Vanamai vanopiwa ngwariro huru. Asi tsvakurudzo inoratidza kuti kudya kwababa vasati vabata pamuviri kunogona kuita basa rinokosha zvakaenzana pautano hwemwana. Tsvagiridzo nyowani inoratidza kekutanga kuti mazinga efolate yababa akakosha pakukura uye hutano hwemwana sezvaari kuna amai.
Muongorori McGill anoratidza kuti vanababa vanofanirwa kutarisisa zvakanyanya kumararamiro avo uye kudya kwavo vasati vabata pamuviri saamai. Pane kushushikana pamusoro pemhedzisiro yenguva refu yezvino kuMadokero kudya uye kusachengeteka kwekudya.
Tsvagiridzo yakanangana nevhitamini B9, inonziwo folic acid. Inowanikwa mumiriwo yemashizha yakasvibirira, zviyo, michero uye nyama. Zvinozivikanwa kuti kuitira kudzivirira kupfupfudzika nekuremara pakuzvara, madzimai anofanira kuwana folic acid yakakwana. Panenge pasina ngwariro yakabhadharwa kuti kudya kwababa kunogona kutapura sei utano nokukura kwomwana.
“Pasinei nechokwadi chokuti folic acid yava kuwedzerwa muzvokudya zvakasiyana-siyana, vanababa venguva yemberi vanodya zvokudya zvine mafuta akawanda, vanodya zvokudya zvinokurumidza kubikwa, kana kuti vakafuta havakwanisi kuyamwa uye kushandisa folic acid zvakanaka,” anodaro masayendisiti anobva kuKimmins Research Group. “Vanhu vanogara kuchamhembe kweCanada kana dzimwe nzvimbo dzenyika dzisina chikafu vanogona kunge vari panjodzi yekushaikwa kwefolic acid. Uye zvino zvakazozivikanwa kuti izvi zvinogona kuva nemigumisiro yakakomba kune embryo.
Vatsvakurudzi vakawana mhedziso iyi nekushanda nemakonzo uye kuenzanisa vana vevanababa vane kudya kwefolic acid kushomeka nevana vemadzibaba avo kudya kwavo kwaiva nehuwandu hwevhitamini. Vakaona kuti kushaikwa kwefolic acid kwababa kwakabatana nekuwedzera kwekuremara kwekuzvarwa kwemhando dzakasiyana muvana vake, zvichienzaniswa nembeva dzechirume dzakadyiswa huwandu hwakakwana hwefolic acid.
"Takashamiswa zvikuru kuwana kuwedzera kunenge 30 muzana yehurema hwekuberekwa mumararamiro evarume vane folate folate yakanga isina kukwana," akadaro Dr. Roman Lambrot, mumwe wemasayendisiti akabatanidzwa mukudzidza. "Takaona zvimwe zvakakomba skeletal anomalies zvaisanganisira zvese zviri zviviri craniofacial kuremara nekuremara kwemusana."
Ongororo yakaitwa neboka reKimmins inoratidza kuti kune zvikamu zvesperm epigenome zvine hanya nemararamiro uye kudya zvakanyanya. Uye ruzivo urwu runoratidzwa mune iyo inonzi epigenomic mepu, iyo inokanganisa kukura kwe embryo, uye inogonawo kukanganisa metabolism uye kukura kwezvirwere mumwana munguva refu.
Iyo epigenome inogona kufananidzwa nekuchinja kunoenderana nezviratidzo kubva kune zvakatipoteredza uye inobatanidzwawo mukukura kwezvirwere zvakawanda, kusanganisira kenza uye chirwere cheshuga. Zvaizivikanwa kare kuti maitiro ekudzima nekugadzirisa anoitika muepigenome apo urume hunokura. Ongororo itsva inoratidza kuti pamwe nemepu yebudiriro, urume hunotakurawo ndangariro yenzvimbo yababa, kudya uye mararamiro.
"Ongororo yedu inoratidza kuti vanababa vanofanirwa kufunga nezvezvavanoisa mumuromo, zvavanoputa uye zvavanonwa, uye kuyeuka kuti ivo vachengeti vechizvarwa," Kimmins anopedzisa. "Kana zvese zvikafamba sezvatinoshuvira, danho redu rinotevera richave rekushanda nevashandi vekiriniki yehunyanzvi hwekuzvara uye kudzidza kuti mararamiro, kudya kunovaka muviri uye varume vakafuta zvinokanganisa sei hutano hwevana vavo."
