Vakadzi vane pamuviri - uye kunyanya, vakadzi vane pamuviri vane zvirwere zvehutano - vanoda iodine yakawanda . Iodine inofanirwa nokuti iri chivakwa chekuvaka muviri wehomoni yehomoni . Munguva yekutanga katatu yekuita pamuviri, apo fetus isingakwanisi kubereka hormone yekemikari, amai vanobudisa "utachiona hwehomoni yeviri," kureva kudaro. Kana iye asina iodine yakakwana muhutano hwake, hutano hwechecheche yake - uye hutano hwake - hunogona kutambura nekuda kwekushaya hutoni yakakwana yehomoni.
Kunyange zvazvo kushayikwa kweIodine kusati kwambova nyaya muUnited States, iri kuwedzera. Mukupera kwegore ra2006, Public Health Committee yeAmerican Thyroid Association (ATA) yakabudisa mushumo mupepanhau Utachiona hunodanidzira kuti vakadzi vose vane pamuviri vabatsire ne iodine. Uye 2003-2004 National Health and Nutrition Examination Surveys (NHANES) kuongorora kwakawana kuti vanopfuura 37% yevakadzi vane makore ekurera vana vane urinary iodine maonero anoratidza kushayikwa kweeodine zvishoma.
Yakurudzirwa Nhamba dzeIodine
Kunetseka pamusoro pekushaiwa kweiodini panguva yekuzvitakura uye lactation (kunyatsisa mwana) kwakaguma nemasangano akawanda anopa mirayiridzo uye mazano ekugadzira iodini. Maererano neThe New England Journal of Medicine (NEJM), aya ndiwo mazano ekurudzirwa kwemazuva ose panguva yekuzvitakura uye lactation:
- Iodini yezuva nezuva inowanikwa 220 μg panguva yekuzvitakura uye 290 μg panguva yeactation - The Institute of Medicine
- Iodini yezuva nezuva inotora 250 μg yevakadzi vane pamuviri uye vanokanganisa - World Health Organization
- Vitamini ine iodine yepamusoro ye 150 μg yevakadzi vane pamuviri uye vanokanganisa - The American Thyroid Association
Nhungamiro ya2011 yezvirwere zvehutachiona mukudzivirira zvakare inokurudzira iodine supplementation panguva yekusati yatanga pamuviri, pamuviri uye panguva yekuyamwisa.
Kunyange zvazvo vakadzi vakawanda vachifunga kuti mavitamini ane utachiona ane mishonga inokosha inodiwa nevakadzi vane pamuviri, zvinyorwa zveIodine zvematriitamine asati aberekwa kutengeswa muUnited States hazvisi mvumo. Izvozvo zvinoreva kuti mavitamini ekuberekwa ane maitiro akasiyana-siyana ehuodhi, uye nokuti iodine mavari inogona kubva kune zvakasiyana-siyana, inowanzotora huwandu chaihwo hweododhi inopesana nemashoko akadaro.
I NEJM yakataura pamusoro pekuongororwa kwakatarisa 127 isiri mishonga uye 96 mishonga yemishonga inoberekwa nevana vasati vambotengeswa muUnited States. Pakati idzi idzi, 114 (87 isina kunyorwa, gwaro rechipiri) rine iodine. Kakawanda, inenge hafu yemavithamini yakaongororwa ine iodine, ne 32% yevasina kuvhara mavitamini asina kubhadhara asina iodini chero ipi zvayo, uye kuvhara 72% yemishonga yemishonga inotanga kuberekwa isati yave isina iodine.
Pakati peiyo yaisanganisira iodine, 89% yaive ne 150 μg kana yakawanda yeododhi pamushandi wezuva nezuva. Vakawanda vakawana iodine yavo kubva kelp kana potassium iodide. Vatsvakurudzi vakaongorora huwandu hweiodine mumakumi matanhatu emavhidhiyo ekuberekwa ane iodine uye vakawana kuti kazhinji, mavitamini ane iodine ye potassium, zvinyorwa zveododhi zvaive zvakaenzana ne 76% yeo total potassium iodide content.
Iyo kelp haina kutora mazinga eododha akavimbika, zvisinei, uye akasiyana-siyana ne50% kubva kumazinga akataurwa. Mafuta gumi aiva neanodine tsika dzakapiwa zvishoma kudarika hafu yeodhi yepamusoro.
Maererano nenyanzvi, kusangana nemitemo mikuru ye 150 μg yevakadzi vane pamuviri nevanokwidziridzwa vakakurudzirwa neAmerican Thyroid Association, vanogadzira mamiriyoni ematinata muUnited States vanofanira kukurudzirwa kuisa iodine - asi mune imwe yakavimbika ye potassium iodide fomu fomu - uye kusanganisira zvinenge 197 μg ye iodide ye potassium zuva rega rega, izvo zvichaita kuti mavitamini aya ane 150 μg yeyodhesi yezuva rimwe nerimwe.
Muna 2015, US Council for Responsible Nutrition yakadana "vese vezvokudya-supplement manufacturers nevatengesi kuti vatange kusanganisira 150 μg yeododhi mumazuva ose e-multivitamin / mineral supplement zvinotarisirwa kuvakadzi vane pamuviri uye vanokanganisa muUnited States mumwedzi 12 inotevera .
