Ama-radicals wamahhala angama-molecule engaqiniseki angalimaza amangqamuzana emzimbeni wakho. Bakha lapho ama-athomu noma ama-molecule athola noma alahlekelwa ama-electron. Zivame ukuvela njengomphumela wezinqubo ezivamile zokusebenzisa umzimba. Isibonelo, lapho umzimba wakho usebenzisa i-oksijeni, kudala ama-radicals mahhala njengomkhiqizo owodwa futhi umonakalo obangelwa yizi-radicals mahhala kuthiwa 'ukucindezeleka okwenyukayo.'
Kodwa umzimba wakho awusona kuphela umlandu. Ungakwazi futhi ukudalulwa kuma-radicals mahhala avela emithonjeni ehlukahlukene yemvelo efana nemisebe, izidakamizwa, izibulala-zinambuzane, izivolumu, umusi wokubhema nezinye izinto ezingcolisayo.
Kungani Izikhulu Zamahhala Zibi Kangaka?
Lapho usencane futhi unempilo, umzimba wakho wenza umsebenzi omuhle wokusebenzisana nalezi zinhlawulo zamahhala, futhi awuqapheli lutho. Kodwa, uma ungadli kahle, ubhema, noma utholakale emithonjeni eminingi yemvelo yama-radicals yamahhala, ingozi yakho yokulimala kwamaselula kanye nesezikhuphuka. Oh, nokuguga kuthatha isimiso sakho ohlelweni lwakho lokuvikela olukhululekile futhi.
Ama-radicals amahhala awonakalisa amangqamuzana ngokuhamba kwesikhathi, ngakho-ke ekugcineni noma yiluphi uhlangothi lawo amangqamuzana angowakho aluzosebenza ngendlela efanele nakanjani. Isibonelo, izicubu ezixhumeneyo ezibizwa ngokuthi i-collagen iyancipha ngokukhululeka okukhulu okukhululekile, futhi ngenxa yalokho, isikhumba sakho sithola imibimbi eningi. Futhi, izindonga zemithanguzo yakho zingalimaza, futhi ama-cholesterol plaques akha, anganciphisa ukugeleza kwegazi enhliziyweni yakho, ebuchosheni, nakwezinye izitho, noma kubangele i-blood clots.
Ngenxa yokulimala okungase kube khona, ukuvezwa okukhululekile okukhulu kwamahhala kuhlotshaniswa nengozi ekhulayo yezifo eziningi ezingapheli, njengesifo senhliziyo nezinye izinhlobo zomdlavuza. Ngokusobala, kungumqondo omuhle kakhulu wokugwema inani elidlulele lama-radicals mahhala.
Lokho Kuphikisana Nemikhemikhali Nempilo, Ngakho Kanjani Ukudla Okuhlobene Nakho?
Ukudla ukudla okunempilo, izithelo ezimibalabala, kanye nemigodi kungasiza ukulwa nomonakalo omkhulu wamahhala.
Izakhi ezifana ne-vitamin C, i-beta-carotene, i-selenium ne- vitamin E zingasiza ukuvimbela noma ukunciphisa umonakalo obangelwa ama-radicals wamahhala, ngakho-ke abizwa ngokuthi ama-antioxidants. Lezi zondla zitholakala ekudleni okuhlukahlukene, kepha ziphezulu kakhulu emithonjeni yezitshalo. Ngakho lokho kungaba yisinye sezizathu zokudla ukudla okunezithelo nemifino kubaluleke kakhulu empilweni yakho.
Ngempela, ucwaningo lubonisa ukuthi ukudla ukudla okunamandla kuma- antioxidants kuhlotshaniswa nempilo engcono. Yiqiniso, kunezinye izizathu zokuthi kungani abantu abadla kakhulu ngama-antioxidants bangase babe ngcono empilweni. Isibonelo, abantu abadla ngendlela enempilo nabo bavame ukusebenza ngokweqile futhi banamathuba amaningi okugcina ukudla okune-caloric efanele.
Izidakamizwa Zingadliwa Yini Ukulwa Nezikhulu Zamahhala?
Kunezithako eziningi zokudla ezibiza ukuthi ziyi-antioxidants ngoba zenziwe izakhi noma izitshalo ezitshaliwe eziye zabonisa umsebenzi we-antioxidant ebhokisatri. Kodwa, nakuba ukudla okubonakala kucebile kuma-antioxidants kubonakala kuzuzisa, ukuthatha izithako zokuvimbela i-antioxidant akubonakali ukunikeza izinzuzo ezifanayo, ngaphandle kwezimo ezingavamile. Njengenhlanganisela ye-lutein, i-zeaxanthin, nezinye izakhi ezinganciphisa ukuqhuma kokukhubazeka kwe-macular, okuyiyona imbangela ehamba phambili yobumpumputhe kwasebekhulile.
Nakuba izithako zokuvimbela i-antioxidant ngokuvamile zibhekwa njengeziphephile, ezinye izicwaningo zocwaningo ziphakamisa ukuthi ukuthatha izithako ezithile ze-antioxidant zingenza umonakalo omkhulu kunokuhle, okungekho okufunayo uma uzama ukuthola noma ukuhlala uphilile. Ngakho-ke, kunokuba uchithe imali kuma-supplements abizayo, cishe kungcono ukuthenga izithelo, imifino kanye nezinye ukudla okunempilo.
