Zvingaita sezvisinganzwisisiki kusimudzira kukosha kwevhithamini D kana chiri chirimo, asi vazhinji vedu ticharamba tichida kubatsiridza pasinei nekuwanda kwemwaka. Kana mazamu ako ari pasi, rimwe chete kana maviri vhiki yezororo pamhenderekedzo yegungwa zvichida hazvikwanisi kuunzazve vitamini ichi kuti iwane. Uye, kana ukashanda mudzimba kana kupfeka ganda rezuva rechitendero kana uchienda panze (uye zvakanaka kwauri kana iwe uchiita), unofanira kunge uchiwedzera pamwe ne vitamini D.
Pamusoro pemigumisiro inobatsira pamapfupa eutema uye calcium kudya, vitamini D inopa simba rekuchengetedzwa kwekenza. Zvimwe zvezvakawanikwa zvakanyanya-pasi mune zvekudya kwekudya mumakore achangopfuura ave uchapupu hwokuti vitamini D inokwanisa kudzivirirwa nekenza. Mamwe mapepa emasayenzi anopfuura 800 ave akabudiswa pahukama pakati pevhitamini D nekenza. Isu iye zvino tine uchapupu hwakakwana hwokuti kuchengetedza zvakakwana mavhitamini D mazinga ndiyo nzira inobatsira yekuchengetedza kenza. Kutsvakurudza kunoratidza kuti vitamini D yakakwana inoderedza ngozi yorufu mumucheche, mairare, mapapu uye kenza ye prostate, leukemia uye lymphomas uye makondombera ose akabatanidzwa. A 2014 kuongororwa kwe vitamini D kuwedzera kwakawanikwa kuti yakabatanidzwa nehuwandu hwekufa kwekenza.
Uchapupu hwehutano hweWitamin D yekuderedza kano kanopera
Iko pfungwa yokuti vitamin D inogona kudzivirira pakirwere yekenza inotangira kubva pakucherechedza kuti kufa kwekenza yekoloni kwaive kwakakwirira kune dzimwe nzvimbo dzisina chiedza chezuva.
Tsvakurudzo dzinoverengeka dzakawana hukama hwepakati pakati pekudzivirira kwezuva uye 24 marudzi akasiyana ekenza, kusanganisira mamwe anozivikanwa-mazamu, colon, rectum, uye prostate. Nemhaka yekuti vanhu vazhinji vevhitamidzi D vanobva kune chiedza chezuva, uye ganda rakasviba harina kubudirira pakubudisa mavhitamini mukupindura mazai eV, mararamiro eV vitamin D inofungidzirwa kuti ndeimwe chikonzero chekuparara kwekenza kunovapo pakati peAfrica Americans neVaMerica.
Uchapupu hunoti kuve nehuwandu hwevhitamin D's mukuderedza kenza yekenza kwawedzera kukura. Kuwedzera kwekusimbisa kukosha kwevhitamin D's mukudzivirira kenza mutsara kwakapiwa nemaedzo anorongwa nemaitiro e vitamin D supplementation iyo yakaratidza kuderedzwa kwechirwere chekenza zvichienzaniswa ne placebo. Ikoko kunewo mimwe mizhinji iyo vitamini D inotor gene genetic mutations, iyo inopesana nezviito zvezvakaberekwa zvechiito zve vitamini D, zvakabatanidzwa nehuwandu hwekenza yakawanda.
Zvimwe zvidzidzo zvakatsigira kuti vitamini D inogona kudzivirira kenza yemukiramu kukura munzira dzakawanda: Vitamin D inoshandura kutaura kwemajini anoshandura kurwisa, sero kufa uye kushandiswa kwesero, uyewo kunopesana nezviito zvinokurudzira-kukurudzira IGF-1 nezvimwe kukura zvinhu. Inowedzerawo kugadzirisa DNA uye kudzivirirwa kwezvirwere, uye angiogenesis inhibition.
Vitamin D uye Utano Hwehutano
Mukuwedzera pakudzivirira kenza, kuve nechokwadi kuti mavhitamini D mazinga akakwana anogona kubatsira kuderedza dambudziko rekukanganisa nekuwira. Kupora kunogona kuparadza vanhu vakwegura, chinokonzera kuputsika, kukuvadzwa kwepamusoro , nekufa kwechiitiko kune vanhu vakwegura. Mushure mekuwa, zvinowanzoita kuti munhu akwegura ave nekukurumidza kunonoka kwekuita basa uye kurasikirwa kwekusununguka.
Inenge 25 muzana yevanhu vekuAmerica vakwegura vanowa vanofa mumwedzi mitanhatu, uye vanopfuura 50 muzana vanobudiswa kumusha wakwegura.
Kurasikirwa kwemasisita mashoma uye kushayikwa kwevhithamini D kune mbiri dzezvipingamupinyi zvekuwira, uye izvi zvinosangana. Chimwe chevhitamin D's chiduku chinonyanya kuzivikanwa ndiyo inobatsira pamusana pemaitiro, nekuchinja mararamiro ekutaura uye calcium kutakura mumasero emasumbu. Low vitamin D inobatanidza nekuderedza simba musimba kune vakwegura, uye vitamini D supplementation yakawanikwa kuvandudza simba remasimba uye kuenzanisa.
Kusarudza Zvakakwana Mavitamini D
Borderline low mavitamini D akawanikwa akawanikwa zvikuru muUnited States neCanada.
Zvishomanana zvekudya zvinowanzova nemavitamini D uye kuwana mazinga akakwana kuburikidza nezuva kunogona kuva kwakaoma, zvichienderana nekunogara kupi, nguva yakashandiswa kunze, uye ganda rako. Kunyanya kubuda kwezuva kune ngozi yekuparara kweganda uye njodzi yekenza yenguruve.
Nhamba yezuva rimwechete ye vitamine D3 supplement (iyo inowanzoita mavitamini uye ndiyo yakachengeteka, yakakwirira-yepamusoro yehuwandu kupfuura vitamini D2), isarudzo yakangwara kune vanhu vakawanda. Sezvinoratidzwa neuchapupu hwezvesayenzi, chinangwa chekuwedzera ropa re 30 kusvika 45 ng / ml. Kune vanhu vakawanda, izvi zvinoreva kureva pamwe ne1000 kusvika muna 2000 IUs a vitamin D zuva rega rega.
