Cishe uzwe ngokubaluleka kwe-vitamin D nokuthi ochwepheshe bezempilo abaningi batusa ukuthi uthole okuningi kwalolu vhamini obalulekile. Ngokuyinhloko, ukuhlolwa nokuxhaswa nge-vitamin D kuye kwanconywa ngokuphindaphindiwe ngeziguli ze- thyroid, autoimmune, kanye nokukhuluphala.
Kodwa yini ukucabanga nesayensi kulezi zincomo?
Ngathola ithuba lokuba ne-Q & A emfushane noRichard Shames, MD-udokotela osebenzayo, umbhali wenani lezincwadi ezithandwayo ezifweni zegciwane, nomqeqeshi we-thyroid-ngesihloko sokuthi kungani ebheka i-vitamin D ebaluleke kangaka iziguli ze-thyroid.
1. Kungani uzizwa u-vitamin D kubaluleke kakhulu kubantu abanezimo ze-thyroid?
URichard Shames, MD: Lo vithamini obaluleke kakhulu emsebenzini we -roid ukuthi isimo sawo manje sesiphakanyiswe ngabacwaningi ukuba basebenzise i-hormone noma i-pro-hormone. Manje sisazi ukuthi ukuhlukahluka kwe-thyroid ukusebenza noma ukungasebenzi emzimbeni wakho kuxhomeke ekubeni khona kwevithamini D, okwenza ukuthi kungabi nje inzuzo, kodwa kubaluleke kakhulu empilweni ye -roid.
2. Uphi i-vitamin D ehambisana nayo, ngokuqondene nezinye izakhi ezingasetshenziswa empilweni ye-thyroid, isibonelo, selenium, ithusi, ne-zinc, kanye nezindaba ezifana nokugwema ubisi obuningi nokulinganisela i-iodine ?
URichard Shames, MD: Muva nje ngangiqeqesha isineke esiqaphile futhi sinembeza nge-hypothyroidism.
Wayethatha inani elikhulu lamaminerali asanda kukhulunywa ngawo; futhi ngaphezu kwalokho, wayethatha imithi yokwelapha ukukhuthaza impilo yakhe ye-thyroid, kanye nokukhulelwa kwe-pro-hormone, ukwandisa ukutholakala kwe-hormonecortisol ye-adrenal. Ngaphezu kwalokho, wayethatha imithi yokwelapha yegciwane , ehlanganisa inhlanganisela ye- T4 / T3 , enezinhlobo ezincane zemvelo ye-thyroid ephelele.
Ngisho nayo yonke le mzamo, wayengatholi imiphumela emihle ngokwemibandela yokuphumula kwesifo. Ngemuva kokuhlola izinga lakhe le-vitamin D, ngithole ukuthi lisezingeni eliphansi elijwayelekile, futhi salikhulisa kuze kube sezingeni eliphakathi kuya phezulu. Khona-ke waqala ukwenza kahle.
3. Ucabanga ukuthi kungani lokhu kusebenza?
URichard Shames, MD: Ukwelashwa kwe-thyroid akuyona into ehle-futhi kungenzeka kungasebenzi-uma ungenayo i-vitamin D eyaneleyo yesinyathelo sokugcina esiyinkimbinkimbi, esenzeka esiteshini lapho i-hormone yegciwane esebenza ngempela. Lokhu kwenzeka ngaphakathi kwe-nucleus yeseli. I-Vitamin D idinga ukuba khona emazingeni anele esitokisini ukuze i-hormone yegciwane ithinte ngempela leyo cell. Yingakho i-vitamin D ibaluleke kangaka.
4. Ingabe sithola uvithamini D ngokwanele kusuka ekushiseni kwelanga noma multivitamini, noma kudingeka sidinge?
URichard Shames, MD: Lezi zinsuku abantu basebenzisa ama-sunblocks, futhi bahlala ngaphakathi besebenza emakhompyutheni abo kaningi. Ngakho-ke, sithola i-vitamin D engaphansi kwelanga. Ngaphezu kwalokho, ama-multivitamines ngokuvamile ane-400 IU ye-Vitamin D, eyayiyisilinganiso se-RDA kusukela ocwaningweni olwenziwa emuva ngawo-1940 no-1950. Namuhla, lolu cwaningo lubuzwa, nabacwaningi abaningi manje bancoma ubuncane bezinkulungwane ezingu-1 000 kuya ku-2,000 IU nsuku zonke, inani elide kakhulu kunalokho okutholakala kuma-multivitamini amaningi.
Kule ndaba ngenhla, isibonelo, isiguli sami sidinga 4,000 nsuku zonke i-IU ukuze kufeze imiphumela yakhe emihle.
5. I-vitamin D ingahlolwa kanjani?
URichard Shames, MD: Ngikholelwa ukuthi ukuhlolwa kwegazi ku-vitamin D kubalulekile kunoma ubani osebenzelana ne- hypothyroidism . Uhlobo oluvamile lwamanqanaba e-vitamin D luvela ku-30 kuya kwezingu-100. Khumbula ukuthi nje ukuphela komkhawulo ojwayelekile ojwayelekile ngeke wenze umsebenzi owanele kumuntu onesifo se-thyroid esingasebenzi. Iziguli ze-Thyroid zidinga ukuba "zigcwale" -kusho lokho okungenani izinga elingama-50-60, noma ngaphezulu.
6. Uma uphansi noma ophansi, ukhona uhlobo oluthile lwevithamini D oyincomayo?
Richard Shames, MD: Qinisekisa ukuthi i-vitamin D3.
Ngivame ukuncoma ukuthi iziguli zami zithathe okungenani u-2 000 IU ngosuku ngosuku lwesondlo, 4,000 ngosuku uma ziphela ekupheleni kwezinga eliphansi, futhi 6,000 ngosuku uma ukuhlolwa kwabo kubonisa amazinga e-vitamin D ngezansi evamile. Ngivame ukuncoma iziguli ezongezelayo izinyanga ezimbili kuya kwezintathu, bese uthola ukubuyiselwa ukuhlola ukuthuthukiswa. Ngivame ukuba neziguli ezihamba phansi noma ezisezingeni eliphansi ukuya emzimbeni wesondlo we-I-2,000 uma amazinga egazi esefinyelele ku-50 kuya ku-60 noma ngaphezulu.
