The Claim
Based on current evidence, the consumption of low/no-calorie sweeteners—including acesulfame K, aspartame, cyclamate, neotame, saccharin, sucralose, and steviol glycosides—is not associated with adverse effects on human health, even though some rodent studies have reported microbiota changes at high, non-relevant doses.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Eating sugar substitutes like Splenda or Sweet'N Low doesn't seem to hurt your health, based on what we know now—even though some mouse studies saw gut changes when they gave way too much.

Consumption of low/no-calorie sweeteners such as acesulfame K, aspartame, cyclamate, neotame, saccharin, sucralose, and steviol glycosides is not associated with adverse effects on human health based on current evidence, despite some rodent studies showing microbiota changes at high, non-relevant doses.
What the research says
1 studyStudy: Assessing the in vivo data on low/no-calorie sweeteners and the gut microbiota.
This study looked at artificial sweeteners and found that even though some mouse studies showed gut changes, those used way more sweetener than people ever eat — and humans didn’t show any harm. So, the sweeteners are probably safe at normal doses.
