Kule nkathi esheshayo nenengcindezi ephezulu, impilo isibe yingcebo yethu eyigugu kakhulu. Ngokuthuthuka kwezobuchwepheshe kanye nokujula kocwaningo lokudla okunempilo, abantu baya ngokuya beqaphela ukuthi ngaphezu kokudla okunomsoco nokuzivocavoca umzimba okusesilinganisweni, ama-antioxidants adlala indima ebalulekile ekugcineni impilo yomzimba kanye nokumelana nokulimala kwama-radical wamahhala. Namuhla, ake singene ohambweni lokuhlola ndawonye ukuze sifunde ngenqubo ephindaphindwayo yama-antioxidant kusukela kuziphiwo zakudala zemvelo kuya ekuhlanganiseni kwesayensi yesimanje, kanye nokuthi baye baba kanjani ozakwethu ababalulekile ekunakekelweni kwethu kwezempilo kwansuku zonke.
1, Isingeniso sama-Antioxidants: Isipho esivela Emvelweni
Ama-Antioxidants, ngamagama alula, awuhlobo lwento engavimbela noma ibambezele inqubo ye-oxidation. I-oxidation itholakala yonke indawo ekuphileni kwethu kwansuku zonke, kusukela ezinzipho zensimbi ezigqwalile kuya ekuwohlokeni kokudla, konke okuwumphumela we-oxidation. Emzimbeni womuntu, ukusabela kwe-oxidation nakho kubalulekile njengoba kuyisisekelo sokukhiqiza amandla. Kodwa-ke, lapho lokhu kusabela kungalawuleki futhi kukhiqiza ama-radicals mahhala amaningi kakhulu, kuzolimaza ukwakheka kwamangqamuzana, i-DNA ngisho nomzimba wonke, kusheshise inqubo yokuguga, futhi kubangele izifo ezihlukahlukene, njengesifo senhliziyo, umdlavuza kanye isifo sikashukela.
Ukuhlakanipha kwemvelo kulele eqinisweni lokuthi kakade isilungiselele umthombo ocebile wama-antioxidants kithi. Ezikhathini zasendulo, abantu bathola ukudla okuningi kwemvelo okunemiphumela yokulwa ne-antioxidant ngokubuka nangokuprakthiza, njengezithelo ezisawolintshi ezinovithamini C, izaqathi ezicebile nge-beta carotene, namajikijolo aluhlaza anothe ngama-anthocyanins. Izingxenye ze-antioxidant kulokhu kudla zinganciphisa ama-radicals mahhala emzimbeni, zivikele amangqamuzana emonakalweni, futhi zibe isikhali semvelo sabantu sokumelana nezifo nokugcina ubungqabavu bobusha.
2, Ukuhlola Kwesayensi: Ukweqa Usuka Ekudleni Kuya Ezingcaphuno
Ngokukhula kwe-biochemistry nokudla, ososayensi sebeqalile ukuhlolisisa ukwakheka, indlela yokusebenza, kanye nokutholakala kwe-bioavailability yalezi zici zemvelo ze-antioxidant. Maphakathi nekhulu lama-20, ngokuthuthuka kobuchwepheshe bokuhlukanisa nokuhlanza, abantu bakhipha ngempumelelo ama-antioxidants ahlukahlukene ezitshalweni, izithelo, nokusanhlamvu, okufana novithamini E, uvithamini C, i-selenium, i-carotenoids, nama-polyphenols ezitshalo ahlukahlukene, bawethula imakethe ngendlela yezithako, ehlinzeka ngezinketho ezintsha zalabo abangakwazi ukuhlangabezana nezidingo zabo ze-antioxidant ngokudla kwansuku zonke.
