Abstract

fetched live from OpenAlex

OBJECTIVE: To determine if nutritional information on an alcohol container influenced consumer perceptions of product healthiness, and whether the effect of information differed by display format. METHODS: Online randomized controlled trial among adults in Canada sampled from a commercial panel (analytical sample n = 3880) in November/December 2024. Participants were randomized to view a wine product in one of four conditions: (1) control (no label), (2) Nutrition Facts table (NFT), (3) textual nutrition information, (4) Alcohol Facts table, and were asked "How healthy would it be to drink this wine regularly?" (7-point Likert-type item, very unhealthy to very healthy). Logistic regression compared the likelihood of rating the product as "a little healthy/healthy/very healthy" between conditions. RESULTS: Compared to the control (16.5 %), those in the NFT condition had higher odds of rating the product as "a little healthy/healthy/very healthy" (28.3 %, AOR = 1.97, 95 %CI,1.57,2.47), as did those in the textual nutrition information condition (23.8 %, AOR = 1.60, 95 %CI,1.27,2.02). There were no differences between the control condition and the Alcohol Facts table condition (18.8 %). CONCLUSIONS: Nutritional information on alcohol products may lead consumers to falsely believe products are 'healthier'. Label design and features that make alcohol products distinct from non-alcoholic food and beverages may reduce unintended impacts.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
