Sucralose

Group: Sweeteners · in the book

Harm level3 of 5In moderation

In plain words

Sucralose is an artificial sweetener made from sugar, about 600 times sweeter and calorie-free. You find it in diet drinks, protein powders, bars and baking sweeteners.

Where you find it: sugar-free gum, 'zero' drinks, light yoghurts

Our recommendation

Limit it and do not use it for high-temperature baking.

Possible risks and effects

  • Possible reduction of gut microbiome diversity.
  • Chlorinated compounds may form when baked at high temperatures.
  • Long-term human data are limited.

For experts

Sucralose is a chlorinated derivative of sucrose (three hydroxyl groups replaced by chlorine) that is mostly not absorbed and is excreted in faeces. The EU authorised it in 2004; EFSA's re-evaluation is still ongoing. Open questions include effects on the gut microbiome, in-vitro genotoxicity of the impurity sucralose-6-acetate and formation of chlorinated compounds when heated to high temperatures.
