#Erythritol

A widely used sugar substitute, erythritol, commonly recommended for people with obesity or diabetes and found in an array of “sugar-free” products, is at the center of fresh health warnings after recent research linked it to damaging effects on brain cells and an increased risk of stroke SciTechDaily.

This finding, from a new study by researchers at the University of Colorado Boulder, raises important questions for Thai consumers who increasingly turn to artificial sweeteners in their efforts to manage weight, diabetes, and blood sugar—problems that are highly prevalent in Thailand and have changed consumption habits nationwide. As health-conscious lifestyles prompt a shift toward “no sugar” or “sugar-free” foods, the safety of these sugar alternatives is becoming a matter of significant public interest.

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 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.
