Adjacent Evidence Brief: Plant based diet biological age — full paper

Researka accepted publication: 85440cfa-aa74-4ac3-983b-efad9e093f27 Source submission: a5089c76-8f6d-47f2-a47c-f07af49a364c This synthesis tests the thesis that evidence for Plant based diet biological age is context-dependent, separating outcome-specific signals from broader claims and identifying the evidence gaps that should bound interpretation. Evidence-honesty note: 8/13 retained sources are coded as null or no extracted directional signal; this corpus is non-supportive for clinical efficacy claims and hypothesis-generating only. Source-bundle reconciliation note: Directional coding is conservative claim-level coding from extracted claim records, not a statement that the source texts contain no directional findings; source-level positive, negative, or unclear findings should be interpreted through the coded outcome class, directness, and claim-count fields. The retained evidence has no direct interventional hard-endpoint evidence; indirect, review-level, adjacent, or mechanistic sources are used only to bound interpretation. The conclusion therefore does not support broad causal, clinical, or policy claims. This paper synthesizes evidence on Plant based diet biological age across 13 included source papers and 369 high-confidence extracted claims.
