Umzimba wethu ukhankanywa imihla ngemihla ukukhulula i-radicals-i-athomu okanye i-molecule, ezenza izenzo zingakhokelela kwimiphumo emibi kakhulu. Izinto ezikhokelela ekubukeni kwazo zihluke kakhulu: ukukhanya kwelanga okanye i-X-ray, umoya ongcolileyo ngenxa yecuba okanye ukukhutshwa kwezimoto, kunye nokungabi ncinane - ukungondleki. Kodwa ukuqonda indlela yokukhusela umzimba wakho kuzo zonke ezi zinto kwaye ugcine ukulinganisela kwayo, kufuneka uqonde inkcazo epheleleyo yombono we-antioxidants.
Ama-radicals amahhala ahlala ekhona emzimbeni wethu, kwaye nangona elowo kubo liyingxenye encinci yengxaki, ngokuqokelela okukhulu kunokubangela ingcinezelo, nemiphumo engayiphenduliyo. Ezi ziqulatho zikhokelela kumonakalo kwi-membrane yeseli ye-molecule ye-DNA, ibe enye yezona zinto ezibangela ukuguga kweeseli. Ubungqina be-radicals yamahhala lukhokelela ekuphuhliseni izifo zamapulmonary, cardiovascular and oncological diseases. Kucingelwa ukuba iseli nganye ivelisa malunga ne-10,000 radicals yamahhala ngosuku. Kwaye i-antioxidants ibizwa ukuba ilwa nabo. Abantu abajongene ngokugqithiseleyo ngcamango ye-antioxidants, imenyu yabo iquka iimveliso ezizityebi kulezi zinto, zinokuxhathisa, oko kukusetyenziswa kwezi zokutya okunempilo kunye nezondlo kukuyindlela efanelekileyo yokukhusela impembelelo yeengqungquthela ezinobungozi.
Antioxidants - yintoni na?
Ziyiqela lezinto ezikhusela iiseli zomntu kwimiphumo emibi ye-radicals yamahhala, enokuthi ibenzi kakhulu indlela yokuzivikela ngayo. Ukusuka kwindawo yokujonga imichiza, i-antioxidant nayiphi na into evimbela ukuxhamla kunye nokuphuhliswa kwama-radicals amahhala, ekuthintela ukuba baninzi. Ngomqondo obanzi, i-antioxidants yizinto ezinokulibazisa okanye ukukhusela umonakalo ochaphazelekayo kwizakhiwo ze-biological.
Umzimba wethu unesixhobo esilungeleyo se-antioxidants coenzyme Q10 kunye ne-glutathione, esilwa ngokukhawuleza nemiphumo ye-radicals yamahhala. Ngelishwa, xa uneminyaka yobudala, ukuthotyelwa kokutya okungafaniyo nokungazi kakuhle kwandisa rhoqo amathuba okubhenca kwizinto ezimbi (umsi, umkhonto, ukungcola kwamachiza okutya kunye namanzi), inani kunye nokusebenza kwezixhobo zokuxhatshazwa kwe-antioxidants kunciphisa ukulinganisa ngokwemisebenzi yomsebenzi we-radicals.
Oku kuthetha into eyodwa kuphela: ngokukhula kweminyaka, ukusetyenziswa kokutya okunothambile kwi-vitamin C no-E, i-beta-carotene kunye ne-selenium kuyimfuneko - ezi zizona zixhobo ezinqabileyo zokungasebenzisi i-anti-oxidants, kodwa ziphinde zithuthukise i-physiology yomzimba, zomeleze ukhuselo lwayo kwiintsholongwane, iintsholongwane nezinto ezinobuthi.
Inkqubo yesenzo se-antioxidants
Iindlela zokukhusela zomzimba zingahlula zibe ngamanqanaba amathathu:
- Inqanaba lokuqala liquka zonke izinto ezikhusela ukubunjwa kwama-radicals amahhala. Ingcaciso yabo epheleleyo ithetha ngathi "i-antioxidants yokukhusela" - transferrin, ferritin, hemosiderin, lactoferin, albin.
- Inqanaba lesibini nelisiseko lokukhusela emzimbeni liqinisekisa ukulandelwa kunye nokususwa kwama-radicals okanye ama-radicals asele ayenzileyo. Oku kwenziwa ngoncedo lwe-antioxidants enzymatic - catalase, glutathione peroxidase kunye ne-glutathione reductase.
- Inqanaba lesithathu lokukhusela lihlelwa ngama-enzyme afunyenwe ngokukodwa kumonakalo ngama-radicals amahhala. Lo msebenzi uvela kwi-phospholipase A2, ezinye i-enzyme zeproteolytic, i-DNA-reduction of enzymes, njl.
