We are advised by the Food Standards Agency (FSA), the non-ministerial Government Department with responsibility for food safety, that aspartame has been extensively tested and reviewed for safety by independent experts at national, European and international level and found to be safe at current levels of use.
The European Food Safety Authority (EFSA's) latest draft opinion, published for consultation in January, has confirmed this. Despite this, some people consider they react badly to consuming aspartame. Although not a safety study, the FSA commissioned a research study which looked at self-diagnosed individuals who consider they experience adverse effects after consuming aspartame. The results of the study will be subjected to peer review prior to publication later this year, as well as being shared with the EFSA for consideration as part of its current re-evaluation of aspartame.
