DBennet "The link you posted is the same data.
Packaged in a different and less relevent journal.
A typical tactic in getting less impressive but media friendly research coverage."
This was the second report from the Ramazzini Foundation. This report was published in 2007 and the first was published in 2005. It is not the same data as you say.
In the Ramazzini Foundation's second study Life-Span Exposure to Low Doses of Aspartame Beginning during Prenatal Life Increases Cancer Effects in Rats, the conclusion was:
"The results of this carcinogenicity bioassay confirm and reinforce the first experimental demonstration of APM?s (Aspartame's) multipotential carcinogenicity at a dose level close to the acceptable daily intake for humans. Furthermore, the study demonstrates that when life-span exposure to APM begins during fetal life, its carcinogenic effects are increased."
It was published on the National Center for Biotechnology Information so not sure why you state "A typical tactic in getting less impressive but media friendly research coverage."
DBennet : "It does not change the consensus of the experts that the data was flawed.
Or detract from the fact that it flies in the face of the bulk of the literature, which includes larger better studies, from higher up the evidence pyramid that are on humans not a rat model."
Not sure why you keep discrediting studies on rats. In the conclusion of the Ramazzini Foundation first report: "The results of carcinogenicity bioassays in rodents are consistent predictors of human cancer risks (Huff 1999; Rall 1995; Tomatis et al. 1989)."
12 U.S. environmental health experts found the second study to be so important that they wrote to the FDA in June 2007:
They agreed that "chronic animal feeding studies are accepted widely as valid predictors of likely carcinogenic risks for humans: importantly, all acknowledged human carcinogens when tested adequately in animals are also carcinogenic, and many known human carcinogens were first discovered in animals."
Regarding dosing they wrote:
"To put the doses used in the study in context, consider that the Acceptable Daily Intake of aspartame in the United States is 50 mg/kg. The 20 mg/kg dose is equivalent to a 50-pound child?s drinking about 2½ cans of soda per day and a 150-pound adult?s drinking about 7½ cans of soda per day...The lower dose is something that about 5 percent of American teenagers actually consume.Obviously, few people drink the larger amounts of aspartame-sweetened soda, but one must presume that lower levels of consumption would lead to increased, but proportionately lower, cancer risks."
The letter from the 12 U.S. environmental health experts concludes: "Considering how widely aspartame in consumed by young children, as well as adults, in the United States and abroad, it is essential that this review be done as expeditiously as possible. If that review confirms that aspartame caused cancer in the laboratory animals, the FDA must invoke the ?Delaney amendment? and revoke its approval for the artificial sweetener."
