Ngokutsho kophononongo, ukongezwa ngevithamin D kunokucothisa ukuqhubela phambili kohlobo lwe-2 yeswekile. Nangona kunjalo, kuphela kwidosi ephezulu, ngoko ke iidosi ezicetyiswayo eziqhelekileyo azinakunceda.
I-Vitamin D3 iyeka uhlobo lwe-2 yeswekile
Uphononongo olupapashwe ngoJulayi ka-2019 kwiJenali yaseYurophu ye-Endocrinology yabonisa ukuba ukongezwa kokutya kunye (ngokunxulumene) namayeza aphezulu evithamini D3 kunempembelelo eluncedo kwimetabolism yeswekile kangangokuba yakwazi ukumisa ukuqhubeka kwesifo seswekile. Esi siphumo sijongwe ngakumbi kwizigulana ezinesifo seswekile esandulela isifo seswekile nakwizigulana ezisanda kufunyaniswa ukuba zinesifo seswekile.
Ukunqongophala kwe-Vitamin D kunegalelo elikhulu kwisifo seswekile kunokutyeba
Uhlobo lwe-2 yeswekile lusakhula kwaye luxanduva olukhulu - hayi kwizigulana kuphela kodwa nakwiinkqubo zokhathalelo lwempilo. Ukuba esi sifo asihoywa, isifo seswekile sinokukhokelela kwiingxaki ezinzulu ezinjengokonakala kwemithambo-luvo, ukungaboni, nokungaphumeleli kwezintso.
Imiba eqhelekileyo esemngciphekweni yohlobo lwesi-2 seswekile ziimeko zofuzo (oko kukuthi, ukuba isifo seswekile sabaleka entsatsheni) kunye nokutyeba kakhulu. Uxhulumaniso phakathi kwezinga eliphantsi le-vitamin D kunye nomngcipheko okhulayo wesifo sikashukela sele isungulwe.
- IVithamin D ikhusela kwisifo seswekile
Kutheni i-vitamin D ingabonakali impembelelo kwizifundo zangaphambili
Nangona kunjalo, izifundo apho izigulane zesifo seswekile zanikwa i-vitamin D njengesongezelelo sokutya azizange zibonise impumelelo ethile. Oku akumangalisi, kuba uninzi lwezi zifundo umthathi-nxaxheba ngamnye unikwa idosi efanayo (ephantsi kakhulu) yevithamin D ngaphandle kokuthathela ingqalelo inqanaba levithamin D.
Kwabo bathathi-nxaxheba bebekade bengenayo ivithamin D kwaphela, ukunika idosi encinci yevithamin D akunakutshintsha nantoni na. Kwaye kubathathi-nxaxheba ababeswele ivithamin D ngokucacileyo, utshintsho oluncinci mhlawumbi, njengoko iidosi eziqhelekileyo kwiimeko ezininzi ziphantsi kakhulu ukuba zisondele ekusombululeni intsilelo.
Ukongeza, ezi zifundo bezisoloko zenziwa kwizigulana ezinesifo seswekile ixesha elide, kodwa hayi kwizigulana ezinesifo seswekile esandulela isifo seswekile okanye esandula kufunyaniswa ukuba seswekile. Kungenzeka ukuba izifundo ezihambelanayo zazifutshane kakhulu okanye abamakishi abafanelekileyo abazange bahlolwe ukuba babone utshintsho kwi-glucose metabolism.
I-Vitamin D3: I-5000 IU imihla ngemihla iphucula amaxabiso eswekile
UDkt Claudia Gagnon kunye noogxa bakhe baseUniversité Laval eQuebec (Canada) ngoku bavale ngokuchanekileyo lo msantsa. Kuphononongo lwabo, izigulane ezingama-96 ezisanda kufunyaniswa zesifo seswekile okanye izigulane ezine-pre-diabetes zafumana i-5000 IU ye-vitamin D3 okanye i-placebo iinyanga ezintandathu.
Ngenxa yeengcebiso eziqhelekileyo zokungathathi i-vitamin D3 kwiidosi eziphezulu kune-800 ukuya kwi-1000 IU, i-5000 IU ngokuqinisekileyo sele iyidosi ephezulu kakhulu.
I-46 ipesenti yabathathi-nxaxheba baye bafunyanwa ngaphambili ukuba banamanqanaba aphantsi e-vitamin D. Nangona kunjalo, ukuphuculwa kwe-glucose metabolism kunye nokusebenza kwe-pancreatic kunokubonwa phantse kubo bonke abathathi-nxaxheba.
Ukongezwa kokutya kunye ne-vitamin D3 kuphuculwe kakhulu isenzo se-insulin (ubuntununtunu be-insulin) kunye nokwandisa ukusebenza kakuhle kweeseli ze-pancreatic beta (iiseli kwi-pancreas ezivelisa i-insulin). Akukho luphuculo lunjalo lubonwe kwiqela le-placebo.
Soloko uthatha i-vitamin D3 ngabanye - nokuba unesifo seswekile
Ngokuqinisekileyo, akukaziwa ukuba i-vitamin kufuneka ithathwe ngokusisigxina kule dosi ukwenzela ukuzinzisa impumelelo kunye nokuba - ngokutsho kwabaphandi - idosi enjalo ikhuselekile kwaye inempilo kwixesha elide. Ke ngoko, izazinzulu zaziva zinyanzelekile ukuba zibonise ukuba okwangoku umntu kufuneka athathe iidosi ezicetyiswayo ngokusemthethweni de abe azi ngakumbi.
Sisoloko sincoma i-dose ye-vitamin D3 ngokwemeko yomntu ngamnye, ukuba amanqanaba egazi e-vitamin D ahlolwe ngamaxesha aqhelekileyo, kunye nokulungelelanisa umthamo we-vitamin D ngokufanelekileyo ukuze kugcinwe inqanaba elinempilo kwixesha elide.
Oku kunokuthetha, umzekelo, ukuba awuncedi kwaphela ehlotyeni (xa umzimba unokuvelisa ngokwaneleyo ivithamin D ukusuka ekukhanyeni elangeni), kodwa kuphela ekwindla, ebusika nasentwasahlobo.
