What the literature leaves open

  • Although exercise training can increase insulin sensitivity and levels of specific FAHFA in AT and the circulation in humans, the effects of acute exercise on FAHFA levels remain unclear.

  • Environmental factors, including aging, infections, lifestyle, toxins, and stress, have been associated with lipid dysregulation as a plausible common mechanism elevating stroke risk (GBD 2019 Stroke Collaborators, 2021; GBD 2021 Stroke Risk Factor Collaborators, 2024; Wang Y. et al., 2025). The central argument of this review is that environmental exposures converge on lipid metabolic pathways through shared cellular mechanisms, creating cumulative metabolic vulnerability. However, the causal relationships between specific environmental exposures, lipid dysregulation, and stroke outcomes are established to varying degrees, ranging from strong clinical trial evidence for smoking cessation and statin therapy to mechanistic hypotheses that require prospective human validation for most of the cellular pathways discussed.

  • Further, other percent of dietary GSC inclusion need to be investigated in order to obtain a more complex response related to biomarkers which characterise the fattening/obesity process.

  • Although several studies have analyzed the fatty acid profile of phospholipids (PL) and, to a lesser degree, triacylglycerols (TG) in one or more tissues concurrently, a systematic comparison of the fatty acid composition of different tissues and/or lipid classes is lacking.
