The Claim
Replacing sugar-sweetened beverages with artificially sweetened beverages for 12 months has no significant effect on sweet taste threshold in humans.
What the research says
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.
Switching from sugary drinks to drinks with artificial sweeteners for 12 months does not change how sensitive a person is to sweet tastes.
See the scientific wording
Replacing sugar-sweetened beverages with artificially sweetened beverages for 12 months does not significantly alter sweet taste threshold, indicating that artificial sweeteners may not induce the same sensory adaptation as unsweetened beverages.
Artificial sweeteners strongly activate sweet taste receptors on the tongue, but because they provide no calories, the brain does not receive the expected metabolic signal. This incomplete signal prevents the full reduction in sensitivity to sweetness that occurs when sweet tastes are completely removed. As a result, the threshold for detecting sweetness stays the same, even after long-term use.
What the research says
1 studyDrinking diet soda for a year didn’t make people need less sugar to taste sweetness, but drinking water did. So diet soda doesn’t retrain your taste buds like water does.
