Ukudla utamatisi kuvikela abesifazane kumdlavuza webele ngesikhathi sokunqamuka kokuya esikhathini - isitatimende esinjalo senziwe ososayensi baseRutgers University (USA).
Iqembu lodokotela, eliholwa nguDkt. Adana Lanos, lithole ukuthi imifino nezithelo eziqukethe i-lycopene - ikakhulukazi utamatisi, kanye namagwava kanye nekhabe - kunganciphisa kakhulu ingozi yomdlavuza webele kwabesifazane be-postmenopausal, futhi ngaphezu kwalokho, babasize ukulawula. ukukhuluphala kanye namazinga kashukela egazini.
"Izinzuzo zokudla utamatisi omusha nezitsha ezilungiselelwe kubo, ngisho nangezincane, ngenxa yocwaningo lwethu, sezicacile," kusho u-Adana Lanos. Ngakho-ke, yidla izithelo nemifino eminingi enothe ngezakhi ezizuzisayo, amavithamini, amaminerali, namakhemikhali e-phytochemicals njenge-lycopene ukuze uthole izinzuzo zezempilo ezilinganiselwe. Ngokwemiphumela yocwaningo, singasho ukuthi ngisho nokudla nje imali enconyiwe yansuku zonke yezithelo nemifino kunikeza isivikelo kumdlavuza webele emaqenjini asengozini.
Ithimba lezesayensi likaDkt. Lanos lenze uchungechunge lwezivivinyo zokudla okunomsoco lapho abesifazane abangama-70 abangaphezu kweminyaka yobudala engama-45 babambe iqhaza. Bacelwa ukuthi badle inani lansuku zonke lokudla okuqukethe utamatisi amasonto ayi-10, okuhambisana nenkambiso yansuku zonke ye-lycopene ye-25 mg. Kwesinye isikhathi, abaphenduli kwakudingeka ukuthi badle imikhiqizo yesoya equkethe ama-40 g weprotheyini yesoya nsuku zonke, futhi, amasonto ayi-10. Ngaphambi kokuthatha izivivinyo, abesifazane bebekugwema ukudla okunconyiwe amaviki ama-2.
Kwavela ukuthi emzimbeni wabesifazane abadla utamatisi, izinga le-adiponectin - i-hormone ebhekene nokulahlekelwa isisindo kanye namazinga kashukela egazini - lenyuke ngo-9%. Ngesikhathi esifanayo, kwabesifazane ababengekho ngokweqile ngesikhathi socwaningo, izinga le-adiponectin landa kancane kancane.
“Leli qiniso lokugcina libonisa ukuthi kubaluleke kangakanani ukugwema isisindo esiningi,” kusho uDkt. Lanos. "Ukusetshenziswa kukatamatisi kunikeze impendulo ephawuleka kakhudlwana yama-hormone kwabesifazane abagcina isisindo esijwayelekile."
Ngesikhathi esifanayo, ukusetshenziswa kwe-soy akuzange kuboniswe kunemiphumela enenzuzo ekuqaguleni komdlavuza webele, ukukhuluphala, nesifo sikashukela. Ngaphambilini kwakucatshangwa ukuthi njengesinyathelo sokuvimbela umdlavuza webele, ukukhuluphala kanye noshukela ophezulu wegazi, abesifazane abangaphezu kweminyaka engama-45 kufanele bathathe inani elibalulekile lemikhiqizo equkethe i-soy.
Ukucabanga okunjalo kwenziwa ngesisekelo sedatha yezibalo etholwe emazweni ase-Asia: ososayensi baye baqaphela ukuthi abesifazane baseMpumalanga bathola umdlavuza webele izikhathi ezimbalwa kakhulu, ngokwesibonelo, abesifazane baseMelika. Kodwa-ke, uLanos uthe kungenzeka ukuthi izinzuzo zokusetshenziswa kwamaprotheni e-soy zikhawulelwe ezinhlotsheni ezithile (zase-Asia), futhi azidluleli kwabesifazane baseYurophu. Ngokuphambene nesoya, ukusetshenziswa kukatamatisi kubonakale kuphumelela kakhulu kwabesifazane baseNtshonalanga, yingakho i-Lanos incoma ukufaka okungenani inani elincane likatamatisi ekudleni kwakho kwansuku zonke, okusha noma kunoma yimuphi omunye umkhiqizo.
