Abstract
The countries of Central America have been pioneers in the developing world regarding food fortification initiatives. Salt fortification with iodine was introduced since the late 40s and 50s; sugar fortification with vitamin A is carried out in national programs in Guatemala, Honduras, El Salvador, and Nicaragua, beginning in the 70s; and cereal flour fortification with iron and B vitamins was introduced in the 60s. Salt and sugar fortification have been carefully characterized and evaluated, and the impact of these two interventions to prevent and to control iodine and vitamin A deficiency, respectively, is well established. This did not happen with cereal flour fortification, however, and the effect of this intervention is unknown. Nevertheless, some lessons can be extracted from our experience; these will be discussed in this review.

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
