Du leidest an Vitamin A-Mangel? Hier sind 20 Lebensmittel die helfen können!

Vitamin A ist ein fettlösliches Vitamin, das eine wesentliche Rolle bei der Erhaltung von Sehkraft, Körperwachstum, Immunfunktion und reproduktive Gesundheit spielt. Erste eine ausreichende Menge an Vitamin A sollten die Symptome des Mangels wie Haarausfall, Hautprobleme, trockene Augen, Nachtblindheit und erhöhte Anfälligkeit für Infektionen verhindern. Bestenfalls sollte dies durch eine ausgewogene Ernährung kommen.

Der Vitamin A-Mangel ist eine der Hauptursachen für Blindheit in Entwicklungsländern. Im Gegensatz dazu bekommen die meisten Menschen in den entwickelten Ländern genug Vitamin A durch die vielseitige Ernährung. Jedoch sollte man das Thema nicht zu leichtnehmen, da bereits auch geringe Mangelerscheinungen eine negative Auswirkung auf unseren Körper haben.

Die empfohlene Nahrungsergänzung (RDA) ist 900 mcg für Männer, 700 mcg für Frauen und 300-600 mcg für Kinder und Jugendliche. Die RDA bietet genug Vitamin A für die überwiegende Mehrheit der Menschen. Einfach ausgedrückt wird ein einziger Tageswert (DV) von 900 mcg als Referenz auf Nährwertschriften in den USA und Kanada verwendet.

Bezugnehmend auf diesen Messwert beschäftigt sich dieser Artikel mit 20 Lebensmittel, die reich an Vitamin A sind, plus zusätzliche 20 Früchte und Gemüse reich an Provitamin A sind.

10 Gemüse die reich an Provitamin A sind

Doch tierische Lebensmittel sind nicht die einzigen Quellen um Vitamin A zu beziehen. Der Körper kann Vitamin A aus Carotinoiden in Pflanzen produzieren. Diese Carotinoide umfassen Beta-Carotin und Alpha-Carotin, die zusammen als Provitamin A bekannt sind. Allerdings tragen etwa 45% der Menschen eine genetische Mutation in sich, die ihre Fähigkeit, Provitamin A in Vitamin A umzuwandeln, deutlich reduziert.

Abhängig von der Genetik, könnte das folgende Gemüse erheblich weniger Vitamin A als angegeben erhalten.

Welche Voraussetzungen gibt es für die Aufnahme von Vitamin A?

Sie können ganz einfach Ihren Bedarf für Vitamin A durch regelmäßiges verzehren einiger der in diesem Artikel aufgeführten Lebensmittel. Viele Lebensmittel enthalten auch Vitamin A, einschließlich Getreide, Margarine und Milchprodukte. Da Vitamin A fettlöslich ist, wird es effizienter in den Blutkreislauf aufgenommen, wenn es mit Fett gegessen wird. Die meisten tierischen Lebensmittel, die reich an Vitamin A sind haben meist auch einen hohen Fettgehalt. Jedoch gilt Gleiches nicht für die meisten pflanzlichen Quellen von Provitamin A. Sie können Ihre Aufnahme von Provitamin A aus pflanzlichen Quellen verbessern, indem Sie einen Schuss Öl zu Ihrem Salat hinzufügen. Allerdings haben, wie oben erwähnt, einige Leute eine genetische Mutation, die die Umwandlung von Provitamin A in Vitamin A viel weniger effizient macht. Aus diesem Grund sollten Veganer Ergänzungen nehmen oder sicherstellen, viel von den oben aufgeführten Früchten und Gemüse zu essen. Glücklicherweise sind Lebensmittel die reichhaltig an Vitamin A sind in der Regel leicht zu bekommen und die meisten sind eine hervorragende Ergänzung zu einer gesunden Ernährung.

    Today, I went to the beachfront with my children. I found a sea shell and gave it to my 4 year old daughter and said
    “You can hear the ocean if you put this to your ear.” She put the
    shell to her ear and screamed. There was a hermit crab inside and it pinched
    her ear. She never wants to go back! LoL I know this is totally off topic but I had to tell
    someone!
