#ArtificialSweeteners

A ubiquitous sugar substitute found in Thai supermarkets, bakeries, bubble tea shops, and increasingly in “health” products, erythritol, has emerged as a fresh concern for heart health. Recent scientific studies—including a major investigation led by the University of Colorado Boulder—reveal that consuming even a typical serving of erythritol may rapidly trigger changes in blood vessels and platelets that set the stage for heart attack and stroke. With sugar-free and “keto” diets growing in popularity across Thailand, these findings carry weighty implications for millions of Thai consumers who have long considered erythritol as a harmless alternative to sugar.

A series of recent studies has reignited the debate over whether drinking diet soda could be more effective than water in helping some people shed extra kilos, with researchers and nutritionists weighing in on the controversial claim. The renewed interest comes after social media buzz and resurfaced research suggesting that people drinking artificially sweetened beverages daily—rather than water—lost significantly more weight over the course of a year. The findings, however, have sparked both optimism and concern among health experts, with implications that extend to Thailand’s growing public health challenges associated with obesity and metabolic disease.

A new study presented at the 2025 American Physiology Summit has reignited concerns over the safety of artificial sweeteners—specifically erythritol, a popular sugar substitute found in countless sugar-free and “diet” products worldwide. Researchers report that erythritol may trigger cellular changes that heighten the risk of stroke and heart attack—an alarming development for consumers and health officials alike as the use of sugar substitutes remains widespread, including in Thailand’s urban and health-conscious communities.

As diet sodas, low-calorie snacks, and “sugar-free” treats line supermarket shelves across Thailand, consumers are turning in increasing numbers to artificial sweeteners in hopes of enjoying sweet flavors without the adverse health effects of sugar. However, a growing wave of scientific research is challenging the widespread belief that artificial sweeteners are a healthier choice, suggesting instead that these calorie-free sugar substitutes may bring their own health risks — including increased appetite, fat accumulation, and potentially heightened risk of obesity and type 2 diabetes, according to a recent exposé published by The Independent and corroborated by the latest global studies (The Independent).
