Pali chinachake chomwe chimakhumudwitsa za kukwera chikho cha tiyi , ndipo mwina L-theanine. Amino amapezeka mwachibadwa mu tiyi wobiriwira, L-theanine amanenedwa kuti athetse nkhawa, kuchepetsa kugona, ndi kuchepetsa nkhawa.
Akugwiritsa ntchito L-Theanine
Otsutsa akuti L-theanine angathandize ndi matenda osiyanasiyana, monga nkhawa, kupanikizika, kuthamanga kwa magazi, cholesterol chokwanira, kusowa tulo, ndi nkhawa.
L-theanine amafunikanso kuonjezera ndondomeko, kupititsa patsogolo kulemera kwa thupi, komanso kulimbikitsa chitetezo cha mthupi. Kuonjezera apo, ena otsutsa amasonyeza kuti L-theanine akhoza kuteteza matenda a sitiroko, matenda a Alzheimer, ndi mitundu ina ya khansa.
Ubwino wa L-Theanine
Mpaka lero, asayansi sanayambe kufufuza kwambiri za ubwino wa L-theanine. Komabe, kufufuza koyambirira kumasonyeza kuti kungathandizire kukweza maganizo, kupititsa patsogolo ubongo kugwira ntchito, ndi kuchepetsa momwe thupi limayankhira kupsinjika ndi nkhawa. Pano pali kuyang'ana pa zofufuza zina zazikulu:
1) Nkhawa
Malinga ndi kafukufuku wa 2016, L-theanine ingathandize kuchepetsa nkhawa. Ophunzira omwe ali ndi thanzi labwino adamwa zakumwa zomwe zili ndi 200 mg L-theanine kapena placebo. Ola limodzi mutatha kumwa, vuto lakumvera kukumvetsa kwadzidzidzi kunachepetsedwa kwambiri mwa iwo omwe adya kumwa L-theanine. Patangotha maola atatu, mphuno ya cortisol (mahomoni obisika chifukwa cha nkhawa) inali yochepa kwambiri.
Kafukufuku wina adafufuzanso kuti L-theanine amayamba kugwiritsa ntchito nthawi zonse ndikupeza kuti kudya kwa tsiku ndi tsiku kunachepetsanso kupanikizika ndi mitsempha ya α-amylase (enzyme yomwe imatulutsidwa chifukwa cha nkhawa) m'maphunziro apamwamba omwe akukumana ndi mavuto.
2) Kugona
Kufufuza koyamba kunayang'ana zotsatira za tiyi ya tiyi yobiriwira pa ubwino wa tulo (caffeine mu tiyi wobiriwira ikhoza kusokoneza kugona ndipo ingayesetse zotsatira za theanine).
Atatha kumwa tiyi wobiriwira tsiku ndi tsiku kwa masiku asanu ndi awiri, timagulu ta alpha-amylase timakhala otsika kwambiri mwa iwo omwe ankamwa tiyi yobiriwira kwambiri kusiyana ndi omwe ankadya tiyi yobiriwira. Mbali ya kugona inali yowonjezereka kwa iwo amene adadya tepi yobiriwira yobiriwira.
3) Kuvutika maganizo
Phunziro la 2017 lomwe linafalitsidwa mu Acta Neuropsychiatrica linagwiritsa ntchito L-theanine chifukwa cha kupsinjika kwakukulu. Mlanduwu unaphatikizapo amuna ndi akazi 20 omwe anali ndi 250 mg a L-theanine omwe anawonjezera mankhwala awo kwa milungu eyiti. Iwo anapeza kuti anali ndi phindu lothandizira kuthetsa nkhaŵa, kusokonezeka tulo, ndi kukhumudwa kwa chidziwitso chokhudzana ndi kuvutika maganizo.
4) Ntchito Yoganizira
Kafukufuku wa 2010 kuchokera ku Nutrition Neuroscience akuwonetsa kuti kuphatikiza L-theanine ndi caffeine kungathandize kuthetsa kulingalira ntchito.
Phunziroli, anyamata 44 adatenga placebo kapena kuphatikiza L-theanine ndi caffeine musanachite ntchito yodziwa zambiri. Ochita kafukufuku anapeza kuti kuphatikiza L-theanine ndi caffeine kunasintha kwambiri molondola komanso mosamala. Zithandizanso kuwonjezera chidwi pakuchita ntchitoyi.
5) Kutaya Kwambiri
L-theanine amasonyeza lonjezano ngati thandizo lolemetsa, malinga ndi kafukufuku woyambirira wa nyama wofalitsidwa m'nyuzipepala ya In Vivo .
Pa kuyesera kwa ntchentche kudyetsa ufa wa tiyi wobiriwira, ofufuza adapeza kuti L-theanine ndi caffeine yomwe imapezeka mu ufawu imayesedwa kuti iteteze kulemera ndi kumenyana ndi mafuta.
Zotsatira Zotsatira
Pakadali pano, sadziwa pang'ono za chitetezo chogwiritsa ntchito L-theanine zowonjezereka m'nthawi yayitali. L-theanine nthawi zambiri imakhala yotetezeka ikagwiritsidwa ntchito mu tiyi wobiriwira, komabe National Institutes of Health amachenjeza kuti asamamwe makapu asanu a tiyi tsiku lililonse.
Chifukwa chakudya cha khofi, kumwa mowa kwambiri tiyi kungayambitsenso zotsatira zina. Izi zingaphatikizepo kupweteka mutu, kusowa tulo, kukwiya, kutsekula m'mimba, ndi kupweteka kwa mtima.
Palinso ndi nkhawa kuti kutenga L-theanine kuphatikizapo mankhwala osokoneza bongo, mankhwala ochepetsa kumwa mankhwala, komanso / kapena mankhwala osokoneza bongo amachititsa zotsatira zovulaza.
Zakudya zowonjezera zakudya sizinayesedwe kuti zisawonongeke. Chifukwa chakuti iwo sagwirizana ndi malamulo, zomwe zili m'magulu ena zimasiyana ndi zomwe zafotokozedwa palemba la mankhwala.
Komanso, kumbukirani kuti chitetezo cha mankhwala opatsirana mwa amayi apakati, amayi oyamwitsa, ana, ndi omwe ali ndi matenda kapena omwe akumwa mankhwala sakhazikitsidwe.
Kumene Mungapeze L-Theanine
Zowonjezeka kuti zithe kugula pa intaneti, L-theanine zowonjezereka zimagulitsidwa m'masitolo ambiri achilengedwe ndi m'masitolo ogwirizana ndi zakudya zowonjezera zakudya.
L-theanine imapezedwanso mu tiyi wobiriwira. Ngakhale zili zosiyana, kapu ya tiyi ili pafupi 25 mg wa L-theanine.
Mfundo Yofunika Kwambiri
Pamene kuwonjezereka kwanu kwa L-theanine podya tiyi wobiriwira nthawi zonse kungakuthandizeni kuti mukhale ndi thanzi labwino, posakhalitsa kuti mutenge mankhwala a L-theanine kuti mukhale ndi thanzi labwino.
Ngati mukuganiza zogwiritsira ntchito mankhwala a L-theanine, lankhulani ndi dokotala poyamba. Kudzisamalira komanso kupewa kapena kuchepetsa kusamalidwa kosatha kungakhale ndi zotsatira zoopsa.
