Ukuhlala uncane futhi unempilo yiphupho labantu abaningi. Noma kunjalo, yonke imvelo emhlabeni wethu ngesikhathi esifanele ifika ekugugeni kancane kancane nokubhujiswa. Nakuba ososayensi abazange bathole indlela efanele yokumisa inqubo yokuguga. Kodwa imvelo isiqinisekisile ukuthi sinendlela yokunciphisa inqubo yokubhujiswa komzimba. Kuphathelene nama-antioxidants - izinto ezinomthelela we-antioxidant. Ama- antioxidants wemvelo atholakala ekudleni.
Imiphumela ye-antioxidants
Inqubo yokuguga umzimba ibangelwa inqubo ebalulekile yamakhemikhali - i-oxidation. Kwenzeka ngaphansi kwethonya lama-particle ngama electron angasetshenziswanga - ama-radicals mahhala. Efuna ipayipi, ama-electron aphula isakhiwo se-athomu, ehoxisa i-particle kuyo. Ngakho indlela yokubhujiswa kwamanye ama-athomu isunguliwe. Ama-electron, ashiye ngaphandle kwembhangqwana, aphinde awonakalise amanye amangqamuzana, athathe i-electron etholakalayo. Ngenxa yalokho, ukusebenza okugcwele komzimba kuphulwa, izifo zivela, ukuguga kuqala.
Futhi ukukhwabanisa komzimba kungase kuqale ekuqaleni futhi kuholele ezinkingeni zempilo esibucayi futhi kufinyelele isikhathi sokuphila. Ama-antioxidants angasetshenziswa ukulwa nale nqubo. Njengoba ukusabela okukhulu okukhululekile kudlula njalo emzimbeni wethu, yena ngokwakhe uveza antioxidants ukulwa radicals mahhala. Ngokuntuleka kwama-antioxidants, umzimba udinga ukusekela ama-antioxidants aqukethwe ekudleni.
Izinhlobo zama-antioxidants emikhiqizweni:
- i-enzymatic (ikhona kuwo wonke amaseli ezitho nezishukela);
- isisindo somzimba esincane (flavonoids, anthocyanins, amaminerali athile namavithamini);
- ama-hormone (androgens, estrogens, progesterone).
Imikhiqizo ecebile kuma-antioxidants
I-antioxidants enamandla kunayo yonke imikhiqizo yi-flavonoids ne-anthocyanins. Iningi lalezi zitho zingatholakala emifinini nasezithelo, ezihlukile kunambitheka omnandi futhi omuncu noma omuncu futhi ube nombala omnyama, obomvu, obomvu noma obomvu. Ezinye izithelo eziphuzi nohlaza ziphinde zinikezwe inombolo enkulu ye-flavonoids ne-anthocyanins.
Qinisekisa abaholi abaphezulu abayisihlanu kokuqukethwe kwama-antioxidants ngamaqembu omkhiqizo:
Amajikijolo:
- i-cranberry;
- i-blueberry;
- i-raspberries;
- i-currant, ikakhulukazi emnyama;
- Strawberry.
Izithelo:
- iplamu emnyama;
- i-prune;
- ezinye izinhlobo zama-apula;
- ama-oranges;
- igromegranate.
Imifino:
- iklabishi;
- ubhontshisi;
- amabhontshisi;
- ikhasi elibomvu;
- isitshalo seqanda.
Amantongomane:
- i-pecans;
- i-walnut;
- ama-hazelnuts nama-hazelnuts;
- i-pistachios;
- ama-alimondi.
Isizini:
- i-parsley eyomile;
- i-turmeric;
- isinamoni yomhlabathi;
- i-clove;
- i-oregano.
Ngaphezu kwalokho, ama-antioxidants atholakala ku-cocoa, ikhofi kanye netiyi. Futhi ngaleyo ndlela, zonke izinhlobo zetiyi ziwusizo kakhulu. Nokho, kufanele uphuze itiye ngokushesha ngemva kokuphuza. Ngemuva kwemizuzu emihlanu, kuyoba nengcosana yama-antioxidants.
Inani lama-antioxidants ekudleni
Okuqukethwe kwama-antioxidants emikhiqizweni yimiphumela yezifundo ezahlukene. Bathi ngisho nangomkhiqizo owodwa okuqukethwe kwe-flavanoids ne-anthocyanins, amavithamini namaminerali angashintsha kuye ngokuthi kuphi nokuthi iziphi izimo umkhiqizo ukhule. Ngaphezu kwalokho, isitshalo ngasinye sinezinhlobonhlobo nezinhlobonhlobo, ezihluke nakwezakhi zabo zamakhemikhali nezakhiwo eziwusizo. Kodwa-ke, kungashiwo ngokuqiniseka ukuthi imikhiqizo equkethe ama-antioxidants ahluke ngokukhanya nokukhanya kombala.
Emzimbeni wathola inani elanele lama-antioxidants, kuyasiza ukugcwalisa ukudla kwakho nemikhiqizo ehlukahlukene yemvelo. Amantongomane, izinongo, amajikijolo, imifino nezithelo kuzokusiza ukuba ukhulise intsha futhi uqinise impilo.
