MSG is an aritificial substance known to cause problems in all sorts of ways. stay away. Dr. Amen, whom I respect for his work, uses imaging to have an objective test to make a diagnosis, which doctors have subjectively diagnosed for decades without imaging. MR scans cost 2K in the US and metabolic scans 4+k. it's novel work, but I don't see the need for it in medicine. just my 2cents.
