Eyaziwa ngokusemthethweni ngokuthi i-epigallocatechin gallate, i-EGCG iwuhlobo lwenhlanganisela esekwe esitshalweni ebizwa nge-catechin. Ama-Catechins angase aphinde ahlukaniswe abe yiqembu elikhulu lezinhlanganisela zezitshalo ezaziwa ngokuthi ama-polyphenols.
I-EGCG namanye ama-catechin ahlobene asebenza njengama-antioxidants anamandla angavikela emonakalweni wamaselula obangelwa ama-radicals mahhala.
Ama-radicals wamahhala ayizinhlayiya ezisebenzayo kakhulu ezakheka emzimbeni wakho ezingalimaza amaseli akho lapho izinombolo zawo ziba phezulu kakhulu. Ukudla ukudla okune-antioxidant ephezulu njengama-catechin kungasiza ukunciphisa ukulimala kwama-radical mahhala.
Ukwengeza, ucwaningo lubonisa ukuthi ama-catechin afana ne-EGCG anganciphisa ukuvuvukala futhi avimbele izimo ezithile ezingapheli, ezihlanganisa nesifo senhliziyo, isifo sikashukela, kanye nomdlavuza.
I-EGCG ikhona ngokwemvelo ekudleni okuningana okusekelwe ezitshalweni kodwa futhi iyatholakala njengesengezo sokudla esivame ukuthengiswa ngendlela yokukhipha.
Ngokwemvelo itholakala ekudleni okuhlukahlukene
I-EGCG cishe yaziwa kakhulu ngendima yayo njengenhlanganisela enkulu esebenzayo etiyeni eliluhlaza.
Eqinisweni, izinzuzo eziningi zezempilo ezihlotshaniswa nokuphuza itiye elihlaza zivame ukubizwa ngokuthi okuqukethwe kwe-EGCG.
Nakuba i-EGCG itholakala kakhulu etiyeni eliluhlaza, ikhona futhi ngamanani amancane kokunye ukudla, okufana nalokhu:
- Itiye: itiye eluhlaza, emhlophe, e-oolong namnyama
- Izithelo: ama-cranberries, ama-strawberries, amajikijolo, ama-kiwi, ama-cherries, amapheya, amapentshisi, ama-apula, nama-avocados
- Amantongomane: ama-pecans, ama-pistachios, nama-hazelnuts
Nakuba i-EGCG iyi-catechin ecwaningwe kakhulu futhi enamandla, ezinye izinhlobo ezifana ne-epicatechin, i-epigallocatechin, ne-epicatechin 3-gallate zingase zinikeze izinzuzo ezifanayo. Ngaphezu kwalokho, eziningi zazo zitholakala kabanzi ekunikezeni ukudla.
Iwayini elibomvu, ushokoledi omnyama, okusanhlamvu okusanhlamvu, neningi lezithelo izibonelo ezimbalwa zokudla okunikeza umthamo omkhulu wamakatekhini othuthukisa impilo .
Ishubhu lokuhlola, isilwane, kanye nezifundo ezimbalwa zabantu zibonisa ukuthi i-EGCG inikeza izinzuzo eziningi zezempilo, okuhlanganisa ukuvuvukala okuncishisiwe, ukuncipha kwesisindo, kanye nempilo engcono yenhliziyo nengqondo.
Ekugcineni, ucwaningo olwengeziwe luyadingeka ukuze kuqondwe kangcono ukuthi i-EGCG ingasetshenziswa kanjani njengethuluzi lokuvimbela noma ukwelashwa kwezifo, nakuba idatha yamanje iyathembisa.

- I-Antioxidant ne-anti-inflammatory effect
Iningi letiye le-EGreen likhipha isimangalo sodumo se-EGCG livela kumandla ayo okulwa ne-antioxidant namandla okunciphisa ukucindezeleka nokuvuvukala.
Ama-radicals wamahhala ayizinhlayiya ezisebenza kakhulu ezingadala umonakalo kumaseli akho. Ukukhiqizwa kwe-radical yamahhala ngokweqile kuholela ekucindezelekeni kwe-oxidative.
Njenge-antioxidant, i-EGCG ivikela amangqamuzana akho emonakalweni ohambisana nokucindezeleka okwenziwe nge-oxidative futhi icindezela umsebenzi wamakhemikhali abangela ukuvuvukala akhiqizwa emzimbeni wakho, njenge-tumor necrosis factor-alpha (TNF-alpha).
