Nthawi yokolola ya tiyi yoyera ndikumayambiriro kasupe. Pogwiritsa ntchito, masamba ndi masamba ang'onoang'ono a zomera Camellia Sinensis, omwe ali ndi kukoma kokoma pang'ono, akuphatikizidwa. Chomera ichi chakhala chikulima kwa zaka zambiri ku China ndi India. Mankhwala ambiri a antioxidants omwe amapezeka ndi tiyi woyera amapezeka chifukwa cha mankhwala ochepa kwambiri. Ndiponsotu, mtundu uwu wamachiritso umapangitsa kuti kutayika kwa chinthu chamtengo wapatali chopezeka mu teyi - catechin. Masamba opangidwa bwino a Camellia Sinensis amagwiritsidwa ntchito popanga mitundu yakuda ndi yobiriwira.
Matayi a tiyi: caffeine ndi makatekini
Malangizo ndi zizindikiro zogwiritsira ntchito tiyi woyera polimbana ndi kulemera zimadalira kuti muli ndi tiyi ya cafein (poyerekeza ndi zobiriwira, zakuda kapena tiyi zofiira), komanso mosiyana, makatekini ambiri a polyphhenol omwe amathandiza kuwotcha mafuta, zomwe zimachititsa kuti thermogenesis ikhale yotentha. Ndizimene zimakhala ndi tiyi yoyera yomwe imalola olemba a "International Journal of Obesity" kutsimikizira zakumwa izi ngati gawo lofunika kwambiri pa kuchepetsa kulemera.
Ngati mukukhulupirira deta ya "Nutrition ndi Metabolism", methylxanthine, yomwe ili mbali ya tiyi yoyera, imathandizira kuwonongeka kwa mafuta ndikuwonjezera mphamvu yogwiritsira ntchito thupi. Ponena za polyphenols, gawo lalikulu limasewera ndi epigallocatechin-3-gallate. Izi zimathandizira kuchepetsa kukula kwa maselo atsopano a mafuta pogwiritsa ntchito triglycerides. Mawu ena, zinthu zomwe zimapanga teyi yoyera, zimachepetsa kwambiri mapangidwe ndi mapepala, zomwe zimawononga thupi.
Ntchito ya tiyi yoyera vdiete
Kuwongolera kwambiri zakudya ndiyeso lalikulu kwambiri, omwe angapo amatha kupirira. Zili pafupi kuchepetsa zakudya ndi momwe mungakulitsire chilakolako chanu. Chotsatira - zotsatira zonse za zakudya zidzapita ku "ayi." Chikho cha tiyi yoyera panthawi iliyonse ya chakudya chidzakuthandizani kuchepetsa njala ndi njala, kuchepetsa kukhumba kwa maswiti, ndi kuthandizira kufufuza kukula kwa zakudya zina. Mofananamo ndi tiyi woyera, tikulimbikitsidwa kugwiritsa ntchito zonunkhira ndi zokometsera, zomwe zimagwiritsidwa ntchito kuti zigwirizane ndi kulemera kwakukulu.
Mthandizi wamkulu yemwe ali ndi phindu lolemetsa
Mu 2009, "American Journal of Clinical Nutrition" inafalitsa nkhani yomwe inafotokozera zotsatira zabwino za kuyesera pogwiritsa ntchito tiyi woyera. Wolemba nkhaniyo, adokotala wa ku America KevinMaki, adanena kuti pali mgwirizano pakati pa makatekine ambiri ndi kulemera kwake.
Kuyesera kwa amuna omwe amadya zakudya zamakono ochepa amamwa tiyi wobiriwira ndi wakuda. Pamapeto pa masabata khumi, gulu lina la amuna omwe adamwa tiyi wobiriwira linataya mapaundi awiri owonjezera kuposa imodzi. Zakatekini zomwe zinali mu tiyi wobiriwira zinali 660 mg, ndipo zimakhala zakuda - 22 mg. Kuchuluka kwake kwa mlungu ndi mlungu kunali 0.25 makilogalamu.
Tiyi woyera ndi zothandiza zake
Katekisini omwe ali mu tiyi, amalimbikitsa kulimbikitsa chitetezo cha mthupi, kusokoneza kusintha kwa thupi ndi ukalamba. Mmodzi mwa akatswiri a Oncology Institute, ku Washington, DC, Demeter Whitmorch amawerenga kuti tiyi yoyera ya polyphenols imachepetsanso m'magazi, kuchepetsa magazi komanso kuteteza thupi la munthu ku khansa ya prostate.
Mu 2004, antchito a Manhattan University adanena kuti tiyi woyera ali ndi mankhwala oletsa tizilombo toyambitsa matenda komanso antibacterial.
Momwe mungayambitsire tiyi woyera molondola
Njira yopangira tiyi yoyera imafuna malamulo apadera. Mmodzi mwa iwo amaperekedwa kutentha kwa madzi, omwe ali odzazidwa ndi kutsekemera. Sitiyenera kupitirira 800 C. Ngati sizingatheke kutentha kutentha ndi thermometer, ndiye mutatha kuwiritsa umaloledwa kuti uzizizira pang'ono, ndipo izi ndi pafupi mphindi 5-10.
Chitetezo choyamba
Azimayi ayenera kukhala osamala kwambiri pakudya. Nkhumba yoyera ndi imodzi mwa zakumwa zotetezeka kwambiri, chifukwa chiwerengero chovomerezeka cha caffeine kwa amayi apakati si oposa 100 mg patsiku. Buku lina la British Medical Journal linanena kuti, ngati mankhwala a caffeine amatha kukhala aakulu kwambiri, amathandiza kuti mwanayo asatayike.
Zakumwa zomwe zimakhala zolimbikitsa zimatsutsana ndi anthu omwe ali ndi matenda, komanso matenda a impso. Zotsatira za caffeine zimatchulidwa mwansangamsanga, kuwonjezeka kwa nkhawa, kuwona bwino, mutu ndi mavuto a mtima.
Sikovomerezeka kusakaniza tiyi woyera ndi zakumwa zina ndikusiya kukoma kwake kokoma ndi fungo. Kuwonjezera apo, zidzataya katundu wake wambiri. Tiyenera kudziwa kuti tiyi, yomwe imagulitsidwa m'mabotolo apulasitiki, yataya makatekini ake 90% ndipo sikumwa mankhwala abwino.
