Reka ntangire mvuga ko icyayi kibisi ari ikintu cyiza.
Icyayi kibisi kirimo ibintu bitandukanye bikora, icy'ingenzi muri byo ni icyayi cya polifenole (mu magambo ahinnye yitwa GTP), uruganda rw’imiti myinshi ya hydroxyphenolique mu cyayi kibisi, igizwe n’ibintu birenga 30 bya fenolike, ibyingenzi ni catechine n'ibiyikomokaho. .Icyayi cya polifenole gifite antioxydants, irwanya imirasire, irwanya gusaza, hypolipidemic, hypoglycemic, anti-bacterial na enzyme ibuza ibikorwa bya physiologique.
Kubera iyo mpamvu, icyayi kibisi gikoreshwa cyane mubuvuzi, ibiryo, ibicuruzwa byo murugo ndetse hafi ya hose, bizana inyungu nyinshi mubuzima bwabantu nubuzima.Icyakora, icyayi kibisi, ibintu bishakishwa cyane byagenze neza, cyasutswe gitunguranye n’umuryango w’ubumwe bw’ibihugu by’Uburayi, kivuga ko EGCG, ingenzi cyane mu cyayi kibisi, ari hepatotoxic kandi ishobora kwangiza umwijima iyo uyikoresheje birenze.
Abantu benshi bamaze igihe kinini banywa icyayi kibisi ntibazi neza kandi bafite ubwoba niba bagomba gukomeza kubinywa cyangwa kubireka.Hariho kandi abantu bamwe banze ibyo EU ivuga, bemeza ko abo banyamahanga bahuze cyane, bagavamo umunuko unuka buri kanya.
By'umwihariko, ingaruka z’ingaruka zatewe n’amabwiriza mashya ya Komisiyo (EU) 2022/2340 yo ku ya 30 Ugushyingo 022, ahindura Umugereka wa III w’Amabwiriza (EC) No 1925/2006 y’Inteko Ishinga Amategeko y’Uburayi ndetse n’Inama Njyanama ashyiramo ibikomoka ku cyayi kibisi birimo EGCG murutonde rwibintu byabujijwe.
Amabwiriza mashya asanzwe akurikizwa arasaba ko ibicuruzwa byose bireba bitubahirije amabwiriza bizabuzwa kugurishwa guhera ku ya 21 Kamena 2023.
Iri ni ryo tegeko ryambere kwisi kugabanya ibintu bikora mubicuruzwa byicyayi kibisi.Abantu bamwe bashobora gutekereza ko icyayi kibisi cyigihugu cyacu cya kera gifite amateka maremare, bitwaye iki EU?Mubyukuri, iki gitekerezo ni gito cyane, muri iki gihe isoko ryisi rifite umubiri wose urimo, iri tegeko rishya rwose rizagira ingaruka cyane mugihe kizaza cyoherezwa mu mahanga ibicuruzwa byicyayi kibisi mubushinwa, ariko kandi ninganda nyinshi kugirango zongere gushyiraho ibipimo ngenderwaho.
None, uku kubuzwa kutuburira ko natwe tugomba kwitondera kunywa icyayi kibisi mugihe kizaza, kuko ibyinshi bishobora kwangiza ubuzima bwacu?Reka dusesengure.
Icyayi kibisi gikungahaye ku cyayi polifenol, iki kintu gikora gifite 20-30% byuburemere bwumye bwamababi yicyayi, kandi ibyingenzi byingenzi bigize imiti imbere yicyayi polifenole bigabanijwemo ibyiciro bine byibintu nka catechine, flavonoide, anthocyanine, fenolike acide, nibindi, byumwihariko, ibirimo byinshi bya catechine, bingana na 60-80% byicyayi polifenol.
Muri catechine, harimo ibintu bine: epigallocatechin, epigallocatechin, epigallocatechin gallate na epigallocatechin gallate, muri yo galit ya epigallocatechin niyo ifite EGCG nyinshi, bingana na 50-80% bya catechine yose, kandi ni iyi EGCG Bikora cyane.
Muri rusange, igice cyingenzi cyicyayi kibisi kubuzima bwabantu ni EGCG, ibintu bikora bingana na 6 kugeza kuri 20% byuburemere bwumye bwamababi yicyayi.Amabwiriza mashya y’ubumwe bw’ibihugu by’Uburayi (EU) 2022/2340 nayo agabanya EGCG, isaba ibikomoka ku cyayi byose kuba bitarenze 800mg bya EGCG ku munsi.
