In a written answer on 3 July 2026, Commissioner Várhelyi, on behalf of the European Commission, rejected calls for an updated risk assessment on the long-term neurological effects of artificial sweeteners, arguing that the existing EU safety and labelling framework is sufficient. The response, addressed to MEP Krzysztof Brejza (PPE), who had cited a 2025 prospective study linking sweeteners to cognitive decline and emerging evidence on erythritol's cerebrovascular effects, reaffirms the Commission's reliance on EFSA's evaluations. Várhelyi noted that observational studies, while suggestive, do not demonstrate causality and are weighed within EFSA's broader evidence approach.
The answer contains no concrete proposals for new risk communication or labelling measures, instead pointing to existing rules that require sweeteners to be listed in ingredients and polyols to carry laxative-effect warnings. The Commission's stance signals a preference for maintaining the current regulatory status quo, prioritising business predictability over precautionary action.
Stakeholders impacted include consumers, particularly those concerned about cognitive health, who may seek clearer labelling; the food and beverage industry, which avoids new compliance costs; public health advocates, who may push for further research; and EFSA, whose existing assessments remain unchallenged. The answer is a declarative defence of the current system, scoring low on policy substance with no new measures announced.
