Eminyakeni yamuva nje kwanda ukwanda kokungezwani komzimba nokudla. Ngokuya ngemininingwane evela ku- ISpanish Society of Clinical Immunology and Allergy Yezingane (SEICAP), cishe izingane ezi-4-8% zaseSpain zihlushwa uhlobo oluthile lokungezwani komzimba nokudla okuthile, okuvame kakhulu ukuba ubisi, amantongomane (ikakhulukazi amakinati), inhlanzi, izimbaza, i-gluten kanye nesoya.
Lolu hlobo lokungezwani komzimba alunciphisi kuphela izinhlobo zokudla umuntu angazidla, kepha noma inani elincane nje lingadala izimpawu ezisukela ekuphendukeni kwesikhumba, izinkinga zokuphefumula, ukungakhululeki kokugaya ukudla kuze kube ukwethuka kwe-anaphylactic okungabulala. Ngenhlanhla ezimweni eziningi ukufa akwenzeki, kepha kuyenzeka kunciphisa ukudla futhi kudala ingcindezi ngokuhlala wazi njalo ukuthi yikuphi ukudla okudliwayo.
Ukuvikela ukubonakala kwalolu hlobo lokungezwani komzimba, izincomo ezijwayelekile kube ukubambezela ukwethulwa kokudla okungenzeka kube yi-allergenic. Kodwa-ke, emashumini eminyaka amuva nje, ezinye izifundo zishicilelwe ziphakamisa lokho ukwethula lokhu kudla kusenesikhathi kunganciphisa ubungozi bokungezwani komzimba nokudla.
Ocwaningweni olwenziwe kufayela le- Imperial College eLondon Idatha evela ezifundweni zangaphambilini eziyi-146 ezibandakanye ngokuphelele izingane ezingama-200.000 zahlaziywa. Imiphumela, ishicilelwe ephephabhukwini i-JAMA (Journal of the American Medical Association), kukhombise ukuthi izingane eziqale ukudla amaqanda aphakathi kwezinyanga ezine nezingu-4 ubudala zazinamathuba amancane angama-6% okuba nokungezwani nalokhu kudla uma kuqhathaniswa nezingane ezaqala ukukudla kamuva. Ngokuqondene namantongomane, kwatholakala ukuthi izingane eziqale ukuwugwinya phakathi kwezinyanga ezi-40 nezingu-4 ubudala zinamathuba amancane okuba ne-11% yokuhlushwa ukungezwani nawo.
Nokho, ababhali besifundo bayaxwayisa ukuthi la maphesenti ayizilinganiso zesikhathi esikhona futhi angashintsha njengoba kwenziwa ucwaningo olusha. Ngaphezu kwalokho, bancoma ukuthi bangakwethuli lokhu kudla ezinganeni esevele zinokunye ukudla noma okunye ukungezwani komzimba. Uma uthatha isinqumo sokunikeza amantongomane engane, akufanele neze aphelele ukugwema ukuminyana, kodwa kufanele anikezwe ngendlela yebhotela.
Ngakolunye uhlangothi, ukwethulwa kokuqala kokudla okungenzeka kube yi-allergenic kuphikisana nezincomo ze- I-World Health Organization (WHO) ukugcina ukuncelisa ibele kuphela kuze kube yizinyanga eziyisithupha ubudala, ngakho-ke, ababhali besifundo bakubheka lokho ucwaningo olwengeziwe luyadingeka ukuthola iminyaka eqondile yokwethulwa kwalokhu kudla.
Ngakho-ke sesivele silinde imiphumela emisha, lezi zincomo azithetheleli ukwethulwa kokudla ngaphambi kwezinyanga eziyisithupha, lapho ukuncelisa ibele kufanele kube kukodwa, kepha uma isingeniso sangaphambilini seqanda nontongomane, kanye nokunye ukudla.
