Marine fish is established as cardioprotective in fatty-fish-consuming coastal populations, yet this benefit appears to break down in South Asian contexts. This commentary interrogates four interlocking mechanisms. First, aquaculture-driven species substitution has replaced\n                    <jats:italic>n<\/jats:italic>\n                    -3-rich species such as hilsa and coastal sardines with leaner farmed varieties offering only a fraction of the cardioprotective lipid profile. Second, deep frying in high-\n                    <jats:italic>n<\/jats:italic>\n                    -6 oils substantially degrades PUFA bioavailability. Third, heavy metal co-contamination in arsenic- and mercury-affected watersheds may attenuate\n                    <jats:italic>n<\/jats:italic>\n                    -3 benefits. Fourth, urbanisation is eroding fish intake among the highest-risk subgroups, while aggregate dietary data obscure this heterogeneity. Generic eat-more-fish guidance is insufficient; ethnicity-sensitive, sustainability-conscious guidance on species, preparation and contamination risk is needed to realise fish\u2019s cardioprotective potential in South Asia.\n                  <\/jats:p>","DOI":"10.1017\/s1368980026103140","type":"journal-article","created":{"date-parts":[[2026,7,20]],"date-time":"2026-07-20T06:18:21Z","timestamp":1784528301000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":1,"title":["When fish fails to protect: interrogating the South Asian cardiometabolic paradox in the era of aquaculture transition"],"prefix":"10.1017","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9112-3660","authenticated-orcid":false,"given":"Abu Ansar Md","family":"Rizwan","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/0405mnx93","id-type":"ROR","asserted-by":"publisher"}],"name":"Texas Tech University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2026,7,20]]},"container-title":["Public Health Nutrition"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S1368980026103140","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,12]],"date-time":"2026-08-12T06:50:05Z","timestamp":1786517405000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S1368980026103140\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2026]]}},"alternative-id":["S1368980026103140"],"URL":"https:\/\/doi.org\/10.1017\/s1368980026103140","relation":{},"ISSN":["1368-9800","1475-2727"],"issn-type":[{"value":"1368-9800","type":"print"},{"value":"1475-2727","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026]]},"assertion":[{"value":"\u00a9 The Author(s), 2026.
