Abstract
This paper evaluates if Morin-Chartier’s content analysis, when adapted to Portuguese, can successfully be applied to texts on health and diet published in a Brazilian newspaper. This is a cross-section study. The texts were collected from the Brazilian newspaper O Dia between January 2014 and July 2015. Texts written on the subject of health and diet were analyzed, and specific software was used to evaluate how often they appeared in various categories. The method demonstrably categorizes and classifies different subjects within a single text, and thus helping to minimize any errors. A total of 1.668 information units were extracted from a collection of 341 journalistic texts. These information units focused on the effects foods have on the body and recommendations for which foods to consume. Most of these foods were in natura but there were some ultra-processed as well. The texts are taken from the Brazilian press, and the sources, when identified, are specialists on the subject. The texts are written with the intent to promote health.A pesquisa avalia a aplicabilidade do método canadense de análise de conteúdo de Morin-Chartier em textos sobre saúde e alimentação, apresentados pelo jornal popular brasileiro O Dia, entre janeiro de 2014 e julho de 2015. A análise se baseia no registro das unidades da informação na imprensa que tratam sobre o tema alimentação, e avaliação de sua frequência em diferentes categorias com produção e uso de software específico. O método possibilitou que diferentes assuntos no mesmo texto fossem categorizados e classificados distintamente, minimizando falhas. Dos 341 textos jornalísticos coletados, extraiu-se 1.668 unidades da informação, observando enfoque em recomendações e efeitos dos alimentos, com maior presença dos in natura em detrimento dos ultraprocessados. A origem dos textos é nacional e as fontes, quando identificadas, são especializadas, em sua maioria. O engajamento dos textos é favorável à saúde.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
