Ni gute icyayi cy'umukara Theabrownin bigira ingaruka ku rugero rwa cholesterol?

Igituntu ni ikintu kiboneka mu cyayi cy’umukara, cyane cyane mu cyayi cy’umukara gishaje cyangwa cyatetse. Ni cyo gituma iki cyayi kiba gifite ibara ryijimye n’uburyohe bwihariye. Ubushakashatsi ku byiza bishobora kubaho ku buzima bw’iki cyayi.Icyayi cy'umukara Theabrownin (TB)yagaragaje ingaruka zishimishije zayo ku rugero rwa cholesterol, bituma iba ikintu cy'ingenzi ku bashaka uburyo busanzwe bwo gushyigikira ubuzima bw'umutima.

Ubushakashatsi bwinshi bwakozwe ku ngaruka z'igituntu ku rugero rwa cholesterol. Ubushakashatsi bwasohotse mu kinyamakuru Journal of Agricultural and Food Chemistry mu 2017 bwagaragaje ko igituntu gikomoka ku cyayi cya Pu-erh, ubwoko bw'icyayi cy'umukara cyasembuye, cyagaragaje ingaruka zo kugabanya cholesterol mu bushakashatsi bwa laboratwari. Abashakashatsi babonye ko igituntu cyabujije ikorwa rya cholesterol mu turemangingo tw'umwijima, bigaragaza uburyo gishobora kugabanya cholesterol.

Ubundi bushakashatsi bwasohotse mu kinyamakuru Journal of Food Science mu 2019, bwakoze ubushakashatsi ku ngaruka z'ibice bikungahaye kuri TB bivuye mu cyayi cy'umukara ku mikorere ya cholesterol mu mbeba. Ibisubizo byagaragaje ko ibice bikungahaye kuri TB byashoboye kugabanya urugero rwa cholesterol ya LDL, ndetse bikongera urugero rwa cholesterol ya HDL, ikunze kwitwa cholesterol "nziza". Ibi byavumbuwe bigaragaza ko igituntu gishobora kugira ingaruka nziza ku buringanire bwa cholesterol mu mubiri, ari ingenzi ku buzima bw'umutima muri rusange.

Uburyo igituntu gishobora gukoresha mu kugabanya cholesterol buri mu byiciro byinshi. Uburyo bumwe butangwa ni ubushobozi bwacyo bwo kubuza cholesterol kwinjira mu mara, kimwe n'ibindi bintu bya polyphenolic biboneka mu cyayi. Mu kubangamira ubwikorezi bwa cholesterol mu mirire, igituntu gishobora kugira uruhare mu kugabanya urugero rwa cholesterol ya LDL mu maraso, bityo bikagabanya ibyago byo kurwara indwara z'umutima n'imitsi.

Uretse ingaruka zayo ku kwinjiza cholesterol, igituntu cyagaragaye ko gifite ubushobozi bwo kurwanya antioxydants. Imihangayiko ya oxidative izwiho kugira uruhare mu iterambere rya atherosclerosis, indwara irangwa no kwibumbira mu mitsi. Mu kugabanya imihangayiko ya oxidative, igituntu gishobora gufasha mu kurinda indwara ya atherosclerosis n'ingorane zijyana na yo, bigakomeza gushyigikira uruhare rwacyo mu guteza imbere ubuzima bw'umutima.

Ni ngombwa kumenya ko nubwo ubushakashatsi ku ngaruka za cholesterol ziterwa n'igituntu butanga icyizere, hakenewe ubundi bushakashatsi kugira ngo dusobanukirwe neza uburyo bukoreshwa no kumenya ingano nziza y'igituntu kugira ngo tugere kuri izi nyungu. Byongeye kandi, uburyo umuntu yitabira igituntu bushobora gutandukana, kandi izindi mpamvu nk'imirire, imibereho, n'imiterere y'uturemangingo na byo bishobora kugira ingaruka ku rugero rwa cholesterol.

Ku bantu bashishikajwe no gushyira igituntu mu bikorwa byabo bya buri munsi kugira ngo bakomeze ubuzima bw'umutima, hari amahitamo atandukanye ahari, harimo no kurya icyayi cy'umukara cyashaje cyangwa cyatetse, gisanzwe kirimo igituntu kinini. Byongeye kandi, guteza imbere icyayi cy'umukara gikungahaye kuri igituntu bitanga uburyo bworoshye bwo kurya ubwoko bwinshi bwa gituntu kugira ngo bugire akamaro ku buzima.

Kimwe mu bicuruzwa nk'ibi cyakunzwe cyane mu myaka ya vuba aha ni icyayi cy'umukara gikungahaye kuri TB. Ubu bwoko bw'icyayi cy'umukara cyiyongeraho ni ikintu gisanzwe gikoreshwa mu kugira ngo gishyiremo igituntu kinini, bityo kikaba gitanga uburyo bworoshye bwo gukoresha ikintu cy'ingirakamaro kiboneka mu cyayi cy'umukara. Gukoresha icyayi cy'umukara gikungahaye kuri TB bishobora gukurura cyane abashaka kongera ingaruka zishobora guterwa na cholesterol mu kugabanya igituntu.

Muri make, igituntu cy’igikatu, ikintu kidasanzwe kiboneka mu cyayi cy’umukara, kigaragaza icyizere mu bushobozi bwacyo bwo kugabanya urugero rwa cholesterol ya LDL no guteza imbere ubuzima bw’umutima. Nubwo hakenewe ubushakashatsi bwinshi kugira ngo dusobanukirwe neza uburyo kikoreshwa, ibimenyetso bihari bigaragaza ko igituntu gishobora kugira uruhare runini mu kunoza urugero rwa cholesterol. Ku bantu bashaka gushyigikira ubuzima bw’umutima wabo, gushyiramo ibikomoka ku cyayi cy’umukara gikungahaye kuri TB mu bikorwa byabo bya buri munsi bishobora kuba uburyo bworoshye kandi bushimishije bwo kubona ibyo byiza.
