Teadlased tuginesid varasematele avastustele, mis n\u00e4itasid, et flavanoolirikkad toidud ja joogid \u2013 n\u00e4iteks \u0161okolaad, roheline tee, \u00f5unad ja viinamarjad \u2013 v\u00e4hendavad oluliselt s\u00fcdamehaigustest tingitud surmajuhtumeid. Flavanoolidel on teadaolevalt v\u00f5ime leevendada liigsest p\u00f5letikust tulenevaid kahjustusi.<\/p>\n
Vaikne vaenlane: vananemisega seotud p\u00f5letik<\/p>\n
Vananedes s\u00fcveneb kehas p\u00f5letikuline protsess, mida teadlased nimetavad \u00abp\u00f5letikuliseks vananemiseks\u00bb (inflammaging). Seda seostatakse paljude vanusega kaasnevate tervisemuredega, alates kroonilisest valust kuni Alzheimeri t\u00f5veni. Kui kakaolisandid suudavad seda p\u00f5letikku v\u00e4hendada, on potentsiaalne kasu m\u00e4rkimisv\u00e4\u00e4rne.<\/p>\n
\u00abMeie huvi kakaoekstrakti ja vananemisega seotud p\u00f5letiku vastu sai alguse kakaoga seotud s\u00fcdame-veresoonkonna haiguste riski v\u00e4henemisest,\u00bb \u00fctles uuringus osalenud epidemioloog Howard Sesso Ameerika \u00dchendriikide Brigham and Women’s Hospital’ist. \u00abTahtsime n\u00e4ha, kas mitmeaastane kakaoekstrakti toidulisandi tarbimine platseeboga v\u00f5rreldes suudab seda p\u00f5letikulist vananemist m\u00f5jutada \u2013 ja andmed viitavad, et suudab k\u00fcll.\u00bb<\/p>\n
Kuidas uuring l\u00e4bi viidi?<\/p>\n
Uuringus osales ligi 600 tervet, 60-aastast ja vanemat t\u00e4iskasvanut, kes said kahe aasta jooksul iga p\u00e4ev kas 500-milligrammise kakaoekstrakti toidulisandi v\u00f5i platseebot. Selle perioodi v\u00e4ltel m\u00f5\u00f5deti nende veres leiduvaid p\u00f5letikumarkereid.<\/p>\n
Selgus, et kakaoekstrakti tarbimine aeglustas oluliselt hsCRP (k\u00f5rgtundlik C-reaktiivne valk) taseme t\u00f5usu veres. See on \u00fcldine tervisemarker, mis viitab s\u00fcsteemsele p\u00f5letikule ja suurenenud s\u00fcdame-veresoonkonna haiguste riskile. K\u00f5ige tugevam tervisem\u00f5ju ilmnes nende osalejate seas, kellel oli juba uuringu alguses v\u00e4ga k\u00f5rge s\u00fcdamehaiguste risk.<\/p>\n
Mida tulemused t\u00e4hendavad?<\/p>\n
T\u00e4psed bioloogilised mehhanismid pole veel selged, kuid teadlased kahtlustavad, et kakaoekstrakt v\u00f5ib m\u00f5jutada immuuns\u00fcsteemi reguleerivaid valke. \u00abHuvitaval kombel t\u00e4heldasime ka immuunsusega seotud ts\u00fctokiini interferoon-\u03b3 taseme t\u00f5usu, mis avab uusi k\u00fcsimusi tulevasteks uuringuteks,\u00bb s\u00f5nas kardioloog Yanbin Dong Augusta \u00dclikoolist. \u00abKuigi kakaoekstrakt ei asenda tervislikku eluviisi, on need tulemused julgustavad ja toovad esile ekstrakti potentsiaalse rolli p\u00f5letiku reguleerimisel vananedes.\u00bb<\/p>\n","protected":false},"excerpt":{"rendered":"Teadlased tuginesid varasematele avastustele, mis n\u00e4itasid, et flavanoolirikkad toidud ja joogid \u2013 n\u00e4iteks \u0161okolaad, roheline tee, \u00f5unad ja…\n","protected":false},"author":2,"featured_media":54786,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[80],"tags":[26,27,37,33,35,34,36,31,32,27881,27880,21,18913,27876,11709,9763,28,29,95,19,7935,27878,27877,25,9764,14009,23,24,22,20,7514,27879,30,92,93,94],"class_list":{"0":"post-54785","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-maailm","8":"tag-breaking-news","9":"tag-breakingnews","10":"tag-ee","11":"tag-eesti","12":"tag-eesti-keel","13":"tag-estonia","14":"tag-estonian","15":"tag-featured-news","16":"tag-featurednews","17":"tag-flavanoolid","18":"tag-flavonoidid","19":"tag-headlines","20":"tag-immuunsus","21":"tag-immuunsuse-tugevdajad","22":"tag-immuunsusteem","23":"tag-kakao","24":"tag-latest-news","25":"tag-latestnews","26":"tag-maailm","27":"tag-news","28":"tag-poletik","29":"tag-poletik-organismis","30":"tag-poletikuvastane","31":"tag-populaarseimad-lood","32":"tag-sokolaad","33":"tag-sudame-veresoonkonna-haigused","34":"tag-top-stories","35":"tag-topstories","36":"tag-uldised-uudised","37":"tag-uudised","38":"tag-vananemine","39":"tag-vananemisvastane","40":"tag-viimased-uudised","41":"tag-world","42":"tag-world-news","43":"tag-worldnews"},"share_on_mastodon":{"url":"","error":"Validation failed: Text character limit of 500 exceeded"},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/posts\/54785","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/comments?post=54785"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/posts\/54785\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/media\/54786"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/media?parent=54785"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/categories?post=54785"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ee\/wp-json\/wp\/v2\/tags?post=54785"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
