Imbi kangakanani i-Red 40 kunye nedayi yokwenziwa ngaphezulu?
Abantu baseMerika ngoku batya idayi yokutya ngokuphindwe kahlanu kunaleyo sayenzayo ngowe-1955. Loo manani ayothusi kangako xa ucinga ukuba ukususela ngoko idayi yokutya iye yenza ukutya kwethu okumibalabala-ukususela kwisidlo sakusasa ukuya kwi-ice cream. Ngelixa imibala yendalo eyenziwe ngokutya okufana ne-beet iyafumaneka, abaninzi abavelisi bakhetha idayi zokwenziwa-ezinokuba neziphumo eziyingozi kwimpilo, ngakumbi kubantwana, ngokwengxelo yamva nje evela kwiziko leSayensi kwiNdla yoLuntu. Yiyo loo nto i-Washington, D.C.-based user-watchdog group icele uLawulo lokuTya kunye neDrugs ukuba libavale. Ezo dayi zokutya ezenziwe ngumntu zivela kuluhlu lwezithako njengegama lombala onenombolo elandelayo: Blue 1 and 2, Citrus Red 2, Green 3, Red 3 and 40, Yellow 5 and 6.
utywala obugudileyo ukusela ngqo
Awona matyala amathathu asetyenziswa kakhulu-i-Yellow 5, i-Yellow 6 kunye ne-Red 40-ziqulathe iikhompawundi, kuquka i-benzidine kunye ne-4-aminobiphenyl, ukuba uphando ludibanise nomhlaza.
Uphando lukwanxulumanise iidayi zokutya neengxaki ebantwaneni eziquka izinto ezingahambisani nezinto ezithile emzimbeni, ukuxakeka kakhulu, ukuphazamiseka kokufunda, ukucaphuka nokuba ndlongondlongo. Uphononongo lwase-U.S. olupapashwe kwiSayensi lufumanise ukuba xa abantwana abafumene amanqaku aphezulu kwisikali sokulinganisa ukungasebenzi ngokugqithisileyo besitya umdibaniso wedayi yokutya benza okubi kakhulu kuvavanyo olulinganisa ukukwazi kwabo ukukhumbula imifanekiso kunaxa besela i-placebo. Uphononongo lwango-2007 lwaseBritane lwafumanisa ukuba abantwana abatya umxube wedayi zokwenziwa eziqhelekileyo babonisa ukuziphatha okugqithisileyo kwiyure nje yokusetyenziswa. (Aba bantwana babengafunyaniswanga ukuba bane-ADD okanye i-ADHD.) Iziphumo, ezapapashwa kwi The Lancet, zabangela ukuba i-Arhente yeMigangatho yoKutya yaseBritani ikhuthaze abavelisi ukuba bafumane ezinye iindlela ezizezinye kunedayi zokutya. NgoJulayi ka-2010, isigunyaziso sePalamente yaseYurophu sokuba ukutya neziselo ezinedayi zokutya kufuneka zibhalwe ngolo hlobo zaqalisa ukusebenza kuyo yonke iManyano yaseYurophu.
Ubungqina bokuqala bubonisa ukuba abantwana abaninzi banovakalelo oluncinci kwiidayi zokutya-kwaye ipesenti encinci inovakalelo kakhulu. 'Sibona ukusabela kubantu abanovelwano olubandakanya iimpawu ezingundoqo ze-ADHD, njengobunzima bokuhlala esitulweni kunye nokuphazamisa iincoko,' utsho uDavid Schab, MD, MPH, unjingalwazi oncedisayo wezengqondo kwiYunivesithi yaseColumbia kunye nombhali-mbhali we-meta-analysis ka-2004. efumene idayi yokutya ikhuthaza ukuziphatha kakubi kubantwana abasele bexakekile. Nangona kunjalo, utsho uSchab, esi ayisosona sizathu sinyanzelisa ukuba uyeke idayi zokutya. 'Ukutya okunedayi kuhlala kugcwele ezinye iingxaki zesondlo, njengeekhalori ezigqithisileyo namafutha,' utsho uSchab, obonisa ukuba ukutyeba ngokugqithiseleyo kwabantwana yeyona nto ixhalabisa kakhulu impilo yoluntu.
Okukwintsusa: Ukuba unexhala, yeka iidayi zokwenziwa ezinokuba yingozi. Khangela ukutya okune-USDA eluhlaza-kunye-mhlophe ye-USDA eqinisekisiweyo yeleyibhile yezinto eziphilayo, kodwa qaphela ukuba ukutya okubhalwe 'okwenziwe ngezinto eziphilayo' kusenokuthi kuqulethe idayi zokwenziwa. Unokujonga kwakhona uluhlu lwezithako zemveliso ye-beet, i-carotenes, i-annatto, i-capsanthin (isicatshulwa se-paprika) -njengoko zonke ziyimibala yendalo. Ngokuchaseneyo, amagama athi 'umbala ongeyonyani,' 'umbala wokufakelwa' okanye 'umbala wongeziweyo' ikwabonisa ukuba ii-pigments ezivela kwindalo zasetyenziswa njengoko iidayi zokwenziwa kufuneka zidweliswe ngamagama azo.
