The U.K. Food Standards Agency (FSA) has announced the final results of an aspartame study commissioned by the Committee on Toxicity of Chemicals in Food, Consumer Products and the Environment (COT), which peer-reviewed the initial findings in December 2013. Authored by Hull York Medical School researchers, the study relied on data from 48 individuals who self-identified as sensitive to the artificial sweetener aspartame.

After examining various factors—including psychological testing, clinical observation and biochemistry, and metabolomics—the authors found that the participants “showed no difference in their responses after consuming a cereal bar, whether it contained aspartame or not,” according to FSA’s March 19, 2015, press release. Additional details about COT’s review of the study data appear in Issue 506 of this Update.
