The Claim

In adults, replacing sugar with non-sugar sweeteners is associated with a reduction in daily sugar intake by approximately 89.7 grams.

In plain English

When adults replace sugar with non-sugar sweeteners, their daily sugar intake decreases by about 89.7 grams.

See the scientific wording

In adults, replacing sugar with non-sugar sweeteners is associated with a reduction in daily sugar intake by approximately 89.7 grams, based on very low-certainty evidence from three randomized controlled trials involving 135 participants, indicating a potential behavioral substitution effect that may not translate to meaningful health outcomes.

Why this might work

When sugar is replaced with non-sugar sweeteners, the brain continues to receive sweet taste signals, which reduces the drive to seek out sugary foods, leading to lower sugar consumption.

    People who swap sugar for artificial sweeteners tend to eat less sugar, which can help them lose a little weight and keep blood sugar lower — but the studies are small and not super reliable.
