Emakhulwini eminyaka, isiko letiye laseShayina lendabuko belithatha ukufakwa okusha kwamaqabunga e-Camellia sinensis njengomuthi wokuvikela wansuku zonke, futhi isayensi yesimanje ekugcineni isifinyelela lokho ogogo nomkhulu bakho ababekwazi kakade. E-Japan, eShayina, eYurophu nase-United States, izifundo ezinkulu ze-epidemiological zibika ngokungaguquki ukuthi abantu abaphuza itiye nsuku zonke bavame ukukhombisa izimpawu eziphansi zobudala bezinto eziphilayo kanye nengozi encishisiwe yezifo ezihlobene nobudala, kusukela ezikhalazweni zenhliziyo nemithambo yegazi kuya ekwehleni kwengqondo. Inzuzo yokuphila isikhathi eside yetiye ivame ukubalelwa kuma-polyphenols ezitshalo ezilwa nokucindezela kwe-oxidative kanye nokuvuvukala okungapheli, okuvame ukubhekwa njengezimbangela ezimbili eziyisisekelo zokuguga kwamaseli. Phakathi kwalo mndeni omkhulu weziphuzo, impikiswano nge-红茶 (itiye elimnyama) ngokumelene ne-绿茶 (itiye eliluhlaza) ihlala ingumbuzo ovame kakhulu abathengi abawubuza lapho behlela uhlelo lokuhlala kahle. Ngenxa yokuthi zombili lezi ziphuzo zabelana ngeqabunga elifanayo lezitshalo kodwa zilandela izindlela zokucubungula ezihluke kakhulu, ziletha izinhlanganisela ezisebenzayo ezihlukile futhi, ngokulandelana, izinzuzo zezempilo ezihambisanayo emzimbeni wakho. Lesi sihloko sihlaziya isayensi engemuva kohlobo ngalunye, siqhathanisa imiphumela yazo yokulwa nokuguga ngemininingwane, futhi sichaza indlela yokukhetha inkomishi yansuku zonke efanele imigomo yakho ethile yezempilo. Ekugcineni, ngizokwethula uhla lwemikhiqizo esezingeni eliphezulu evela eChangzhou Qingzhitang Tea Company Limited, umkhiqizi onamasimu etiye aphethwe nguye, amaqoqo amasha okuvuna, kanye nemigqa yokucubungula eqinisekisiwe esiza ukuqinisekisa ukusha kwezakhamzimba okuncike kulezi zinhlanganisela ezithuthukisa impilo. Uma uncamela ukuhlola imisebenzi yethu yokuthenga obala kanye nokucwaningwa kwefektri ngqo, iwebhusayithi ye-HOME yenkampani inikeza isithombe esiphelele sokuthi itiye lethu likhula futhi liphathwa kanjani kusukela engadini kuya esikhwameni.

Ishayina eliluhlaza licutshungulwa ngokuxubha okuncane, okugcina iqoqo elicebile lama-polyphenols aziwa ngokuthi ama-catechins, futhi phakathi kwalezi i-molecule ebaluleke kakhulu i-epigallocatechin gallate, evame ukubizwa nge-EGCG. I-EGCG ingelinye lama-antioxidants emvelo anamandla kakhulu acwaningiwe kuze kube manje, ekhombisa amandla okunciphisa ama-free radicals, ukusekela ukulungiswa kwe-DNA, nokulawula izindlela zokuvuvukala ezingeni lamaseli. Lapho amaqabunga eshayina eliluhlaza efakwa emoyeni noma etshiswa epanini ngokushesha ngemva kokuvunwa, ukwakheka kwawo kwasekuqaleni kwama-catechin kuhlala kungashintshile kakhulu, okunikeza lokho abacwaningi abakubiza ngokuthi isiphuzo "esigcwele ama-catechin" esisebenza ngendlela emangalisayo ekulweni nokucindezela kwe-oxidative. Izifundo zabantu ezenziwa emiphakathini yase-Asia lapho ishayina eliluhlaza liyisisekelo sokudla zihlobanisa ngokuphindaphindiwe ukusetshenziswa okuphezulu nobude be-telomere obude, okuyisinye sezimpawu ezibaluleke kakhulu zebhayoloji, hhayi iminyaka yokuzalwa. Kubantu abafuna inkomishi ehlanzekile, enemifino, nenotshani encane enokugcinwa okuphezulu kwama-polyphenol, ishayina eliluhlaza elisezingeni eliphezulu limelela isengezo esihle sokulwa nokuguga kunoma yiluphi uhlelo lwansuku zonke.

