Iti emnyama ibisoloko ithandwa ngenxa yencasa yayo etyebileyo kunye neenzuzo zayo zempilo. Enye yezona zinto ziphambili zeti emnyama eziye zatsala ingqalelo kwiminyaka yakutshanje yi-theabrownin, into ekhethekileyo eye yafundwa ngemiphumo yayo enokubakho kumanqanaba e-cholesterol. Kweli nqaku, siza kuphonononga ulwalamano phakathi kweti emnyama.i-theabrowninkunye namanqanaba e-cholesterol, kugxilwe ekukhuthazeni iingenelo ezinokubakho zeemveliso ze-theabrownin kwimpilo yentliziyo.
I-TB yikhompawundi ye-polyphenolic efumaneka kwiti emnyama, ngakumbi kwiti ezimnyama ezindala okanye ezivundisiweyo. Inoxanduva lombala omnyama kunye nencasa eyahlukileyo yezi ti. Phanda ngeenzuzo zempilo ezinokubakhoIti emnyama iTheabrownin (TB)ityhile iziphumo zayo ezinomdla kumanqanaba e-cholesterol, nto leyo eyenza ukuba ibe yindawo enomdla kwabo bafuna iindlela zendalo zokuxhasa impilo yentliziyo.
Izifundo ezininzi ziphande ngemiphumo yeTB kumanqanaba echolesterol. Uphononongo olupapashwe kwiJournal of Agricultural and Food Chemistry ngo-2017 lufumanise ukuba iTB ekhutshwe kwiPu-erh tea, uhlobo lweti emnyama ebilisiwe, ibonise iziphumo zokunciphisa icholesterol kwiimvavanyo zelebhu. Abaphandi baqaphele ukuba iTB ithintele ukwenziwa kwecholesterol kwiiseli zesibindi, nto leyo ebonisa indlela enokwenzeka yokunciphisa icholesterol.
Olunye uphando, olupapashwe kwiJournal of Food Science ngo-2019, luphande ngemiphumo yeenxalenye ezityebileyo zeTB ezivela kwiti emnyama kwimetabolism yecholesterol kwiimpuku. Iziphumo zibonise ukuba iinxalenye ezityebileyo zeTB zikwazile ukunciphisa amanqanaba e-LDL cholesterol, ngelixa zikwanyusa amanqanaba e-HDL cholesterol, edla ngokubizwa ngokuba yi-cholesterol "elungileyo". Ezi ziphumo zibonisa ukuba i-TB inokuba nefuthe elihle kumlinganiselo we-cholesterol emzimbeni, nto leyo ibalulekileyo kwimpilo yentliziyo iyonke.
Iindlela ezinokwenzeka apho i-TB inokusebenzisa khona imiphumo yayo yokunciphisa i-cholesterol zininzi. Enye indlela ecetywayo kukukwazi kwayo ukuthintela ukufunxwa kwe-cholesterol emathunjini, efana nezinye iikhompawundi ze-polyphenolic ezifumaneka kwiti. Ngokuphazamisa ukuthuthwa kwe-cholesterol yokutya, i-TB inokuba negalelo ekunciphiseni amanqanaba e-LDL cholesterol egazini, ngaloo ndlela inciphisa umngcipheko wesifo sentliziyo.
Ukongeza kwimiphumo yayo ekufunxeni i-cholesterol, i-TB ikwabonakalisiwe ukuba ineempawu ze-antioxidant. Uxinzelelo lwe-oxidative luyaziwa ukuba lunegalelo ekuphuhlisweni kwe-atherosclerosis, imeko ebonakaliswa kukwakheka kwe-plaque kwimithambo yegazi. Ngokunciphisa uxinzelelo lwe-oxidative, i-TB inokunceda ekukhuseleni ekuphuhlisweni kwe-atherosclerosis kunye neengxaki ezinxulumene nayo, ixhasa ngakumbi indima yayo enokubakho ekukhuthazeni impilo yentliziyo.
Kubalulekile ukuqaphela ukuba nangona uphando malunga nemiphumo yokunciphisa i-cholesterol ye-TB luthembisa, kufuneka uphando oluthe kratya ukuze kuqondwe ngokupheleleyo iindlela ezibandakanyekayo kunye nokuchonga ubungakanani obufanelekileyo bokusetyenziswa kwe-TB ukuze kufezekiswe ezi nzuzo. Ukongeza, iimpendulo zomntu ngamnye kwi-TB zinokwahluka, kwaye ezinye izinto ezifana nokutya, indlela yokuphila, kunye nemfuza nazo zinokuchaphazela amanqanaba e-cholesterol.
Kwabo banomdla wokufaka i-TB kwimisebenzi yabo yemihla ngemihla ukuze baxhase impilo yentliziyo, kukho iindlela ezahlukeneyo ezikhoyo, kubandakanya ukusetyenziswa kweti ezimnyama ezindala okanye ezibilisiweyo, eziqulethe amanqanaba aphezulu e-TB. Ukongeza, ukuphuhliswa kweemveliso zeti ezimnyama ezityebiswe yi-TB kunika indlela elula yokutya iintlobo ezixineneyo ze-TB ukuze ufumane iingenelo zempilo.
Enye imveliso enjalo efumene ingqalelo kwiminyaka yakutshanje yi-black tea extract etyebiswe yiTB. Olu hlobo lwe-black tea extract oluxineneyo lulungelelaniswe ukuba luqulathe amanqanaba aphezulu eTB, nto leyo enika indlela elula yokusebenzisa i-compound eluncedo efumaneka kwi-black tea. Ukusetyenziswa kweemveliso ze-black tea etyebiswe yiTB kunokuba nomtsalane ngakumbi kwabo bafuna ukwandisa iziphumo ze-cholesterol ezinokubakho zeTB.
Ukuqukumbela, iTB, into eyahlukileyo efumaneka kwiti emnyama, ibonisa ithemba kumandla ayo okunciphisa amanqanaba e-cholesterol ye-LDL nokukhuthaza impilo yentliziyo. Nangona kufuneka uphando oluthe kratya ukuqonda ngokupheleleyo iindlela ezibandakanyekayo, ubungqina obukhoyo bubonisa ukuba iTB inokudlala indima eluncedo ekuphuculeni amanqanaba e-cholesterol. Kubantu abafuna ukuxhasa impilo yentliziyo yabo, ukufaka iimveliso zeti emnyama etyebileyo kwi-TB kwimisebenzi yabo yemihla ngemihla kunokuba yindlela elula neyonwabisayo yokufumana ezi zibonelelo.
