UStevia uvame ukubhekwa njengothatha isikhundla sikashukela esiphephile nesinempilo esinganambitha ukudla ngaphandle kwemiphumela emibi yezempilo exhumene noshukela ocwengekile.

Iphinde ihlotshaniswe nezinzuzo eziningana zezempilo, njengokuncipha kokudla ikhalori, amazinga kashukela egazini, kanye nobungozi bezimbotshana (,,).

Kodwa-ke, okunye ukukhathazeka kukhona ezungeze ukuphepha kwe-stevia - ikakhulukazi kubantu abathile abangazwela kakhulu emiphumeleni yayo.

Lo mbhalo uhlola ukuphepha kwe-stevia ukusiza ukuthola ukuthi kufanele uyisebenzise.

Kuyini uStevia?

UStevia uswidi wemvelo otholakala emaqabungeni esitshalo se-stevia (UStevia rebaudiana).

Njengoba inama-calories ayi-zero kodwa imnandi ngokuphindwe ka-200 kunoshukela wasetafuleni, kuyinketho ethandwayo kubantu abaningi abafuna ukwehlisa isisindo nokwehlisa ukudla ushukela ().

Le sweetener iphinde ihlotshaniswe nezinzuzo eziningana zezempilo, kufaka phakathi ushukela wegazi ophansi namazinga we-cholesterol (,).

Noma kunjalo, imikhiqizo ye-stevia yezohwebo iyahlukahluka ngekhwalithi.

Eqinisweni, izinhlobo eziningi emakethe zicwengeke kakhulu futhi zihlanganiswe namanye amaswidi - njenge-erythritol, dextrose, ne-maltodextrin - engashintsha imiphumela yayo engaba khona yezempilo.

Okwamanje, amafomu angacutshungulwa kancane kungenzeka ahlehle ocwaningweni lwezokuphepha.

Izinhlobo ze-stevia

I-Stevia itholakala ngezinhlobonhlobo eziningana, ngalunye luhlukile ngendlela yokucubungula nezithako zalo.

Isibonelo, imikhiqizo eminingi edumile - njengeStevia eRaw naseTruvia - iyizinhlanganisela ze-stevia, okungenye yezinhlobo ze-stevia ezicutshungulwa kakhulu.

Zenziwe ngokusebenzisa i-rebaudioside A (Reb A) - uhlobo lokukhishwa kwe-stevia elicwengiweyo, eceleni kwamanye amaswidi afana ne-maltodextrin ne-erythritol ().

Ngesikhathi sokucubungula, amaqabunga afakwa emanzini bese edluliswa kusihlungi notshwala ukuze ahlukanise uReb A. Kamuva, okukhishwayo kuyomiswa, kufakwe ikristalu, bese kuhlanganiswa namanye ama-sweeteners kanye nama-filler ().

Ukukhishwa okumsulwa okwenziwe kuphela kuReb A nakho kuyatholakala njengoketshezi kanye nempushana.

Uma kuqhathaniswa nezingxube ze-stevia, ukukhishwa okumsulwa kubhekana nezindlela eziningi zokucubungula - kepha akuhlanganisiwe namanye ama-sweeteners noma i-sugar alcohol.

Okwamanje, i-green leaf stevia iyifomu elicutshungulwa kancane. Yenziwe ngamaqabunga e-stevia aphelele omisiwe futhi aphansi.

Yize umkhiqizo weqabunga eliluhlaza ngokujwayelekile ubhekwa njengefomu elimsulwa, awufundisiswa kahle njengezikhangiso ezimsulwa noReb A. Ngokunjalo, ucwaningo luyashoda ngokuphepha kwalo.

UStevia uyisiphuzi esinamakholori angu-zero. Izinhlobo zezohwebo zivame ukucutshungulwa kakhulu futhi zixutshwe namanye amaswidi.

Ukuphepha nokulandelwa kukaStevia

I-Steviol glycosides, okuyizicucu ezenziwe nge-stevia ezinjengeReb A, yaziwa njengephephile yi-Food and Drug Administration (FDA), okusho ukuthi ingasetshenziswa emikhiqizweni yokudla futhi ithengiswe e-United States ().

