Abstract
The concept of the protein transition represents a shift from a diet rich in animal proteins to one richer in plant-based alternatives, largely in response to environmental sustainability concerns. However, a simple swap by replacing dairy protein with plant protein will lead to lower protein quality and a lower intake of key micronutrients that sit naturally within the dairy matrix. Owing to antagonistic effects within the plant food matrix, micronutrients in plant sources exhibit lower bioavailability which is not reflected in food composition data or dietary guidelines. The dairy matrix effect includes moderation of blood lipid levels in which calcium plays a key role. Protein recommendations often take a muscle-centric approach. Hence, strategies to increase the anabolic potential of plant proteins have focused on increasing total protein intake to counter the suboptimal amino acid composition relative to dairy protein or leucine fortification. However, emerging evidence indicates a role for nutrient interactions and non-nutrient components (milk exosomes, bioactive peptides) of the dairy matrix in modulating postprandial muscle protein synthesis rates. To ensure the food system transformation is environmentally sustainable and optimal from a nutrition perspective, consideration needs to be given to complementary benefits of different food matrices and the holistic evaluation of foods in the protein transition. This narrative review critically examines the role of dairy in the protein transition, emphasising the importance of the food matrix in nutrient bioavailability and muscle health. By considering both nutritional and sustainability perspectives, we provide a holistic evaluation of dairy's contribution within evolving dietary patterns.

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
