Kubonakala ngathi kukho iindlela ezingaphezulu kunye nangaphezulu zokubilisa izithambiso zendalo kunye neemveliso kwiimarike. Abafundi bam abaninzi bayazi, ndihlala ndihlala i-Starbucks yokulungisa i-caffeine . Ngokuqhelekileyo, ndiyisela ikhofi yam emnyama, kodwa ngamanye amaxesha ndiya kwongeza ipakethi nehafu kunye nephepha elilodwa leswekile. Ngenye imini, ndaqaphela ukuba iipakethi zetshukela azifumaneki ndawo-kunoko ndibona iipakethi ezincinane ngemibala eyahlukileyo ukuquka ukukhanya okwesibhakabhaka, i-pink kunye nephuzi.
Ndihlolisise ngokuthe ngileyo ezi zithokozi ukubona ukuba kukho umahluko phakathi kwabo. Ekugqibeleni ndifumanisa ipaketi yam ishukela yam rhoqo ukuze ndifake ikhofi yam, ndaya eofisini. Kodwa ke ndizibuza ukuba ngaba kukho umntu oye wafumana impendulo ngenxa yokungabonakali kwamanye amazwe ngenxa yezi
Uphando olutshanje lweencwadi zonyango oluthole inqaku elipapashwe ngo-2015 ngabaphandi baseTexas, eMzantsi Carolina naseNebraska kwi-marketer entsha, ebizwa ngokuba yi-stevia. Ukuthengwa phantsi kwegama leTruvia igama, i-stevia ifumaneka kwisityalo se- Stevia rebaudiana , i-stevia ifakwe kwiimpawu zendalo zendalo, eziphantsi kweekhalori. Enyanisweni, iCoca-Cola kunye nePepsi ikhuphe iimveliso ngo-2014 ezibandakanya ishukela kunye ne-stevia (ingxube ye-fructose ye-corn syrup), kwi-colas. Ekubeni i-stevia ifumaneka kwiindawo ezininzi zokutya kunye neziphuzo, ukhuseleko lwalo mthakazelisi wendalo lubuzwa, ikakhulukazi amandla ayo okubangela ukuphazamiseka.
Yintoni uStevia?
U-Stevia rebaudiana isityalo apho i-stevia ifumaneka khona. Esi sityalo singabomndeni wase- Asteraceae kwaye sizalelwa eMzantsi Melika, apho sele isetyenziswe njengokutya kunye namayeza amakhulu eminyaka. I-Stevia ifumaneka kumagqabi esityalo kwaye ihlambuluke kakhulu ukuvelisa i-sweet-calor-calorie yonke i-sweetener engokwemvelo esebenzisa ukutya ezahlukeneyo namhlanje.
Ngaba i-Stevia yayingabangela ukuba iphendulwe?
Izityalo ezininzi kwiintsapho ze- Asteraceae ziyaziwa ukuba zenze iindidi ezahlukahlukeneyo zokuziphendulela , eziquka ukuphefumula kokuphefumula, ukudibanisa i-dermatitis kwiiprotheni zezityalo kunye nokutya kokutya kokutya ukutya kwemveliso. I-Asteraceae izityalo ezaziwa ngokubangela ukuba iziphumo zomsindo zibandakanya i- ragweed (i-pollen allergies), i-chrysanthemum (nxu lumene ne-dermatitis) kunye nembewu ye-sunflower (ukutya kokutya). Ekubeni i-stevia ihambelana nezityalo ezininzi eziyaziwa ngokubangela ukuba ziphendule, ezinye iingcali zincoma ukuba abantu abanezityalo ezinxulumene nezityalo kufuneka basebenzise i-stevia.
Noko ke, kukho ubungqina obuncinane bokuxhasa inkcazo yokuba i-stevia ibangela ukusabela komzimba kubantu abanezidumbu eziyaziwayo kwiintlobo ze-Asteraceae . Oku kunokwenzeka ngenxa yokuhlambuluka kakhulu kwemveliso ye-stevia, njengeTruvia. Kwabaninzi abantu, iifom ze-stevia ezihlambulukanga kakhulu zingenakuthi ziqulethe i-allergen kunye ne-antigen eziyimfuneko ukuze kubangele ukuphazamiseka. Ngakolunye uhlangothi, izitshalo ezingekho phantsi kweefestile zezityalo ze-stevia - ingakumbi ezo zifumaneka kwiivenkile zokutya ezempilo - zinethuba eliphezulu lokubangela ukuba abantu bangenelele kwizityalo ze-Asteraceae .
Kukho uphando olulodwa kuphela kwiincwadi zonyango obunobungqina obungqina bokuthi i-stevia ingabangela ukuphendula.
Ngo-2007, umphandi waseJapan wabika malunga neentsana ezimbini ezazifumana i-anaphylaxis ngenxa yokutya kwemveliso ye-stevia, enye yokutshiza kumaqabunga e-stevia kunye nomnye kwi-stevia engcolileyo exutywe ngamanzi. Zobabini iintsana zine- atopic dermatitis . Umphandi wabe esenza uvavanyo lwesikhumba kunye ne-stevia kwiintsana ezingama-200 waza wafumana izinga eliphezulu leemvavanyo zesikhumba ukuze aqhube kwi-dermatitis ne- asthma .
Ngaba Ndifanele Ndiphephe ukutya okuqukethe i-Stevia?
Akucaci ukuba abantu abaneembali zokungabikho kwemvelo kwizityalo ze-Asteraceae basengozini enkulu yokwenza iimpendulo ezithintekayo kwizidlo ezine-stevia ezihlambulukileyo.
Nangona kunjalo, izitshalo ezingekho phantsi kweso sityalo se-stevia, ezinjengezo ezifumaneka kwizibonelelo zokutya okanye kwiindawo zokutya ezempilo, kufuneka zikhunjulwe ngabantu abane-allergies kwi- Asteraceae izityalo.
