Ngelixa sizama ukubonelela ngeenkcukacha ezichanekileyo nezihlaziywayo esikholelwa ukuba ziya kuba luncedo kuwe, iForbes Health ayiqinisekisi kwaye ayinakuqinisekisa ukuba naluphi na ulwazi olunikiweyo luphelele kwaye alubonisi okanye iziqinisekiso malunga nokuchaneka okanye ukusetyenziswa kwayo.
Iintlobo ezimbini eziqhelekileyo zeti ye-caffeine, iti eluhlaza kunye neti emnyama, zenziwe ngamagqabi eCamellia sinensis. Umahluko phakathi kwezi ziti zimbini liqondo le-oxidation ezihamba emoyeni phambi kokuba zomiswe. Ngokuqhelekileyo, iti emnyama ivundisiwe (ithetha ukuba iimolekyuli zeswekile zichithwa ngeenkqubo zendalo zekhemikhali) kodwa iti eluhlaza ayikho. I-Camellia sinensis yaba ngumthi weti wokuqala ukulinywa e-Asia kwaye ibisetyenziswa njengesiselo kunye namayeza amawaka eminyaka.
Zomibini iti eluhlaza kunye nemnyama iqulethe i-polyphenols, iikhompawundi zezityalo ezine-antioxidant kunye ne-anti-inflammatory properties zifundwe. Qhubeka ufunde ukuze ufunde ngakumbi malunga neenzuzo eziqhelekileyo kunye nezohlukileyo zezi tea.
UDanielle Crumble Smith, i-dietitian ebhalisiweyo kwi-Vanderbilt Monroe Carell Jr. Isibhedlele saBantwana kwindawo yaseNashville, uthi indlela iti eluhlaza kunye ne-black tea ecutshungulwa ngayo ibangela ukuba uhlobo ngalunye luvelise iikhompawundi ezizodwa ze-bioactive.
Olunye uphando lubonisa ukuba i-antioxidants yeti emnyama, i-theaflavins kunye ne-thearubigins, inokunceda ukuphucula uvakalelo lwe-insulin kunye nokulawula iswekile yegazi. "Olunye uphando lubonise ukuba itiye emnyama ihambelana ne-cholesterol ephantsi [kunye] nokuphucula ubunzima kunye namazinga eshukela egazi, oko ke kunokuphucula iziphumo ze-cardiovascular," kusho ugqirha wangaphakathi oqinisekisiweyo webhodi uTim Tiutan, uDkt. kunye nomncedisi kagqirha ohambayo kwiZiko loMhlaza weSikhumbuzo Sloan-Kettering kwisiXeko saseNew York.
Ukusela iikomityi ezingaphezu kwezine zeti emnyama ngosuku kunciphisa umngcipheko wesifo senhliziyo, ngokutsho kophononongo lwe-2022 olupapashwe kwi-Frontiers in Nutrition. Nangona kunjalo, ababhali baqaphele ukuba ukusela iikomityi ezingaphezu kwezine zeti (iikomityi ezine ukuya kwezintandathu ngosuku) kunokunyusa umngcipheko wesifo senhliziyo [3] Yang X, Dai H, Deng R, et al. Umbutho phakathi kokusetyenziswa kweti kunye nokuthintela isifo senhliziyo: ukuphononongwa okucwangcisiweyo kunye ne-dose-response meta-analysis. Imida yezondlo. 2022;9:1021405.
Uninzi lweenzuzo zezempilo zeti eluhlaza zibangelwa kumxholo ophezulu we-catechin, iipolyphenols, eziyi-antioxidants.
Ngokutsho kweZiko leSizwe lezoNyango oluFanelekileyo kunye nokuHlanganisa kwiZiko leSizwe lezeMpilo, i-tea eluhlaza ngumthombo obalaseleyo we-epigallocatechin-3-gallate (EGCG), i-antioxidant enamandla. Iti eluhlaza kunye namacandelo ayo, kubandakanywa ne-EGCG, ifundelwe amandla abo okuthintela izifo ze-neurodeergenerative ezifana nesifo se-Alzheimer's.
