After conducting "one of the most comprehensive risk assessments of aspartame ever undertaken", the European Food Safety Authority has released its verdict on 10 December 2013.
The agency came to the conclusion that aspartame and its breakdown products are "safe for human consumption at current levels of exposure".
The EFSA press release says that this was an important step forward in"strengthening consumer confidence in the scientific underpinning of the EU food safety system and the regulation of food additives".
However, professor of Science Policy Erik Millstone says:
"The EFSA Panel opportunistically accepted at face value most of the studies that suggested that aspartame is harmless, while entirely discounting every single study that suggested aspartame may be harmful, even though the quality, power and sensitivity of many of the studies that were discounted were markedly superior to those of the contrary studies deemed reliable."
