After Peru started putting warning labels on super-sweet drinks, companies changed their recipes to use less sugar and more artificial sweeteners, so fewer drinks now need the warning label.

Assessment Explanation
The claim reports an observed change in proportions over time following a policy intervention, which can be directly measured using sales and formulation data collected before and after policy implementation. This is a descriptive claim based on population-level surveillance data, which is commonly and reliably collected in public health policy evaluations. The use of 'decreased' is appropriate because it reflects an empirical trend observed in a defined population over a specific time frame. No causal claims are made about health outcomes, only about product reformulation and labeling status, which are directly measurable.
More Accurate Statement
“Two years after the implementation of a front-of-package warning label policy in Peru, the proportion of top-selling beverages qualifying for such labels decreased from 59% to 31%, primarily due to reformulations that reduced sugar content and increased the use of nonnutritive sweeteners.”

After Peru put warning labels on unhealthy drinks, companies changed their recipes to have less sugar and more artificial sweeteners, so fewer drinks now needed the warning label. The study proves this happened.
