Ukubonakala kwe-vithamine ilanga kudlala indima kumsebenzi womzimba womntu
I-Vitamin D isebenze imisebenzi ebalulekileyo ye-immune system. Ngokomzekelo, iyakwenza ukuvuselela isistim somzimba ngokuchasene nezifo ezahlukeneyo ezifana nesifo sofuba kwaye kunokunceda ukukhusela iintlobo ezithile zesifo somhlaza, okanye izifo ezithintekayo njenge- multiple sclerosis (nangona kunjalo konke kusekufundiswa).
Ukongezelela, uphando lubonisa ukuba i-vitamin D inokudlala indima ebalulekileyo ekuthintekeni kwezifo ezahlukahlukeneyo.
Yintoni Ikhonkco Phakathi Kwenyuka Kwezilwanyana Ne-Vitamin D?
Izifo ezithintekayo eziphantse kuzo zonke iindidi, kuquka i- asthma , i -rhinitis ye-allergen , i- allergies yokutya , i- eczema , kunye ne- anaphylaxis sele ixhaphake kakhulu kwiminyaka embalwa edluleyo. Oku kunokuba kuchazwe ngokucacileyo ngengqondo yezempilo , kodwa ezinye iingcali zicinga ukuba oku kuhambelana nokusilela kwe-vitamin D.
Ukuxhasa le ngqamaniso, ubungqina besayensi bubonisa ukuba i-anaphylaxis kwizinto ezibangelwayo ezahlukeneyo (ezifana nokutya, amayeza kunye nezilwanyana ezinambuzane) zenzeka kumazinga aphezulu kakhulu kwiindawo ezinokungabikho kwelanga elingaphantsi (kwiindawo ezisenyakatho).
Ukongezelela, i-asthma, i-eczema, kunye ne- atopy zidibaniswe namazinga aphantsi e-vitamin D, ngokukodwa kubantu abaguqulwe kwii-genetic receptor. Kwakhona, i-vitamin D eyongezelelweyo enikezelwa kwabasetyhini abakhulelweyo yanciphisa kakhulu ukuvela kwesifo se-asthma nezinye izifo ezithintekayo kubantwana abancinci.
Ukongezelela, uphando lubonisa ukuba i-vitamin D inokuqalisa ukusebenza kwamaseli e-immune alawulayo okukhusela ukukhutshwa kweekhemikhali ezibangela ukonakalisa izifo ezikhuselweyo.
Ngoko ukungabikho kwe-vitamin D, kunokunqanda le ndlela yokulawula, ekhokelela ekubandezelweni kwezifo ezibangelwa yizilwanyana ezibangelwa zizifo, okanye nokuba yintlungu yesifo esichaphazelekayo.
Oku kuthethwa konke, kubalulekile ukuba ungagqitheli-lula lula ukuphuhliswa kwezifo, kubandakanya izifo ezigugu, ezinokuthi zinkimbinkimbi, ezibandakanya zombini izityalo kunye neendawo eziphilayo.
Esikhundleni saloo mfanekiso mkhulu apha, ukuba u-vitamin D ukusilela kunokudlala indima kumntu, kodwa nangona kunjalo, kushiya iingcali ezikhanda iintloko.
Kutheni Kukhona Ukuntula Kwevithamini D?
Uphando oluninzi lubonisa ukuba ukukhubazeka kwe-vitamin D kuxhaphake kakhulu, kungekhona kwinqanaba elithintekayo kwi-bone (impilo ye-vitamin D ikhusela izifo zethambo njenge-rickets kunye ne-osteomalacia), kodwa kwindlela izinga le-immune elichaphazeleka ngayo.
Izizathu zokunqongophala kwe-vitamin D kwiindawo ezahlukileyo aziqondi ngokupheleleyo. Abaphengululi abaninzi bathi i-vitamin D ayinako ukuphila kwimihla ngemihla ebandakanya ixesha elithengiweyo ngaphakathi kwindlu engenakho ukukhanya kwelanga, kunye nokusetyenziswa kwe-sunscreen (ngenxa yengxaki yomhlaza wesikhumba). Khumbula, i-vitamin D yenziwa elukhumbeni ngokukhanya kwelanga-ukuze i-sunscreen kunye nendlela yokuphila yangaphakathi izakukhusela ukuveliswa kwe-vitamin D.
Ukutya kunokufumana enye inkcazo yokungabikho. I-Vitamin D ibaluleke kakhulu kwisondlo kodwa ifunyanwe ngokwemvelo ngokutya okumbalwa (umzekelo, intlanzi enamafutha, ioli yesibindi, ii-yolk). Oko kuthethwa, ukutya okuninzi kuqiniswe nge-vitamin D, kubandakanywa ukutya okusasa kwasekuseni, ubisi kunye nezinye iimveliso zobisi.
Sekunjalo, nangona isithintelo, abaninzi abantu abafumani ngokwaneleyo i-vitamin D.
Ingakanani i-Vitamin D Ngaba Uyayifuna?
Ayaziwa kakuhle kangakanani i-vitamin D efunekayo ekusebenzeni kakuhle kwe-immune, kodwa abaninzi abantu kumazwe athuthukile bafumana i-vitamin D eyaneleyo yamathambo enempilo.
Nangona kusekho impikiswano phakathi kweengcali malunga nokuba i-vitamin D yenzani, emva kokuphonononga uphando kwi-vitamin D, i-Institute of Medicine yabika ukuba uninzi lwabantu lunamanqanaba aneleyo e-vitamin D xa i-25 (OH) D nqanaba ( oku kuvavanyo olulula lwegazi) lukhulu kunokuba lilingana no-20ng / mL. Abantu abaninzi abasengozini yokunqongophala kwe-vitamin D xa amazinga angaphantsi kwama-12ng / mL.
Ukuxhaswa nge-vitamin D, nangona kunjalo, kubanzi kunzima, njengomgangatho womntu ngamnye, kwaye banokufunwa kangakanani imihla ngemihla ukugcina isilinganiselo se-vitamin D eqhelekileyo kuxhomekeke kwizinto ezininzi. Ezi zinto ziquka:
- umbala wesikhumba
- ukukhanya kwelanga
- ukutya
- nokuba umntu unayo nayiphi na ingxaki yonyango (umzekelo, isibindi okanye isifo sesifo).
Ukongezelela, kunokwenzeka ukudlula i-vitamin D, kunye nefuthe eliphambili leentsimbi zeentso , ngoko kubalulekile ukuthetha nodokotela wakho ngaphambi kokuthatha nayiphi na isongezelelo se-vitamin D. Kwakhona, ngelixa ukucoca iibhedi kunye nokutshatyalaliswa kwelanga ngokugqithisileyo akukhuthazwa ukuba ufumane i-vitamin D eyaneleyo ngenxa yengozi yomhlaza wesikhumba , imali encinci yokutshatyalaliswa ilungile, njengemizuzu engama-15 ngemini iintsuku ezimbini ukuya kwethathu ngeveki (njengoko kucetyiswa ngabanye ngcali).
