The Claim

In children, replacing sugar with non-sugar sweeteners is associated with a smaller increase in body mass index z-score over time compared to sugar consumption, with a mean difference of -0.15.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Children who consume non-sugar sweeteners instead of sugar experience a smaller increase in body mass index z-score over time compared to children who consume sugar.

See the scientific wording

In children, replacing sugar with non-sugar sweeteners is associated with a smaller increase in body mass index z-score (mean difference -0.15) over time compared to sugar consumption, based on moderate-certainty evidence from two randomized controlled trials involving 528 children, suggesting a potential benefit in slowing weight gain during growth.

Why this might work

When children consume drinks with non-sugar sweeteners instead of sugar, they take in fewer calories. This means their bodies have less extra energy to store as fat, so they gain less weight over time.

    Kids who drink drinks with artificial sweeteners instead of sugar tend to gain a little less weight over time, according to a review of two studies with hundreds of children. It’s a small difference, but it points in the right direction.
