Nangona iswekile kunye izinto eziswiti bakutya ukutya ngendlela efanayo, ubunzima babo abufani, ke amanyathelo asetyenziswayo awafani. Lo ngumgaqo wokuqala ekufuneka ufundwe ukuze ubeke iswekile endaweni yeswiti. Ngale ndlela, ukuba iresiphi kufuneka yenziwe iigram ezingama-200 ze ushukela, awunakho ukubeka inani elifanayo leswiti, ubeka umngcipheko wokuthambisa iresiphi kabini.
Kukho uluhlu olupheleleyo lwe izinto eziswiti ezingezizo kwintengiso, phakathi kwezinye i-aspartame, i-cyclamate kunye ne-saccharin, kodwa kuphela le yokugqibela ilungele ukusetyenziswa eontini kuba iyayichasa yomelele amaqondo obushushu. Kwelinye icala, ezi zinto zimnandi zithengiswa ngomgubo, ithebhulethi okanye ifom engamanzi.
Oku kuhlala kunjalo iswiti ezisetyenziselwa kakhulu iresiphi zokupheka, kunye neemveliso eziphekwe ehovini okanye kwimicrowave. Sibhekisa kwiiswidi ezimuncu. Ukulingana kulula kakhulu, iigram ezili-10 zeswekile zilingana negrama enye yeswiti, njengoko ubona, ushukela Isiqhelo sinobunzima obuphindwe kalishumi kuneswiti eyenziweyo. Ngale ndlela, ukubala inani lokugqibela, kufuneka kuphela ukwahlula iigrama zeswekile nge-10.
Iipilisi isalcharin iqulethe isixa esimnandi ngakumbi seswiti kunaleyo yonke. Ngale ndlela, indlela yokubala inani lamacwecwe yayifana neyangaphambili, yahlulwe nge-10, kodwa kulo mzekelo, iziphumo kufuneka ziphindaphindwe kabini.
El iswiti ulwelo inobunzima obulinganayo ngokulinganayo nencindi yomgubo oswiti, kodwa kwisiphumo seemilimitha endaweni yeegram, eli nani liyahluka kancinane. Kuya kufuneka uhlule inani elipheleleyo leegrama zeswekile ezichazwe kwiresiphi ngo-12,5. Iziphumo ezifunyenweyo ziyahambelana neemililitha zeswitile elulwelo.
