Abasetyhini abasetyhini - kwaye ngokukodwa, abafazi abakhulelweyo abaneemeko ze-thyroid - badinga iodine eyongezelelweyo. Iodine iyimfuneko kuba isakhiwo sakhiwo sokwenziwa komzimba wehomoni ye- thyroid . Ngethuba lekota yokuqala yokukhulelwa, xa umntwana engakwazi ukuvelisa i-hormone ye-thyroid, unina uvelisa "i-hormone ye-thyroid". Ukuba akanako iodine eyaneleyo kwinkqubo yakhe, impilo yentsana yakhe - kunye nempilo yakhe - ingabandezeleka ngenxa yokungabikho kwe-hormone eyaneleyo.
Nangona i-iodine engenakho ukukhupha i-United States, iyakhula. Ekupheleni kowama-2006, iKomidi yezeMpilo yoMbutho we-American Thyroid Association (ATA) ikhishwe ingxelo kwingxelo yeTyroid imema bonke abafazi abakhulelweyo ukuba bancedise nge-iodine. Kwaye uvavanyo lukazwelonke luka-2003-2004 lwezeMpilo kunye neZondlo (i-NHANES) lufumene ukuba ngaphezu kwama-37% wabesetyhini abaneminyaka yobudala yokubeletha abanokubaluleka kwe-iodine ukubonisa ukusilela kwe-iodine.
Iinqanaba eziphakanyisiweyo zeIodine
Ukuxhalabisa ngenxa yokuntuleka kwe-iodine ngexesha lokukhulelwa kunye ne-lactation (ukuncelisa ibele) kuye kwaphumela kwimibutho emininzi ekhupha izikhokelo kunye neencomo zokufumana i-iodine. Ngokutsho kweNew England Journal of Medicine (i-NEJM), ezi ziinqununu zokunyuswa kwe-iodine imihla ngemihla ngexesha lokukhulelwa kunye ne-lactation:
- Ukudla kwe-iodine yemihla ngemihla engama-220 μg ngexesha lokukhulelwa kunye ne-290 μg ngethuba lokutya-I-Institute of Medicine
- I-iodine yamanqaku ama-250 μg abesetyhini abakhulelweyo nabakhayo-I-World Health Organization
- I-Vitamin enezinga le-iodine ye-150 μg yabasetyhini abakhulelweyo nabaqeshisayo-I-American Thyroid Association
Izikhokelo zika-2011 zezifo ze-Thyroid ekukhulelweni nazo zincomela ukuxhaswa kwe-iodine ngexesha lokuqala kokukhulelwa, ukukhulelwa kunye nokuxeliswa.
Nangona abaninzi abafazi becinga ukuba iivithamini ezibelethwe nazo zonke izakhi ezisisiseko ezifunekayo ngumfazi okhulelweyo, umxholo we-iodine we-multivitamine engaphantsi kokuthengisa e-United States ayigunyaziwe. Oko kuthetha ukuba iivithamini zokubeletha zinamanqanaba ahlukeneyo enomxholo we-iodine, kwaye ngenxa yokuba iodow kuyo ivela kwimithombo eyahlukileyo, ihlala ihambisa iqondo eliqhelekileyo le-iodine ehluke kwiqondo elichaziweyo.
I- NEJM ibike malunga nokuvavanywa okwakubhekise kwi-127 engagunyazisiyo kunye nama-multivitamine angama-96 asematyaleni asematyaleni aseMelika. Kula ma-multivitamine, 114 (87 engabhalwanga phantsi, i-prescription 27) iqukethe iodine. Ngokubanzi, malunga nesiqingatha iivithamini ezivandlakanywe ziqukethe i-iodine, nge-32% ye-vitamine engaphantsi kwemithi engenazo iodine, kwaye i-72% yemigcino ye-vitamin engaphantsi kokufunda yayingekho iodine.
Phakathi kwalawo aquka i-iodine, i-89% iqulethe i-150 μg okanye ngaphezulu kwe-iodine kwi dose yemihla ngemihla. Uninzi lwazo lwalufumana iodode yazo kwi-kelp okanye iodidi ye-potassium. Abaphandi bavavanya umxholo we-iodine kwi-60 yamayeza amavithamini athathe i-iodine kwaye ifumene ukuba ngokuqhelekileyo, iivithamini nge-iodine ye-potassium, umxholo we-iodine wawungalingana no-76% we-content content ye-iodide ye-potassium.
I-kelp ayizange inike amazinga e-iodine athembekileyo, nangona kunjalo, kwaye ahlukeneyo ngama-50% ukusuka kumanqanaba achaziweyo. Iimpawu ezilishumi zinexabiso le-iodine ezithunyelwa ngaphantsi kwesigamu sezinga le-iodine.
Ngokutsho kweengcaphephe, ukuhlangabezana nezikhokelo ezingaphantsi kwe-150 μg zabasetyhini abakhulelweyo nabancengayo abanconywa yi-American Thyroid Association, abavelisi be-multivitamines ngaphambi kokubeletha e-United States kufuneka bakhuthazwe ukuba bahlanganise iodine-kodwa kuphela kwifom ye-iodide ethembekileyo ye-potassium - kwaye kubandakanye ubuncinane i-197 μg ye-iodide ye-potassium imihla ngemihla, eya kuqinisekisa ukuba ezi iivithamini ziqukethe i-150 μg ye-iodine yosuku olongezelelweyo.
Ngo-2015, i-US Council for Responsible Nutrition yabiza ukuba "bonke abakhiqizi bokuncedisa ukutya kunye nabathengisi baqale ukubandakanya ubuncinane i-150 μg ye-iodine kuzo zonke iintsuku ezongezelelweyo ze-multivitamin / amaminerali ezijoliswe kwabasetyhini abakhulelweyo nabancinci baseUnited States kwiinyanga ezili-12 ezizayo .