Itiye elimnyama lithatha uhambo oluhluke ngokuphelele ngoba amaqabunga awo ahlangana nomoya ngokugcwele ngemuva kokuvunwa ngenqubo yokugingqika nokuvutshelwa okuguqula ama-catechin okuqala abe yizinhlayiyana ezinkulu nezimnyama ezibizwa nge-theaflavins ne-thearubigins. Ama-theaflavins, anikeza itiye elimnyama umbala walo ogqamile onsundu ngokuliphuzi, akheka lapho ama-catechin alula ehlangana ndawonye ngesikhathi sokuhlangana nomoya, futhi lezi zinhlanganisela zibonisa izici ezinamandla zokulwa nama-oxidant, zokulwa nokuvuvukala, nezokuvikela imizwa yobuchopho eziyingqayizivele kutiye elimnyama. Ama-thearubigins, ngakolunye uhlangothi, anomthelela ekwakheni isiphuzo esinsundu ngokujulile futhi abonakala esekela impilo yokugaya ngokusebenzisana kahle nesistimu yezinto eziphilayo ezincane ezihlala ngaphakathi kwamathumbu akho. Lesi sinyathelo sokuhlangana nomoya sinciphisa inani le-EGCG eliphelele endebeni, kodwa sakha umndeni omusha ngokuphelele wama-polyphenols avame ukumuncwa kangcono ngasemathunjini aphansi, futhi ucwaningo lwanamuhla lubonisa ukuthi anemithelela yawo enamandla kumetabolism nasekusebenzeni kobuchopho. Ukuqonda umehluko phakathi kukatiye eliluhlaza netiye elimnyama kubalulekile ngoba kukusiza uqaphele ukuthi asikho isiphuzo esivele "singcono" ngokwaso; kunalokho, ngasinye sinikeza amathuluzi amakhemikhali ahambisanayo angafaniswa nezinto ozibeka phambili empilweni yakho.

Iphuzu elibaluleke kakhulu mayelana nokwakheka kwe-polyphenol ukuthi i-oxidation ishintsha kokubili ikhemistri kanye, ngandlela thile, nokutholakala kwezinto ezisebenzayo eziphilayo, yingakho iqoqo letiye elilinganiselayo libaluleke kangaka ekudleni okulwa nokuguga. Ososayensi futhi bathole ukuthi amathumbu omuntu aqukethe ama-enzyme akwazi ukuguqula ama-catechin athile etiye eliluhlaza abe yizinto eziphilayo ezinjengasetiye elimnyama, okusho ukuthi ukuphuza itiye eliluhlaza kungase kukhiqize ngokungaqondile ezinye zezinhlanganisela ezinenzuzo ezifanayo ezitholakala ngokwemvelo etiyeni elimnyama. Ngaleso sikhathi, inqubo yokuvutshelwa etiyeni elimnyama idala ama-theaflavin asinda ekugayeni ngendlela emangalisayo, okuwavumela ukuba afinyelele ikholoni lapho asekela khona amagciwane anenzuzo okuhlanganisa nezinhlobo ezaziwayo ze-Bifidobacteria ne-Lactobacilli. Ngakho-ke, kungakhathaliseki ukuthi ulandela ukushaya okusheshayo kwama-antioxidant okuvela ekuphuzweni okusha okuluhlaza noma uncamela ukusekelwa kokugaya okubushelelezi, okunambitheka okujulile kwetiye elimnyama elivutshiwe, zombili lezi zindlela ziholela endaweni efanayo yokuguga kwamaseli okunempilo. Uma uthenga emthonjeni othembekile olawula yonke iketanga lokuhlinzeka, ungathembela ekutholeni lonke uhla lwama-polyphenol kuwo wonke amavuno, futhi lokho kuyisiqinisekiso i-Qingzhitang eyakhe idumela layo kuso iminyaka eminingi.

