Aspartame 'linked' to leukaemias

Dr Morando Soffritti and colleagues at the Cancer Research Centre in Bologna fed eight-week-old rats varying concentrations of aspartame.
Compared with control rats given no sweetener, many of the female rats in the experiment developed lymphomas or leukaemias - the risk increasing with the dose of aspartame.
The researchers say their study raises concerns about the levels of aspartame to which humans can be exposed and, therefore, "urgent re-examination" of aspartame's safety is needed, "especially to protect children".
