<\/p>\nFish oil has been hailed as one of the best supplements for brain health, but new findings have called this widely held belief into question.<\/p>\n
The compound has previously been recognised for its ability to reduce inflammation, positioning it as a key player in the fight against cardiovascular disease.<\/p>\n
And while scientific evidence has repeatedly suggested it is one of the most important components of a healthy diet, evidence for the benefits of taking supplements has been less conclusive.<\/p>\n
The latest body of research looking at the neurovascular system has suggested that fish supplements could do more harm than good for certain people.<\/p>\n
Fish oil has long been lauded for its anti-inflammatory effects<\/p>\n

Lead author Onder Albayram, PhD, neuroscientist and associate professor at the Medical University of South Carolina and a member of the National Trauma Society Committee, said: \u201cFish oil supplements are everywhere, and people take them for a range of reasons, often without a clear understanding of their long-term effects.<\/p>\n
\u201cWe still don\u2019t know whether the brain has resilience or resistance to this supplement.\u201d<\/p>\n
The findings, published in Cell Reports, suggest a specific chemical compound known as EPA could disrupt the brain\u2019s healing process after an injury.<\/p>\n
More specifically, it appeared to make the walls of the brain\u2019s blood vessels less stable, presenting a challenge for blood vessels that need to repair themselves following an injury.<\/p>\n
Fish oil disrupts repair signals put out by the brain after physical trauma, the researchers noted. <\/p>\n
They also discovered a link between the supplement and a build-up of tau protein, which is linked to brain illnesses.<\/p>\n

It’s worth noting that the effects were observed in mice, meaning further research is needed to establish what the impact would be on people.<\/p>\n
Furthermore, scientists focused on cases of \u201crepeated mild head injuries\u201d. Consequently, the findings may not apply to anyone who has not suffered an injury to the head.<\/p>\n
\u201cI am not saying fish oil is good or bad in some universal way,\u201d Professor Albayram said. \u201cWhat our data highlight is that biology is context-dependent. <\/p>\n
\u201cWe need to understand how these supplements behave in the body over time, rather than assuming the same effect applies to everyone.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Fish oil has been hailed as one of the best supplements for brain health, but new findings have…\n","protected":false},"author":3,"featured_media":767340,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[37],"tags":[632,210,50,1182,1156,67,132,68],"class_list":["post-767339","post","type-post","status-publish","format-standard","has-post-thumbnail","category-nutrition","tag-dementia","tag-health","tag-news","tag-nutrition","tag-sgg","tag-united-states","tag-unitedstates","tag-us"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/116502898204224671","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/767339","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=767339"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/767339\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/767340"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=767339"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=767339"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=767339"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
