Olemera mu isoflavones, soya akhoza kukhala othandiza kwa amayi omwe ali ndi vuto lotaya mapaundi owonjezera panthawi yosiya kusamba, akuwonetsa asayansi omwe kafukufuku wawo adasindikizidwa mu Journal of Obstetrics & Gynecology.
Kuchepa kwa kupanga estrogen yotsagana ndi kutha kwa msambo kungayambitse matenda ambiri, monga kutopa kapena kutentha thupi, ndipo pang'onopang'ono kagayidwe kake kamathandizira kuti minofu ya adipose iwundike. Kwa nthawi ndithu, asayansi akhala akukayikira kuti soya angathandize kuchepetsa zizindikiro za kusintha kwa msambo chifukwa cha katundu wake, koma kafukufuku mpaka pano sanalole kuti apeze mfundo zolimba.
Kafukufuku waposachedwapa wa ofufuza a ku yunivesite ya Alabama, Birmingham, anakhudza akazi 33, kuphatikizapo 16 African American akazi, amene kumwa tsiku smoothie kwa miyezi itatu munali 160 milligrams soya isoflavones ndi 20 magalamu a soya mapuloteni. Azimayi omwe ali m'gulu lolamulira ankamwa mkaka wa mkaka wokhala ndi casein.
Pambuyo pa miyezi itatu, computed tomography inasonyeza kuti amayi omwe amamwa soya smoothies anali ndi kuchepa kwa mafuta ndi 7,5%, pamene amayi omwe amatenga placebo adawonjezeka ndi 9%. Nthawi yomweyo, adawona kuti azimayi aku America aku America adataya pafupifupi 1,8 kg yamafuta onse amthupi, pomwe azimayi oyera adataya mafuta am'mimba.
Olemba a phunziroli akufotokoza kusiyana kwake, komabe, chifukwa chakuti akazi oyera, mafuta ambiri amasungidwa m'chiuno, kotero zotsatira za chithandizo zikuwonekera kwambiri apa.
Komabe, Dr. Oksana Matvienko (University of Northern Iowa) amakayikira mfundozi, ponena kuti kafukufukuyu anali waufupi kwambiri ndipo amayi ochepa kwambiri adatenga nawo mbali. Pakufufuza kwake, Matvienko adatsata amayi 229 pa chaka omwe adamwa mapiritsi okhala ndi ma milligrams 80 kapena 120 a soya isoflavones. Komabe, sanazindikire kusintha kulikonse kokhudzana ndi kutaya mafuta poyerekeza ndi gulu la placebo.
Matvienko amanena, komabe, kuti computed tomography ndi yovuta kwambiri kuposa x-ray yomwe imagwiritsidwa ntchito pofufuza, kotero ofufuza a yunivesite ya Alabama ayenera kuti adawona kusintha komwe sikunawoneke ndi gulu lake. Kuonjezera apo, kusiyana kwa zotsatira kungafotokozedwe ndi mfundo yakuti m'maphunziro apitalo, amayi amangopatsidwa ma isoflavones, ndipo m'maphunziro apano amakhalanso ndi mapuloteni a soya.
Onse omwe adalemba kafukufuku waposachedwa komanso wam'mbuyomu adatsimikiza kuti sizikudziwika ngati zotsatira za soya zitha kusintha kwambiri thanzi la amayi panthawi komanso pambuyo posiya kusamba (PAP).
