Ucwaningo "loshukela".
… Ngo-1947, Isikhungo Sokucwaninga Ngoshukela sagunyaza uhlelo locwaningo lweminyaka eyishumi, $57 oluvela eNyuvesi yase-Harvard ukuthola ukuthi ushukela udala kanjani izimbobo emazinyweni nokuthi ungawugwema kanjani. Ngo-1958, umagazini i-Time washicilela imiphumela yocwaningo olwavela ekuqaleni kuyi-Dental Association Journal. Ososayensi banquma ukuthi yayingekho indlela yokuxazulula le nkinga, futhi uxhaso lwalo msebenzi lwamiswa ngokushesha.
“… Ucwaningo olubaluleke kakhulu lwemiphumela kashukela emzimbeni womuntu lwenziwa eSweden ngo-1958. Yayaziwa ngokuthi "iphrojekthi yeVipekholm". Bangaphezu kuka-400 abantu abadala abaphile kahle ngokwengqondo abalandela ukudla okulawulwayo futhi babonwa iminyaka emihlanu. Izifundo zazihlukaniswe izigaba ezahlukene. Abanye bathatha ama-carbohydrate ayinkimbinkimbi futhi alula kuphela ngesikhathi sokudla okuyinhloko, kanti abanye badla ukudla okwengeziwe okuqukethe i-sucrose, ushokoledi, i-caramel noma ithofi phakathi.
Phakathi kokunye, ucwaningo luholele esiphethweni esilandelayo: ukusetshenziswa kwe-sucrose kungaba nomthelela ekwakhiweni kwe-caries. Ingozi iyanda uma i-sucrose ingenwa ngendlela enamathelayo, lapho inamathela khona ebusweni bamazinyo.
Kwavela ukuthi ukudla okune-sucrose ephezulu efomini elinamathelayo kubangela umonakalo omkhulu emazinyweni, lapho zidliwa njengama-snacks phakathi kokudla okuyinhloko - ngisho noma ukuthintana kwe-sucrose ebusweni bamazinyo kwakufushane. I-Caries eyenzeka ngenxa yokusetshenziswa ngokweqile kokudla okune-sucrose ingavinjelwa ngokuqeda ukudla okunjalo okuyingozi ekudleni.
Nokho, kuphinde kwatholakala ukuthi kunomehluko womuntu ngamunye, futhi kwezinye izimo, ukubola kwamazinyo kuyaqhubeka naphezu kokuqedwa koshukela ocolisisiwe noma ukuvinjelwa okukhulu kwenani likashukela wemvelo nama-carbohydrate.
