Deta Yolonjezedwa, Koma Yoperewera Kwambiri
Stevia ndi mtundu wa zomera zomwe zili ndi masamba okoma kwambiri. Masambawa agwiritsidwa ntchito kukometsera zakumwa komanso monga gawo la shuga ku Central ndi South America (kuphatikizapo Texas, Arizona, ndi New Mexico). Kwa zaka mazana ambiri, mafuko a ku Paraguay, Brazil ndi Bolivia agwiritsira ntchito masamba a stevia kuti azisangalala ndi mankhwala ndi mankhwala. Kuchotsa Stevia kungakhale kokoma 300 kuposa shuga (poyerekeza ndi Splenda, yomwe nthawi zambiri imakhala yokoma kuposa shuga).
Chinthu chovuta kwambiri (mwinamwake) chokhudza stevia ndi chakuti sichikhudza ma shuga a magazi. M'mawu ena, ndi zotsika kwambiri zotsekemera zotsekemera ndipo zingakhale zothandiza kwa odwala matenda ashuga.
Kuchita kwa Stevia
Tisanalowe ku zotsatira za thanzi komanso nkhani zina zozungulira stevia, tiyeni tizithamangitse: Kodi Stevia amamva bwanji? Chabwino, kuti ndidziwe, ine ndinachita zanga zenizeni-zasayansi mayeso olawa. Zotsatira zanga zimagwirizana ndi kuvomerezana kwachidziŵitso komwe stevia, poyerekeza ndi shuga, amatenga nthawi yaitali kuti "zokoma" zokoma zikhazikike ndipo kukoma kokoma kumatenga nthawi yaitali. Mitundu ina ya stevia ikuwoneka kuti ili ndi mbuyo pambuyo pake yomwe ndi licorice kapena pang'ono. Zotsatira zake siziri, zokha, zosasangalatsa; koma akhoza kuthandizana ndi zokoma zina kuti apange kukoma kosamvetseka.
Kodi Stevia Ali Otetezeka?
M'zaka za m'ma 1980, maphunziro ochuluka adatuluka omwe ankanena za mavuto omwe angakhalepo okhudzidwa ndi stevia. Kafukufuku wina anapeza kuti monga stevia anathyola thupi, chimodzi mwa zigawozi zingayambe khansa.
Kuwonjezera apo, maphunziro asonyeza zotsatira zosiyana. Mu 2008, kufufuza kwina kunabwera pofufuza kafukufuku wakale wonena za stevia omwe amawoneka otetezeka. Chotsatira chachikulu (chomwe chinayambitsa chiwonetsero cha FDA cha "palibe chotsutsa") chinali chakuti gulu linalake la stevia (Rebaudioside A, onani m'munsimu kuti mudziwe zambiri) munalibe ngozi zotetezedwa zogwirizana nazo.
Komabe, ziyenera kuzindikiranso kuti ena mwa maphunzirowa adalandira ndalama kuchokera kwa Cargill, kampani yomwe ikufuna kupanga cholowa cha stevia chochokera ku stevia.
Mapindu a Stevia Health
Nkhani zabwino zowonjezera stevia zinabwera pamene maphunziro angapo (kachiwiri, omwe nthawi zambiri amalimbikitsidwa ndi mafakitale) adasonyeza kuti okometsera otchedwa stevia osangomva kukoma kokoma, komanso amathandizanso anthu kusintha malungo a insulini (omwe amathandizira matenda a shuga) komanso ngakhale kuthandizira ndi kuthamanga kwa magazi (kuthamanga kwa magazi). Inde, sikokwanira kudziwika za zotsatira za stevia kudziwa ngati izi ziridi zoona, koma mudzawona maphunziro awa omwe amatchulidwa kawirikawiri pa webusaiti ya stevia.