Ngakolunye uhlangothi, izinhlobo ezinamakhasi aphelele kanye nezicucu ze-stevia ezingavuthiwe okwamanje azivunyelwe yi-FDA ukuthi isetshenziswe emikhiqizweni yokudla ngenxa yokushoda kocwaningo ().

Ama-ejensi okulawula afana ne-FDA, iScientific Committee on Food (SCF), kanye ne-European Food Safety Authority (i-EFSA) bachaza ukwamukelwa kwansuku zonke okwamukelekayo kwama-steviol glycosides kuze kufike ku-1.8 mg ngekhilogremu lesisindo somzimba (4 mg ngekg) () .

Ukuphepha kukaStevia kubantu abathile

Yize imikhiqizo eminingi ye-stevia ngokuvamile ibonwa njengephephile, olunye ucwaningo lukhombisa ukuthi lesi sinamitha se-zero-khalori singathinta abantu abathile ngokuhlukile.

Ngenxa yezimo zezempilo noma ubudala, amaqembu ahlukahlukene angafuna ukukhumbula kakhulu ukudla kwawo.

Isifo sikashukela

Ungathola i-stevia ilusizo uma unesifo sikashukela - kepha qaphela ukuthi yiluphi uhlobo ongalukhetha.

Olunye ucwaningo lukhombisa ukuthi i-stevia ingaba yindlela ephephile nephumelelayo yokusiza ukuphatha amazinga kashukela egazini kubantu abane-type 2 diabetes.

Eqinisweni, isifundo esisodwa esincane kubantu abayi-12 abanalesi simo sikhombisile ukuthi ukusebenzisa lesi sinambitheka eceleni kwesidlo kuholele ekwehleni okukhulu emazingeni kashukela egazi uma kuqhathaniswa neqembu elilawulayo elinikezwe inani elilinganayo lesitashi sommbila ().

Ngokunjalo, ucwaningo lwamaviki ayisishiyagalombili kumagundane anesifo sikashukela luphawule ukuthi ukukhishwa kwe-stevia kunciphise amazinga kashukela egazini ne-hemoglobin A1C - uphawu lokulawulwa kashukela wesikhathi eside - ngamaphesenti angaphezu kwama-5% uma kuqhathaniswa namagundane adlisa ukudla kokulawula ().

Khumbula ukuthi ukuhlanganiswa okuthile kwe-stevia kungaqukatha ezinye izinhlobo zeswidi - kufaka phakathi i-dextrose ne-maltodextrin - ezingakhuphula amazinga kashukela egazini (11,).

Ukusebenzisa le mikhiqizo ngokulinganisela noma ukukhetha ukukhishwa kwe-stevia emsulwa kungasiza ukugcina amazinga kashukela ejwayelekile egazini uma unesifo sikashukela.

Ukukhulelwa

Ubufakazi obunqunyelwe bukhona ekuphepheni kwe-stevia ngesikhathi sokukhulelwa.

Kodwa-ke, izifundo zezilwane ziphakamisa ukuthi lesi sinambitheka - ngesimo se-steviol glycosides esinjengoReb A - asithinti kabi imiphumela yokuzala noma yokukhulelwa uma sisetshenziswa ngokulinganisela ().

Ngokwengeziwe, ama-ejensi ahlukahlukene okulawula abheka i-steviol glycosides ephephile kubantu abadala, kufaka phakathi ngesikhathi sokukhulelwa ().

Noma kunjalo, ucwaningo ngeqabunga eliphelele le-stevia kanye nokukhishwa okuluhlaza kukhawulelwe.

Ngakho-ke, ngesikhathi sokukhulelwa, kungcono ukunamathela emikhiqizweni evunyelwe yi-FDA equkethe ama-steviol glycosides kuneqabunga eliphelele noma imikhiqizo eluhlaza.

Izingane

UStevia angasiza ekunciphiseni ukusetshenziswa koshukela okungeziwe, okungasiza kakhulu izingane.

Ngokwe-American Heart Association (AHA), ukudla kakhulu ushukela ongeziwe kungakhuphula ubungozi bezingane zesifo senhliziyo ngokuguqula amazinga e-triglyceride nele-cholesterol kanye nokufaka isandla ekuzuzeni isisindo ().

Ukushintshanisa ushukela owengeziwe we-stevia kungahle kunciphise lezi zingozi.

