Evidence Update

Current evidence

Nonhuman context for resveratrol: selected cortical vascular, expression and cell-survival readouts changed in male rhesus monkeys fed a high-fat/high-sucrose diet; these findings do not demonstrate improved cognition, survival or human longevity. A distinct long-term male mouse-lemur study did not find a significant survival benefit, despite better midlife task performance, and reported an exploratory late-life focal grey-matter-loss signal.

What changed

Distinct rhesus tissue and mouse-lemur longitudinal contexts are added, retaining null survival and inflammatory measures and the exploratory focal imaging caution.

What did not change

These animal findings do not establish human benefit or generalized human harm and do not supersede accepted human evidence.

Why it matters

Species, dose, diet, endpoint and observation window must remain attached to each resveratrol finding; separate experiments are not interchangeable replications.

Main limitation

Small standard-diet group, many tissue assays, quasi-random allocation, males only, no cognitive/survival endpoint. Earlier organ reports used the same cohort, not independent replications. Small male-only cohort and dose-specific result; MRI p less than .005 uncorrected,75-voxel threshold. Survival p-values differ between text/caption and behavioral control denominator differs; do not publish an exact p-value or harmonized n without clarification. Different observation windows limit brain-behavior inference.

Next proof

Independent replication and prespecified functional outcomes within species before any human translation. Dose/sex-diverse replication, harmonized behavior/imaging follow-up and corrected source denominators/statistics.

    What this source establishes Reports survival, behavior and brain-imaging findings in a separate long-term male mouse-lemur resveratrol study.

    Important limitation No significant survival benefit; exploratory imaging and inconsistent reported denominators/statistics limit inference and human translation.

    Source type nonhuman_primate_tissue Publication date 2016-04-09

    What this source establishes Reports selected cortical vascular, expression and inflammatory findings with resveratrol in male rhesus monkeys on a high-fat/high-sucrose diet.

    Important limitation Small quasi-randomized animal study with multiple assays; no cognition or survival endpoint, and earlier organ reports use the same cohort.

    Evidence access Relevant full-text sections reviewed.

Summary

Nonhuman context for intervention intelligence: Resveratrol modified selected cortical vascular, expression and cell-survival readouts in HFS-fed male rhesus monkeys; the findings do not demonstrate improved cognition, survival or human longevity. A distinct long-term male mouse-lemur study did not find a significant survival benefit, despite better midlife task performance, and reported an exploratory late-life focal grey-matter-loss signal.

Intelligence Take

Species, dose, diet, endpoint and observation window must remain attached to each resveratrol finding; separate experiments are not interchangeable replications.