Kuzo zonke izindlela ezihlongozwayo zokulwa nokuguga zetiye eliluhlaza, ubufakazi obunamandla kakhulu bugxile kuma-telomere, izivalo zokuvikela ezisemaphethelweni ama-chromosome ezifushane njalo lapho iseli lihlukaniseka. Ezifundweni eziningi ezinkulu zokubheka, abaphuzi betiye eliluhlaza njalo batholakala benama-telomere amade uma kuqhathaniswa nabangaphuzi bentanga elifanayo, okusikisela ukuthi ama-catechin ansuku zonke angase anciphise iwashi lemvelo ezingeni lamangqamuzana. Umshayeli oyinhloko walo mphumela ubonakala uyikhono le-EGCG lokunciphisa ingcindezi ye-oxidative ngaphakathi kwe-nucleus, ukuvimbela ama-radical amahhala ekulimazeni imicu ye-DNA nokusheshisa ukuguguleka kwama-telomere. Ngaphezu kwalokho, ama-polyphenol etiye eliluhlaza alawula umsebenzi we-enzyme ebizwa nge-telomerase, futhi nakuba ubufakazi bokuqala buvela kakhulu kumamodeli aselabhorethri, isiqondiso semiphumela sithanda ngokungaguquki ukuvikela i-genome. Kulabo bethu abakhathazekile ngokuguga ngaphambi kwesikhathi kwesikhumba, imisipha, nezitho, ukugcina ubuqotho be-DNA ngokuthatha ama-antioxidant ansuku zonke ngokulingene kungenye yezindlela ezethembeke kakhulu esingazisebenzisa, futhi inkomishi yetiye eliluhlaza lekhwalithi ephezulu ingena kahle kulelo hlelo.

Ukuvuvukala kungenye insika esemqoka yenqubo yokuguga, evame ukubizwa ngokuthi "i-inflammaging," ngoba ukuvuvukala okungapheli okusezingeni eliphansi kulimaza izicubu ngokuthula phakathi neminyaka futhi kusheshisa ukuqala kwezimo ezihlobene nokuguga. Ama-catechin etiye eliluhlaza, ikakhulukazi i-EGCG, aziwa ngokucindezela umsebenzi wamaprotheni avusa ukuvuvukala njenge-tumor necrosis factor-alpha nama-interleukins, ngaleyo ndlela athulise umlilo ongapheli obangela izifo eziningi zokuguga. Ngesikhathi esifanayo, lawa ma-polyphenol akhulisa izivikelo zangaphakathi zama-antioxidant ngokusebenzisa izindlela ezifana ne-Nrf2 ezisiza umzimba wakho ukuthi ukhiqize ama-enzyme avikelayo usuku lonke. Ucwaningo olunamandla oluvela ezizweni zaseJapane asebekhulile lubonisa ukuthi labo abaphuza izinkomishi ezimbalwa zetiye eliluhlaza nsuku zonke babonisa amazinga aphansi ezimpawu zokuvuvukala futhi benza kahle ezivivinyweni zokusebenza komzimba kunontanga yabo engaphuzi. Le nhlanganisela, ukuncipha kokucindezeleka kwe-oxidative kuhlangene nokuvuvukala okuthulile, ichaza ukuthi kungani itiye eliluhlaza lihlale lixhunyaniswa nezingozi eziphansi zesifo senhliziyo nemithambo yegazi, imidlalo eminingana yomdlavuza, nokungasebenzi kahle kwe-metabolic ezibuyekezweni ezihlelekile kanye nokuhlaziywa kwe-meta. Uma izinhloso zakho zempilo siqu zitshekela ekuvikelweni okujwayelekile kwama-antioxidant, ukunwebeka kwesikhumba, nokugcinwa kwamaseli, itiye eliluhlaza elitholakala kahle njenge-Longjing ephambili edayiswa yi-Qingzhitang kungaba ukukhetha okuhle kakhulu kwansuku zonke.

Nakuba itiye eliluhlaza livame ukuthatha indawo ephambili kwezempilo, itiye elimnyama lifanelwe ukunakwa ngokulinganayo ngoba ama-molecule alo ayingqayizivele i-theaflavin anikeza izinzuzo ezivikela ubuchopho kanye nezinzuzo ze-metabolism ezingenziwa ngama-catechin etiye eliluhlaza ngendlela efanayo. Ucwaningo lwezilwane kanye nokuhlolwa kwemitholampilo kusikisela ukuthi ama-theaflavin angawela umngcele wegazi nobuchopho futhi asize ekulondolozeni ukusebenza kwengqondo ngokunciphisa ukwakheka kwe-amyloid plaque nokusekela ukugeleza kwegazi okunempilo ezicutshini zemizwa. Ngaphezu kwalokho, lezi zinhlanganisela zithuthukisa ukuzwela kwe-insulin kanye ne-glucose metabolism, okwenza itiye elimnyama libe umlingani obalulekile ikakhulukazi kubantu ababhekana nezinguquko ze-metabolism ezivame ukuhambisana nokuguga. Ezinhlakeni ezimbalwa zesikhathi eside, ukuphuza itiye elimnyama nsuku zonke kwakuhlotshaniswa nezinga eliphansi kakhulu le-type 2 diabetes kanye namaphrofayili e-fasting glucose angcono esikhathini sokulandelela seminyaka eyishumi, ngisho nangemva kokulungisa ukudla kanye nezici zendlela yokuphila. Uma kucatshangelwa konke lokhu, itiye elimnyama linikeza uhlobo oluqondile kakhulu lokuvikela ubuchopho obugugayo kanye ne-metabolism egugayo, okulenza libe ngaphezu komkhuba wokuzijabulisa wasekuseni.

