Zvechokwadi, mavhitamini ose anokosha kumatumbu. Nekudaro, imwe vhitamini inowanzoshomeka asi inganyanya kunaka kune maruva emukati. Naizvozvo, ita shuwa kuti une kupihwa kwakanaka kwevhitamini iyi!
Kuti vhitamini D inogona sei kudzora maruva emukati
Iyo iri kure kwaunogara kubva kuequator, iyo shoma UV mwaranzi inosvika pasi uye inowedzera njodzi yekutambura nekushomeka kwevhitamini D. Ngozi yezvirwere zvisingaperi inowedzera, zvakadai senjodzi yemultiple sclerosis kana zvirwere zvisingaperi zvinoputika.
Nekudaro, isu tinoziva kuti mamiriro emudumbu maruva anoitawo basa rakakosha mukukura kweichi uye zvimwe zvakawanda zvirwere zvisingaperi. Pane hukama here pakati pezinga revhitamini D uye mamiriro emaruva emukati? Zvingave zvakakwana here kuunza iyo vhitamini D level kumusoro? Uye vhitamini D yaizobva yagadzirisa maruva emukati?
Kuti tipindure mibvunzo iyi, boka revatsvakurudzi vepaUniversity of British Columbia, kuVancouver, Canada, rakaongorora kuti maruva emudumbu anoita sei kumwaranzi yeUV. Chidzidzo ichi chakaburitswa muFrontiers mumagazini yeMicrobiology.
Mwaranzi yeUVB inowedzera vhitamini D mazinga - kunyangwe pakanga paine kushomeka kusati kwaitika kana kwete
Vakadzi 21 vakatora chikamu muchidzidzo ichi - vese vane ganda rakatsetseka kubva kuI kusvika kuIII (maererano neFitzpatrick). Vapfumbamwe vakatora vhitamini D yekuwedzera mumwedzi mitatu isati yatanga chidzidzo uye vakazova nehutano hwevhitamini D. Vatori vechikamu gumi nevaviri vakasara vanga vasingatore vhitamini D yekuwedzera uye vese kunze kwemumwechete vatori vechikamu vaive vasina vhitamini D.
Vese vakaedzwa vakagamuchira matatu-muviri-waradhi nemwaranzi yeUVB mukati mesvondo, kureva mwaranzi iyo (kusiyana nemwaranzi yeUVA) inokonzeresa kuumbwa kwevhitamini D. Vitamin D mazinga akawedzera mune vese vatori vechikamu, vangave vakambove nemazinga asina kukwana kana kwete.
Mwaranzi yeUVB inowedzera kusiyanisa kwemaruva emukati
Vesainzi vakabva vaenzanisa kuti mwaranzi yakanga yachinja sei maruva emukati mevakadzi. Zvakaonekwa kuti shanduko mumaruva emudumbu yainyanya kuoneka zvakanyanya kutaurwa kushaikwa kwevhitamini D kwaive pakutanga kwechidzidzo.
"Vasati varatidzwa UVB, vakadzi vane vhitamini D kushomeka vaive nemafuta mashoma, ane mashoma akasiyana, pane vakadzi vaigara vachitora vhitamini D," akadaro munyori wekudzidza Purofesa Bruce Vallance.
Chiedza cheUVB chaive zvino chakwanisa kushandura nekuvandudza maruva emudumbu evakadzi vakambotambura nekushaikwa kwevhitamini D nenzira yekuti hapana mutsauko mumhando yemaruva emudumbu erimwe boka revatori vechikamu (vakange vatora vhitamini D kugadzirira. ) zvaigona kuonekwa.
Zvaifadza zvakare kuti maruva emudumbu eavo vatori vechikamu vakanga vasati vambove nekushaya vhitamini D haisati yachinja nekuda kwemwaranzi. Huru hwemudumbu hune hutano hunogona kukanganiswa nekuwedzera kwevhitamini D (muchimiro chemwaranzi yeUVB yakawanda), izvo zvinoratidza kuti hapana shanduko dzisina kunaka pakutya.
Mushure mevhiki imwe chete, maruva emukati anoshanduka
Mutungamiriri weChidzidzo Else Bosman akatsanangura kuti: "Takaona muongororo yedu kuti vhitamini D ndiyo inonyanya kufambisa maruva emukati, kuitira kuti chiedza chezuva, chinotungamira kukugadzirwa kwevhitamini D muganda, chakakosha pahutano hwematumbo."
“Chinonyanya kufadza pakudzidza kwedu ndechokuti unogona kutoona migumisiro iri pachena pashure pevhiki imwe chete yechidzidzo chacho,” anodaro Bosman. Nekudaro, marambi akakosha akashandiswa muchidzidzo, ayo anoburitsa mwaranzi yeUVB kunyanya, kureva kuti haigone kukonzera kupisa kwezuva, saka nguva yekubuda kubva muchidzidzo haigone kushandiswa pakutsva nezuva mune ramangwana.
Kugeza nezuva kana vhitamini D zvinowedzera?
Sekare, kupisa kwezuva kunofanirwa kuchinjirwa kune yega ganda rudzi, nguva yezuva, mwaka, uye latitude kuti uwane nguva yenguva inokwana kukwirisa vhitamini D, asi panguva imwe chete haikonzeri. kutsva nezuva.
Munguva yechando uye neganda rinonyanya kuoma zvakare muzhizha, zviri nani kuvimba nevhitamini D yekuwedzera. Nekuti chikafu chega hachiwanzopa vhitamini D yakakwana.
Sezvo chidzidzo ichi chakaitwa nevanhukadzi, vane ganda rakapfava, uye vane hutano, kumwe kuferefetwa kwaizofanira kuitwa nemamwe (uyezve nemapoka makuru) ezvidzidzo zvekuyedzwa, sevanhu vane ganda dema uye zvakare. nevaya vanototambura nezvirwere zvisingaperi, anodaro Bosman. Nekuti ipapo zvinogona kuratidzwa kana vanhu vanorwara nekuzvimba kwematumbo, semuenzaniso, vanogona kubatsirwa neUVB radiation therapy.
Aya ndiwo magadzirirwo aunoita vhitamini D yako uye panguva imwechete kudzorera maruva ako emukati
Zvidzidzo zvechidzidzo zvinowanzo shandiswa kugadzira marapirwo matsva ekurapa. Asi kazhinji - uye ndizvo zvazvakaita muchidzidzo chazvino - munhu anogonawo kutora matanho ekuzvibatsira kubva pane izvi:
- Kubva kwatiri (ZDG) maonero, imwe nzira kune yakaongororwa UVB mwaranzi ingangove yekuyambira avo vakabatwa (uye zvechokwadi vanachiremba vavo) kuti vaise mbiru ZVIBVIRI mukurapa kwechirwere, nekuti chokwadi kwete chete vhitamini D inokanganisa intestinal flora:
- Chekutanga, ita shuwa kuti une vhitamini D yakakwana, kureva kuti unogara uchinakidzwa nekutsva nezuva uye/kana kushandisa zvemhando yepamusoro vhitamini D zvinowedzera uye.
chechipiri, shandisa zviyero zvemaruva ane hutano hwematumbo, semuenzaniso B. kudzidzira kudya kwakakodzera kwemaruva emukati, kutora probiotics, nezvimwewo.
