Nyanzvi dzenguva refu dzave dzichitsvaka nzira dzekudzivirira hutachiona
Munyika yose, cataract ndiyo inokonzera kukanganisa nekurasikirwa kworatidzwa. MuUnited States, vanopfuura 50 kubva muzana yevanhu vose vane makore makumi mapfumbamwe nemakumi mapfumbamwe nevekare vave nekuvhiyiwa kwecataract, vachiita mari inofungidzirwa $ 6.8 mabhiriyoni pagore. Kuvhiyiwa kweCataract ndiyo nzira yakakwana yokurapa chirwere.
Nemhaka yezvishoma zvigadzirwa, vagari venyika dzichiri kusimukira vanowanzokwanisika kutenga chirwere checataract uye vanofanira kutambura kuburikidza nekufambira mberi kwemaitiro lens opacity inoita kuti zvive zvakaoma kukuona pasi pemamiriro ezvinhu nguva dzose asiwo kunyanya zvakaoma kuona usiku kana kuti glare iri dambudziko.
Mune mamwe mazwi, zvakaoma chaizvo (uye zvinotyisa) kune vanhu vane chirwere chekutya usiku.
Pamusana pekushaikwa kwemaitiro ekuvhiya kwecataract munyika dzakawanda munyika yose, nyanzvi mumunda vave vachitsvaga nzira yekudzivirira kukanganisa. Inofungidzirwa kuti kuwanikwa kwechikonzero chekudzivirira chinotadzisa kutanga kwehutachiwana kwemakore gumi kunogona kuita kuti 50 muzana inopera muoneki uye inopinda mutoro. Pari zvino, vazhinji vanotsvakurudza maziso vanofunga kuti kushandiswa kwemishonga inokonzera antioxidants mune imwe nzira kunogona kudzivirira kukanganisa.
A kazhinji inogamuchirwa zvakagadziriswa pamusoro pechirongwa chechechi yakabatana nemakore pegs oxidative kushushikana uye kusanzwisiswa kwe osmotic sechikonzero. Kunyanya kunyanya, kuwandisa kwemvura yakasununguka kunokanganisa lens mapuroteni uye lipids mu epithelium saka kuvharidza lens uye kutungamirira pakufambira mberi kwepacity. Antioxidants yakafanana ne vitamini C uye vitamini E inogadzirisa izvi zvisingabhadharwi zvekare, uye nokudaro zvinoparadza kuparadzwa pasina radicals chikonzero.
Izvozvi, tinoziva kuti lens inoshandiswa inoshandisa mamwe antioxidants se suchaslutein, zeaxanthin, vitamin E, uye vitamini C.
Kutaura chokwadi, zvimwe zvinhu kunze kwekushandiswa kweiiii oxidative uye radicals pasina zvekare zvinobatsirawo mukurudzirwa kwehutachiwana kusanganisira:
- UV light
- kunwa doro
- chirwere cheshuga
- hormone therapy
- kusvuta
- kuneta
Zvinhu zvakadaro zvinowedzera kuwedzera kukanganisa kwehutachiona uye kukanganisa maziso ako ekudzivirira kusakanganisika kana kugadzirisa kukanganisa kwemarara.
Kuchengetedza Utachiona NeAn Antioxidant-Rich Diet
Migumisiro inobva kuSweden yekudzidza yakabudiswa muJAMA Ophthalmology muna 2014 inoratidza kuti kuwanda kwehutachiona kwakaderedzwa pakati pevanhu vanogara vachidya kudya kwe-antioxidant-yakawanda semiriwo mashizha, mbeu yose, uye kofi. Muchidzidzo ichi chikuru chevakadzi vepakati nepakati uye vakwegura, zvinokonzera zvinoshandiswa zvakadai sekusvuta, muviri mashizha index, chiito chemuviri, uye chidzidzo chekudzidzisa chakagadziridzwa, uye zvigumisiro zvakanga zvichiri kuwandisa.
Nemhaka yokuti kuwedzera kwema antioxidants muzvokudya zvevanhu kunobatanidza nehuwandu hwehuwandu hwehutachiona hwekugadzirisa, huri kuedza kufunga kuti antioxidant zvinowedzera zvinogonawo kuderedza ngozi yako yehutachiona, zvakare. Zvisinei, kutsvakurudza kune kana antioxidant zvigadziridzo zvinoshandiswa kudzivirira kukanganisa zvakabereka migumisiro isina kufanira.
Imwe ichangobva kuitwa randomized-control trial yakabudiswa mupepanhau Ophthalmology muna 2014 inoratidza kuti miviri yakawanda inowanikwa mune antioxidant mixtures yakaderedza ngozi ye nyukliya-chirwere checataract-ne9 muzana munguva ye11.2 makore.
Chimwe chidzidzo chinoratidza kuti mune avo vatsvakurudzo vatsva vagara vachidya kudya kwakapfuma mune antioxidants, high-dose antioxidant supplementation inogona kuwedzera kuisa kero yekataract maitiro. Izvi zvinokonzerwa nekutsvaga kunonzi kunofungidzirwa kune pfungwa yokuti mune zvakawanda zvinowedzera, antioxidants inogona kutendeuka zvakare kune pro-oxidants uye inokonzera kuipa kwehutano.
Chikonzero nei munhu mumwechete anokonidyiditi achiwedzera kana kuti mavirtivaminamadziro anoita zvishomanana kudzivirira kukanganisa zvichida zvine chokuita nekuoma kwevanhu metabolism. Kusvika parizvino, kusanganisa kusina kukwana uye kwekugadzira kunogona kukwanisa kubereka antioxidant-pfuma inowanikwa muzvokudya zvine utano.
Uyezve, pane dzimwe nguva dzakawanda zvinodhaka zvekare zvatisati tawana, uye izvi zvinoratidzika kuti antioxidants dzinogona kuita basa guru mukudzivirira kwehutachiona uye mamwe marudzi ezvirwere.
Shoko Rinobva
Kutsvakurudza kunoratidza kuti antioxidant supplements haiti zvishoma kudzivirira kenza uye mwoyo yezvirwere. Zvisinei, kudya kunova nemichero yemashizha, michero yakajeka uye mamwe mishonga ye antioxidants yakabatanidzwa nekuderera kwengozi yekenza uye chirwere chemwoyo. Saizvozvowo, asi kudya kwakanyatsonaka kwakazara mune antioxidants kunogona kubatsira kudzivirira cataract maitiro, ikozvino antioxidant zvinowedzera zvinowanzoita zvishomanana kudzivirira chirwere chacho. Pakupedzisira, kana iwe unotarisira kubhadhara kubatsirwa kwe antioxidants, yako yakanakisa kutengesa ndeyokushandisa antioxidants mukati memamiriro ezvinhu ezvokudya zvinovaka muviri uye usadzivisa kutora antioxidant zvinowedzera zvingangoita zviduku uye zvingatokuvadza.
