Research reveals that synthetic sweeteners, often used as sugar substitutes, might accelerate brain aging.

In a groundbreaking study, researchers have found a potential link between the consumption of artificial sweeteners and faster cognitive decline in adults. The study, published in the American Academy of Neurology's medical journal, followed nearly 13,000 adults in Brazil over an average of eight years, conducting tests on their memory, language, and thinking skills at the start, middle, and end of the study.

The findings suggest that people who consume high amounts of artificial sweeteners commonly found in low-calorie drinks and desserts experience cognitive decline 62% faster than those who consume the least. The decline in cognitive skills was roughly equivalent to 1.6 years of aging.

The study focused on artificial sweeteners such as aspartame, saccharin, acesulfame-K, erythritol, xylitol, sorbitol, and tagatose. People with diabetes were more likely to use artificial sweeteners as sugar substitutes, and the association between cognitive decline and artificial sweetener consumption was stronger in participants with diabetes than in those without.

However, the study did not find a link between cognitive decline and tagatose consumption. The European Food Safety Authority (EFSA) is currently re-evaluating the safety of all sweeteners permitted for use in foods before January 2009.

Leading European companies producing products containing the artificial sweetener Aspartame include multinational firms such as Tate & Lyle Plc, Cargill Incorporated, ADM, Ingredion Incorporated, Roquette Freres, and DuPont, which supply ingredients for various beverages, baked goods, confectionery, processed foods, and pharmaceuticals within Europe.

Claudia Kimie Suemoto, associate professor in the discipline of geriatrics at the University of São Paulo, stated that the findings suggest certain sweeteners may have negative effects on brain health over time. The study's conclusions are in line with discussions about the potential negative effects of artificial sugars in the scientific and medical communities.

Despite the concerns, it is important to note that low- and no-calorie sweeteners are often seen as a healthy alternative to sugar. However, the study's findings highlight the need for further research into the long-term effects of artificial sweeteners on health.

The study relied on diet information reported by the participants and exclusively analyzed some non-sugar sweeteners. No association between brain health decline and sweetener consumption was observed in participants over the age of 60.

In the European Union, alternatives to sugar undergo a safety evaluation before their commercialization in the common market, and their use must be indicated on the label of a food or drink. As the research continues, it is crucial for consumers to be aware of the potential implications of their dietary choices and to make informed decisions about their health.
