Abantu abaningi ngokwengeziwe bayazazi izinzuzo izitshalo namakhambi emvelo angasilethela zona. Yize umuthi wendabuko ungalokothi ushintshwe ngokuphelele, singasiza wona nathi uqobo. Ama-tea, isibonelo, aqukethe izakhi eziningi zezitshalo ezizuzisayo zomzimba wethu. Itiye eliluhlaza livelele ngaphezu kwakho konke ngenxa yemiphumela yalo yokwelapha ngenxa yamakatekini.
Awazi ukuthi ayini amakatekini? Lawa ama-antioxidants akhiqizwa izitshalo ezinikela ngezinzuzo eziningi zomzimba wethu. Uma ufuna ukwazi kabanzi ngalezi zinhlanganisela zemvelo, ngincoma ukuthi uqhubeke ufunda. Sizokhuluma ngalokho abayikho, imihlomulo yabo ngetiye eliluhlaza kanye nomphumela wabo kumdlavuza.
Ayini amakhethini?
I-antioxidant ye-polyphenolic ivela ezitshalweni, okungukuthi, uhlobo lwe-antioxidant olwakhiwe nge-polyphenols, ebizwa ngokuthi i-catechin. Ngaphakathi kwemifino, amakatekini avela njenge-metabolite yesibili. Zonke lezo zinhlanganisela ezikhiqizwa izitshalo, isikhunta noma amabhaktheriya abandakanyeka ngqo ekukhuleni kwazo, ekukhiqizweni noma ekukhuleni yi-metabolites eyinhloko, kanti eyesibili ayihlanganyeli ngqo kulezi zinqubo.
Igama elithi "catechin" livame ukusetshenziselwa ukubhekisa eqenjini elincane lama-falvan-3-ols noma ama-flavanols nasemndenini wama-flavonoids, onke angama-metabolites wesibili ezitshalo. Ngokuqondene negama, livela kujusi ekhishwe kufayela le- UCatechua mimosa, okungokomndeni ikatechu.
Amakhathiniki asetiyeni eliluhlaza
Kunezinto eziningi zezitshalo ezisetshenziswa kakhulu kuma-teas ngenxa yezinzuzo zazo eziningi nenani elikhulu lezakhamzimba. Ngokuqondile, itiye eliluhlaza linama-polyphenols amaningi imiphumela yawo ezuzisayo ihlukile. Lolu hlobo lokumnika imvamisa lunama-30% ala makhemikhali ngesisindo, phakathi kwayo kunenani eliphakeme lekhatheni elibizwa nge-EGCG noma i-epigallocatechin gallate.
Etiyeni eliluhlaza, lokhu kungenye yezinto ezibaluleke kakhulu nezifundwe ukuze welaphe izifo ezahlukahlukene. Ngalesi sizathu, lolu hlobo lokumnika lubhekwa njengezici zokwelapha. Ngaphezu kwalokho, itiye eliluhlaza liqukethe amanani amancane amaminerali abaluleke ngokulinganayo empilweni. Yize abanye abantu bekhetha ukuphuza itiye labo elihlanganiswe nobisi, lokhu kungahle kungabi umqondo omuhle kangako. Kunezifundo ezibonisa ukuthi ubisi lunganciphisa imiphumela yama-antioxidants njengamakhathekini.
Izinzuzo
AmaCatechin ahlinzeka ngezinzuzo ezahlukahlukene zomzimba wethu nempilo yethu. Ngalesi sizathu, kungakuhle ukuthi uphuze itiye eliluhlaza njalo. Phakathi kwezinzuzo eziningi ezinikezwa yi-antioxidants engokwemvelo, ukwehliswa kokwakhiwa kwama-radicals amahhala emzimbeni, ngaleyo ndlela kuvikelwe ama-molecule namaseli. Ama-radicals amahhala abandakanyeka kuzo zonke izinhlobo zezifo kanye neminyaka. Zisiza futhi ukulwa nomdlavuza futhi zinciphise ukuvuvukala.
AmaKhathekin vs. Umdlavuza
Lapho kunokukhula ngokweqile nokungalawulwa kwamaseli, kuvela isifo esesabekayo: umdlavuza. Namuhla ingenye yezimbangela ezihamba phambili zokufa emhlabeni wonke. Ngemuva kweminyaka eminingana yezifundo nocwaningo, kuyaziwa ukuthi umonakalo we-oxidative usiza ukuthuthukiswa kwalesi sifo. Ngakho-ke, Ama-antioxidants afana namakhatheni angaba nomphumela wokuvikela. Umthombo omuhle kakhulu wokudla lezi zinhlanganisela itiye eliluhlaza.
Kube nezifundo eziningana zokubuka nabantu abaphuze itiye eliluhlaza kanye nabanye abangaphuzanga. Lokhu kukhombisile lokho labo abadla lokhu kumnika kaningi akuvamile ukuthi bahlakulele izinhlobo ezithile zomdlavuza ezingaba zimbi kakhulu. Kodwa-ke, kudingeka izifundo eziningi kanye nocwaningo olwengeziwe ukuthola lokhu ngokunembile. Phakathi kwemiphumela etholakele kukhona okulandelayo:
- Umdlavuza webele: Kwenziwa ukuhlaziywa kwe-meta kokuhlola okwatholakala ukuthi abesifazane ababejwayele ukuphuza itiye eliluhlaza banciphisa amathuba okuthola umdlavuza webele phakathi kuka-20% no-30%. Kumele kuqashelwe ukuthi lolu hlobo lomdlavuza luvame kakhulu kubantu besifazane.
- Indlala yesinye: Emadodeni imiphumela yayiphezulu kakhulu. Ucwaningo luthole ukuthi labo abaphuza itiye eliluhlaza njalo bebengaphansi kwamaphesenti angama-48% ngekhulu yokuthola umdlavuza wesinye. Njengoba nje umdlavuza webele uvame kakhulu kwabesifazane, lokhu yikhona okuvame kakhulu emadodeni.
- Umdlavuza ocacile: Kukhona ukuhlaziywa okuhlanganisa ingqikithi yezifundo ezingama-29 ezihlobene netiye eluhlaza kanye nomdlavuza obala ngokwebala. Lokhu kukhombisa ukuthi abantu abaphuze lokhu kumnika yehlise ingozi yomdlavuza obala ngokwezibalo ngama-42%.
Yize izinzuzo zamakhatheni ziziningi, Akufanele siyeke ukuvakashela udokotela nokuthola ukuhlolwa njalo. Ukuthatha lawa ma-antioxidants ngetiye eliluhlaza, isibonelo, kungasisiza ukuvikela izinkinga, kepha ngeke ziselaphe noma zisigome.
