Ubusanzwe izwi nka epigallocatechin gallate, EGCG ni ubwoko bwibimera bishingiye ku bimera bita catechin. Catechins irashobora gushyirwa mubice binini byibihingwa bizwi nka polifenol.
EGCG hamwe na catechine bifitanye isano nayo ikora nka antioxydants ikomeye ishobora kurinda ibyangizwa na selile biterwa na radicals yubuntu.
Radikal yubusa ni uduce duto cyane twibumbiye mumubiri wawe ushobora kwangiza selile zawe mugihe umubare wazo ubaye mwinshi. Kurya ibiryo birimo antioxydants nka catechine birashobora kugabanya kwangirika kwubusa.
Byongeye kandi, ubushakashatsi bwerekana ko catechine nka EGCG ishobora kugabanya uburibwe no kwirinda indwara zimwe na zimwe zidakira, zirimo indwara z'umutima, diyabete, na kanseri zimwe.
EGCG ibaho mubisanzwe mubiribwa byinshi bishingiye ku bimera ariko biranaboneka nkinyongera yimirire isanzwe igurishwa muburyo bwikuramo.
Mubisanzwe biboneka mubiribwa bitandukanye
EGCG birashoboka ko izwi cyane kubera uruhare runini rwicyayi kibisi.
Mubyukuri, inyungu nyinshi zubuzima zijyanye no kunywa icyayi kibisi mubisanzwe byitirirwa EGCG.
Nubwo EGCG iboneka cyane mu cyayi kibisi, ibaho kandi muke mubindi biribwa, nka:
- Icyayi: icyatsi kibisi, cyera, oolong, nicyayi cyirabura
- Imbuto: cranberries, strawberry, blackberries, kiwis, cheri, amapera, pashe, pome, na avoka
- Imbuto: pecans, pisite, na hazelnuts
Mugihe EGCG ari catechine yakozwe cyane kandi ikomeye, ubundi bwoko nka epicatechin, epigallocatechin, na epicatechin 3-gallate irashobora gutanga inyungu zisa. Byongeye kandi, inyinshi murizo ziraboneka cyane mugutanga ibiryo.
Divayi itukura, shokora yijimye, ibinyamisogwe, n'imbuto nyinshi ni ingero nke zibyo kurya bitanga urugero rwinshi rwa catechine iteza imbere ubuzima.
Ikizamini-tube, inyamaswa, hamwe nubushakashatsi buke bwabantu byerekana ko EGCG itanga inyungu nyinshi mubuzima, harimo kugabanya umuriro, kugabanuka, hamwe nubuzima bwumutima nubwonko.
Ubwanyuma, ubushakashatsi burakenewe kugirango twumve neza uburyo EGCG ishobora gukoreshwa nkigikoresho cyo gukumira cyangwa kuvura indwara, nubwo amakuru agezweho atanga ikizere.

- Antioxidant n'ingaruka zo kurwanya inflammatory
Ibyinshi mu byayi bya EGreen bivamo EGCG kuba icyamamare biva mubushobozi bukomeye bwa antioxydeant ndetse nubushobozi bwo kugabanya imihangayiko no gutwika.
Radikal yubusa ni uduce duto cyane dushobora kwangiza selile zawe. Umusaruro ukabije wubusa utera guhagarika umutima.
Nka antioxydeant, EGCG irinda selile zawe kwangirika ziterwa na stress ya okiside kandi igahagarika ibikorwa byimiti itera imiti ikorwa mumubiri wawe, nkibibyimba biterwa na feri-alpha (TNF-alpha).
Guhangayika no gutwikwa bifitanye isano n'indwara zitandukanye zidakira, harimo kanseri, diyabete, n'indwara z'umutima.
Rero, anti-inflammatory na antioxidant ya EGCG batekereza ko ari imwe mu mpamvu zingenzi zituma ikoreshwa ryayo ririnda indwara.
- Ubuzima bwumutima
Ubushakashatsi bwerekana ko EGCG mu cyayi kibisi ishobora gushyigikira ubuzima bwumutima igabanya umuvuduko wamaraso, cholesterol, hamwe no kwegeranya plaque mumitsi yamaraso - ibintu byose bishobora gutera indwara z'umutima.
Mu bushakashatsi bwibyumweru 8 mubantu 33, gufata mg 250 za EGCG zirimo icyayi kibisi buri munsi byatumye kugabanuka kwa 4.5% bya cholesterol ya LDL (mbi).
Ubushakashatsi butandukanye bwakozwe ku bantu 56 bwerekanye ko igabanuka ryinshi ry’umuvuduko wamaraso, cholesterol, hamwe n’ibimenyetso byerekana umuriro mu bafata ikinini cya buri munsi cya mg 379 cy’icyayi kibisi mu mezi 3.
Nubwo ibisubizo bitera inkunga, birakenewe ubushakashatsi bwinshi kugirango twumve neza uburyo EGCG mu cyayi kibisi ishobora kugabanya ibyago byindwara z'umutima.
- Kugabanuka
EGCG irashobora kandi guteza imbere kugabanya ibiro, cyane cyane iyo ifashwe hamwe na cafine isanzwe iboneka mu cyayi kibisi.
Nubwo ibyinshi mubisubizo byubushakashatsi ku ngaruka za EGCG ku buremere bidahuye, ubushakashatsi bwakozwe mu gihe kirekire bwerekanye ko kunywa ibikombe bigera kuri 2 (14.7 ounci cyangwa 434 ml) byicyayi kibisi kumunsi bifitanye isano n’ibinure byo mu mubiri hamwe nuburemere.
Ubushakashatsi bw’inyongera bw’abantu bwerekanye ko gufata mg 100-460 mg ya EGCG hamwe na mg 80-300 za kafeyine byibura ibyumweru 12 bifitanye isano no gutakaza ibiro cyane no kugabanya ibinure byumubiri.
Nubwo bimeze bityo, impinduka muburemere cyangwa ibigize umubiri ntizigaragara mugihe EGCG ifashwe idafite cafeyine.
- Ubuzima bwubwonko
Ubushakashatsi bwambere bwerekana ko icyayi cyicyatsi kibisi EGCG gishobora kugira uruhare mugutezimbere imikorere yimikorere yimitsi no kwirinda indwara zubwonko bwangirika.
Mu bushakashatsi bumwe na bumwe, inshinge za EGCG zateje imbere cyane gutwika, ndetse no gukira no kuvugurura ingirabuzimafatizo mu mbeba zifite ibikomere by'umugongo.
Byongeye kandi, ubushakashatsi bwinshi bwakozwe ku bantu bwerekanye isano iri hagati yo gufata icyayi kibisi cyane ndetse no kugabanya ibyago byo kugabanuka kwubwonko biterwa n'imyaka, ndetse n'indwara ya Alzheimer na Parkinson. Ariko, amakuru aboneka ntaho ahuriye.
Ikirenzeho, ntibisobanutse neza niba EGCG byumwihariko cyangwa wenda nibindi bintu bigize imiti yicyayi kibisi bifite izo ngaruka.
Harakenewe ubushakashatsi bwinshi kugirango twumve neza niba EGCG ishobora gukumira cyangwa kuvura indwara zubwonko bwangirika mubantu.
