Can I suggest you read Excitotoxins, the Taste that Kills by Dr. Blaylock, a neurosurgeon. MSG and Aspartame both kill brain cells. In his book he says that magnesium will protect you from the effects of MSG and aspartame (magnesium is found in green vegetables).
Another good author is Dr. Norman Walker who has some good books on juicing. He lived to about 109. Juicing is the fastest way to get nutrients back into the body. He also says that tap water is bad for us because it contains non organic minerals, again that the body cannot assimilate. We should all be drinking distilled water.