Mfundo yofunika: Pakalipano, palibe deta yokwanira kuti tithe kugwiritsira ntchito stevia kuti tipeze kuthamanga kwa magazi, shuga, matenda otupa mafupa kapena china chirichonse. Samalani powerenga kafukufuku pa stevia. Kafukufuku wina amagwiritsa ntchito mitundu yosiyana siyana ya zomera, njira zowonjezera zosiyana ndi zigawo zosiyanasiyana za zomera kusiyana ndi zina, zomwe zimapangitsa kuti zikhale zovuta kuyerekeza deta kudutsa maphunziro.
Stevia ndi Antioxidants
Stevia ndi antioxidant. Antioxidants amathandiza thupi lanu kulimbana ndi kuwonongeka kwazowonjezereka kwaulere (ndi kuchepetsa ukalamba wosasunthika waufulu). Stevia, monga ndi zomera zonse, ali ndi antioxidants angapo.
Izi zimapangitsa stevia (kuganiza kuti ndi otetezeka) kutsogolo kwa zotsekemera zina zomwe ziribe zopindulitsa zoteteza antioxidants.
Ndale za Stevia
Apa ndi pamene zimakhala zovuta. Stevia adavomerezedwa kwa kanthaŵi ku Japan, China, Israel, ndi kwina kulikonse. Koma ku US, stevia sanamvomerezedwe (ngakhale kuti mitundu ina ya okometsera otchedwa stevia yavomerezedwa). Panali phunziro ku mapeto a zaka za m'ma 1980 zomwe zinapangitsa stevia kukhala oletsedwa ndi FDA pokhapokha atatchulidwa ngati choonjezera (ndipo analetsedwa ku Ulaya). A FDA akuyenera kugwa pansi pa makampani angapo akuyesera kugulitsa stevia monga chowonjezera chakudya mmalo mwa supplement.
Kuwonongeka uku kwachititsa mabungwe ndi nkhani kudandaula za FDA kuteteza makampani a shuga mwa kupewa stevia. Uwu unali udindo wa stevia mpaka kumapeto kwa 2008.
Rebiana: Stevia Agwira Ovomerezedwa (Mtundu Wa)
Rebiana ndi dzina la sweetener ya zero-calorie yopangidwa kuchokera ku stevia. Makamaka, Rebiana wapangidwa kuchokera ku steviol glycoside rebaudioside A (Reb-A). Izi, makamaka, zimachokera ku gawo lina la chomera cha stevia. Chakumapeto kwa chaka cha 2008, a FDA adalembera kalata ya "Regiana" kuti ikhale chakudya chowonjezera. Kumbukirani kuti "palibe chokanika" kwa Rebiana sichikutanthauza kuti zolemba zonse za stevia zatsimikiziridwa ndi FDA, Rebiana yekha ndi ena omwe amachokera ku stevia omwe amatsata ndondomeko yowotchulidwa m'nyuzipepala ya FDA.
Truvia ndi PureVia
Truvia ndi PureVia ndiwo maina a sweeteners omwe ali ndi Rebiana (Reb-A). Coke ndi Pepsi ali ndi zakumwa zatsopano zomwe zimakhala ndi zokometsera zowonongeka monga Sprite Green , SoBe Lifewater, Trop 50 ndi zakumwa zina.
Pansi pa Stevia
Stevia ndi wokometsetsa ndipo amachita ntchito yabwino popanga zokoma. Ili ndi tanthauzo losiyana, choncho yesani ilo musanaligule zambiri. Pofika pa chitetezo, Rebiana yekha ndi amene avomerezedwa ndi FDA. A FDA ndi mabungwe omwewo ku Ulaya akupitiriza kuletsa stevia mu zakudya. Chifukwa chomwe Rebiana amavomerezera ndi chifukwa chakuti ndi stevia yoyeretsedwa kwambiri. Kwa nthawiyi, a FDA akuti "musachoke ku stevia mu zakudya, kupatula Rebiana." Ponena za mphamvu za machiritso a stevia, ganizirani za mtundu wonse pa nthawi ino. Pali sizinthu zambiri zokhazokha zomwe stevia amachiza matenda a shuga, matenda oopsa kwambiri kapena matenda ena.
