Dreena, My daughter’s ADD stopped when she quit gluten. I discovered she is Celiac. One symptoms of Celiac is “brain fog”. Wheat has been genetically engineered to have more protein thus more gluten as the protein is in the gluten. If the scientists had left it alone; more people could probably tolerate it better. Gluten-free products fill the grocery shelves now. She was at the point of collapse as it caused her to be so ill. The disease had really progressed and damaged her colon so nutrients could not be absorbed. Doctors do not readily diagnose it. She was told that she had lingering flu by a top US hospital. I don’t know if all ADD is caused by gluten. I wonder if there are other foods linked to ADD.