"I-EGCG kwi-green tea isanda kufunyaniswa ukuba iphazamise i-tau protein tangles kwingqondo, ebaluleke kakhulu kwi-Alzheimer's disease," kusho i-RD, i-dietitian ebhalisiweyo kunye nomlawuli weCure Hydration, i-plant-based electrolyte drink blend. USarah Olszewski. “Kwisifo sika-Alzheimer, iprotein ye-tau ithi ngokungaqhelekanga idibane ibe ziintsinga, ibangele ukufa kweeseli zengqondo. Ngoko ukusela iti eluhlaza [kusenokuba] yindlela yokuphucula ukusebenza kwengqondo nokunciphisa umngcipheko wesifo sika-Alzheimer.”
Abaphandi bafunda iziphumo zeti eluhlaza kwixesha lokuphila, ngakumbi ngokunxulumene nolandelelwano lwe-DNA olubizwa ngokuba yi-telomeres. Ubude be-telomere obufutshane bunokunxulunyaniswa nokuncipha kwexesha lokuphila kunye nokwanda kokugula. Uphononongo lwamva nje lweminyaka emithandathu olupapashwe kwiiNgxelo zeNzululwazi ezibandakanya ngaphezulu kwe-1,900 abathathi-nxaxheba bafikelela kwisigqibo sokuba ukusela iti eluhlaza kubonakala kunciphisa amathuba okuba mfutshane kwe-telomere xa kuthelekiswa nokusela ikofu kunye neziselo ezithambileyo [5] Sohn I, Shin C. Baik I Association of green tea , ikofu, kunye nokusetyenziswa kwesiselo esithambileyo kunye neenguqu ze-longitudinal kwi-leukocyte telomere ubude. Iingxelo zenzululwazi. 2023;13:492. .
Ngokubhekiselele kwiipropati ezithile ezichasene nomhlaza, uSmith uthi iti eluhlaza inokunciphisa umngcipheko womhlaza wolusu kunye nokuguga kwangaphambi kwexesha. Uphononongo lwe-2018 olupapashwe kwiphephancwadi i-Photodermatology, i-Photoimmunology kunye ne-Photomedicine ibonisa ukuba ukusetyenziswa kwe-topical ye-polyphenols yeti, ngokukodwa i-ECGC, inokunceda ukukhusela imisebe ye-UV ukuba ingene esikhumbeni kwaye ibangele uxinzelelo lwe-oxidative, inokunciphisa umngcipheko womhlaza wesikhumba [6] Sharma P. , Montes de Oca MC, Alkeswani AR njl. I-polyphenols yeTea inokuthintela umhlaza wesikhumba obangelwa yi-ultraviolet B. I-Photodermatology, i-photoimmunology kunye ne-photomedicine. 2018;34(1):50–59. . Nangona kunjalo, izilingo ezininzi zeklinikhi zabantu ziyafuneka ukuze kuqinisekiswe ezi ziphumo.
Ngokophononongo lwe-2017, ukusela iti eluhlaza kunokuba neenzuzo zengqondo, kubandakanya ukunciphisa uxhalaba kunye nokuphucula inkumbulo kunye nokuqonda. Olunye uphononongo lwe-2017 lugqibe ukuba i-caffeine kunye ne-L-theanine kwi-tea eluhlaza ibonakala iphucula ukugxininiswa kunye nokunciphisa ukuphazamiseka [7] Dietz S, i-Dekker M. Imiphumo ye-tea ehlaza ye-phytochemicals kwi-mood and cognition. Uyilo lwangoku lwamachiza. 2017; 23 (19): 2876-2905. .
"Uphando olongezelelweyo luyafuneka ukuze kuqinisekiswe ubungakanani obupheleleyo kunye neendlela zeziphumo ze-neuroprotective ze-tea eziluhlaza ebantwini," ulumkisa uSmith.
