Fatty acid signatures defined and their proposed roles
The review defines fatty acid signatures as the relative distribution of saturated, monounsaturated and polyunsaturated fatty acids within specific biological compartments. It describes them as integrated indicators of dietary lipid exposure, endogenous metabolism and tissue-specific lipid remodeling. Rather than serving solely as biomarkers of nutritional intake, the review states that these signatures influence membrane architecture, cellular signaling, inflammatory regulation, mitochondrial function and gene expression, linking dietary lipid quality with metabolic health, chronic disease susceptibility and biological aging.

Review focus: cardiometabolic, neuroinflammation, cognition, longevity
The review critically synthesized current evidence on the biosynthesis, regulation, analytical assessment and biological significance of fatty acid signatures. Particular emphasis was placed on cardiometabolic health, neuroinflammation, cognitive aging and healthy longevity. It distinguishes the complementary roles of conventional fatty acid profiling and high-resolution lipidomics in resolving fatty acid composition and molecular lipid species.

Analytical limits and proposed integration with other omics
The review highlights persistent analytical challenges, including biological matrix specificity and the limited resolution of positional and geometric fatty acid isomers. It examines how integrating lipidomics with nutrigenomics, metabolomics, foodomics and emerging computational approaches could improve mechanistic interpretation, biomarker discovery and precision nutrition. The review concludes that fatty acid signatures are dynamic metabolic phenotypes connecting dietary exposure with membrane biology, metabolic regulation and healthy aging, and calls them a promising foundation for evidence-based nutritional strategies and next-generation functional food research.

How to interpret this
This is a review; the supplied text is only the abstract, and the full text was not reviewed. The abstract reports no primary study design, sample, follow-up or effect sizes, so the described links between fatty acid signatures and health, disease or aging are presented as review-level synthesis, not as established causal relationships.
Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
