Oxidation yog kev hloov tshuaj lom neeg uas tuaj yeem tso lub zog. Raws li peb pom tau, qhov kev kub nyhiab ntawm ntoo yog oxidation, thiab kev kub hnyiab ntawm ntoo kom tso tawm cov hluav taws kub thiab lub zog.
Hauv qhov chaw tsis pom, peb lub cev tib neeg kuj raug oxidized txhua lub sijhawm, vim peb xav tau lub zog txhua hnub. Thaum cov tshuaj tiv thaiv oxidation tshwm sim hauv lub cell thiab lub zog tso tawm, cov tshuaj hu ua dawb radical kuj tseem tsim tawm.
Yog li qhov twg dawb radicals los ntawm thiab dab tsi yog cov ua kev puas tsuaj.
Dawb radicals hauv tib neeg lub cev tsuas yog los ntawm cov hauv qab no: UV hluav taws xob: Thaum ultraviolet rays yog irradiated rau cov khoom hauv ntiaj teb, lawv yuav tsim cov nquag nquag oxygen dawb radicals. Cov Hluav Taws Xob: Cov pa oxygen reactive dawb los ntawm hluav taws xob tuaj yeem tsim kev puas tsuaj ntawm tes thiab yog cov teeb meem ntawm DNA puas tsuaj. Kev siv tshuaj lom neeg: feem ntau yog hais txog qee cov tshuaj tua kab, tshuaj tua kab, qee yam tshuaj, thiab lwm yam kev mob siab ntsws: Kev ntxhov siab tuaj yeem ua rau ntshav khiav tsis zoo, nthuav tawm hauv lub xeev hypoxic, thiab txhawb kev tsim khoom dawb dhau. Kev haus luam yeeb: Muaj ntau cov dawb radicals hauv cov luam yeeb thiab tar.
Dawb radicals tuaj yeem ncaj qha lossis tsis ncaj qha ua rau ntau yam teeb meem: Kev laus: Hauv lub cev metabolism hauv tib neeg lub cev, kev rhuav tshem cov radicals dawb ua rau kev laus. Qhov no yog lub hauv paus ntsiab lus ntawm cov dawb radical laus kev tshawb xav. Kab mob hauv lub plawv: Thaum lub plawv nres, feem ntau ntawm kev puas tsuaj rau lub plawv cov leeg yog los ntawm kev tawm ntawm cov dawb radicals tshwm sim los ntawm cov ntshav liab. Cov kab mob qhov muag: Dawb radicals yuav ua rau puas ncaj qha rau lub lens. Cov kab mob ntawm lub hnub nyoog muaj feem cuam tshuam nrog dawb radicals, tshwj xeeb tshaj yog cataracts. Kab Mob Cancer: Ntau cov carcinogens tsim cov dawb radicals hauv cov txheej txheem metabolic, uas tom qab ntawd tua DNA thiab nws thiaj li ua rau mob cancer. Txo lub zog tsis ua haujlwm: dawb radicals ua rau lub cev tsis muaj zog lossis lymphatic system ua rau nws puas tsuaj.
Cas yuav los tiv thaiv oxidation no tiav?
Dawb radicals tuaj yeem tua cov ntaub so ntswg thiab cov hlwb, tshwj xeeb tshaj yog cov DNA hauv lub keeb, ua rau mob rau tib neeg lub cev.
Ultraviolet rays, siab, tshuaj lom neeg, nias ... txhua cov dawb radicals yog tsim kom ze rau peb.
Dawb radicals tsim kev nruam txhua qhov chaw hauv lub cev, thiab tshuaj tua kab mob antioxidant ua si lub luag haujlwm zoo hauv kev txo qis kev puas tsuaj.
Yog lawm, ib yam kom tshab txhais yog dawb radicals tsis puas. Ntau lub cev kev ua haujlwm ntawm tib neeg lub cev kuj yog nyob ntawm cov txiaj ntsig ntawm cov dawb radicals, xws li ntshav khiav, tawm tsam txias, mob hlwb thiab lwm yam.
Qhov twg muaj lub neej, muaj dawb radicals. Yog tsis muaj cov radicals dawb, peb yuav tsis nyob ua ib ke.
Yog li ntawd, qhov uas peb feem ntau hu ua los tiv thaiv oxidation yeej ua tau tswj kev tshuav ntawm oxidation thiab anti-oxidation.
Antioxidant tswv-tshuaj yej polyphenols
Cov tshuaj yej polyphenols suav txog 18% -36% ntawm qhov nyhav nyhav ntawm cov tshuaj yej.
Kev tshawb fawb ntawm cov tshuaj yej polyphenols tau pib thaum xyoo 1950. Nws tuaj yeem tiv thaiv lub cev' s lub cev caj ces DNA los ntawm kev puas tsuaj los ntawm cov dawb radicals thaum lub sijhawm ua tiav.
Cov vitamins yog cov tshuaj antioxidants zoo, txawm li cas los xij, lub zog ntawm tshuaj yej polyphenols nyob deb dua lawv.
Cov tshuaj antioxidant muaj peev xwm ntawm cov tshuaj yej polyphenols yog 6-7 zaug ntawm cov vitamin E thiab 5-10 zaug ntawm cov vitamin C.
Ntawm nimno, qhov tseem ceeb ntawm cov tshuaj yej los tiv thaiv qog noj ntshav, tiv thaiv hluav taws xob thiab tiv thaiv kev laus yog qhov ua los tiv thaiv oxidant tshuaj yej. Yog li ntawd, tshuaj yej polyphenols tseem hu ua" ntuj lub cev muab tshuaj" ;.
Haus tshuaj yej muaj ntau cov txiaj ntsig. Phau Ntawv Teev Sijhawm Teev thiab Time Magazine pom zoo cov tshuaj yej uas yog cov zaub mov ua kom lub zog lossis cov khoom noj zoo ntxiv.
Kuv ntseeg tias raws li lub ntiaj teb' s kev saib xyuas tshuaj yej thiab kev noj qab haus huv txuas ntxiv mus thiab kev tshawb fawb yog tob tob, tshuaj yej raws li kev noj qab haus huv yuav tau txais txiaj ntsig ntau thiab ntau tus neeg.
