The Claim
Current evidence from randomized controlled trials does not support a meaningful effect of low- and no-calorie sweeteners on gut microbiome composition or glucose tolerance in healthy adults at typical consumption levels.
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.
Studies with people who drink diet sodas or eat foods with artificial sweeteners don’t show that these sweeteners change the good bacteria in your gut or how your body handles sugar, as long as you’re eating or drinking them in normal amounts.

Current evidence from randomized controlled trials does not support a meaningful effect of low- and no-calorie sweeteners on gut microbiome composition or glucose tolerance in healthy adults at typical consumption levels.
What the research says
1 studyThe review summarizes multiple RCTs that tested NNSs at realistic doses and found no significant changes in microbiome diversity or glucose tolerance, directly contradicting earlier observational claims. This refutes a major safety concern raised in popular media.
