Ikofi kunye neyeyi akuzona ukutya okuyisiseko ezifunekayo ngumzimba wesifazana, kodwa iifotyi zekhofi kunye namaqabunga etiye zifumaneka malunga nentsapho nganye. Zomibini zezi ziphulo zizonandi kakhulu, zinefuthe. Ngaloo ndlela, ikhofi kunye neyeyi kunye nemilinganiselo echanekileyo iyiluncedo, kodwa xa bexhatshazwa umphumo wabo kwimpilo yowesifazane ingaba nefuthe elibi.
Ikhofi kunye nehayi zisebenza njani ?
Ikhofi yomhlaba kunye namaqabunga etiya athululelwa ngamanzi abilayo, apho ngaphandle kweminye imimandla, i-alkaloids, i-nitrogen equkethe i-organic compounds, ichithwa, iindleko ezinkulu ezinokuthi zityhefu. I-Alkaloids isenzo kwintliziyo kunye nomgogodla. Ikhofi kunye netiyi ziqukethe i-caffeine alkaloid. Ngaphambili kwakucatshulwa ukuba itiye iqukethe i-alkaloid ethile yewayini, kodwa izazinzulu kwiminyaka yamuva zizimisele ukuba oku akunjalo. Ikhofi iqulethe i-1.2 - 1.4% i-caffeine, ngelixa ikhofi ye-decafeinine, ininzi i-0.1%. Etiyi, i-cafeine (ngaphezulu kwe-5%). Nangona kunjalo, i-cafeine ye-tea iyafuneka i-tannin, ngoko i-cafeine ye-tea esuka kwindlela yokugaya ihamba ngokukhawuleza. Ngenxa yoko, ukuvuselela kunye nokukhipha itiye kuqala ukusebenza emva kwekhofi, kodwa igalelo layo lihle kakhulu. Ikhofiyini yekhofiyini ibinomphumo oshukumisayo kwinkqubo ye-cardiovascular system, kunye ne-tea caffeine-kwingqondo kunye nenkqubo yesantya yabasetyhini.
Ingaba ikhofi ne teyi yingozi?
Isixa esikhulu se-caffeine sinetyhefu, kwaye i-dose ebulalayo iigrimu ezilishumi (ezihambelana neekhepti ezilikhulu zekhofi zonywa enye enye). Emzimbeni womfazi, i-caffeine ayifuni, isiqingatha se-caffeine eshiyiweyo ikwahlula kwiiyure ezingama-3-5, kwaye emva kweeyure ezingama-24, inani elincinci kuphela lihlala emzimbeni. Ngokutsho kwedatha yakutsha yophando, i-caffeine ayinakuthintelo ekuphuhlisweni kwesifo senhliziyo (ezintandathu iikomityi zekhofi ngosuku) okanye ezinye iingxaki zempilo, ezifana nesifo sikashukela, i-cirrhosis, isifo somhlaza nesifo somhlaza. I-Gout okanye isilonda sesisu asisona sizathu sokusetyenziswa kakubi kwekhofi okanye itiye, kodwa sisiphumo sokungondleki, ukutshaya nokusetyenziswa kakubi kotywala.
Ngamanye amaxesha isisu sithukuthele
I-cafeine kunye nama-tannins yekhofi kunye netiyi kukhuthaza ukukhutshwa kwe-mucosa yesisu. Ngoko ke, kubantu abanobuhlungu emva kokuba ikhofi iqala ukuvula isisu. Ukuba awufuni ukuyeka inkomishi yekhofi yasekuseni, uze uyiphuze ngaphandle kwe-caffeine. Unempembelelo embi kwisisu.
Ukuphuza okufutshane okufutshane
Ikhofi-bonisa ukuba isisu sinomsebenzi ngakumbi kunokuba siqhele, njengoko ikhofi idluliselwa kwifayile. Xa ukwenza ikhofi ibonakalise kwisixhobo esikhethekileyo ngekhofi yomhlaba, umphunga wamanzi phantsi kwengcinezelo udlula ngaphantsi kwengcinezelo emininzi imizuzwana, kwaye i-tannins kunye nentlungu ayinaso ixesha lokuchithwa. Ngalo mgaqo, itiye iphepheni kwaye ikhuphe isisu. Ukuphuza i-tea ayifuni ngaphezu kwemizuzu emithathu, kuba ngelo xesha i-caffinine iyaqhaqhazela, kodwa ayikho i-tanins. Kwaye ukuba i-tea ingabonakali yomelele, ngoko kuyimfuneko ukuthatha inani elikhulu lamaqabunga eti kunye nokuthulula amanzi abilayo ixesha elifutshane.
Ikhofi neyeyi ngexesha lokukhulelwa
Ubushushu be-fetus buqhekeza i-caffeine (ifumane negazi lomama) ngokuthe tye ngaphezu kwesibindi somntu omdala. Ngethuba langoku alisayi kucacisa ukuba le nto inonakalisa umntwana ozayo. Nangona kunjalo, kubonakaliswe, ukuba umama ozayo usebenzisa kakubi ikhofi okanye itiye (iziphuzo ezingaphezu kweebhozo ezisibhozo ngosuku), ngoko ke amathuba okuba umntwana angabikho komntwana.
