What The Sources Report

  • This review synthesizes current evidence on the effects of both plant- and animal-derived foods on cognitive outcomes from early development through older adulthood. [Hardaway C (2026); evidence level 4]
  • Evidence was evaluated across life stages, considering nutrient bioavailability, dietary patterns, and the interplay between structural, socioeconomic, and environmental factors that influence access to these foods. [Hardaway C (2026); evidence level 4]
  • These manifestations not only affect daily functioning and productivity but also contribute to long-term health consequences, including reduced social engagement, impaired occupational performance and increased healthcare utilization. [Ray Prama (2026); evidence level 4]
  • Although these symptoms are often attributed solely to hormonal shifts, emerging evidence suggests that nutritional deficiencies may play a significant and potentially modifiable role in the pathophysiology of perimenopausal fatigue and mood disorders. [Ray Prama (2026); evidence level 4]

How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

Practical Interpretation

For vitamin D mood randomized trial, the current source set is useful for orientation, but it is not yet broad enough for strong claims. Use cautious language and keep conclusions close to the cited sources.

Limits Of This First Pass
