The Claim

Non-nutritive sweeteners significantly reduce sugar intake by 1.78 standardized units compared to sugar in adults, confirm their effectiveness in displacing added sugars, but show no significant effect when compared to water.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

If you swap sugar for artificial sweeteners, you’ll eat less sugar—by a lot—but if you drink water instead, you get the same low sugar intake, so the sweeteners don’t help any more than water does.

What the research says

1 study

  1. Study: The effects of non-nutritive sweeteners on energy and macronutrients intake in adults: a grade-assessed systematic review and meta-analyses of randomized controlled trials

    This study found that people who used artificial sweeteners instead of sugar ate less sugar and fewer calories, but when they used sweeteners instead of plain water, they didn’t eat less — just like the claim says.
