MEP Krzysztof Brejza (PPE) has asked the European Commission to reassess the safety of low- and no-calorie sweeteners in light of recent studies linking them to cognitive decline and cerebrovascular damage. In a written parliamentary question submitted on 22 April 2026, Brejza highlighted a 2025 prospective study in Neurology involving 12,772 participants that found higher sweetener consumption associated with faster memory and verbal fluency decline, especially in people under 60. He also cited experimental evidence on erythritol suggesting mechanisms such as oxidative stress and endothelial dysfunction in brain microvascular cells.
an assessment of how the new findings relate to existing EFSA evaluations, a request for an updated risk assessment focusing on long-term cognitive and neurological effects, and consideration of additional risk communication or labelling measures, particularly for vulnerable groups. The MEP frames his request as a precautionary, science-based approach to public health, while acknowledging that EFSA currently considers authorised sweeteners safe within acceptable daily intake levels.
Policy orientation and ambition The question signals a push for tighter regulation of artificial sweeteners, potentially leading to stricter acceptable daily intakes, new labelling requirements, or even re-evaluation of certain substances. Brejza's reference to "vulnerable groups" suggests he may seek targeted warnings for children, pregnant women, or older adults. The emphasis on long-term neurological effects, rather than acute toxicity, indicates a desire to broaden the scope of EFSA's risk assessments beyond traditional endpoints.
Expected follow-up The Commission typically has six weeks to reply to written parliamentary questions. Its answer will reveal whether it shares Brejza's concerns or maintains that current evidence does not warrant a reassessment. A positive response could lead to a formal mandate for EFSA to update its opinion, while a dismissive reply may prompt further parliamentary pressure or a resolution.
