Bambalwa abantu abazi ukuthi i-folic acid iyinvithamini B9 enomswakama. Kubalulekile ekukhuleni nasekuthuthukisweni kwezinhlelo zokuzivikela komzimba nokuzivikela. Ukubaluleka kwe-folic acid yokukhulelwa kunzima ukugcizelela. Kuyadingeka, okokuqala, ukwakheka kahle kwe-embryo, ngoba iqhaza ekuqaliseni i-DNA. I-folic acid iyasiza futhi ngenqubo esebenzayo yokuhlukaniswa kwamaseli nokukhula. Iyakwazi ukuvimbela ingane ukuthi ikwazi ukuthuthukisa amaphutha ahlukahlukene, kufaka phakathi ukukhubazeka ebuchosheni kanye ne-neural tube. Ngaphezu kwalokho, i-folic acid ihilelekile ekwakheni igazi (ukwakheka kwama-erythrocytes, amaplatelet nama-leukocytes), kubaluleke kakhulu ekukhuleni nasekuthuthukiseni i-placenta nezitsha ezintsha esibelethweni. I-folic acid iyadingeka ngesikhathi sokubeka ubuchopho nesistimu yesifo se-fetus.
Ukwamukelwa kwe-folic acid kufanele kuqale izinyanga ezimbalwa ngaphambi kokukhulelwa okuhleliwe futhi kuqhubekele konke ukuqala kokukhulelwa, ngoba phakathi nalesi sikhathi izingxenye ezibalulekile njengezobuchopho kanye nesimiso sezinzwa zomntwana zakhiwa.
Kwenzekani nge-lack of folic acid?
Izimpawu zokuntuleka kwe-folic acid ezinkathini zokuqala ziwukukhathala, ukuphelelwa yifiso, ukucasula. Njengoba kunesifo esibi kakhulu se-acid, owesifazane angakwazi ukuthuthukisa i-megaloblastic anemia lapho umnkantsha wamathambo uqala ukukhiqiza amangqamuzana aphuzi egazi. Lesi simo sihambisane nokuhuda nesisu, ubuhlungu besisu, ukulahlekelwa izinwele, izinkinga zememori nokubukeka kwezilonda ezibuhlungu emqaleni nasemlonyeni.
Njengoba kunesifo esingapheliyo se-folic acid, umuntu uqala ukuqhuma njalo. Amantombazane angase abone ukubambezeleka ekufikeni kwentsha. Kwabesifazane asebekhulile, kwenzeka ukuphuma esikhathini sokuqala, futhi kulabo asebekhulile, ukuntuleka kwevithamini B9 kuyingozi ekuthuthukiseni ukuqina kwesifo sofuba kanye nokwanda kwegazi lokuhlaselwa kwenhliziyo nokushaya.
Kungani folic acid ekhulelwe?
Ukuntuleka kwe-folic acid ngesikhathi sokukhulelwa kuyingozi kakhulu. Iholela ezintweni ekuthuthukiseni i-neural tube yomntwana - ukungabikho kobuchopho, ukwakhiwa kwe-cerebral hernias, i-hydrocephalus, i-spina bifida. Kungase kube nokukhubazeka kusuka kwamanye amasistimu omzimba: izinkinga ze-cardiovascular system, ukwakheka kwe-hare lip kanye ne-cleft palate.
Ingozi eyengeziwe yokukhulelwa kwesisu, iphazamise ukuthuthukiswa kwezicubu ezibandayo, kunengozi yokuthunjwa kwe-placenta, ukuzala noma ukulibazisa ukukhula komntwana.
Isilinganiso se-folic acid ekukhutheni
Ngokuqondene nomthamo we-folic acid, kufanele umiswe udokotela oya khona. Ukudla okuphakathi kwe-folic acid kwabesifazane abakhulelwe kungama 600 mkg. Uma abesifazane bebonisa izimpawu ze-folic acid ezingenayo noma bebe nezinkinga zokubeletha izingane ezinokukhubazeka ezihambisana nokungaqiniseki kahle, umthamo we folic acid ukwandisa ku-5 mg ngosuku. Leli dozi likhonjiswa ngesikhathi sokulungiselela ukukhulelwa, kanye nasesigabeni sokuqala sokukhulelwa.
Awukwazi ukuhlola ngokuzimela izinga lezinselele futhi ubeke umuthi ngaphandle kokubonisana nodokotela wakho. Akulungile futhi akulawulwa
I-folic acid eyengeziwe ngesikhathi sokukhulelwa kungaholela ekuzalweni kwezingane ezigulayo ezisengozini yokuthuthukisa i-asthma ngaphambi kweminyaka engu-3. Ezinganeni ezizalwa ngabesifazane abangaphezu kuka-B9, ingozi yokuthuthukisa izifo zokuphefumula iphezulu kuze kube izinyanga eziyisishiyagalombili.
Ngenhlanhla, i-folate excess isingavamile kakhulu. Ezimweni eziningi, inani elidlulele likhishwa kalula emzimbeni.