Uludwe lwezona zinto zithandwa kakhulu:
1. Resveratrol
2. I-Lycopene
3. iPycnogenol
4. Akay Bury
5. Lactoferin
6. I-alpha lipoic acid
7. Melatonin
8. Coenzyme Q10
9. UGinkgo Biloba
10. I-Spirulina
11. Amabhakabhaka
12. ICocoa
13. I-Raspberry
14. I-algae eluhlaza okwesibhakabhaka
Iziqhamo ezomileyo
16. Iidiliya
17. Igromegranate
18. Iwayini elibomvu
Uphando olutshanje lubonisa ukuba isiphumo sabo esihle sanda xa ama-antioxidants amaninzi asetyenziswa kunye. Kulo phawu, umbuzo uvela: "Ngaba kunokwenzeka ukudala i-superantioxidant ekhuselekileyo ikhusela zonke iiseli ezivela kuhlahlo? Kungenxa yokuba zonke ezi zithako zingadibaniswa ngokufanelekileyo ukudala imveliso eya kuba luncedo xa:
- ukutshaya okanye ukutshaya;
- impembelelo yansuku zonke yokungcola komoya, ukukhutshwa kwezimoto, ukusebenza kwimeko enomxholo ophezulu wezinto ezinobuthi, njl.;
- ukukhanya kwelanga;
- nemiphumo emibi yokudibanisa;
- ukwanda komngcipheko wokuvelisa izifo ze-cardiovascular disease, izifo zesibindi, izifo ezigugulayo kunye nezifo ezingenayo i-neoplastic;
- kwi-trimester yokuqala yokukhulelwa ukunciphisa umngcipheko wokungabikho komntwana ongaphantsi kokuzalwa kunye nokungahambi kakuhle;
- ukuthintela bonke abafuna ukuphucula inkqubo yokuguga nokugcina umzimba wabo ngendlela enempilo nangona emva kokufikelela kwiminyaka engama-60;
- ukugcina ulutsha olunamandla, oluqinileyo, olusisigxinxisayo nolulunge ngakumbi kunye nokunciphisa imibimbi.
Izingozi zempilo
Ngamnye wethu uyazi ukuba ukusetyenziswa kokutya okufana ne-blueberries, i-broccoli, ierharnate, izithelo ze-citrus, kunye nokusetyenziswa kwekhofi kunye netiyi eziluhlaza kuyinto ebalulekileyo kakhulu kwaye inqwenelekayo yokutya okunempilo. Kodwa akukho nanye kuthi uyakrokrela ukuba ngamanye amaxesha kubangela ingozi ebomini kwimpilo yomzimba. Oku akusoloko kuhambelana nencazelo epheleleyo yombono we-antioxidants, kodwa oku sele yinyaniso eqinisekisiweyo.
Nangona ukudibaniswa kwama-antioxidants kwizinto ezahlukeneyo zokutya kunye neziphuzo kubonwa njengeluncedo, uphando olwenziwa ngabasosayensi baseMerika beYunivesithi yaseKansas lubonisa ukuba ukusetyenziswa kwansuku zonke ukutya okuphezulu kuma-antioxidants (umzekelo, i-vitamin C kunye ne-E) kunokukhokelela ekutshintsheni kwingozi kunye nezingathandekiyo kwiiseli ze-somatic zomzimba womntu ngokunyusa kakhulu umngcipheko weentlungu kunye nomhlaza.
Iingcali zenzululwazi ziye zaphawula ukuba ukwanda kwe-oksijini kwiiseli kuthintela njani ukusebenza kwazo. Ngokombono wabo, ibhalansi ye-antioxidant iyancipha kakhulu kwaye kwanokuba ukuncipha okuncinci okanye ukunyuka kwimizi yesistim kunokuba nemiphumo emibi kunye nokubaluleka. Iingcali zeMerika zithi ukugqithisa ngokungenangqiqo kwama-antioxidants kunokulimaza kuphela. Okokuqala kubonakala kungabonakali, kodwa kuyinyaniso. Inani elininzi ngokwezinto eziphathekayo kunye nepropatixinanti zinciphisa amandla omzimba wokudlulisa i-oksijini kwiiseli kwaye oku kuphulwa kwindlela ebonakalayo yokubonakalisa emzimbeni womntu okuyimfuneko ekusebenzeni kwayo ngokuqhelekileyo.
Ababhali belo vavanyo bakholelwa ukuba ukunyuka kwamayeza okulwa ne-antioxidants kuthintela umsebenzi wee-enzymes ezithile ezibandakanyeka ekulungiseni iziphene kwi-DNA chain chain eyenzeka ngexesha lokuhlukana kweeseli. Uphononongo luqinisekisa ubungqina bokuba amayeza amaninzi e-antioxidants angabangela iimpazamo kwi-genetic code of cell kwaye adala utshintsho oluthile. Ngenxalenye yalo, iimpazamo kwizinto zeDNA ziyimfuneko yokuphucula izidumbu, kunye nenani leekhente.
Ngoko ke, ngaphambi kokuba uqale ukusebenzisa izongezo zokutya eziqukethe i-antioxidants, kufuneka uqiniseke ukuba umzimba uyawafuna ngokwenene. Kwaye oku kuthetha ukuba kuyimfuneko nje kuphela ukubonisana neengcali, kodwa nokuqhuba uchungechunge lwezihlalutyo kunye nezifundo. Ngakolunye uhlangothi, ukungabikho kwamachiza athile okuxhatshazwayo okubangela ukuba kuphuhliswe izifo ezingasasigxina kunye nezifo ezithintekayo, ukuguga kwangaphambili, ukunyuka okuphezulu kwinqanaba lokuphuhliswa kwezifo zamehlo ezinokukhubazeka, ezifana ne-cataract. Oku kuthetha ukuba kuyimfuneko ukufumana ibhalansi elungileyo ibe yinto enengqiqo kunye nokuqhubekayo ekusebenziseni i-antioxidants. Zidibanise nendlela yokuphila enempilo ziyakukuvumela ukuba ube nesimo esihle nakumdala.
