I-World Health Organisation (WHO) ikhuphe isikhokelo esicebisa ukuba kungasetyenziswa izithambisi ezingeyoswekile (NSS) ukuze kulawulwe ubunzima.
I-NSS zizinto ezinokusetyenziswa endaweni yeswekile zasimahla eziphantsi okanye ezingenazo iikhalori kwaye zihlala zithengiswa, ngokutsho kwe-WHO, njengoncedo lokunciphisa umzimba okanye ukugcina ubunzima obusempilweni. Zikwacetyiswa njengendlela yokulawula iswekile egazini kubantu abanesifo seswekile.
Ingcebiso ye-WHO isekelwe kwiziphumo zophononongo olucwangcisiweyo lobungqina obubonisa ukuba ukusetyenziswa kwe-NSS akuboneleli ngenzuzo yexesha elide ekunciphiseni amafutha emzimbeni kubantu abadala okanye ebantwaneni.
Iziphumo zophando kwisikhokelo zibonise ukuba ukutya i-NSS eninzi kunxulunyaniswa nokunyuka kwama-23% komngcipheko wesifo seswekile sohlobo lwesibini xa sityiwa kwiziselo ezineswekile ze-NSS kunye nokunyuka kwama-34% komngcipheko xa songezwa ngabantu kwaye sityiwa ekutyeni naseziseloni.
Esi sikhokelo sikwacebisa ukuba kungasetyenziswa i-NSS njengendlela yokunciphisa umngcipheko wezifo ezingosuleliyo.
UFrancesco Branca, umlawuli we-WHO wezondlo kunye nokhuseleko lokutya, uthe: “Ukutshintsha iiswekile ezingenaswekile nge-NSS akuncedi ekulawuleni ubunzima kwixesha elide. Abantu kufuneka bacinge ngezinye iindlela zokunciphisa ukutya iiswekile ezingenaswekile, njengokutya ukutya ngeeswekile zendalo, njengeziqhamo, okanye ukutya neziselo ezingenaswekile.”
I-NSS eqhelekileyo iquka i-saccharin, i-sucralose, i-stevia, i-acesulfame K, i-aspartame, i-advantame, i-cyclamates, i-neotame kunye ne-stevia derivatives.
Wongeze wathi: “I-NSS ayizizo izinto ezibalulekileyo zokutya kwaye ayinazo izondlo. Abantu kufuneka banciphise ubumnandi bokutya ngokupheleleyo, baqale kwasebuntwaneni, ukuze baphucule impilo yabo”.
Esi sikhokelo sisebenza kuzo zonke izithambisi ezingezona izondlo ezenziweyo nezivela ngokwendalo okanye eziguqulweyo ezingachazwanga njengeeswekile ezifumaneka ekutyeni nakwiziselo ezenziweyo, okanye ezithengiswa njengemveliso ezongezwa ekutyeni nakwiziselo ngabathengi. Nangona kunjalo, esi sikhokelo asisebenzi kubantu abanesifo seswekile esele sikhona.
UKeith Ayoob, umcebisi wesayensi kwiBhunga loLawulo lweeCalorie, uthe esi sikhokelo asizange siqwalasele abantu abaphila nesifo seswekile apho i-NSS inokuba "nendima ebalulekileyo ekuthobeleni iimfuno zokutya ezifunekayo".
Wongeze wathi: “Ukugxininisa kwe-WHO ekugxileni kuphela ekuthinteleni ukutyeba okungempilo kunye nezifo ezingosuleliyo, ubuncinane, kuyinto ephosakeleyo. Isigqibo se-WHO sokungagxininisi kwixabiso leeswiti ezingenaswekile kubantu abanesifo seswekile sifikelela kwinqanaba lokuba azinakwamkeleka. Ukwenza kwabo njalo kuyayilahla ixabiso kunye luncedo lwe-NSS kubantu abaphila nesifo seswekile kunye nangaphambi kokuba babe nesifo seswekile, nto leyo ebangela ukuba badlule kakhulu kwi-10% yabemi behlabathi.”
Le ngcebiso ayisebenzi kwiiswekile ezineekhalori eziphantsi kunye nee-alcohols zeswekile (ii-polyols), eziziswekile okanye izinto eziphuma kwiswekile ezineekhalori kwaye azithathwa njenge-NSS.
