Avantages importants de la vitamine K pour le corps, la coagulation sanguine et la sant\u00e9 des os<\/span><\/span><\/span><\/span><\/p>\n

 <\/p>\n

Faits sur la vitamine K<\/span><\/span><\/span><\/span><\/h2>\n
    \n
  • Le corps a besoin de vitamine K pour produire de la prothrombine, un facteur de coagulation vasculaire important pour la coagulation du sang et le m\u00e9tabolisme osseux, et les personnes qui prennent des anticoagulants tels que la warfarine ou le Coumadin ne devraient pas prendre de vitamine K sans consulter un m\u00e9decin.<\/span><\/span><\/span><\/span><\/li>\n
  • La vitamine K1 ou phylloquinone provient des plantes et est la principale forme de vitamine K dans les aliments. <\/span><\/span><\/span>La vitamine K2, ou m\u00e9naquinone, se trouve dans certains aliments d’origine animale et ferment\u00e9s.<\/span><\/span><\/span><\/span><\/li>\n
  • La phylloquinone, \u00e9galement connue sous le nom de vitamine K1, se trouve dans les plantes et, lorsqu’elle est absorb\u00e9e par les bact\u00e9ries du gros intestin, elle est convertie en vitamine K2, qui est absorb\u00e9e dans l’intestin gr\u00eale et stock\u00e9e dans les tissus adipeux et le foie.<\/span><\/span><\/span><\/span><\/li>\n
  • La carence en vitamine K est rare, mais dans les cas graves, elle peut augmenter le temps de coagulation, provoquant une h\u00e9morragie et des saignements excessifs.<\/span><\/span><\/span><\/span><\/li>\n
  • Une carence en vitamine K est plus susceptible d’affecter les nouveau-n\u00e9s qui ont des probl\u00e8mes de malabsorption dus au syndrome de l’intestin court, \u00e0 la fibrose kystique, \u00e0 la maladie c\u0153liaque ou \u00e0 la colite ulc\u00e9reuse.<\/span><\/span><\/span><\/span><\/li>\n
  • Les nouveau-n\u00e9s re\u00e7oivent g\u00e9n\u00e9ralement une injection de vitamine K pour les prot\u00e9ger des saignements dans le cr\u00e2ne, qui peuvent \u00eatre mortels.<\/span><\/span><\/span><\/span><\/li>\n<\/ul>\n

    Apport ad\u00e9quat recommand\u00e9 de vitamine K :<\/span><\/span><\/span><\/span><\/strong> Selon l’\u00e2ge et le sexe : Les femmes de 19 ans ou plus devraient prendre 90 mcg par jour et les hommes 120 mcg.<\/span><\/span><\/span><\/span><\/p>\n

    Avantages de la vitamine K<\/span><\/span><\/span><\/span><\/h2>\n

    sant\u00e9 des os<\/span><\/span><\/span><\/span><\/h3>\n

    Il semble y avoir un lien entre un faible apport en vitamine K <\/span><\/span><\/span><\/span>et l’ost\u00e9oporose<\/span><\/span><\/span><\/span><\/strong> . Plusieurs \u00e9tudes ont montr\u00e9 que la vitamine K favorise la sant\u00e9 des os, am\u00e9liore la densit\u00e9 osseuse et r\u00e9duit le risque de fractures, mais la recherche n’a pas confirm\u00e9 cela.<\/span><\/span><\/span><\/span><\/p>\n

    Sant\u00e9 psychologique<\/span><\/span><\/span><\/span><\/h3>\n

    Des niveaux \u00e9lev\u00e9s de vitamine K dans le sang ont \u00e9t\u00e9 li\u00e9s \u00e0 une am\u00e9lioration de la m\u00e9moire chez les personnes \u00e2g\u00e9es, et dans une \u00e9tude, les personnes en bonne sant\u00e9 de plus de 70 ans avec des niveaux \u00e9lev\u00e9s de vitamine K1 avaient les performances de m\u00e9moire les plus \u00e9lev\u00e9es.<\/span><\/span><\/span><\/span><\/p>\n

    sant\u00e9 cardiaque<\/span><\/span><\/span><\/span><\/h3>\n

    La vitamine K peut aider \u00e0 maintenir une pression art\u00e9rielle basse en emp\u00eachant la min\u00e9ralisation, car les min\u00e9raux s’accumulent dans les art\u00e8res. <\/span><\/span><\/span>Cela permet au c\u0153ur de pomper le sang dans tout le corps sans entrave.<\/span><\/span><\/span><\/span><\/p>\n

    La min\u00e9ralisation se produit naturellement avec l’\u00e2ge et est un facteur de risque majeur de maladie cardiaque, et il a \u00e9t\u00e9 d\u00e9montr\u00e9 qu’un apport suffisant en vitamine K r\u00e9duisait le risque d’accident vasculaire c\u00e9r\u00e9bral.<\/span><\/span><\/span><\/span><\/p>\n

    Sources de vitamine K<\/span><\/span><\/span><\/span><\/h2>\n

    La vitamine K1 se trouve en grande quantit\u00e9 dans les l\u00e9gumes \u00e0 feuilles vertes comme le chou fris\u00e9 et la bette \u00e0 carde. <\/span><\/span><\/span>D’autres sources sont les huiles v\u00e9g\u00e9tales et certains fruits.<\/span><\/span><\/span><\/span><\/p>\n

    Voici quelques sources alimentaires de vitamine K :<\/span><\/span><\/span><\/span><\/p>\n

      \n
    • persil.<\/span><\/span><\/span><\/span><\/li>\n
    • choux.<\/span><\/span><\/span><\/span><\/li>\n
    • \u00e9pinard;<\/span><\/span><\/span><\/span><\/li>\n
    • L’huile de soja.<\/span><\/span><\/span><\/span><\/li>\n
    • les raisins;<\/span><\/span><\/span><\/span><\/li>\n
    • Oeuf.<\/span><\/span><\/span><\/span><\/li>\n<\/ul>\n

      Dangers d’un exc\u00e8s de vitamine K et d’interactions m\u00e9dicamenteuses<\/span><\/span><\/span><\/span><\/h2>\n

      La vitamine K<\/span><\/span><\/span><\/span><\/strong> peut interagir <\/span><\/span><\/span><\/span>avec de nombreux m\u00e9dicaments courants tels que les anticoagulants, les anticonvulsivants, les antibiotiques, les hypocholest\u00e9rol\u00e9miants et les m\u00e9dicaments amaigrissants.<\/span><\/span><\/span><\/span><\/p>\n

      Les anticoagulants agissent en r\u00e9duisant ou en retardant la capacit\u00e9 de la vitamine K \u00e0 coaguler, et l’augmentation ou la diminution de la quantit\u00e9 de vitamine K peut affecter le mode d’action de ces m\u00e9dicaments.<\/span><\/span><\/span><\/span><\/p>\n

      Les anticonvulsivants, s’ils sont pris pendant la grossesse ou l’allaitement, peuvent augmenter le risque de carence en vitamine K chez le f\u0153tus ou le nouveau-n\u00e9.<\/span><\/span><\/span><\/span><\/p>\n

      Au final, apr\u00e8s avoir connu les bienfaits de la vitamine K, attention \u00e0 ne pas en prendre \u00e0 fortes doses pour ne pas s’exposer aux risques d’exc\u00e8s.<\/span><\/span><\/span><\/span>
