Abstract

fetched live from OpenAlex

This thesis reports the results of a study investigating the impact of functional food consumption on broader dietary choices. A theoretical framework of individual response to regulatory protection is adapted to investigate potential offsetting behaviour in the context of averting behaviours undertaken to improve health and/or reduce the risk of illness such as functional food consumption. Data was collected through two online surveys using a representative consumer panel in Guelph, Ontario, Canada. Estimation of probit models for two types of offsetting behaviour namely increased overall consumption of a functional food carrier and reduced propensity to make health dietary choices suggest that the addition of a functional ingredient to a food may lead to increased overall consumption of that food; however the probability of that occurrence is low. Empirical results do not support that consumption of a functional food reduces the propensity to make healthy dietary choices.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
