牙膏是我們每個人每天都會使用的東西,但是,英國每日郵報的一篇報道說,高露潔牙膏含有一種化學物質和癌細胞增長有著聯系.

The Daily Mail: It has emerged a chemical that has been linked to cancer cell growth is being used by millions of Americans in toothpaste every day.

The company behind Colgate Total insists that triclosan, which it uses to stave off gum disease, is safe to use because the toothpaste was approved in 1997 by the Food and Drug Administration.

But the toxicology documents used by the FDA to approve the toothpaste were only released early this year after a Freedom of Information Act lawsuit last year - and reveal the agency relied upon company-backed science to reach its conclusion.
