Iodine yakatanga kuwedzerwa kumunyu muna 1924 muUnited States, nekuda kwekuti zviitiko zvegoiter (chirwere chetachiona) chakawedzera kuitika muGreat Lakes uye Pacific Northwest region. Izvi zvaive nekuda kwekuderera kweiyo iodine muvhu uye kusavapo kwayo mukudya.
MaAmerican akagamuchira tsika yeSwitzerland yekuwedzera iodine pamunyu wetafura kugadzirisa dambudziko. Nenguva isipi, zvirwere zvethyroid zvakadzikira uye muitiro wacho wakava mupimo.
Munyu unoshandiswa semutakuri weiodine nekuti iri nyore nzira yekuunza iyo micronutrient mukudya kwako kwemazuva ese. Munyu unodyiwa nemunhu wese nguva dzose. Kunyange chikafu chemhuka chakatanga kuwedzera munyu une iodized.
Chii chinonzi munyu une iodine?
Izvi zvachinja kubva kuma20s nekuda kwekugadzirwa kwemakemikari ane chepfu uye dzimwe nzira dzinodhura dzekuunganidza munyu. Kare, munyu wakawanda waicherwa mugungwa kana kuti kubva munzvimbo dzakagara dziripo. Ikozvino munyu une iodized hausi musanganiswa wechisikigo, asi wakagadzirwa wakagadzirwa sodium chloride pamwe nekuwedzera iodide.
Iyo synthetic yekuwedzera iodide iripo mune zvinenge zvese zvakagadzikiswa chikafu - chikafu chakagadzirwa uye chikafu cheresitorendi. Inogona kuva sodium fluoride, potassium iodide - chepfu zvinhu. Tichifunga kuti tafura yemunyu yakasvibiswawo, haigoni kuonekwa sechinhu chine utano cheiodine.
Nekudaro, iodine inodiwa zvechokwadi kuti thyroid gland ibudise thyroxine uye triiodothyronine, maviri mahomoni akakosha emetabolism. Chero ipi zvayo yeiodine inobatsira pakugadzirwa kweT4 uye T3 thyroid hormone.
Ongororo yakaitwa paUniversity yeTexas kuArlington inoti munyu wakadaro haudziviriri kushomeka kweiodine. Masayendisiti akaongorora anopfuura 80 marudzi emunyu wekutengesa uye akawana kuti 47 yavo (inopfuura hafu!) haina kusangana neUS zviyero zvemazinga ayodhini. Uyezve, kana yakachengetwa mumamiriro emvura, iyo iodine yemukati muzvigadzirwa zvakadaro inoderera. Mhedziso: chete 20% yemhando yemunyu ine iodized inogona kunyatso kutorwa sosi yezuva nezuva iodine kudya.
