What is MSG?
MSG is glutamate, the savoury taste in tomatoes and parmesan, with a little sodium. A Japanese chemist found it in seaweed broth in 1908. It has about a third of table salt's sodium. And "Chinese restaurant syndrome"? Blinded studies found no consistent reaction to MSG eaten with food. So far, regulators call it safe in normal amounts. Next: What is gaslighting?
