Sucralose (Splenda) is a no-calorie artificial sweetener around 600× sweeter than sugar. Research links it to changes in the gut microbiome, and it may form harmful compounds when heated.

Digestoa's take

You don't need to panic over a single product that contains Sucralose. But it's a useful flag: when you see E955 on a label it often signals a more processed product, and there's usually a cleaner alternative.

Safer swaps

Try products sweetened with stevia (E960) or erythritol, or simply less sweetness.
