Aspartame's Effects on the Brain

In the last eight or nine years which is about three to five years after aspartame was approved there's been a striking increase in the incidence of malignant brain tumors. Dr john only does not say flat out that aspartame is responsible for the rise in brain tumors but he does believe that his analysis of the data shows that it's the most likely suspect. He says many researchers have discounted other environmental factors and only says the same types of aggressive brain tumors that showed up in the aspartame animal studies over 20 years ago are now increasing in the human population.