"Kubalulekile ukuba uqaphele ukuba ezininzi iziphumo zecala zihambelana nokusetyenziswa ngokugqithiseleyo (kwe-tea eluhlaza) okanye ukusetyenziswa kwe-green tea supplements, enokuthi iqulethe i-concentrations ephezulu kakhulu ye-bioactive compounds kune-tea ephuhliweyo," kusho uSmith. Kubantu abaninzi, ukusela iti eluhlaza ngokumodareyitha kukhuselekile. Nangona kunjalo, ukuba umntu uneengxaki ezithile zempilo okanye usebenzisa amayeza, kusoloko kucetyiswa ukuba adibane nogqirha ngaphambi kokuba enze utshintsho olukhulu kwindlela asebenzisa ngayo iti eluhlaza.
I-SkinnyFit Detox ayinalaxative kwaye iqulethe i-13 metabolism-boosting superfoods. Xhasa umzimba wakho ngale tea yepesika enencasa yedetox.
Ngelixa zombini iti emnyama neluhlaza iqulethe i-caffeine, iti emnyama idla ngokuba nomxholo ophezulu wecaffeine, kuxhomekeke kwindlela yokusetyenzwa kunye neendlela zokusela, ngoko kunokwenzeka ukuba kunyuke ubukhali, utshilo uSmith.
Kuphononongo luka-2021 olupapashwe kwijenali yeSayensi yezeMpilo yaseAfrika, abaphandi bagqibe kwelokuba ukusela ikomityi enye ukuya kwezine zeti emnyama ngosuku, kunye nokutya kwecaffeine ukusuka kwi-450 ukuya kwi-600 milligrams, kunokunceda ukuthintela ukudakumba. Iziphumo zeti emnyama kunye nokusetyenziswa kwe-caffeine kumngcipheko wokudakumba phakathi kwabathengi beti emnyama. IiNzululwazi zezeMpilo zaseAfrika. 2021;21(2):858–865. .
Obunye ubungqina bubonisa ukuba iti emnyama inokuphucula kancinane impilo yamathambo kwaye incede ukunyusa uxinzelelo lwegazi kubantu abanoxinzelelo lwegazi oluphantsi emva kokutya. Ukongezelela, i-polyphenols kunye ne-flavonoids kwi-tea emnyama inokunceda ukunciphisa uxinzelelo lwe-oxidative, ukuvuvukala kunye ne-carcinogenesis, uDkt Tiutan uthe.
Uphononongo luka-2022 oluphantse lube ngama-500,000 amadoda kunye nabasetyhini abaneminyaka engama-40 ukuya kwengama-69 bafumene ubudlelwane obuphakathi phakathi kokusela iikomityi ezimbini okanye ngaphezulu zeti emnyama ngosuku kunye nomngcipheko ophantsi wokufa xa kuthelekiswa nabantu abangaseliyo iti. UPawulos [9] Inoue - Choi M, Ramirez Y, Cornelis MC, et al. Ukusetyenziswa kweti kunye nonobangela kunye nokufa okuthe ngqo e-UK Biobank. Iingxelo zoNyango lwangaphakathi. 2022;175:1201–1211. .
"Olu lolona phando lukhulu lolo hlobo lwayo ukuya kuthi ga ngoku, kunye nexesha elilandelwayo elingaphezu kweminyaka elishumi kunye neziphumo ezilungileyo malunga nokunciphisa ukufa," kusho uDkt Tiutan. Nangona kunjalo, iziphumo zophando ziphikisana neziphumo ezixubileyo kwizifundo ezidlulileyo, wongezelela. Ukongezelela, uDkt. Tiutan waphawula ukuba abathathi-nxaxheba babemhlophe ngokuyinhloko, ngoko uphando olongezelelweyo lufunekayo ukuze uqonde ngokupheleleyo umphumo weti emnyama ekufeni kwabantu ngokubanzi.
Ngokutsho kweThala leeNcwadi leSizwe leMithi yeZiko lezeMpilo leSizwe, iimali ezilinganiselweyo zeti emnyama (engekho ngaphezu kweekomityi ezine ngosuku) zikhuselekile kubantu abaninzi, kodwa abafazi abakhulelweyo nabancancisayo akufanele basele ngaphezu kweekomityi ezintathu ngosuku. Ukusebenzisa ngaphezu kokucetyiswayo kunokubangela intloko ebuhlungu kunye nokubetha kwentliziyo okungaqhelekanga.