Itiye elimnyama libuye lidlale indima ehlukile ekusekeleni ukusebenza kwenhliziyo nemithambo yegazi kanye ne-microbiome yamathumbu, kokubili okubalulekile ekugugeni okunempilo. Ama-theaflavins nama-thearubigins ayo kuye kwaboniswa ukuthi athuthukisa ukusebenza kwe-endothelial, esiza ulwelwesi lwangaphakathi lwemithambo yegazi ekukhululekeni nasekulawuleni umfutho wegazi ngokwemvelo, okuhumusha ekuncipheni kwengcuphe yokushaywa unhlangothi nesifo senhliziyo kubantu abaphuza isikhathi eside. Ngakolunye uhlangothi, ama-polyphenols amakhulu e-polymeric atiye elimnyama asebenza njengama-prebiotics, okondla amakholoni amabhaktheriya anenzuzo ekholoni futhi akhuthaze i-microbiome ehlukahlukene kakhulu ekhiqiza ama-short-chain fatty acids avikelayo afana ne-butyrate. Indawo yamathumbu enempilo, yona, isekela ukuzivikela okuqinile, ukumuncwa okungcono kwezakhamzimba, kanye nokuthuthuka kwemizwelo ngokusebenzisa i-gut-brain axis, konke lokhu okuncipha ngokuguga uma kungasekelwa. Izifundo ze-epidemiological e-United Kingdom, lapho ukusetshenziswa kwetiye elimnyama kuphezulu kakhulu, zithole ukuthi ukuphuza izinkomishi ezimbili noma ngaphezulu ngosuku kuxhumene nokufa okunciphile kwazo zonke izimbangela esikhathini esiyishumi leminyaka, okugcizelela ukubaluleka kwangempela kwale miphumela yaselabhorethri. Kafushane, nakuba isisekelo socwaningo lwetiye elimnyama sincane kancane kunaleso setiye eliluhlaza, sikhula ngokushesha, futhi ubufakazi obutholakale kuze kube manje busikisela ukuthi zombili iziphuzo zisebenza kahle kakhulu, nakuba ngemizila yezinto eziphilayo ehambisanayo esebenza kangcono kakhulu uma zisetshenziswa ndawonye kunokuba zisetshenziswe zodwa.

Kulesi sikhathi, ubufakazi besayensi bucacile ukuthi kokubili itiye eliluhlaza kanye netiye elimnyama kunikeza ukusekelwa okuqinile kokuguga okunempilo, ngakho-ke isinqumo sokugcina kufanele sihambisane nokuthanda kwakho ukunambitha, ukubekezelela i-caffeine, kanye nezinjongo zakho ezithile zezempilo. Uma ukukhathazeka kwakho okuyinhloko kuhilela amandla aphezulu e-antioxidant, ukususa ama-free radical, kanye nokuvikela isikhumba ne-DNA ekucindezelekeni kwe-oxidative, itiye eliluhlaza lekhwalithi ephezulu eligcwele ama-catechin lingase libe umlingani wakho oqinile. Ngakolunye uhlangothi, uma ugxile ekuguquguqukeni kwe-metabolic, ukunethezeka kokugaya ukudla, ukuphila isikhathi eside kobuchopho, kanye nokusebenza kwenhliziyo okuzinzile, iphrofayili eyingqayizivele ye-theaflavin yetiye elimnyama ingase ikusize kangcono nsuku zonke. Izinga le-caffeine nalo liyahlukahluka, njengoba itiye eliluhlaza ngokuvamile linikeza i-caffeine encane kune-tiye elimnyama elivela ku-cultivar efanayo, nakuba kokubili kuselula kakhulu kunekhofi noma i-espresso, futhi kokubili kunikeza i-amino acid epholile i-L-theanine eyenza imiphumela yezinto ezivuselelayo ibe mnene. Ngaphezu kwalokho, ukunambitha kubaluleke kakhulu ekuzinzeni kwesikhathi eside, ngoba amanothi athambile, anotshani, futhi amnandi kancane etiye eliluhlaza i-Longjing elihle awakwazi ukufaka esikhundleni sokujula okunama-malt, okucebile, nokunosizi kwetiye elimnyama i-Keemun, futhi ukujabulela kwakho kubikezela ngokuqondile ukuthi uzohlala uzinzile yini inyanga ngemuva kwenyanga. Abaphuzi betiye abaningi abaphumelelayo empeleni bashintshana phakathi kwalezi zinhlobo ezimbili usuku lonke, basebenzisa itiye eliluhlaza ekuseni ukuze bathole amandla ahlanzekile nokuvikelwa, bese bedlulela kutiye elimnyama eline-caffeine ephansi noma elibilisiwe ntambama ukuze bathole ukunethezeka kokugaya ukudla kanye ne-metabolic. I-Qingzhitang yakhe uhlu lwayo lonke ukuze ihloniphe leli qiniso, inikeza ukukhethwa okuhlanganisiwe kwakho kokubili itiye eliluhlaza nelimnyama lekhwalithi ephezulu ukuze zonke izindlela zokuphila, izinjongo zezempilo, kanye nokuthanda ukunambitha kuthole umlingani wakho ophelele ku-oda elilodwa.

