Poyamba ankadziwika kuti epigallocatechin gallate, EGCG ndi mtundu wa zomera zomwe zimatchedwa katechin. Makatekini akhoza kugawidwanso mu gulu lalikulu la zomera zomwe zimadziwika kuti polyphenols.
EGCG ndi makatekini ena okhudzana nawo amakhala ngati ma antioxidants amphamvu omwe angateteze ku kuwonongeka kwa ma cell chifukwa cha ma free radicals.
Ma radicals aulere ndi tinthu tating'onoting'ono tomwe timapanga m'thupi lanu zomwe zimatha kuwononga ma cell anu nambala yawo ikakwera kwambiri. Kudya zakudya zokhala ndi ma antioxidants ambiri monga makatekisimu kungathandize kuchepetsa kuwonongeka kwa ma free radicals.
Kuphatikiza apo, kafukufuku akuwonetsa kuti makatekini monga EGCG amatha kuchepetsa kutupa ndikuletsa matenda ena osachiritsika, kuphatikiza matenda amtima, shuga, ndi khansa zina.
EGCG imapezeka mwachilengedwe muzakudya zingapo zochokera ku mbewu koma imapezekanso ngati chowonjezera chazakudya chomwe chimagulitsidwa ngati chotsitsa.
Mwachilengedwe amapezeka muzakudya zosiyanasiyana
EGCG mwina imadziwika bwino chifukwa cha ntchito yake monga gawo lalikulu la tiyi wobiriwira.
M'malo mwake, maubwino ambiri azaumoyo okhudzana ndi kumwa tiyi wobiriwira nthawi zambiri amatchulidwa kuti ali ndi EGCG.
Ngakhale EGCG imapezeka kwambiri mu tiyi wobiriwira, imapezekanso pang'ono muzakudya zina, monga:
- Tiyi: tiyi wobiriwira, woyera, oolong ndi wakuda
- Zipatso: cranberries, sitiroberi, mabulosi akuda, kiwi, yamatcheri, mapeyala, mapichesi, maapulo ndi mapeyala.
- Mtedza: ma pecans, pistachios, ndi hazelnuts
Ngakhale kuti EGCG ndi katekisimu wofufuzidwa kwambiri komanso wamphamvu, mitundu ina monga epicatechin, epigallocatechin, ndi epicatechin 3-gallate ingapereke ubwino wofanana. Kuphatikiza apo, ambiri aiwo amapezeka kwambiri muzakudya.
Vinyo wofiira, chokoleti chakuda, nyemba, ndi zipatso zambiri ndi zitsanzo zochepa za zakudya zomwe zimapereka mlingo wochuluka wa makatekisimu olimbikitsa thanzi.
Mayesero, nyama, ndi maphunziro angapo aumunthu amasonyeza kuti EGCG imapereka ubwino wambiri wathanzi, kuphatikizapo kuchepetsa kutupa, kuchepa thupi, ndi thanzi labwino la mtima ndi ubongo.
Pamapeto pake, kafukufuku wambiri amafunika kuti amvetse bwino momwe EGCG ingagwiritsire ntchito ngati chida chopewera kapena kuchiza matenda, ngakhale kuti zomwe zilipo panopa zikulonjeza.
EGCG 50%
EGCG 98%
- Antioxidant ndi odana ndi yotupa zotsatira
Zambiri mwa tiyi wa EGreen amachotsa zonena za EGCG kutchuka zimachokera ku mphamvu yake yolimba ya antioxidant komanso kuthekera kochepetsa kupsinjika ndi kutupa.
Ma radicals aulere ndi tinthu tating'onoting'ono tomwe titha kuwononga ma cell anu. Kuchuluka kwa ma radicals aulere kumabweretsa kupsinjika kwa okosijeni.
Monga antioxidant, EGCG imateteza maselo anu kuti asawonongeke chifukwa cha kupsinjika kwa okosijeni ndikupondereza zochita za mankhwala oletsa kutupa omwe amapangidwa m'thupi lanu, monga tumor necrosis factor-alpha (TNF-alpha).
