Longevity in the Blue Zones cannot be reduced to diet alone; it depends on a multitude of factors that extend far beyond the plate.

Stuart Phillips highlights an important limitation in the popular interpretation of the Blue Zones. Scientific research indeed supports this holistic view: while diet plays a role, observational studies (such as those published in the 'American Journal of Lifestyle Medicine') confirm that social connection, natural physical activity, and stress management are fundamental pillars. Reducing these lifestyles to a list of ingredients is a simplification that obscures the importance of the social environment and daily movement. Data show that genetics, while present, are often surpassed by overall lifestyle habits. It is therefore scientifically accurate to state that diet alone is insufficient to explain the exceptional longevity observed in these regions. The approach is consistent with the current consensus on integrative health.
