Ithi elihlaza liyaziwa ukuthi linempilo enhle ngenxa ye-antioxidants equkethe, kodwa futhi ine-caffeine. Uma uzwela nge-caffeine noma ufuna ukujabulela indebe yetiyi eluhlaza ebusuku, uzobe usathola izinzuzo zezempilo uma ukhetha itiye elihlaza elibomvu? Ucwaningo lwezocwaningo lubonisa ukuthi uzokwenza.
Yini Enkulu Ngamaqanda Ahlaza?
Izinzuzo ze-tea eluhlaza zivela kuma- phytochemicals , okuyizinto zemvelo zamakhemikhali ezitholakala ezitshalweni.
Amanye alawo maqhamuka e-phytochemicals, abizwa ngokuthi i-flavanols, anika itiye eluhlaza okuningi kwamandla alo okuvimbela i-antioxidant futhi kuye kwaba ukugxila kocwaningo oluhlukahlukene. I-caffeine nayo i-phytochemical, kodwa ayihlangene nhlobo nemisebenzi yalawo ma-antioxidants.
Ukuphuza itiye elihlaza njalo kucatshangwa ukuthi kungcono empilweni yakho, kodwa ukwethembeka, kunzima ukwazi ukuthi kuhle kangakanani kuwe. Ucwaningo olulodwa ngo-2015 lwaluthola ukuthi abaphuzi betiya abanohlaza babenengozi encane yezifo zesibindi uma kuqhathaniswa nabantu abangaphuzi itiye elihlaza, kodwa ucwaningo oluningi luyadingeka ukuze bathole ukuthi ukuphuza itiye elihlaza kunciphisa lo mngcipheko noma uma abantu abaphuza itiye abavuthiwe ukuba neminye imikhuba enempilo ethinte imiphumela. Ezinye iziphakamiso zitshela ukuthi ama-tea extracts angaba yinhle enhliziyweni yakho futhi akhuthaze inani eliphansi lokunciphisa isisindo, kodwa lezo zisekelwe ekuthatheni i-tea tea 'amaphilisi' kunokuba uphuze itiye elihlaza.
Ithimba Elihlaza Lama-decaffein Liyilinganisa Kanjani Namaqabunga Okujwayelekile?
Izinqubo ezikhipha i-caffeine etikini eluhlaza zibuye zisuse ezinye ze-polyphenols, kodwa hhayi zonke zazo.
Ngokwesinye isifundo esashicilelwe ngo-2003, okuqukethwe kwe-flavanol yama-teas avamile kuhluka kusuka ku-21.2 kuya ku-103.2 mg / g (ama-milligram ngegremu), kanti okuqukethwe kwe-flavanol yezinhlayiya eziluhlaza okwesibhakabhaka kusuka ku-4.6 kuya ku-39.0 mg / g.
Amanani we-antioxidant ahlukahluka kusuka ku-728 ukuya ku-1,686 iTrolox equals / g yetiyizikhathi ezivamile futhi kusuka ku-507 kuya ku-845 Isilinganiso se-Trolox / gram for teas decaffeinated.
Ngakho ngenkathi kunciphisa ama-flavanols, umsebenzi we-antioxidant awulahlekile ngokuphelele. Kodwa ngaphesheya kwalokho, kunzima ukutshela ukuthi i-decaffeinated tea ehlaza iyasiza kakhulu kubantu ngoba izifundo eziningi zetiyi eziluhlaza zenziwa ngezilwane zelabhu kunabantu. Kodwa kunezifundo ezimbalwa ezenziwa nabathintekayo abangabantu ukuthi basisize ukuthi siqonde uma itiye eluhlaza isebenza.
Imiphumela Yezifundo Ukusebenzisa I-Tea Green Deaffeinated
Ucwaningo olwanyatheliswa ngonyaka ka-2011 luhlolwe i-decaf green tea extracts (elilingana nezinkomishi ezingaba ngu-6 kuya kwezingu-8 zesitsha esishisayo ngosuku) kubantu abakhuluphele noma abakhuluphele. Abacwaningi bathola ukuthi lapho abahlanganyeli bethatha izithako, babe nokwanda emazingeni e-epigallocatechin gallate (i-EGCG yiyona eyaziwa kakhulu yamakhakishi e-green tea) futhi yalahlekelwa isisindo.
Olunye ucwaningo olwakhicilelwe ngo-2010 lwabheka itiye le-decaf nokulahlekelwa isisindo kulabo besifazane ababesinda emdlalweni webelevuza webele. Kwakukhona ukulahleka kwesisindo phakathi nezinyanga eziyisithupha, kodwa hhayi okwanele ukuba kube nokubaluleka kwesibalo. Kodwa, abesifazane abathatha itiye elihlaza babenezikhukhula kwi-HDL yabo ye-cholesterol (enhle).
Ucwaningo olusanda kutholakala ngetayisi eluhlaza lukhishwe ngonyaka ka-2014 futhi lusetshenziselwa umkhiqizo we-tea oluhlaza okhiqiza ithemba ukuthi kuzoba usizo kubantu besifazane ababengaba nezinguquko ze-papillomavirus yabantu kanye nezinguquko zeseli lomlomo wesibeletho ezingathuthuka emdlalweni.
Ngeshwa, itiye elihlaza alibonakalanga ukunikeza noma yikuphi ukuvimbela nhlobo.
Izwi elivela
Ukuphuza itiye eluhlaza kunamanje kunamandla okuvimbela i-antioxidant futhi kungasiza kancane ngokulahlekelwa isisindo, kodwa kungakhathaliseki ukuthi kwenzekani okwengeziwe empilweni yakho akucaci. Noma kunjalo, ayikho ikhalori futhi ingaba yingxenye yokudla okunempilo.
Kubalulekile ukwazi ukuthi itiye eluhlaza i-decaffeinate ingase ingabi ne-caffeine ngokuphelele, ngakho-ke uma uzwa i-caffeine, ingase ikuthinte.
