Among five front-of-package systems, nutrient-specific 'high in' warnings most consistently shifted incentivized beverage and snack purchases toward lower targeted nutrients, but effects were outcome-specific rather than universal.
What this does not establish
The money was provided, only one of eight choices was fulfilled, and the experimental assortment cannot establish household consumption, repeat purchase, health effects or identical effects in live retail.
Counterevidence & uncertainty
The same warning did not significantly lower snack sugar or saturated fat, and other summary labels were less consistent; 'a label works' is too coarse a conclusion.
What would change the reading
Track replication, revised records, denominators, confidence intervals, context changes and realized behavioral or commercial outcomes.