Ukuze uvule amandla aphelele okulwa nokuguga afihlwe ngaphakathi kwamaqabunga akho etiye, izinga lokushisa lokufaka kanye nesikhathi sokucwilisa kubaluleke kakhulu kunalokho abantu abaningi abaphuza itiye abangakucabangi, ngoba amanzi abilayo angawonakalisa kalula ama-catechins abuthakathaka futhi enze isiphuzo esibabayo nesibabayo. Etiyeni eliluhlaza, indlela efanele ukushisa amanzi asemthonjeni amasha noma ahlungiwe afinyelele cishe ku-75 kuya ku-80 degrees Celsius, bese ucwilisa amaqabunga imizuzu emibili kuya kwemithathu, ukhiphe isiphuzo esimnandi nesinombala wemifino ngaphandle kokubaba okweqile. Itiye elimnyama, ngokuphambene, lisebenza kahle kakhulu ngamanzi abila kakhulu cishe ku-95 kuya ku-100 degrees Celsius, licwiliswe imizuzu emithathu kuya kwemihlanu ukukhipha wonke amandla alo e-theaflavins ne-thearubigins kanye nalowo mkhuba ojulile we-malty. Ukusebenzisa cishe amagremu amabili kuya kwamathathu amaqabunga ngenkomishi engu-250 milliliter iyindawo enhle yokuqala, futhi yonke iphakethe le-Qingzhitang lifaka imiyalelo enemininingwane yokufaka itiye ehambisana ne-cultivar yangempela kanye nesitayela sokucubungula. Ucwaningo oluningi luphakamisa ukuthi ukuphuza phakathi kwezinkomishi ezimbili nezintathu zetiye elingafakwanga ushukela ngosuku kunikeza umthamo obalulekile womtholampilo wama-polyphenols, futhi kubalulekile ukukhumbula ukuthi ukwengeza ushukela noma ubisi kuzonciphisa eminye imiphumela enenzuzo ngokushintsha ukumuncwa, ngakho-ke zama ukujabulela itiye lihlanzekile futhi lingahlotshisiwe. Kulabo abazwela i-caffeine, izinguquko ezimbalwa ezilula zingagcina izinzuzo zempilo ngaphandle kokuphazamisa ubuthongo, kufaka phakathi ukukhetha ama-green tea amancane, avunwa ekuqaleni ane-caffeine encane ngokwemvelo, ukukhetha izinguqulo ezingenayo i-caffeine, noma ukukhawulela ukusetshenziswa kwetiye engxenyeni yokuqala yosuku. Njengoba ukukhishwa kwe-catechin kufinyelela umkhawulo wakho phakathi nemizuzu embalwa yokuqala yokucwilisa, ngisho nokupheka kwesibili okufushane kwamaqabunga afanayo kusacebisa inkomishi yakho ngama-antioxidants awusizo kuyilapho kunikeza ingxenye encane kuphela yokuqukethwe kwe-caffeine kwasekuqaleni.