Ukucindezeleka nokuvuvukala kuhlobene nezifo ezihlukahlukene ezingapheli, ezihlanganisa umdlavuza, isifo sikashukela nesifo senhliziyo.
Ngakho-ke, imiphumela elwa nokuvuvukala kanye ne-antioxidant ye-EGCG kucatshangwa ukuthi ingenye yezizathu eziyinhloko zezinhlelo zayo ezibanzi zokuvimbela izifo.
- Impilo yenhliziyo
Ucwaningo lusikisela ukuthi i-EGCG etiyeni eliluhlaza ingase isekele impilo yenhliziyo ngokunciphisa umfutho wegazi, i-cholesterol, nokunqwabelana koqweqwe lwemithambo yegazi—zonke izici eziyingozi ezinkulu zesifo senhliziyo.
Ocwaningweni lwamasonto angu-8 kubantu abangu-33, ukuthatha u-250 mg we-EGCG equkethe itiye elihlaza ekhishwe nsuku zonke kwaphumela ekunciphiseni okukhulu kwe-LDL (okubi) ngo-4.5%.
Ucwaningo oluhlukile kubantu abangu-56 luthole ukwehla okukhulu komfutho wegazi, i-cholesterol, kanye nezimpawu zokuvuvukala kulabo abathatha umthamo wansuku zonke wama-379 mg wetiye elihlaza elikhishwe ngaphezu kwezinyanga ezi-3.
Nakuba le miphumela ikhuthaza, ucwaningo olwengeziwe luyadingeka ukuze uqonde kangcono ukuthi i-EGCG etiyeni eliluhlaza inganciphisa kanjani ingozi yesifo senhliziyo.
- Ukuncipha kwesisindo
I-EGCG ingase futhi ikhuthaze ukulahlekelwa isisindo, ikakhulukazi uma ithathwa kanye ne-caffeine ngokwemvelo etholakala etiyeni eliluhlaza.
Nakuba imiphumela eminingi yocwaningo kumphumela we-EGCG esisindweni ingaguquki, olunye ucwaningo lokubheka lwesikhathi eside luphawule ukuthi ukudla izinkomishi ezi-2 (ama-ounces angu-14.7 noma 434 ml) zetiye eliluhlaza ngosuku kwakuhlotshaniswa namafutha omzimba aphansi nesisindo.
Ucwaningo olwengeziwe lwabantu luhlangene luthole ukuthi ukuthatha u-100-460 mg we-EGCG kanye no-80-300 mg we-caffeine okungenani amaviki angu-12 kuhlobene nokuncipha okukhulu kwesisindo kanye nokwehliswa kwamafutha omzimba.
Noma kunjalo, izinguquko zesisindo noma ukwakheka komzimba azibonakali njalo lapho i-EGCG ithathwa ngaphandle kwe-caffeine.
- Impilo yobuchopho
Ucwaningo lwangaphambili lubonisa ukuthi itiye elihlaza elikhishwe i-EGCG lingase libe neqhaza ekuthuthukiseni ukusebenza kwamangqamuzana ezinzwa kanye nokuvimbela izifo zobuchopho eziwohlokayo.
Kwezinye izifundo, imijovo ye-EGCG ithuthukise kakhulu ukuvuvukala, kanye nokululama nokuvuselelwa kwamangqamuzana e-neural kumagundane anokulimala komgogodla.
Ukwengeza, izifundo zokuhlola eziningi kubantu zathola ukuxhumana phakathi kokudla okuphezulu kwetiye eliluhlaza kanye nengozi encishisiwe yokuncipha kobuchopho obuhlobene nobudala, kanye nesifo i-Alzheimer's and Parkinson. Nokho, idatha etholakalayo ayihambisani .
Ngaphezu kwalokho, kusalokhu kungacaci ukuthi i-EGCG ngokuqondile noma mhlawumbe ezinye izingxenye zamakhemikhali zetiye eliluhlaza zinale miphumela.
Ucwaningo olwengeziwe luyadingeka ukuze kuqondwe kangcono ukuthi i-EGCG ingavimbela noma yelaphe ngempumelelo izifo zobuchopho eziwohlokayo kubantu.
