The U.K. Committee on Toxicity of Chemicals in Food, Consumer Products  and the Environment (COT) has released a December 2013 position paper on the purported health effects of aspartame, which is currently being reviewed by the European Food Safety Authority as part of its re-evaluation of all food additives. Commissioned by the U.K. Food Standards Agency (FSA), the paper apparently analyzes a double-blind randomized crossover study conducted by University of Hull York Medical School researchers, who asked 50 participants with self-diagnosed adverse reactions to aspartame to consume a snack bar without knowing whether it contained the substance in question.

Based on the study’s findings, which compared the responses of these partici- pants to a control group, COT has concluded that “the results presented did  not indicate any need for action to protect the health of public.”The committee will release the full minutes of its discussion once the study has been accepted for publication into a peer-reviewed scientific journal.