Uma unquma ukutshala imali etiyeni leqiniso eliphezulu, umkhiqizo ongemuva leqabunga ubaluleke kakhulu, yingakho nje i-Qingzhitang izinikele kulezi zindinganiso zomthombo nokucutshungulwa. Kubathandi betiye eliluhlaza, i-West Lake Longjing, etholakala ezingadini zayo eziphakeme e-Zhejiang, isalokhu iyisincomo esiyinhloko ngoba ukunambitheka kwayo okugazingiwe ngesandla okufana nesihlahla samakinati kufanekisela isiko lasendulo lasebukhosini letiye eliluhlaza. Kubathandi bokunambitheka okumnyama, okunikezelayo, itiye elimnyama lase-Keemun, elivutshelwe ngokucophelela futhi lahlungwa endaweni yethu, linikeza "iphunga lase-Keemun" elidumile elaziswa abazi ngobuchwepheshe emhlabeni wonke, elinombala ofana noju newayini, elihambisana kahle nesidlo sokudla kusihlwa noma ubusuku obuthule. Yonke into ehlinzekwa yi-Qingzhitang ivunwa isanda kusikhathi sesizini esifanele futhi icutshungulwa emahoreni ambalwa ngaphansi kwezimo ezihlanzekile neziqinisekisiwe ukuze kugcinwe ama-polyphenols nama-aromatics enza lezi tiye zisebenze ngempela. Inkampani inezitifiketi eziqinile zekhwalithi ezihlanganisa ukuphepha kokudla, ukuhlolwa kwezinsalela, nokulandelelwa, futhi isizinda sayo sokukhiqiza esiphethwe yiyo siqinisekisa ukuthi akukho lutho oluhlala ezindaweni zokugcina zabathengisi phakathi lulahlekelwa amandla alo. Amakhasimende amaningi nabahloli abangochwepheshe bancome iphunga elicacile, ukupakishwa okungaguquguquki, nokusha okusobala kokulethwa ngakunye, futhi umkhiqizo uthole ukuqashelwa emibukisweni yezimboni eqinisekisa kabanzi umsebenzi wawo wobuciko. Ekuthengeni ngakunye, uthola amaqabunga aphelele hhayi uthuli, imihlahlandlela yokufaka enemininingwane, izinsuku zokuvuna, nokuzibophezela okucacile esigabeni sangempela, noma ngabe ukhetha uhlobo oluluhlaza olusha noma oluvuthiwe olumnyama.

Ukuthenga ku-Qingzhitang kusho ukuthi uthenga ngqo epulazini nasefektri, ngoba inkampani inezingadi zayo zetiye kanye nemigqa yokucubungula, iqeda noma yiziphi izinhlangano zesithathu ezingadingekile ezingalimaza izinga lamaqabunga. Isivuno ngasinye sihlelwa futhi silandelelwe kusukela ngesikhathi kukhiwa amaqabunga aqhakazile kuze kufike iphakethe elivaliwe emnyango wakho, okwenza i-Qingzhitang ikwazi ukuqinisekisa ukusha namandla okusebenza abathengi baphesheya kwezilwandle abavame ukukushoda lapho bethenga itiye lasesitolo elingaziwa ubudala. Ukupakisha kwaklanyelwe ukuvikela amaqabunga ekukhanyeni, emswakameni nasemoyeni, kuqinisekise ukuthi ama-polyphenols abucayi ahlala eqinile phakathi nokuthutha kwamazwe ngamazwe nokugcinwa isikhathi eside. Ukuthenga ngewebhusayithi yenkampani kulula, nokulethwa emhlabeni wonke kuyatholakala kubathengi baseNyakatho Melika, eYurophu, e-Australia naseMpumalanga Ephakathi, futhi ithimba liphendula ngokushesha kunoma yimuphi umbuzo mayelana nentela, isikhathi sokuthumela, noma amadokhumenti okufakazela. Abathengi abaqala ukuthenga bavame ukwamukelwa ngezipesheli zokwethula eziyisipesheli, njengamasethi okunambitha anesaphulelo akuvumela ukuthi unambithe kokubili okuluhlaza nokumnyama ngaphambi kokuzibophezela enanini elikhulu. Ukuze usebenzise lezi zinzuzo futhi uhlole uhla oluphelele lwemikhiqizo, ikhasi lekhaya leNkampani linikeza ukufinyelela okuqondile kukhathalogi yonke, isizinda senkampani, nezinketho zokuxhumana zemibuzo yokuthengisa ngobuningi. Emakethe egcwele itiye elingaguquguquki, ukuthola umkhiqizo omusha, oqinisekisiwe, futhi obhalwe ngokuthembekile ngqo kumkhiqizi iyona mpikiswano eyodwa ekhombisa ukuthi kufanele uzame i-Qingzhitang namuhla.

