Kaj je vanadij?<\/h2>\n

Vanadij je element v sledeh, kar pomeni, da ga v telesu najdemo v majhnih koli\u010dinah. Ta mineral je klju\u010dnega pomena za normalno rast kosti, \u010deprav dosedanje \u0161tudije niso mogle natan\u010dno dolo\u010diti, kak\u0161ne u\u010dinke ima lahko vanadij ali katera koli\u010dina vnosa je najprimernej\u0161a. Vanadija ne priporo\u010damo osebam, ki imajo kakr\u0161no koli bolezensko stanje; lahko pa vpliva na krvni sladkor pri osebah s sladkorno boleznijo.<\/p>\n

 <\/p>\n

Kak\u0161na je funkcija vanadija?<\/h2>\n

Vanadij je pomemben za rast in razvoj organizma. Pomembno vlogo ima natrijeva-kalijeva \u010drpalka, ionska \u010drpalka, ki se nahaja v celi\u010dni membrani in sodeluje pri proizvodnji encimov. Proizvodnja encima vklju\u010duje presnovo hranil, hormonov in kostnega tkiva, pa tudi zavira sintezo holesterola. Nekatere raziskave ka\u017eejo na to da lahko vanadij igra podobno vlogo kot inzulin, saj pomaga pove\u010dati u\u010dinke hormona in zni\u017eati raven sladkorja v krvi. Vanadij se v\u010dasih ogla\u0161uje tudi kot \u0161portni prehranski dodatek, \u010deprav ni dokazov, ki bi podpirali ve\u010djo u\u010dinkovitost.<\/p>\n

<\/h2>\n

Katera \u017eivila so bogata z vanadijem?<\/h2>\n

Najbolj\u0161i viri vanadija so gobe, \u0161koljke, \u010drni poper, peter\u0161ilj, koper, pivo, vino, \u017eita in \u017eitni izdelki ter umetno sladkane pija\u010de. Obstaja v ve\u010d oblikah, med njimi vanadij sulfat (prehranska dopolnila) in vanadat.<\/p>\n

 <\/p>\n

Kak\u0161ne so priporo\u010dene dnevne potrebe po vanadiju?<\/h2>\n

Priporo\u010deni dnevni vnos vanadija je 10\u201320 mikrogramov. Ve\u010dji odmerki so lahko strupeni. Posamezniki, ki ne smejo jemati vanadija, vklju\u010dujejo \u017eenske, ki so nose\u010de ali dojijo, ter posamezniki z boleznijo ledvic. Dolo\u010deni zapleti, ki se lahko pojavijo, vklju\u010dujejo po\u0161kodbe ledvic, po\u0161kodbe jeter, zmanj\u0161ano plodnost, prirojene okvare in drugo.<\/p>\n

 <\/p>\n

Kak\u0161ne so posledice pomanjkanja vanadija?<\/h2>\n

\u0160tudije na \u017eivalih ka\u017eejo, da bi lahko pomanjkanje vanadija upo\u010dasnilo rast, ustvarilo te\u017eave, povezane z razmno\u017eevanjem (vklju\u010dno z neplodnostjo) in spremenilo raven holesterola, trigliceridov, glukoze in inzulina v krvi. Tudi nezadostna raven tega minerala je lahko povezana s sladkorno boleznijo, sr\u010dno-\u017eilnimi boleznimi in debelostjo. Ker lahko vanadij zni\u017ea raven sladkorja v krvi, lahko posamezniki, ki jemljejo tudi zdravila za zni\u017eevanje krvnega sladkorja, tvegajo razvoj hipoglikemije ali nizkega krvnega sladkorja. Noben od teh u\u010dinkov pa ni zagotovljen in se je treba posvetovati z zdravnikom zaradi mo\u017enih stranskih u\u010dinkov in zapletov.<\/p>\n

 <\/p>\n

Kak\u0161ne so posledice prekomernega vnosa vanadija?<\/h2>\n

Prekomerni vnos vanadija nad 10 mg na dan je domnevno strupen in lahko povzro\u010di zaplete, kot so po\u0161kodbe jeter ali ledvic, pa tudi ve\u010dje tveganje za nastanek raka dojke. Na splo\u0161no velja da, \u010de je vi\u0161je kot oksidacijsko stanje vanadija, bolj strupena je spojina.<\/p>\n","protected":false},"author":11,"featured_media":0,"template":"","yoast_head":"\nVanadij - Humanitas.net<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.humanitas.net\/sl\/diseases\/vanadij\/\" \/>\n<meta property=\"og:locale\" content=\"sl_SI\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Vanadij - Humanitas.net\" \/>\n<meta property=\"og:description\" content=\"Kaj je vanadij?
