The Claim

Replacing sugar-sweetened beverages with artificially sweetened beverages for 12 months has no significant effect on sweet taste threshold in humans.

Description
1 study reviewed
In plain English

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.

Why this might work

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.

    Drinking 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.
