Introduction: Nutrition drives a large share of preventable morbidity,
yet preclinical curricula often emphasize biochemical pathways while
underutilizing tissue-level correlates that anchor mechanism to diagnosis.
Nationally, nutrition exposure is broad but uneven, with a shift toward
competency-based, longitudinal learning rather than hour counts. The aimed to
map where micronutrient content appears in OUWB’s early curriculum and
identify opportunities to better integrate histologic images that visually
anchor nutrient mechanisms, strengthen diagnostic reasoning, and reinforce
board-relevant retention.
Methods: Using a standardized checklist from the faculty project plan, we
reviewed foundational sessions categorized as nutrition-adjacent along with
basic tissues histology laboratories. For sessions we recorded: (1) whether a
micronutrient explicitly mentioned; (2) the number of histologic image linked
to those nutrients; (3) the number of objectives or assessments including
nutrient-histology connections; and (4) the OUWB competencies each pairing
could reinforce.
Results: Across 11 didactic sessions and four laboratories, micronutrients
were explicitly discussed in six of 11 sessions. Only two sessions paired
nutrients with tissue level images that make mechanisms visually concrete.
All four laboratories focused structure identification, but none explicitly
connected slides to common deficiencies. Current mapping shows frequent
nutrition coverage but inconsistent linkage to histology. The mapping also
revealed multiple opportunities to embed nutrient-histology connections that
directly support course competencies small image banks and formative
assessment items.
Conclusion: We propose a cross-course, image-anchored “histologic clues”
thread that inserts high yield images into selected sessions or laboratories,
each labeled with the nutrient, mechanism, and related objective. This
approach shifts evaluation toward demonstrable diagnostic reasoning without
increasing contact hours. Focused integration is feasible, competency
aligned, and likely to improve retention and exam readiness. Next steps
include extending the map to remaining organ system courses, building a
curated image bank, and assessing pre- and post-performance on
nutrient-related histology spot checks.