Kupsinjika maganizo ndi kutupa zimagwirizanitsidwa ndi matenda osiyanasiyana osatha, kuphatikizapo khansa, shuga, ndi matenda a mtima.
Chifukwa chake, anti-yotupa ndi antioxidant zotsatira za EGCG zimaganiziridwa kuti ndi chimodzi mwazifukwa zazikulu zogwiritsira ntchito poletsa matenda.
- Moyo wathanzi
Kafukufuku akuwonetsa kuti EGCG mu tiyi wobiriwira ikhoza kuthandizira thanzi la mtima mwa kuchepetsa kuthamanga kwa magazi, cholesterol, ndi kudzikundikira kwa zolengeza m'mitsempha - zonse zazikulu zomwe zimayambitsa matenda a mtima.
Mu kafukufuku wa masabata 8 mwa anthu 33, kutenga 250 mg wa EGCG wokhala ndi tiyi wobiriwira tsiku lililonse kunapangitsa kuti kuchepetsa kwambiri 4.5% ya LDL (yoyipa) cholesterol.
Kafukufuku wosiyana mwa anthu 56 adapeza kuchepa kwakukulu kwa kuthamanga kwa magazi, mafuta m'thupi, ndi zolembera zotupa mwa omwe amamwa 379 mg wa tiyi wobiriwira kwa miyezi itatu.
Ngakhale zotsatirazi ndi zolimbikitsa, kafukufuku wochuluka amafunika kumvetsetsa momwe EGCG mu tiyi wobiriwira ingachepetse chiopsezo cha matenda a mtima.
- Kuonda
EGCG imathanso kulimbikitsa kuchepa thupi, makamaka ikatengedwa limodzi ndi caffeine mwachilengedwe yomwe imapezeka mu tiyi wobiriwira.
Ngakhale kuti zotsatira zambiri za kafukufuku wa EGCG zimakhudza kulemera kwake ndizosagwirizana, kafukufuku wina wa nthawi yayitali adanena kuti kudya makapu awiri (14.7 ounces kapena 434 ml) a tiyi wobiriwira tsiku ndi tsiku kumagwirizana ndi kuchepa kwa thupi ndi kulemera kwake.
Kafukufuku wowonjezera wa anthu apeza kuti kutenga 100-460 mg wa EGCG pamodzi ndi 80-300 mg wa tiyi kapena khofi kwa milungu yosachepera 12 kumalumikizidwa ndi kuwonda komanso kuchepetsa mafuta m'thupi.
Komabe, kusintha kwa kulemera kapena kapangidwe ka thupi sikumawonedwa nthawi zonse pamene EGCG imatengedwa popanda caffeine.
- Ubongo wathanzi
Kafukufuku woyambirira akuwonetsa kuti EGCG ya tiyi wobiriwira imatha kuthandizira kukonza magwiridwe antchito amitsempha yama cell ndikupewa matenda osokonekera muubongo.
M'maphunziro ena, jakisoni wa EGCG adathandizira kwambiri kutupa, komanso kuchira komanso kusinthika kwa maselo a neural mu mbewa zovulala za msana.
Kuonjezera apo, kafukufuku wambiri wa anthu adapeza kugwirizana pakati pa kudya kwambiri kwa tiyi wobiriwira ndi kuchepetsa chiopsezo cha kuchepa kwa ubongo chifukwa cha ukalamba, komanso matenda a Alzheimer's and Parkinson. Komabe, zomwe zilipo ndizosagwirizana.
Kuonjezera apo, sizikudziwika ngati EGCG makamaka kapena zigawo zina za tiyi wobiriwira zimakhala ndi zotsatirazi.
Kafukufuku wochulukirapo akufunika kuti amvetsetse bwino ngati EGCG ingateteze kapena kuchiza matenda osokonekera muubongo mwa anthu.
