Kafukufuku wa "shuga".
… Mu 1947, Center for Sugar Research inalamula pulogalamu yofufuza ya zaka khumi ya $57 kuchokera ku yunivesite ya Harvard kuti adziwe momwe shuga amapangira mabowo m'mano ndi momwe angapewere. Mu 1958, magazini ya Time inafalitsa zotsatira za kafukufuku yemwe poyamba adawonekera mu Dental Association Journal. Asayansi adatsimikiza kuti palibe njira yothetsera vutoli, ndipo ndalama zothandizira ntchitoyi zinaimitsidwa nthawi yomweyo.
"... Kafukufuku wofunikira kwambiri wokhudza momwe shuga amakhudzira thupi la munthu adachitika ku Sweden mu 1958. Iwo ankatchedwa "Vipekholm polojekiti". Opitilira 400 achikulire omwe ali ndi thanzi labwino amatsatira zakudya zoyendetsedwa bwino ndipo adawonedwa kwa zaka zisanu. Maphunzirowa adagawidwa m'magulu osiyanasiyana. Ena adatenga chakudya chosavuta komanso chosavuta panthawi yachakudya chachikulu, pomwe ena amadya zakudya zowonjezera zomwe zimakhala ndi sucrose, chokoleti, caramel kapena tofi pakati.
Mwa zina, phunziroli linapangitsa kuti: kugwiritsa ntchito sucrose kumathandizira kukula kwa caries. Chiwopsezo chimachulukira ngati sucrose ilowetsedwa munjira yomata, momwe imamatirira pamwamba pa mano.
Zinapezeka kuti zakudya zokhala ndi sucrose wochuluka mu mawonekedwe omata zimawononga kwambiri mano, pamene amadyedwa ngati zokhwasula-khwasula pakati pa chakudya chachikulu - ngakhale kukhudzana kwa sucrose ndi pamwamba pa mano kunali kochepa. Caries zomwe zimachitika chifukwa chodya kwambiri zakudya zomwe zili ndi sucrose zimatha kupewedwa pochotsa zakudya zovulaza zotere m'zakudya.
Komabe, zapezekanso kuti pali kusiyana kwapayekha, ndipo nthawi zina, kuwonongeka kwa mano kumapitilirabe ngakhale kuchotsedwa kwa shuga woyengedwa kapena kuletsa kwakukulu kwa kuchuluka kwa shuga wachilengedwe ndi chakudya.
