Abstract

fetched live from OpenAlex

One of the primary preventative measures of non-communicable diseases is a healthy diet. There is currently no oversight of the nutritional quality of foods served in the restaurant industry, meanwhile increasing numbers of Canadians eat outside the home on a regular basis. This thesis aimed to assess mean saturated fat, sodium, and sugar levels in restaurant foods in Canada, and to determine the proportion of menu items that would require one of Health Canada’s ‘high-in’ labels if applied to the restaurant sector. Analyzing data from 10,950 menu items from 96 chain establishments, this thesis represents the largest study of its kind in Canada. Our results showed the majority of menu items evaluated were high in nutrients of public health concern, and would require at least one ‘high-in’ label. This highlights the urgent need for more legislation and strategies to improve the nutritional quality of restaurant foods in Canada.

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.