Ukuguga akusona umphumela wesakhi sokudla esisodwa, futhi iqiniso elingagwegwesi liwukuthi itiye lisebenza kahle kakhulu lapho liba yingxenye eyodwa ejabulisayo yendlela yokuphila ebanzi ehlanganisa ukudla okunempilo elinganiselayo, ukuzivocavoca umzimba njalo, ubuthongo obuvuselelayo, nokulawulwa kwengcindezi. Lokho itiye elikunikela ngakho ngendlela eyingqayizivele kulesi sibalo wumthamo wansuku zonke ophephile, ongabizi futhi omnandi wama-polyphenol asebenzayo avikela ekucindezelekeni kwe-oxidative kanye nokuvuvukala okusheshisa ngokuthule ukuguga kwemvelo. Kokubili itiye eliluhlaza kanye netiye elimnyama kufanele kube nendawo ehlala njalo emkhubeni wakho wansuku zonke, futhi ngokukhetha kokubili, uhlanganisa izinhlelo eziningi zomzimba kunalokho uhlobo olulodwa olungakwazi ukubhekana nakho lodwa. Uma ufuna ukulandela isayensi kuze kufike ekusetshenzisweni, khetha amaqabunga amasha, asezingeni eliphezulu, uwabilise ngendlela efanele, futhi uphuze izinkomishi ezimbili kuya kwezintathu ezingafakwanga ushukela nsuku zonke. Umkhiqizo ongemuva kwalawo maqabunga akuyona imininingwane encane, futhi ngenxa yaleso sizathu ngikukhuthaza ukuba uvumele i-Changzhou Qingzhitang inikeze isivikelo esisezingeni eliphezulu umzimba wakho owudingayo kuzo zonke izigaba zokuphila. Khetha itiye eliluhlaza elifana ne-Longjing yethu ukuze uthole isivikelo esinamandla sama-antioxidant, itiye elimnyama elifana ne-Keemun yethu ukuze uthole impilo ye-metabolic kanye namathumbu, noma uzihlanganise kupakethe lokunambitha elenzelwe wena ukuze uthole umkhuba wakho ophelele. Zama i-Qingzhitang namuhla futhi uguqule itiye lakho lansuku zonke lisuke kumkhuba olula libe ukutshalwa kwemali okusekelwe ebufakazini bekusasa elide, elinempilo futhi eliphilile kakhulu.

Zombili iziphuzo zinikeza izinzuzo eziphezulu zokulwa nokuguga, kodwa ngokusebenzisa izinto ezahlukene ezisebenzayo. Itiye eliluhlaza linikeza ama-catechins amaningi afana ne-EGCG asiza kakhulu ekwehliseni ukucindezeleka kwe-oxidative, ekusekeleni ubude be-telomere, nasekuvikeleni i-DNA, kanti itiye elimnyama linikeza ama-theaflavins ayingqayizivele asekela impilo yobuchopho, ukusebenza kwenhliziyo nemithambo yegazi, kanye nokulawulwa kwe-metabolism. Ukuze kutholakale isivikelo esiphelele, abantu abaningi bafaka zombili izinhlobo emasontweni abo kunokuba bakhethe eyodwa kuphela.

Yebo, impela. Ukuphuza izinkomishi ezimbili kuya kwezintathu zetiye nsuku zonke, kungaba uyahlukanisa phakathi kwetiye elimnyama neliluhlaza noma ukhethe uhlobo olulodwa, kuthathwa njengokuphephile futhi kuyinzuzo kubantu abadala abanempilo abaningi. Ukushintshanisa lezi zimbili kukunikeza kokubili ukuvikelwa okugcwele ngama-catechin kwetiye eliluhlaza kanye nezinzuzo ezicebile ngama-theaflavin zetiye elimnyama, futhi lezi zinhlobo ezimbili ziyahlangana kahle uma zingafakwanga ushukela.

Ucwaningo lukhombisa ukuthi imiphumela yezempilo engaguquguquki ivela kakhulu uma uphuza okungenani izinkomishi ezimbili kuya kwezintathu zetiye elingafakwanga ushukela nsuku zonke. Inkomishi eyodwa isewusizo, kodwa izinkomba zomtholampilo zokuncipha kokucindezeleka kwe-oxidative kanye nokuthuthuka kwezimpawu zenhliziyo ziyabonakala kakhulu uma uphuza ngokulinganiselayo futhi ngokuqhubekayo amaviki ambalwa. Imikhuba yansuku zonke engaguquguquki ibaluleke kakhulu kunokuphuza okukhulu ngezikhathi ezithile.

