Aspartame , msg, and some others are excitotoxins. That means they cause the brain cells to be stimulated to a point of over-stimulation that results in cell damage or cell death. Caffeine also stimulates the brain cells. Its worst problem is it effect on the adrenal system. PCS often leaves the adrenal system compromised so any additional stress to it is counter-productive.

Caffeine to a PCS person is like caffeine for a drunk. You just end up wide awake. My doctor read me the riot act when I told him I was using caffeine to overcome my drowsiness. Actually, two doctors told me this.

Aspartame has three components. Aspartic acid, phenylalanine, and methyl ester. The aspartic acid is a neurotransmitter that effects norepinephrine. Phenylalanine is a neurotransmitter that effects serotonin to the opposite of the norepinephrine. This creates a bad situation for brain cells that are struggling to function properly.

The methyl ester converts to methyl alcohol, a toxic substance that the body does not have a system to eliminate. GD Searle tries to down play these problems by mis-stating the science. Aspartame is being slowly removed from the market and replaced by Sucralose, a different toxin.

Aspartame is still used in may low calorie foods. Its worst use is in foods that get heated, whether purposely or just by sitting in a warm location. 100 degrees is enough to cause the aspartame to break down into dangerous components.

Remember this simple fact, aspartame is a neurotoxin that can cross the blood brain barrier. Sucralose is an organic chlorine toxin that is toxic to the rest of the body. The body can handle most ionic chlorine like in salt. It has no way of tolerating organic chlorine. A google or bing for organic chlorine will be an eye opener.

A simple concept to remember is this. Our FDA is the best government agency money can buy. ALL of the people who were part of approving aspartame at the FDA were later hired by the soft drink and aspartame industry. You can thank Donald Rumsfeld for the problems, deaths included, that aspartame has caused. He headed up GD Searle during the aspartame approval process.
