I-radical okwamanje ibizwa ngokuthi i-athomu noma iqembu lama-athomu elinomshini ongenalutho. Mayelana nalezi zinhlayiya kubalulekile ukwazi okulandelayo: zingasebenza futhi zizinzile. Ukuze i-antioxidants esebenzayo ne-radicals yamahhala, ukusabela kwamaketanga kuyizici. Isibonelo, i-peroxide, noma i-lipids oxidation oxidation. Ngenxa yesikhombi se-peroxide se-lipids, esakhiwa yizingqamuzana zamangqamuzana, i-hydroperoxides eyingozi yenzelwa umzimba. Iyiphi indima i-antioxidants edlala? Bahlangana nama-radicals abakhuthele futhi banqamule inqubo ye-chain ye-peroxidation. Kulokhu, i-molecule ye-antioxidant iba yinkimbinkimbi eqinile. Kungenxa yokuzinza kwe-particle lapho i-antioxidant iguqulwa khona ukuthi lolu chungechunge luyehla.
I-oksijini engaphezu kwezicubu. Inani le-oksijini emkhathini cishe cishe ngu-21%. Ngisho nokunyuka okuncane kokugxila kuyoba ukucindezela umzimba. Ngisho ne-ozone, eqinisweni, ukuguqulwa kwe-oksijeni, okuvikela yonke impilo emisebeni ye-UV eyingozi, ingabuye ibe yingozi.
Ukufaka ubuthi ngamathunya. Yeka, nokungcola kwemvelo nakho kwenza uzizwe. I-Mercury yi-liquid evunguza. Futhi yi-fumvu ye-mercury enobuthi. Futhi okuyingozi nakakhulu yiziqu eziphilayo ze-mercury. I-Mercury nezinhlanganisela zayo ezingavamile, ezisetshenziselwa kakhulu ezimbonini eziningi, ngokuthuthwa kwamanzi kuwela phansi emzimbeni wamanzi.
UV-Ray. Ngakolunye uhlangothi, ziwusizo futhi ziyadingeka emzimbeni wethu, ngaphansi kwesenzo sabo emzimbeni, kutholakala i-vitamin D. Odokotela batusa amakamelo okupholisa ukuba "vumela" i-ultraviolet ewusizo endlini, ngoba inezakhiwo ezincelisayo. Futhi ngesikhathi esifanayo ngaphansi kwethonya lama-radicals ama-ultraviolet mahhala akhiwa. I-solarium nayo iyingozi.
Ngemva kokuthola i-tan enhle , ungakwazi ukuguga ngaphambi kwesikhathi.
I-Flavonoids. Kunezinhlobo eziyishumi zama-flavonoids, ezinhlanu zazo ezingenambala, isibonelo, ama-catechins. Ziyinkinga kalula futhi ziguqule umbala. Amaqembu amahlanu ama-flavonoid anemibala, lawa yi-pigments amaqabunga, izimbali, izithelo, amajikijolo.
I-Vitamin E. Ngenye yezinto ezinamandla kunazo zonke zokulwa nemvelo. Manje i-vitamin E ingeziwe cishe kuwo wonke ama-creams. Ngendlela, i-antioxidants yokufakelwa ifana ne-vitamin E.
Coenzyme Q noma u-ubiquinone. Futhi mhlawumbe ingxenye eyaziwa kakhulu yezikhwama. I-Coenzyme Q10 iyaziwa kakhulu. Le vithamini ikhona kuwo wonke amaseli omzimba wethu. Kuze kube yamuva, ososayensi bavame ukukhuluma nge-antioxidant umsebenzi we-vitamin E. Kwakukhona ukuthi i-ubiquinone nayo i-antioxidant enamandla kakhulu.
I-Vitamin C. Ngamanani amancane, futhi, i-antioxidant.
Ama-hormone e-steroid. Kuvela ukuthi ama-hormone ethu ayingxenye ekuzivikeleni kwe-antioxidant yomzimba.
I-hormone thyroxine. Le hormone ikhiqizwa ingubo yegciwane futhi iqukethe iodine. Ngakho-ke, ukuba ne-thyroxine ikhona, iododa iyadingeka.
Selenium. Kuyisici esibalulekile. I-Selenium iyinxenye ye-enzyme, ekhombisa izakhiwo ze-antioxidant.
Ama-amino acids kanye ne-glutathione. Ama-amino acids ayingxenye yama-enzyme. Futhi i-methionine iyi-amino acid ebalulekile, okungukuthi, umzimba awukwazi ukuwukhiqiza. Ngakho, ekudleni kwethu kufanele kube imikhiqizo equkethe i-methionine.
