Akatswiri akhala akufufuza njira zothetsera vutoli
Padziko lonse, nthendayi ndiyo yomwe imayambitsa khungu ndi masomphenya. Ku United States, anthu opitirira 50 peresenti ya anthu onse a zaka zapakati pa 80 ndi zaka makumi asanu ndi atatu (80) apita opaleshoni ya cataract, amawononga $ 6.8 biliyoni pachaka. Kuchita opaleshoni ya cataract ndiyo njira yeniyeni yothetsera vutoli.
Chifukwa cha zoperewera, nzika za m'mayiko osauka nthawi zambiri satha kupeza opaleshoni ya cataract ndipo zimayenera kuvutika kupyolera mu lens opacity zomwe zimapangitsa kuti zikhale zovuta kuziwona nthawi zonse komanso zovuta kuziwona usiku kapena pamene pali vuto.
M'mawu ena, ndizovuta (ndi zoopsa) kwa anthu omwe ali ndi vuto la kuyendetsa usiku.
Chifukwa cha kuchepa kochepa kwa opaleshoni ya kachipatala m'mayiko ambiri padziko lapansi, akatswiri m'munda akhala akufufuza njira yothetsera vutoli. Zikuoneka kuti kupezeka kwa njira yowonongeka yomwe imachedwa kuchepa kwa zaka 10 kungachititse kuti pang'onopang'ono 50 peresenti yawonongeke m'masomphenya ndi opaleshoni. Pakalipano, ambiri ofufuza owona amakhulupirira kuti kumwa mowa mwa antioxidants mwa njira ina kungalepheretse nthendayi.
Lingaliro lovomerezeka lovomerezeka kwambiri lokhudzana ndi chitukuko cha nthendayi yokhudzana ndi zaka zakubadwa zokhudzana ndi matenda osokoneza maganizo ndi kusalingani kwa osmotic monga chifukwa. Zowonjezerapo, kuwonjezera pa ufulu radicals kuwononga lens mapuloteni ndi lipids mu epithelium motero obfuscating lens ndi kutsogolo opacity. Antioxidants monga vitamini C ndi vitamini E zimakhazikitsa zowonongeka, ndipo motero zimathetsa chiwonongeko chowombera.
Ndipotu, tikudziwa kuti disolo limakonda kwambiri mankhwala enaake monga antihasidute, zeaxanthin, vitamini E, ndi vitamini C.
Kunena zoona, zinthu zina osati zowonjezereka ndi zowonjezereka zimathandizanso kuti chitukuko chitheke kuphatikizapo:
- Kuwala kwa UV
- kumwa mowa
- matenda a shuga
- mankhwala a hormone
- Kusuta
- kunenepa kwambiri
Zinthu zoterezi zingapangitse kuti vutoli likhale lopweteka kwambiri ndipo limapangitsa kuti diso lanu lisatetezedwe kapena kuwonongeka kwa diso.
Kupewa Matendawa ndi Matenda Okhudzana ndi Antioxidant
Zotsatira za kafukufuku wa Swedish ku JAMA Ophthalmology mu 2014 zikusonyeza kuti kuchuluka kwa cataracts kunachepetsedwa pakati pa anthu omwe nthawi zonse amadya zakudya zowononga antioxidant monga masamba a masamba, mbewu zonse, ndi khofi. Phunziro lalikululi la amayi a zaka zapakati ndi okalamba, kusokoneza mitundu monga kusuta fodya, chiwerengero cha thupi, masewera olimbitsa thupi, ndi msinkhu wa maphunziro adasinthidwa, ndipo zotsatira zidali zofunikira kwambiri.
Chifukwa kuchuluka kwa mankhwala ophera tizilombo toyambitsa matenda m'thupi mwa munthu kumakhala ndi kuchepa kwa chiwongolero cha cataract, zimayesa kulingalira kuti antioxidant supplements akhoza kuchepetsa chiopsezo chotenga matendawa, komanso. Komabe, kafufuzidwe ngati antioxidant supplements akuthandizira kuteteza matenda osokoneza bongo kwachititsa zotsatira zosagwirizana.
Mlandu wina watsopano wodzitetezera mwatsatanetsatane wofalitsidwa mu nyuzipepala ya Ophthalmology mu 2014 ukusonyeza kuti ma multivitamine omwe ali ndi mavitamini oletsa antioxidant amachepetsa chiopsezo cha cataract-mtundu wa cataract-ndi 9% pazaka 11.2.
Kafukufuku wina akusonyeza kuti mu kafukufuku omwe akudya kale zakudya zokhudzana ndi antioxidants, mlingo waukulu wa antioxidant supplementation ukhoza kuonjezera chiwopsezo cha kapangidwe kake. Kupeza kosagwirizana kumeneku kumatanthawuzidwa ndi lingaliro lakuti, mowonjezera, mankhwala ophera antioxidants akhoza kutembenukira ku zowonjezera zowonjezera ndipo zimayambitsa vuto lakumadzi.
Chifukwa chomwe munthu wina wodwala mankhwala ophera tizilombo toyambitsa matenda kapena multivitamin akukonzekera amachitako pang'ono kuti asateteze nthendayi mwina zimakhudza zovuta za thupi. Pakalipano, kuphatikiza kosakanikirana ndi kosakanikirana kungathe kubweretsanso mankhwala oletsa antioxidant okhala ndi zakudya zathanzi.
Kuwonjezera pamenepo, pali mankhwala ambiri ophera antioxidants omwe sitingathe kuwapeza, ndipo mankhwala osadziwikawa omwe amadziwika kuti ali ndi antioxidants amawathandiza kwambiri kupewa matenda a kadoti ndi mitundu ina ya matenda.
Mawu Ochokera
Kafukufuku amasonyeza kuti antioxidant zowonjezerapo zowonjezera zimathandiza kuchepetsa khansa ndi matenda a mtima. Komabe, chakudya chokhala ndi masamba obiriwira, zipatso zokongola komanso magulu ena a antioxidants akhala akugwirizanitsa ndi kuchepa kwa khansa ndi matenda a mtima. Mofananamo, pamene zakudya zabwino zomwe zimakhala ndi antioxidants zingathandize kupewa cataract mapangidwe, zowononga antioxidant zowonjezera mavitamini zingachititse kuchepetsa matendawa. Pamapeto pake, ngati mukuyembekeza kupindulitsa phindu la antioxidants, kupambana kwanu ndiko kudya mankhwala ophera antioxidants mkati mwa zakudya zopatsa thanzi komanso kupewa kumwa mankhwala ophera tizilombo toyambitsa matenda omwe mwina sangakhale ochepa komanso akhoza kuvulaza.
