This paper synthesizes blue zones diet lifestyle as an aging-related intervention across 50 included source papers and 1736 high-confidence extracted claims. The evidence profile contains no sources classified primarily as direct clinical evidence, 40 adjacent clinical sources, and 4 mechanistic or model-system sources, with 528 cross-study disagreements across the evidence base. Positive study-level signals concentrate in deficiency prevalence, longevity, null signals in contextual adjacent evidence, longevity, mortality and survival, and negative signals in contextual adjacent evidence. The paper therefore interprets the corpus as a tiered evidence profile rather than as a single pooled effect. The conclusion is that blue zones diet lifestyle remains a bounded geroscience case: mechanistic plausibility and selected clinical signals justify further targeted testing, while mixed and null findings limit any unqualified anti-aging claim.