Ushukela ocwengiwe ngokusobala uyawukhubaza umzamo wokulwa nokuguga ngoba ukhuthaza ukuvuvukala kanye ne-glycation, ngakho-ke ukugwema ama-sweeteners kunconywa kakhulu ukuze kugcinwe inani lezempilo lokuphuza kwakho. Umthelela wobisi usaxoxwa ngawo, njengoba olunye ucwaningo lukhombisa ukuthi i-casein ingabopha ama-catechins futhi inciphise ukumuncwa kwawo, ikakhulukazi kutiye eluhlaza. Uma umgomo wakho uwukuthola ama-polyphenol amaningi, indlela ephephile ukuthi uphuze itiye lakho lingenalutho noma ngokucindezela kancane ulamula.

Ngokuvamile, itiye elimnyama liqukethe i-caffeine engaphezulu kancane kunetiye eliluhlaza ngenxa yenqubo ye-oxidation kanye nezinhlobo ezivame ukukhethwa, kodwa umehluko wangempela uyahluka kakhulu phakathi kwezinhlobo ezahlukene, kanti amanye amatiye aluhlaza aqukethe i-caffeine elingana noma engaphezulu kunamanye amatiye amnyama. Ukuba khona kwe-L-theanine kukho kokubili amatiye kunciphisa umphumela we-caffeine, kudale ukuqaphela okuzolile esikhundleni sokuxhuma. Ukuze uthole ukuzwela okukhulisiwe, khetha itiye lasentwasahlobo elivunwa ngaphambi kwesikhathi, phisa ngamanzi abandayo, futhi ugweme ngokuphelele i-caffeine ntambama sekwedlule isikhathi.

I-EGCG, isifinyezo se-epigallocatechin gallate, iyi-catechin etholakala kakhulu futhi enomsebenzi omkhulu kakhulu kwezempilo etholakala etiyeni eliluhlaza, futhi ibhekwa njengenye yezinto ezinamandla kakhulu zokudla ezilwa namagciwane emvelweni. Isebenza ngokunciphisa ama-free radicals, ivuselele izivikelo zomzimba ezilwa namagciwane, futhi inciphise ukuvuvukala okungapheli, konke lokhu okubalulekile ekunciphiseni ukuguga kwamangqamuzana. Ukugxila kwe-EGCG kuphezulu kakhulu emaqabungeni etiye eliluhlaza amasha, angaxutshiwe kancane, avunwe ngokucophelela futhi apakishwe ukuze kugcinwe amandla awo.

Yebo, ucwaningo olunzulu lwe-epidemiological, izivivinyo zomtholampilo, kanye nokuhlolwa kwaselabhorethri kusekela ukuxhumana phakathi kokusetshenziswa kwetiye njalo kanye nokuguga okunempilo. Izifundo zesikhathi eside zabantu e-Japan, e-China, e-United Kingdom, nakwezinye izifunda zihlobanisa ukuphuza itiye nsuku zonke nokuncipha kokufa kwenhliziyo, impilo engcono yemetabolism, kanye namazinga aphansi ezimpawu zokuguga kwemvelo. Nakuba itiye lodwa lingesona isiphethu sokuphila kwaphakade, izinzuzo zalo ziyafana futhi zibhalwe kahle kumaqembu amaningi ocwaningo azimele.

I-Qingzhitang yamukela zonke izinhlobo zetiye laseShayina ngoba izindlela ezahlukene zokucubungula zikhiqiza izinhlobo ezihlukene ze-polyphenol ezinomthelela omuhle ezingxenyeni ezihlukene zempilo. Ngokulima nokucubungula amatiye alo aluhlaza afana ne-Longjing namatiye amnyama abolile afana ne-Keemun, inkampani inikeza abathengi ithuba lokuzwa izinzuzo eziphelele zempilo ezivela emthonjeni oyedwa othembekile. Le ndlela ehlanganisiwe futhi ihlonipha ukuhlukahluka komlando wesiko letiye laseShayina, elalihlala lizisa kokubili ukusha nokuvutshelwa.

Kufanele uhlale ufuna umkhiqizi osebenza ngokuthenga ngqo epulazini, athumele amaqoqo amasha okuvuna, futhi anikeze izitifiketi ezisobala kanye nolwazi losuku lokuvuna. I-Qingzhitang ilawula izingadi zayo zetiye kanye nefektri yayo, okusho ukuthi yonke iphakethe lasuka esikhungweni sayo lisepakishini lesimanje elivikelayo elingavumeli umoya nomswakama. Uma umdayisi ekwazi ukulandelela iqabunga kusukela engadini kuze kufike enkomishini yakho futhi anikeze izitifiketi zekhwalithi ezicacile, ungathemba ukuthi ama-catechins nama-theaflavins angaphakathi asasebenza futhi asasebenza ngempumelelo.
