Ngokwesiko, kwakukholelwa ukuthi kwakuyimpilo kamama ngaphambi kokukhulelwa enquma inkambo yokukhulelwa kanye nempilo yengane engakazalwa. Kodwa imiphumela yocwaningo lwakamuva iyakuphikisa lokho kwaziswa. Kuvela ukuthi impilo kababa wesikhathi esizayo ayibalulekile kangako kunempilo kamama. Futhi kubaluleke kakhulu ukuthi ingakanani imifino nemifino ayidlayo ekudleni. Eqinisweni, ososayensi baye baqinisekisa ukuthi obaba abangama-vegan banezingane ezinempilo.
Lolu cwaningo, olwenziwa eNyuvesi yaseMcGill yaseCanada, luhlole kabanzi umphumela kavithamini B-9 (i-folic acid) ongancibiliki emanzini osetshenziswa uyise wengane ezintweni ezinjengokukhula kombungu kanye nokwenzeka kokuzalwa kokukhubazeka, kanjalo ingozi yokuphuphuma kwesisu.
Ngaphambilini kwakukholelwa ukuthi lezi zinkinga zathinteka ngokuqondile, okokuqala, ngenani lemifino eluhlaza, okusanhlamvu nezithelo ezidliwa ngumama - ngaphambi nangesikhathi sokukhulelwa. Kodwa-ke, idatha etholiwe ikwenza kucace ukuthi inani lokudla kwezitshalo ngisho nokuphila kukababa okunempilo noma cha kakhulu nakho kunquma inkambo yokukhulelwa kukamama kanye nempilo yengane!
USarah Kimmins, umholi weqembu lezokwelapha elenza lokhu kuhlola, wathi: “Naphezu kweqiniso lokuthi i-folic acid manje isinezelwa ekudleni okuningi, uma ubaba edla ngokuyinhloko ukudla okunama-kilojoule amaningi, ukudla okusheshayo, noma ekhuluphele, cishe wayezodla. akakwazanga ukumunca levithamini ngokwanele (ukukhulelwa ingane enempilo - iVegetarian).
Uzwakalise ukukhathazeka kwakhe ngokuthi “Abantu abahlala enyakatho yeCanada nakwezinye izifunda lapho ukudla okungenamsoco kungenamsoco basengozini yokuntuleka kwe-folic acid. Futhi siyazi ukuthi lolu lwazi luzodluliselwa ngofuzo lusuka kubaba luye endodaneni, futhi imiphumela yalokhu izoba mibi kakhulu.”
Ukuhlolwa kwenziwa ososayensi baseCanada emaqenjini amabili amagundane (amasosha omzimba acishe afane nomuntu). Ngesikhathi esifanayo, iqembu elilodwa lalihlinzekwa ngokudla okuqukethe inani elanele lemifino eluhlaza nokusanhlamvu, kanti elinye ngokudla okungenamsoco ku-folic acid. Izibalo zokukhubazeka kwengane zibonise ingozi enkulu kakhulu empilweni nasempilweni yenzalo kubantu abathola i-vitamin B6 encane.
UDkt. Lamain Lambrot, omunye wososayensi ababesebenza kulo msebenzi, wathi: “Samangala lapho sithola ukuthi umehluko enanini lengane ekhubazekile yayingamaphesenti angaba ngu-30. Obaba ababengenayo i-folic acid bazala izingane ezinempilo ebuthakathaka ngokuphawulekayo.” Uphinde wabika ukuthi uhlobo lokukhubazeka kwengane eqenjini elintula i-B6 lwalunzima kakhulu: “Sibone ukungahambi kahle okunzima kwesakhiwo sohlaka lwamathambo namathambo, okuhlanganisa ubuso nomgogodla.”
Ososayensi bakwazi ukuphendula umbuzo wokuthi idatha yokudla kukababa ithinta kanjani ukwakheka kwe-fetus kanye nokuvikeleka kwengane engakazalwa. Kuvele ukuthi ezinye izingxenye ze-sperm epigenome ziyazwela olwazini olumayelana nendlela ubaba aphila ngayo, ikakhulukazi uma kuziwa ekudleni. Le datha ifakwa kulokho okubizwa ngokuthi "imephu ye-epigenomic", enquma impilo ye-fetus esikhathini eside. I-epigenome, nayo ethonywa isimo semvelo yalapho ubaba ehlala khona, inquma ukuthambekela kwezifo eziningi, kuhlanganise nomdlavuza nesifo sikashukela.
Ososayensi bathola ukuthi nakuba (njengoba bekwaziwa ngaphambili) isimo esinempilo se-epigenome singabuyiselwa ngokuhamba kwesikhathi, nokho, kunomphumela wesikhathi eside wendlela yokuphila nokudla kukababa ekubunjweni, ekukhuleni kanye nempilo yonke ye-epigenome. umbungu.
USarah Kimmins wafingqa lokhu kuhlola: “Okuhlangenwe nakho kwethu kuye kwabonisa ukuthi obaba bakusasa kufanele bakuqaphele lokho abakudlayo, ababhemayo, nabakuphuzayo. Unesibopho sofuzo lwalo lonke uhlobo ezizukulwaneni eziningi ezizayo.”
Isinyathelo esilandelayo ithimba eliqede lolu cwaningo elifuna ukusithatha wukusebenzelana eduze nomtholampilo wokuzala. UDkt. Kimmins uphakamise ukuthi, ngenhlanhla, kungaba nokwenzeka ukuthola inzuzo eyengeziwe engokoqobo olwazini olutholiwe lokuthi ukukhuluphala ngokweqile nokungadli ngokwanele kukababa kwemifino nokunye ukudla okuqukethe i-B6 kulimaza umbungu futhi kungase kube yingozi empilweni nasempilweni. yekusasa. ingane.