Abantu abaneemeko ezithile zonyango banokuba neempawu eziba mandundu ukuba basela iti emnyama. ILayibrari yeSizwe yezoNyango yase-US ikwathi abantu abanezi meko zilandelayo kufuneka basele iti emnyama ngononophelo:
UDkt Tiutan uncoma ukuthetha nodokotela wakho malunga nendlela iti emnyama enokuthi idibanise ngayo namayeza athile, kubandakanywa i-antibiotics kunye neyeza lokudakumba, i-asthma kunye ne-epilepsy, kunye nezinye izongezo.
Zombini iintlobo zeti zineenzuzo zempilo ezinokubakho, nangona iti eluhlaza ingaphezulu kancinci kuneti emnyama ngokweziphumo ezisekwe kuphando. Izinto zobuqu zinokukunceda ukuba wenze isigqibo sokuba ukhethe iti eluhlaza okanye emnyama.
Iti eluhlaza idinga ukwenziwa ngokucokisekileyo ngakumbi emanzini apholileyo kancinci ukunqanda incasa ekrakrayo, ngoko ke inokulungela ngakumbi abantu abakhetha inkqubo yotywala ngokucokisekileyo. NgokukaSmith, iti emnyama kulula ukuyipheka kwaye inokumelana namaqondo obushushu aphezulu kunye namaxesha ahlukeneyo okunyuka.
Ukhetho lokungcamla lukwamisela ukuba yeyiphi iti efanelekileyo kumntu othile. Iti eluhlaza idla ngokuba nencasa entsha, enemifuno okanye yemifuno. Ngokutsho kukaSmith, kuxhomekeke kwimvelaphi kunye nokucutshungulwa, incasa yayo inokusuka kwi-sweet and nutty to salty and little astringent. Iti emnyama inencasa etyebileyo, evakala ngakumbi ukusuka kwimalty kunye neswiti ukuya kwiziqhamo kunye nomsi kancinci.
USmith ucebisa ukuba abantu abanovelwano kwi-caffeine banokukhetha iti eluhlaza, ene-caffeine ephantsi kuneti emnyama kwaye inokubonelela nge-caffeine epholileyo ngaphandle kokuvuselela kakhulu. Wongeza ukuba abantu abafuna ukutshintshela kwikofu baye kwiti banokufumanisa ukuba umxholo ophezulu we-caffeine weti emnyama wenza ukuba utshintsho lube luncinci.
Kwabo bafuna ukuphumla, uSmith uthi iti eluhlaza iqulethe i-L-theanine, i-amino acid ekhuthaza ukuphumla kunye nokusebenza ngokubambisana ne-caffeine ukuphucula umsebenzi wokuqonda ngaphandle kokubangela i-jitters. Iti emnyama nayo iqulethe i-L-theanine, kodwa ngamanani amancinci.
Nokuba ukhetha luphi uhlobo lweti, uya kuvuna izibonelelo zempilo. Kodwa kwakhona khumbula ukuba iiti zinokwahluka ngokubanzi kungekuphela nje kwi-brand yeti, kodwa nakwimixholo ye-antioxidant, ukuhlaziyeka kweti kunye nexesha lokunyuka, ngoko kunzima ukwenza ngokubanzi malunga neenzuzo zeti, utsho uGqr Tiutan. Waphawula ukuba olunye uphando kwiipropathi ze-antioxidant zeti emnyama zivavanywe iindidi ezingama-51 zeti emnyama.
"Ngokwenene kuxhomekeke kuhlobo lwetiyi emnyama kunye nohlobo kunye nokulungelelaniswa kwamagqabi etiyi, anokutshintsha inani lale mixube equlethwe [kwitiyi]," kusho uTutan. Ke bobabini banamanqanaba ahlukeneyo omsebenzi we-antioxidant. Kunzima ukuthetha ukuba iti emnyama ineenzuzo ezizodwa ngaphezu kweti eluhlaza ngenxa yokuba ubudlelwane phakathi kwezi zibini buyahluka kakhulu. Ukuba kukho umahluko konke konke, mhlawumbi mncinci.”
