Are there any conclusive studies that suggest that aspartame is dangerous?

The Aspartame Danger. In the body, aspartame has been shown to reduce production of the powerful anti-oxidant glutathione in the brain, thus leaving the brain vulnerable to oxidative stress and neurodegenerative diseases (http://www.Ncbi.Nlm.Nih.Gov/pubmed/22385158). A study conducted in nyc recently found that regular consumption of diet drinks with aspartame increased the risk of heart attacks significantly.
Aspartame. 92 different health problems have been reported with asapartame. It has lead to problems like seizures and triggering of migraine headaches.