I-Steviol glycosides efana neReb A ivunyelwe yi-FDA. Kodwa-ke, kubaluleke kakhulu ukuqapha ukungena kwezingane ().

Lokhu kungenxa yokuthi kulula kakhulu ukuthi izingane zifinyelele kumkhawulo wansuku zonke owamukelekayo we-stevia, okuyi-1.8 mg ngekhilogremu yesisindo somzimba (4 mg ngekg ngayinye) kubo bobabili abadala nezingane ().

Ukukhawulela ukusetshenziswa kwengane yakho ukudla nge-stevia namanye ama-sweeteners, afana noshukela, kungasiza ukuvimbela imiphumela emibi emibi nokusekela impilo yonke.

I-Steviol glycosides efana neReb A yamukelwa yi-FDA - ngenkathi amaqabunga aphelele kanye nokukhishwa okuluhlaza kungenjalo. UStevia angathinta amaqembu athile ngokuhlukile, kufaka phakathi izingane, abesifazane abakhulelwe, nabantu abanesifo sikashukela.

Imiphumela emibi ye-stevia

Yize ngokuvamile kwaziwa njengokuphephile, i-stevia ingadala imiphumela emibi kwabanye abantu.

Isibonelo, okunye ukubuyekezwa kuphawulwe ukuthi iziphuzo ezingena-zero-calorie ezinjenge-stevia zingaphazamisa ukugxila kwamathumbu amabacteria anenzuzo, adlala indima enkulu ekuvikeleni izifo, ekugayeni nasekuzivikeleni komzimba (,,).

Olunye ucwaningo kubantu abangama-893 luthole ukuthi ukuhlukahluka kwamagciwane esiswini kungathinta kabi isisindo somzimba, i-triglycerides, namazinga we-HDL (okuhle) ama-cholesterol - izici eziyingozi zesifo senhliziyo ().

Olunye ucwaningo luye lwasikisela ukuthi i-stevia namanye ama-sweeteners ama-zero-calorie angaholela ekutheni usebenzise ama-calories amaningi usuku lonke ().

Isibonelo, ucwaningo olulodwa emadodeni angama-30 luthole ukuthi ukuphuza isiphuzo esinoshukela esenziwe nge-stevia kubangele ababambiqhaza ukuthi badle kakhulu emuva kosuku, uma kuqhathaniswa nokuphuza isiphuzo esinoshukela ().

Ngaphezu kwalokho, ukubuyekezwa kwezifundo eziyisikhombisa kwathola ukuthi ukusetshenziswa okujwayelekile kwama-zero-calorie sweeteners afana ne-stevia kungasiza ekwandiseni isisindo somzimba kanye nomjikelezo okhalweni ngokuhamba kwesikhathi ().

Ngokwengeziwe, imikhiqizo ethile ene-stevia ingahle ifake iziphuzo ezinoshukela njenge-sorbitol ne-xylitol, okungama-sweeteners kwesinye isikhathi ahlotshaniswa nezinkinga zokugaya ukudla kubantu abazwelayo ().

UStevia anganciphisa nomfutho wegazi namazinga kashukela egazi, okungahle kuphazamise imithi esetshenziselwa ukwelapha lezi zimo ().

Ukuze uthole imiphumela emihle, yenza isilinganiso sokudla kwakho futhi ucabangele ukunciphisa ukusetshenziswa uma uhlangabezana neminye imiphumela emibi.

UStevia angahle aphazamise amazinga akho amabhaktheriya esiswini anempilo. Ngokuphikisana, obunye ubufakazi buze buveze nokuthi bungakhuphula ukudla futhi bunikele kwisisindo somzimba esiphakeme ngokuhamba kwesikhathi.

Okubalulekile

I-Stevia iyi-sweetener engokwemvelo exhunyaniswe nezinzuzo eziningi, kufaka phakathi amazinga kashukela aphansi.

Ngenkathi ukukhishwa okucwengisisiwe kuthathwa njengokuphephile, ucwaningo kumaqabunga aphelele nemikhiqizo eluhlaza luyashoda.

Uma isetshenziswa ngokulinganisela, i-stevia ihlotshaniswa nemiphumela emibi embalwa futhi ingathatha indawo enkulu koshukela ocwengekile.

Gcina ukhumbula ukuthi kudingeka olunye ucwaningo ngalesi sinamanzi.