Ukuguga - i-alas - inqubo ayinakugwemeka. Ithinta indlela yokuphila, imikhuba emibi, ukudla okunomsoco. Emashumini eminyaka adlule, imibono engu-200 kanye nezinhloso zokuguga kuye kwahlongozwa. Enye yezindawo zokuqala phakathi kwabo yiyona mbono yamahhala ekhululekile. Ukuqoqwa kwemikhiqizo ye-peroxidation nama-radicals yamahhala kuncishisa umsebenzi we-enzyme, ukuphazamisa umsebenzi wezingqamuzana zamangqamuzana, okwenza kube nokugqamile kwe-pigment - lipofuscin - kumaseli. Le pigment iyinkimbinkimbi ye-fat oxidized fatty acids eneprotheni. Ngaphezu kwalokho, izinga elikhulu lokungaqali ama-acids kanye nokukhushulwa okukhulu kwe-oxidation, ikakhulukazi ukuguqulwa kokuguga kwakha. Ngesikhathi esifanayo nesikhulile, umsebenzi we-enzyme elwa nezinqubo ezilimazayo, nezinye izinto ezivikelayo ziyancipha. Ngakho, umzimba udinga ukuvikeleka okwengeziwe.
Kukhona ubufakazi bokuthi ama- antioxidants anciphisa umphumela wama-carcinogens. Futhi mahhala izinqubo ezinkulu, ngokulandelana, sandla ekuthuthukiseni umdlavuza. Idatha abacwaningi abayitholayo iyaphikisana kakhulu. Kodwa-ke, uma ama-carcinogens esebenza emzimbeni isikhathi eside, imiphumela izobonakala. Futhi lapha, indima ebaluleke kakhulu idlalwe yilokho esikudlayo nokuthi ukudla kuphekwe kanjani. Ukudla okuphephile futhi okuphekwe kahle kuwusizo kuwo wonke umuntu. Lapho ukhala, amafutha aqukethe imikhiqizo ivame ukufutheka ku-160-200 ° C, futhi aphezulu nakakhulu.
Yiqiniso, kule lokushisa, ngisho namafutha angasetshenzisiwe angasetshenzisiwe akhiqizwa futhi aguqulwa abe amafomu ayingozi empilweni. Ngakho-ke, indlela ekahle yokucubungula ukudla ishisa. Futhi amafutha yemifino, ewusizo kakhulu emzimbeni wethu, kufanele asetshenziselwe ukugqoka amasaladi. Nsuku zonke, noma izikhathi eziningana ngosuku, sidla okuthosiwe. Cabanga ngakho. Akulula kakhulu ukuziphoqa ukuba udle inyama ebilisiwe ngekholifulawa ephekwe umbhangqwana, kodwa kuwufanele.
Ama-antioxidants ayingxenye yemikhiqizo yezimonyo. Kodwa lokhu akwanele. Phela, ama-radicals mahhala ahlasela umzimba wonke, hhayi kuphela isikhumba iminyaka. Ukudla kubaluleke kakhulu.
I-Vitamin E itholakala kumafutha yemifino: i-sunflower, umnqumo, ummbila kanye nabanye. Futhi, u-vitamin E ugcwele amagciwane kakolweni. Ngakho-ke, kungcono ukudla isinkwa ekudleni kokugaya noma nge-bran. Ngokuqondene nenani elikhulu lama-carbohydrate emikhiqizweni yefulawa. Kusukela komunye noma ezimbili zombili zesinkwa kuyoba kuhle kakhulu kunokulimaza. Kungcono ukudla amaqebelengwane amancane namanye amaswidi.
I-Flavonoids. Imithombo ye-flavonoids imifino nezithelo, isibonelo, ama-artichokes. I-Catechin iqukethe i-cocoa. Ngakho-ke, kungcono ukunikeza okuthandayo kwi chocolate okubabayo kunokuba ubisi ushokoledi.
I-Selenium ingatholakala ku-kakhukhunathi, i-pistachios, i-garlic.
Iningi lazo zonke i-iodine litholakala olwandle kale, nakwezinye izilwane zasolwandle.
Ubihinon itholakala yonke indawo. Ngendlela, kusukela lat. ubique - yonke indawo, yonke indawo. Ngakho-ke, kunzima kakhulu ukukhuluma ngokuntuleka kwe coenzyme Q.
Imithombo yama-amino acid iyamaprotheni. Ungalahli inyama nesobho. Ngoba kukhona ama-amino acids abalulekile okudingekayo emzimbeni wethu, isibonelo, i-lysine. Le-amino acid itholakala kuphela emathanjeni nasezinqoleni.
