thread_title:  Ponceau 4R in everyday items 

message: This is a fairly controversial claim, and as such, "Ponceau 4R has been proven to cause cancer" isn't good enough. Proven by whom? And when? Cites are required.
I had a look around on PubMed, but it wasn't particularly helpful. Is the chemical teratogenic? Genotoxic? Carcinogenic? No. Yes. Maybe. 
Various studies:

thread_title: New UK government report shows link to hyperactivity in childern 

message: This article makes many claims without citation, and most of
the citations that are provided are just newspaper articles.
As usual, the newspaper articles are not clear proofs of anything.
In some cases, even when there is a citation, the citation actually makes no mention
of the claim that is supposedly being proven.
This article needs some serious cleanup. Unfortunately, that will be very difficult.
There are many people who are very emotional about the issue of food
colorings. They will likely wreck any good cleanup work that is done
here, unless Wikipedia standards are somehow enforced here.  —Preceding unsigned comment added by Ygale (talk • contribs) 10:39, 19 November 2007 (UTC)
