Mexico put warning labels on dairy products that have artificial sweeteners, and as a result, companies started using way fewer of those sweeteners—down by almost a third. Meanwhile, Chile and Peru didn’t warn about sweeteners, and they actually started using more. So, it looks like warning people about artificial sweeteners might push companies to stop putting them in food.

Assessment Explanation
The claim uses 'associated with' and contrasts trends across countries, which is appropriate for observational, cross-national policy evaluation studies. It does not claim causation, which is correct given the lack of randomized control. The 29.0 percentage point figure suggests specific data from a study, and the comparison with Chile and Peru as controls strengthens the inference. However, without controlling for confounders (e.g., economic trends, other regulations), the conclusion that the policy 'may discourage' use is reasonable but not definitive. The verb 'suggesting' appropriately reflects the inferential nature.
More Accurate Statement
“The implementation of Mexico's front-of-pack warning label policy, which includes non-caloric sweeteners as a warning trigger, is associated with a reduction of up to 29.0 percentage points in the proportion of solid dairy products containing non-caloric sweeteners, compared to increases in Chile and Peru, suggesting that including non-caloric sweeteners as a warning trigger may discourage their use as sugar substitutes.”

Evidence from Studies
Supporting (1)
After Mexico put warning labels on unhealthy foods, companies stopped adding artificial sweeteners to dairy products to avoid the labels, and the study shows this led to a big drop—up to 29% fewer products had them.
