Masayendisiti akawana kuti vakadzi vane pamuviri vanodya michero yakawanda, miriwo uye zviyo, uye kunwa mvura yakakwana, kashoma kuti varasikirwe nemwana semugumisiro wekuzvarwa nguva isati yakwana.
Imwe ongororo yeSwedish-Norwegian-Icelandic yakawana kudya kwezviyo zvemichero-yemiriwo (vesainzi vakazvidaidza kuti "zvinonzwisisika") sekuwedzera kuchengetedzeka kwe fetus. Izvo zvakaonekwawo kuti imwe kudya (kunonzi "tsika") ine mbatatisi yakabikwa nemiriwo uye mukaka wakaderera-mafuta (rudzi rwe "chikafu chekudya") inovimbisawo kuchengetedzwa kwe fetus uye hutano hwaamai. Panguva imwecheteyo, yakave yakasimbiswa kuti kudya kwe "Western" kune munyu, shuga, chingwa, zvihwitsi, nyama yakagadzirwa uye zvakafanana zvokudya zvisina kunaka zvine ngozi kune fetus uye mune dzimwe nguva zvinotungamirira pakurasikirwa kwayo.
Chidzidzo chacho chakaitwa pahwaro hwemashoko akawanikwa kubva ku66 zviuru zvevakadzi vane utano hwakanaka, vaiva ne3505 (5.3%) kuberekwa nguva isati yakwana (miscarriages), izvo zvakaguma nekufa kwemwana. Panguva imwecheteyo, vanachiremba vakataura kuti kuparara kwepamuviri ndiko kunokonzera kufa kwe fetus mu 75% yezviitiko (kureva, zviri pachena dambudziko guru rekuberekwa). Nheyo yekuongorora maitiro ekudya kwevanaamai aive akadzama diaries ezvekudya ayo vakadzi vakachengeta mumwedzi yekutanga ye4-5 yekuzvitakura.
Rondedzero yakazara yezvokudya zvakakodzera vanaamai vane pamuviri, uye izvo zvakanakisisa kunamatira kubva mumwedzi yekutanga, zvinosanganisira: miriwo, michero, mafuta emiriwo, mvura sechinwiwa chikuru, zviyo zvezviyo uye chingwa, zvakapfuma fiber. Masayendisiti akaona kuti zvinonyanya kukosha kutevera kudya kwakakodzera kwevakadzi vanenge vava kuda kusununguka mwana wavo wekutanga. Iri muboka iri remadzimai anotarisira kuti kudya kwevegan, uye zvishoma, "chikafu" chikafu chine mbatatisi yakabikwa, hove nemiriwo, zvinokonzera kuderera kwakanyanya kwengozi yekuparara, pamwe nekuzvarwa kamwe kamwe.
Vanyori vekudzidza vanosimbisawo mumushumo wavo kuti mukudya kwevakadzi vane pamuviri, zvokudya zvinodyiwa nemukadzi zvakakosha kudarika izvo zvaakasiya zvachose. Ndiko kuti, iwe haufanirwe kunetseka zvakanyanya kana iwe usingakwanise kuzvidzora uye kudya zvimwe zvinhu zvakashata kubva mukudya - asi chikafu chine hutano chinofanira kudyiwa nguva dzose, zuva nezuva, pasina kunyima muviri huturu hunoda.
Ichi chidzidzo chakaratidza kubudirira kwekudya "nzira yekare" - ndiko kuti, chokwadi che "Kudya nhamba 2", iyo vanachiremba zvino vanowanzokurudzira kuvakadzi vane pamuviri. Asi zvakare yakasimbisa kukosha kwakanyanya kwekudya "kutsva" kuine huwandu hwakawanda hwemichero mitsva, miriwo, uye zviyo zvakakwana (kureva, kudya kwevegan, sekutaura).
Purofesa Lucilla Poston weKing’s College London akataura pamusoro pezvakabuda muNordic Science Alliance, achiti izvi hazvisi kure neongororo yekutanga inoratidza kukosha kwekudyiwa kwemichero nemiriwo naamai vane pamuviri, uye vakakurudzira vanachiremba pasi rose kuti “vaunze shoko iri vakadzi vane pamuviri pasi rose kuitira kuti vadye zvokudya zvine utano.”
