Gluten allergy can lead to devastating symptoms, which often end up being treated with very toxic drugs, even in children.  Writer Susannah Meadows writes in the 2/1/13 Sunday Times Magazine about a 3 year old boy who was unable to run or play due to joint pain, while his twin brother was fine.  He was diagnosed with Juvenile Idiopathic Arthritis (which simply means, despite the long name, arthritis of unknown causein a child of).  She went the traditional route of non steroidal anti-inflammatory pills until a much stronger drug, Methotrexate, was put on the table.  The child’s mom, at that point, decided to take matters into her own hands and go in a different direction.  She found a Functional Medicine practitioner who found the cause of the arthritis, gluten sensitivity.  A gluten free diet and natural anti-inflammatory substances eventually cured the child.