Ibi bivuze ko ibicuruzwa byose byicyayi bigomba kugira buri munsi gufata munsi ya 800 mg ya EGCG kumuntu kubunini bwa serivisi bwerekanwe mumabwiriza.
Uyu mwanzuro wagezeho kubera ko mu 2015, Noruveje, Suwede na Danemark byari bimaze gusaba Umuryango w’ubumwe bw’ibihugu by’Uburayi ko EGCG yashyirwa ku rutonde rw’imikoreshereze yabujijwe ku bijyanye n'ingaruka zishobora guterwa no kuribwa kwayo.Hashingiwe kuri ibyo, Umuryango w’ubumwe bw’ibihugu by’Uburayi wasabye Ikigo cy’Uburayi gishinzwe umutekano mu biribwa (EFSA) gukora isuzuma ry’umutekano kuri catechine yicyayi kibisi.
EFSA yasuzumye mu bizamini bitandukanye ko EGCG mu mubare urenze cyangwa uhwanye na mg 800 ku munsi bishobora gutera kwiyongera kwa serumu transaminase no kwangiza umwijima.Kubera iyo mpamvu, amabwiriza mashya y’ubumwe bw’ibihugu by’Uburayi ashyiraho mg 800 nk’umupaka wa EGCG mu bicuruzwa by’icyayi.
Noneho dukwiye guhagarika kunywa icyayi kibisi mugihe kizaza, cyangwa twirinde kutanywa inzoga nyinshi burimunsi?
Mubyukuri, tuzashobora kubona ingaruka zibi bibuza kunywa icyayi kibisi dukora ibarwa bisanzwe.Ukurikije kubara ko EGCG ifite hafi 10% yuburemere bwumye bwamababi yicyayi, tael 1 yicyayi irimo garama 5 za EGCG, cyangwa 5000 mg.Iyi mibare isa naho iteye ubwoba, kandi kuri 800 mg ntarengwa, EGCG muri tael 1 yicyayi irashobora kwangiza umwijima kubantu 6.
Nyamara, ikigaragara ni uko EGCG iri mu cyayi kibisi itandukana cyane bitewe nuburyo bwubwoko bwicyayi nuburyo bwo kuyibyaza umusaruro, kandi izo nzego zose zikururwa murwego, zose ntizishonga mu cyayi kandi, bitewe nubushyuhe y'amazi, irashobora gutuma EGCG itakaza ibikorwa byayo.
Kubwibyo, Umuryango w’ubumwe bw’ibihugu by’Uburayi n’ubushakashatsi butandukanye ntabwo utanga amakuru yerekana uko icyayi gifite umutekano ku bantu banywa buri munsi.Abantu bamwe barabaze, bashingiye ku makuru afatika yatangajwe n’ubumwe bw’ibihugu by’Uburayi, ko kugira ngo banywa mg 800 za EGCG, bakeneye kurya b 50 kugeza ku 100 by’amababi y’icyayi yumye burundu, cyangwa bakanywa hafi miriyoni 34.000 z’icyayi kibisi.
Niba umuntu afite akamenyero ko guhekenya tael 1 yicyayi yumye buri munsi cyangwa kunywa miriyoni 34.000 zicyayi cyokeje cyicyayi buri munsi, igihe kirageze cyo gusuzuma umwijima kandi birashoboka ko byatewe numwijima.Ariko birasa nkaho abantu bake cyane cyangwa badahari, kubwibyo rero nta kibi kiri mu bantu bakomeza kugira akamenyero ko kunywa icyayi kibisi buri munsi, hari inyungu nyinshi.
Ikintu cyingenzi kumenya hano nuko abantu bafite icyifuzo cyo guhekenya icyayi cyumye cyangwa kunywa icyayi gikomeye cyane umunsi wose bagomba gushyira mu gaciro.Icy'ingenzi birumvikana ko abantu bafite akamenyero ko gufata inyongeramusaruro zirimo icyayi kibisi nka catechine cyangwa EGCG bagomba gusoma ikirango neza kugirango barebe niba bazarenga mg 800 za EGCG kumunsi kugirango babashe kwirinda ingaruka .
Muri make, amabwiriza mashya y’ubumwe bw’ibihugu by’Uburayi agenewe cyane cyane ibikomoka ku cyayi kibisi kandi bizagira ingaruka nke ku ngeso zacu zo kunywa buri munsi.
