While its role in damaging cellular components such as membranes, proteins, and DNA is well-documented, a significant translational gap persists between our mechanistic understanding and the development of effective clinical interventions. This review critically examines this disconnect by proposing and applying a three-tiered analytical framework. First, we identify and compare the hierarchy of initial molecular targets (e.g., mitochondrial cardiolipin, LDL phospholipids, specific protein thiols) across diseases, arguing that this hierarchy dictates pathological specificity. Second, we trace how these initial insults propagate through shared yet context-dependent mechanistic themes\u2014metabolic dysregulation, inflammatory amplification, and cell death decisions\u2014to drive organ-specific pathology. Third, we synthesize and critically evaluate current and emerging therapeutic strategies (e.g., antioxidants, ferroptosis inhibitors, nutritional modulation) against this mechanistic backdrop, highlighting their potential, limitations, and the need for mechanism-informed, personalized approaches. By moving beyond a descriptive catalog of effects, this review aims to provide a dynamic, intervention-oriented perspective essential for bridging basic science discoveries with translational innovation in combating lipid peroxidation-associated metabolic disorders.<\/jats:p>","DOI":"10.3389\/fmolb.2026.1793466","type":"journal-article","created":{"date-parts":[[2026,3,2]],"date-time":"2026-03-02T06:32:35Z","timestamp":1772433155000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Research progress on the damage of lipid peroxidation to the body and its correlation with metabolic diseases"],"prefix":"10.3389","volume":"13","author":[{"given":"Jiali","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Medicine and Food, Laiwu Vocational and Technical College","place":["Jinan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongli","family":"Li","sequence":"additional","affiliation":[{"name":"College of Medical Technology, Chongqing Medical and Pharmaceutical College","place":["Chongqing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuhan","family":"She","sequence":"additional","affiliation":[{"name":"College of Medical Technology, Chongqing Medical and Pharmaceutical College","place":["Chongqing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chongli","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Medical Technology, Chongqing Medical and Pharmaceutical College","place":["Chongqing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kun","family":"Peng","sequence":"additional","affiliation":[{"name":"College of Medical Technology, Chongqing Medical and Pharmaceutical College","place":["Chongqing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenqiao","family":"Ding","sequence":"additional","affiliation":[{"name":"College of Biology and Food Engineering, Jilin University of Chemical Technology","place":["Jilin, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,3,2]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"2","DOI":"10.1038\/s41392-024-02088-5","article-title":"In defence of ferroptosis","volume":"10","author":"Alves","year":"2025","journal-title":"Signal Transduct.
