Talk:Ponceau 4R

From Wikipedia, the free encyclopedia

[edit] Ponceau 4R as a carcinogen

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.

[edit] New UK government report shows link to hyperactivity in childern

Take a look at these two articles in the newspaper The Daily Telegraph. Would be nice to have them integrated in the article. [7] [8] MaxPont 21:02, 10 May 2007 (UTC)

[edit] This article needs cleanup

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)
