Hello everyone,
My 2-yr old son is B-thal minor. We are considering changing cooking pans in our home. From my research, cast iron is a very good choice. Specially from the perspective of low toxicity. But cast iron can leach some iron into our foods. 
How much of that is a concern for Thal minors ? I've heard that good quality enameled pans (for eg: Le Creuset) might not leach iron. But I still want to be sure.
His iron test back in April 2013 has following results:
  Ferritin  8  (Normal range: 7-150)
  Iron, Serum         99  (Normal range: 20-158)
  Unsaturated IBC  320 (Normal range: 155-300)
  Calculated Total IBC 419 (Normal range: 250-450)
  Calculated % Iron Sat  24 (Normal range: 20-50)
Thanks!
