What it is

Sucralose is a synthetic non-nutritive sweetener approximately 600 times sweeter than sucrose. It is made by chlorinating sugar molecules. It is used in diet beverages, sugar-free snacks, chewing gum, and products marketed as low-calorie or sugar-free.

SEVERE in beverages for children under 6 / CAUTION in food

WHO issued guidance in 2023 recommending against the use of non-sugar sweeteners for weight control, with particular caution for children. Emerging research suggests disruption of gut microbiome composition. Higher concern in beverages due to greater volume of consumption and direct GI exposure.

Why it matters

WHO 2023: non-sugar sweeteners not recommended for weight control in any age group
Gut microbiome disruption: alters composition and function of intestinal bacteria
Limited long-term pediatric safety data
May impair glucose tolerance and insulin sensitivity
Thermal degradation: produces chloropropanols when heated above 120C (baking concern)

Who should care most

Children under 6 (highest concern in beverages). All children consuming non-sugar sweeteners regularly. Individuals with existing glucose intolerance.
