
With the hyper cut gone, and once we found the right dosage of the right medication, the ADD was capably under control and our son be 'allowed' to be himself again!
