The artificial sweetener sucralose (sold under the brand name Splenda) could potentially pose health risks, so it needs to be better understood before the sweetener should be assumed to be safe, one advocacy organization says.
The Center for Science in the Public Interest, a nonprofit watchdog group, said today that it was downgrading its safety rating of sucralose from "safe" to "caution," meaning that the additive "may pose a risk and needs to be better tested."
The change was spurred by a recent study from researchers in Italy that found that sucralose caused leukemia in mice, according to the CSPI. This study has not been published, and needs to be reviewed by other scientists to determine whether the findings are credible.
While sucralose may turn out to be safer than other artificial sweeteners, "the forthcoming Italian study warrants careful scrutiny before we can be confident that the sweetener is safe for use in food,” said CSPI executive director Michael F. Jacobson.
