this is a pretty good video even though its pretty old but its still got a lot of good info, i've always been anti aspartame and people always tell me i'm being anal about healthy eating.. 100% of industry related studies claiming aspartame to be safe, and 100% of independent studies flagging some sort of health concern raises some eyebrows but commercial advertising is more powerful than a handful of independent studies.

Conclusion/Findings: Excitotoxins, as used in foods today, may produce blood elevations high enough to cause damage to the nervous system of young children, damage which is not detectable at the time of occurrence but which may give rise to subtle disturbances in neuroendocrine function in adolescence and/or adulthood.

Conclusion/Findings: Shows that aspartate has a role in causing mental retardation, but the mechanism by which it does that is still unknown.

Conclusion/Findings: Identified some case reports in which the symptoms may be attributable to aspartame in commonly-consumed amounts. Headache, mood alterations (anxiety, agitation, irritability, or depression), insomnia, dizziness, and fatigue were the most frequently reported symptoms, with one case of a child in a double-blind test who became hyperactive after consuming products with aspartame.

Conclusion/Findings: Found that individuals with mood disorders are particularly sensitive to this artificial sweetener and its use in this population should be discouraged. In the clinical study, the project was halted by the Institutional Review Board after a total of 13 individuals had completed the study because of the severity of reactions within the group of patients with a history of depression

Funded By: Clinical Research Laboratory, Denmark
Conclusion/Findings: The study showed that the intake of aspartame in a not unrealistically high dose produced a marked and persistent increase of the availability of Phe to the brain, which was not observed after protein intake. The study indicated, furthermore, that Phe was cleared faster from the plasma after consumption of protein compared with aspartame.
