Abstract

fetched live from OpenAlex

• The aging population in Italy faces health challenges related to diet. • NutriScore affects health perceptions and lowers taste expectations of food products. • Dietary regime generally increases perceived healthiness of products with NS. The growing aging population presents significant public health challenges worldwide, particularly in terms of nutrition and diet-related diseases. In Italy, where more than a quarter of the population is aged 65 and older, this issue is especially pressing. Many elderly individuals struggle to make nutritionally informed choices due to limited awareness and knowledge about food quality. This study examines the impact of the Nutri-Score (NS) label on the perceived healthiness of food products among Italian older adults. Applying a within-subjects experimental design, 557 elderly consumers, partially or fully responsible for household food shopping, evaluated five commonly consumed products—pasta, extra virgin olive oil, mozzarella cheese, canned tuna in olive oil, and milk chocolate bar—both with and without the NS label. Findings reveal that the NS significantly impacts health perceptions and decreases taste expectations across food products. Additionally, individual characteristics such as dietary habits and NS knowledge influence these changes. Policy makers and stakeholders should further explore the appropriateness of NS as an effective method to guide elderly consumers toward healthier food choices.

Teacher imitation

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.
