Ma radicals amadzimadzi amakhala osasinthasintha mamolekyu omwe angathe kuwononga maselo m'thupi lanu. Zimapanga ma atomu kapena ma molekyulu atapindula kapena ataya ma electron. Kaŵirikaŵiri zimachitika ngati zotsatira za njira zowonongeka zamagetsi. Mwachitsanzo, pamene thupi lanu limagwiritsira ntchito oksijeni, limapanga zinthu zowonjezereka monga zopangidwa ndi mankhwala ndipo zowonongeka ndi zida zowonjezera zimatchedwa 'oxidative stress.'
Koma thupi lanu lachimake silolokha lokha. Mutha kuwonetsanso kuti pali zinthu zina zachilengedwe zomwe zimachokera ku zinthu zosiyanasiyana zachilengedwe monga ma radiation, mankhwala osokoneza bongo, mankhwala osokoneza bongo, utsi, utsi wa ndudu komanso zonyansa zina.
N'chifukwa Chiyani Anthu Amamaseche Amakhala Oipa Kwambiri?
Ukadali wamng'ono komanso wathanzi, thupi lako limakhala ndi ntchito yabwino kwambiri yogwira ntchito zowonjezera, ndipo sumazindikira chilichonse. Koma, ngati simukudya bwino, kusuta, kapena kuti muli ndi malo ambiri okhala ndi zowonongeka, ufulu wanu wa kuwonongeka kwa makompyuta ndi ziwalo ukukwera. O, ndipo kukalamba kumatengera zovuta pa njira yanu yowonjezera yodzitetezera kwambiri.
Mankhwala osokoneza bongo amawononga maselo pakapita nthawi, motero pamapeto pake maselo awo ndi omwe sangagwire ntchito moyenera komanso moyenera. Mwachitsanzo, timagulu tomwe timagwiritsa ntchito collagen timalephera kuwonongeka, ndipo chifukwa chake, khungu lanu limakhala ndi makwinya ambiri. Ndiponso, makoma a mitsempha yanu akhoza kuonongeka, ndipo mapuloteni a kolesterolini amamanga, omwe amachepetsa kuthamanga kwa magazi kumtima, ubongo, ndi ziwalo zina, kapena kumayambitsa magazi.
Chifukwa cha kuwonongeka, kutuluka kwaulere kwaulere kumakhudzana ndi chiopsezo chowonjezeka cha matenda ambiri, monga matenda a mtima ndi mitundu ina ya khansa. Mwachiwonekere, ndilo lingaliro lokometsetsa kuti mupewe zochuluka zowonongeka kwaulere.
Zomwe Zimaphimba Zamoyo ndi Zaumoyo, Nanga Chakudya Chakudya Chakudya N'chiyani?
Kudya zakudya zathanzi, zipatso zamtengo wapatali, ndi zinyama zingathandize kuthana ndi zina mwachisawawa.
Zakudya monga vitamini C, beta-carotene, selenium ndi vitamini E zingathandize kuchepetsa kapena kuchepetsa kuwonongeka kwazamasamba, choncho amatchedwa antioxidants. Zakudya zimenezi zimapezeka mu zakudya zosiyanasiyana, koma zimakhala zogulitsa kwambiri. Kotero icho chikhoza kukhala chifukwa chimodzi chomwe kudya chakudya chokwanira mu zipatso ndi ndiwo zamasamba ndi kofunikira kwambiri pa thanzi lanu.
Zoonadi, kafukufuku akuwonetsa kuti kudya chakudya chamagulu akuluakulu a antioxidants kumagwirizana ndi thanzi labwino. Inde, palinso zifukwa zina zomwe anthu omwe amadya kwambiri mankhwala ophera antioxidants akhoza kukhala ndi thanzi labwino. Mwachitsanzo, anthu omwe amadya thanzi amakhalanso otanganidwa kwambiri komanso amakhala ndi chakudya choyenera.
Kodi Zakudya Zingakuthandizeni Kulimbana ndi Mavuto Osagwirizana?
Pali zakudya zowonjezera zambiri zomwe zimati ndi antioxidants chifukwa zimapangidwa ndi zakudya zam'mimba kapena zowonjezera zomwe zawonetsa antioxidant ntchito mu labotore. Koma, ngakhale kuti kudya zakudya zopangidwa ndi antioxidants zikuwoneka kukhala zopindulitsa, kutenga mankhwala ophera tizilombo toyambitsa matenda sikuwonekere kuti amapereka phindu lomwelo, kupatula nthawi zambiri. Monga kuphatikiza kwa lutein, zeaxanthin, ndi zakudya zina zomwe zingachepetse kupititsa patsogolo kwa kuchuluka kwa macular, chomwe chimayambitsa ubongo kwa okalamba.
Ngakhale kuti antioxidant zowonjezereka zimayesedwa ngati zotetezeka, kafukufuku wina amasonyeza kuti kutenga antioxidant zowonjezereka zimapweteka kwambiri kuposa zabwino, zomwe sizimene mukufuna ngati mukuyesera kukhala ndi thanzi labwino. Choncho, m'malo mogwiritsa ntchito ndalama zowonjezera zakudya zamagetsi, mwina ndi bwino kugula zipatso, ndiwo zamasamba, ndi zakudya zina zabwino.
