WASHINGTON - The news on aspartame was a little sweeter earlier this month, with one of the largest human studies so far finding no association with cancer.
Known by brand names such as NutraSweet and Equal, aspartame has been in and out of headlines since its approval in 1981, largely because of data raising the possibility of a link to brain cancer.
After years of relative quiet, the controversy revived in February, when a team of Italian researchers published disturbing data from an extensive animal study. The scientists, writing in the journal Environmental Health Perspectives, reported that rodents fed aspartame at levels under the daily acceptable limit appeared to have an increased risk of lymphoma, leukemia and brain cancers.
