Sayansi Pomaliza Imati Kudya Pasitala Kutha Kukuthandizani Kuwonda
Zamkati
Zakudya za keto komanso moyo wina wotsika kwambiri wa carb ukhoza kukhala ukali wonse, koma kuwunikira kwatsopano kukukumbutsani kuti kudula carbs sizoyipa zofunikira kuti muchepetse thupi. Pepala la University of Toronto lofalitsidwa mu British Medical Journal tinawona momwe kudya pasitala ngati gawo la zakudya zochepa za GI (zomwe zimayang'ana kwambiri kudya zakudya zomwe zili zochepa pa glycemic index, muyeso wa momwe chakudya cham'magazi chimagawidwira mushuga), zimatha kukhudza kulemera kwa munthu komanso kuyeza kwa thupi. Kutembenuka, kudya motere kumatha kukuthandizani kuti muchepetse kunenepa.
Popeza pasitala ndi zakudya zina zama carb nthawi zambiri zimadziwika kuti ndi mdani wa sikelo, ofufuza adawona ngati kudya pasitala kumayambitsa kunenepa potengera zakudya zochepa za GI, zomwe nthawi zambiri zimawoneka kuti ndizothandiza kuchepetsa thupi. Adapeza kuti pakati pamayeso 32 omwe ophunzira adadya zakudya zochepa za GI zomwe zimaphatikizapo pasitala, sikuti amangopewa kunenepa, nthawi zambiri amachepa-pafupifupi pafupifupi mapaundi awiri.
Gululi linapanga kuwunikaku kuti athe kuthana ndi kuthekera kwa ma carbs kuvulaza kuyesa kuwonda, popeza pali nkhawa yokhudzana ndi chakudya, makamaka pasitala, watero wolemba nawo wolemba John Sievenpiper, MD, Ph.D."Sitinawone umboni wovulaza kapena kunenepa, koma ndizosangalatsa kuti tidawona kuchepa thupi," akutero Dr. Sievenpiper. Ngakhale pansi pazifukwa zomwe cholinga chake chinali kusunga kulemera, otenga nawo mbali adataya thupi popanda kuyesera, akuwonetsanso.

Koma musatenge izi ngati umboni wasayansi kuti mutha kudya mbale yayikulu ya pasitala pazakudya zilizonse ndikuchepetsa thupi. Ofufuzawo adatha kuwerengera kuchuluka kwa pasitala yomwe ophunzira adadya pafupifupi gawo limodzi mwa magawo atatu a maphunziro omwe adawunikira. Mwa gawo limodzi mwa magawo atatuwo, pasitala wodya pakati anali 3.3 servings (pa 1/2 chikho pa kutumikira) sabata. Kumasulira: Ambiri mwa anthuwa amadya pasitala pang'ono mlungu uliwonse kuposa momwe mungadyere limodzi ku lesitilanti. Sievenpiper anati: "Sindingafune kuti wina achotse pasitalayo kuti iwonjezere kulemera." "Mukadya pasitala wambiri, zimakhala ngati mutadya kwambiri chirichonse"Izi zikunenedwa kuti kudziletsa kumalamulirabe, ndipo kudya kwambiri pasitala (kapena china chilichonse) sikungapangitse kuti muchepetse thupi.
Komanso muyenera kudziwa, pali mwayi woti kuchepa thupi kunabwera chifukwa chodya zakudya zopanda GI, osati chifukwa chodya pasitala. Olemba kafukufukuyu anamaliza pamapepala awo kuti pakufunikanso kafukufuku wowunika ngati zotsatira zakuchepa kwa thupi zitha kugwira ngati pasitala inali gawo la njira ina yodyera ngati Mediterranean kapena zakudya zamasamba. (Chifukwa chachikulu chokankhira pasitala pakati pa maphikidwe okwanira 50 azakudya zaku Mediterranean.)
Nkhani yabwino kutenga pazonsezi: Zotsatira izi zikuwonetsa kuti kuchepa thupi komanso kudya pasitala sizogwirizana. Nyimbo kumakutu athu okonda carb. “Ndikuganiza kuti anthu akhoza kuonda pa zakudya zamtundu wa ‘zakudya zonse zoyenera’,” akutero Natalie Rizzo, M.S., R.D., mwini wa Nutrition à la Natalie. "Malingana ngati wina adya chakudya chopatsa thanzi ndi zipatso zambiri, nyama zam'mimba, mbewu zonse, ndi mapuloteni owonda, atha kuchepa thupi." Rizzo akuwonetsa kufikira kwa pasitala wothira nyemba kapena nyemba zonse, zomwe zimapatsa fiber ndi mapuloteni owonjezera pamitundu yamtunduwu. (BTW: Kodi Pasitala Wanga nyemba ndi Masamba Ali Abwino Kwa Inu?) Yesani kugwiritsa ntchito njira ya pasitala ndi ma veggies ambiri kapena msuzi wa marinara m'malo mwa msuzi wokometsera kirimu. Zimapindulitsanso kuwonetsetsa kuti pasitala (kapena chakudya chilichonse) chimakhala ndi gwero la mapuloteni ndi mafuta athanzi ndipo magawo amasungidwa, akuwonjezera. Ndiye chinsinsi chake ndi chiyani pa pasta ndi kuchepa thupi? Ngati mukuyesera kusiya mapaundi angapo, palibe chifukwa cholumbirira Zakudyazi kwathunthu. Ingowonjezerani zinthu zobiriwira ndikuwongolera gawo lina.