Ngalesi sikhathi, ukusetshenziswa kwama-antioxidants kwakungasagcini ekwelapheni okungokwesiko kokudla, kodwa kwangena emkhakheni wokuphathwa kwezempilo okucwengisiswe kakhudlwana nokuvimbela izifo. Ososayensi baqinisekise imiphumela emihle yama-antioxidant athile ekwehliseni ubungozi besifo senhliziyo, ukuthuthukisa ukusebenza kwamasosha omzimba, kanye nokubambezeleka kokuguga kwesikhumba ngokuhlolwa kwemitholampilo, kuqhubeke nokuthuthukisa ukuchuma kwemakethe ye-antioxidant.
3, Ukufika kwenkathi yokwenziwa: izixazululo ezinembile nezisebenzayo ze-antioxidant
Nakuba ama-antioxidants emvelo anezinzuzo eziningi, ukuzinza kwawo, i-bioavailability, kanye nemikhawulo yomsebenzi ngaphansi kwezimo ezithile ezithile kuye kwashukumisela ososayensi ukuba bahlole izindlela ezintsha - ama-antioxidant okwenziwa. Ama-antioxidants okwenziwa, okuyizinto zokulwa ne-antioxidant ezenziwe ngokuzenzisa ngezindlela zamakhemikhali, ahlose ukunqoba imikhawulo ethile yama-antioxidants emvelo futhi anikeze isivikelo esine-antioxidant esinembe kakhudlwana, esisebenza kahle futhi esizinzile.
Phakathi kwazo, ama-antioxidant amele kakhulu okwenziwa afaka i-butyl hydroxyanisole (BHA), i-dibutyl hydroxytoluene (BHT), futhi muva nje uthole ukunakwa okufana ne-lipoic acid. Lawa makhompiyutha aklanywe ngokucophelela ukuze asuse ngokuphumelelayo ama-radicals mahhala, kuyilapho egcina ukuzinza okuhle nempilo yeshelufu ende, okuwenza afanelekele ukucubungula ukudla okuhlukahlukene, ukukhiqizwa kwemithi, nokuthuthukiswa kwemikhiqizo yezempilo.
Kuyaqapheleka ukuthi ukusetshenziswa kwama-antioxidant okwenziwa angaphandle kokuphikisana. Ukuhlolwa kokuphepha, ukulawulwa komthamo, kanye nocwaningo lomthelela wesikhathi eside bekulokhu kugxilwe kakhulu ekunakeni kososayensi. Ukuqinisekisa ukuthi ama-antioxidants okwenziwa ahlinzeka ngezinzuzo zezempilo ngaphandle kokubangela imiphumela emibi emzimbeni womuntu kuyinto ehamba phambili ocwaningweni lwesayensi.
4, Amathemba esikhathi esizayo: Amasu e-antioxidant enziwe ngezifiso
Ngokuthuthuka okusheshayo kwe-genomics, i-metabolomics, ne-bioinformatics, singena enkathini yokwelashwa okunembayo. Ucwaningo lwesikhathi esizayo lwe-antioxidant nentuthuko luzonaka kakhulu umehluko ngamunye, futhi lulungise izinhlelo ze-antioxidant zomuntu ngamunye ngokuhlolwa kofuzo, ukuhlaziywa kwe-metabolic, nezinye izindlela. Lokhu kusho ukuthi ama-antioxidants esikhathi esizayo angase angabi nje izithako ezilula zomsoco, kodwa amasu okungenelela aphelele asekelwe olwazini oluningi olufana nesizinda sofuzo lomuntu siqu, imikhuba yokuphila, kanye nesimo sezempilo.
Ngaphezu kwalokho, ukuhlanganiswa kwe-nanotechnology kanye ne-biotechnology kuzoletha izinguquko ezishintshayo ekuthuthukisweni kwama-antioxidants. Ngobuchwepheshe be-nanocarrier, ama-antioxidants angangena ngempumelelo kulwelwesi lwamaseli futhi afinyelele izicubu ezihlosiwe; I-Biotechnology ingase idale ama-molecule amasha e-antioxidant anomsebenzi ophezulu kanye nokucacisa, ivule isahluko esisha ekusetshenzisweni kwama-antioxidants.
