Kuwanda kwezvikafu zvekudya zvechikadzi kunokanganisa kukura kwevacheche nekuvapa kwete chete kukosha kwakakosha kwekudya, asiwo kunotsigira immune system nekugadzirisa basa remajeni mumatumbo evacheche, masayendisiti anoshuma mumagazini Nature.
Mumakore achangopfuura, kufarira mukuyamwisa kwakawedzera zvakanyanya. Muchinyorwa chazvino cheMasikirwo, Anna Petherick, mutori wenhau wekuSpain, akaongorora zvinyorwa zvesainzi zviripo uye akatsanangura mamiriro eruzivo nezve kuumbwa kwemukaka wezamu uye zvakanakira kuyamwisa.
Kwemakore akawanda, kukosha kwekudya kusina mubvunzo kwemukaka wevanhu uye basa rayo rinokosha mukudyisa vacheche uye kusimbisa masimba ezvirwere zvevana zvakazivikanwa. Zvidzidzo zvekutanga zvinoratidza kuti mukaka wezamu unopesvedzera kushanda kwemajini mumasero emudumbu muvacheche.
Masayendisiti akafananidza kutaura kweRNA mune formula-inodyiswa (MM) uye vacheche vanoyamwisa uye vakawana misiyano mukuita kwemajini akakosha anodzora kutaura kwevamwe vazhinji.
Sezvineiwo, zvakazoitikawo kuti kune misiyano pakati pezvokudya zvevanaamai vevana vanoyamwisa vanakomana nevanasikana - vakomana vanogamuchira mukaka kubva pamazamu avo zvakanyanya kupfuma mumafuta nemapuroteni kupfuura vasikana. Kune kunyange zvinwiwa zvisina zvachose kukosha kwekudya kune vacheche mumukaka wevanhu, kushanda chete kukura iyo chaiyo flora yehushamwari hwematumbo mabhakitiriya.
Nekuda kwehunyanzvi hutsva hwekutsvagisa kwemolecular biology uye tsvakiridzo yekushanduka-shanduka, tinodzidza kuti mukaka wevanhu, kunze kwekuve chikafu chevacheche, zvakare unofambisa masaini akakosha mukukura kwevana. (PAP)
