## What The Sources Report

- Longevity is not only the result of genetic inheritance, but it also reflects the complex interplay between environmental, biological, and behavioral factors accumulated across the life course. [Martini Daniela (2026); evidence level 3]
- However, although the association between diet and healthy aging is widely recognized, the strength and consistency of evidence vary substantially across outcomes, populations, and study designs. [Martini Daniela (2026); evidence level 3]
- Aside from the complex mechanisms contributing to brain fog and its links to various medical conditions, research suggests that certain risk factors may also influence the occurrence of this cognitive symptom cluster. [Altınsoy Canan (2026); evidence level 3]
- Female sex has been identified as a notable risk factor, with studies reporting a higher prevalence of brain fog among women. [Altınsoy Canan (2026); evidence level 3]

## 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 cacao sleep quality meta-analysis, 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

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
