Dr. Gérald Kierzek, an emergency physician and medical director of Doctissimo, suggests that people should gradually reduce their sugar intake in coffee rather than replacing it with artificial sweeteners like xylitol. He cautions against the possible health risks that may be linked to these alternatives. In a commentary on ICI's Les conseils du Docteur Kierzek, Dr. Kierzek emphasizes that it is better to slowly adjust to a less sweet taste than to rely on a quick fix. He explains that xylitol is a type of polyol, also known as a sugar alcohol, which is commonly used as a sugar substitute. It can be found in various "sugar-free" products, including gums, candies, and even toothpastes. Xylitol is popular because its flavor closely resembles that of regular sugar. Xylitol may be listed on product labels under the code E967, as noted on the European Food Safety Authority's website, which lists approved sweeteners in the European Union. However, Dr. Kierzek clarifies that this information shouldn't lead people to automatically consider all "sugar-free" products as harmful or healthier. The value of these products depends on the specific product, the amount consumed, and an individual's overall health condition. Dr. Kierzek's warning is based on a study that was presented at a medical congress, although the details of the study are not provided in the report. His comments highlight the need for careful consideration when choosing alternatives to sugar, especially in everyday items like coffee. He encourages people to make gradual changes to their dietary habits rather than relying on substitutes that may carry hidden risks. While xylitol is a popular choice for those looking to reduce sugar intake, it is important to understand its role and potential effects on health. Dr. Kierzek's advice reflects a broader concern about the long-term implications of artificial sweeteners and the importance of making informed dietary choices. His recommendations are aimed at promoting a balanced approach to health and nutrition, emphasizing moderation and awareness over quick solutions.
