Ntawm cov khoom noj khoom haus nrov siv los ua kom zoo dua kev tawm dag zog los ntawm cov neeg ncaws pob, lycopene, carotenoid pom nyob rau hauv txiv lws suav, yog dav siv, nrog kev tshawb fawb soj ntsuam pov thawj tias cov tshuaj ntshiab lycopene yog cov tshuaj antioxidant muaj zog uas tuaj yeem txo qis kev tawm dag zog lipid peroxidation (ib txoj hauv kev uas dawb radicals puas hlwb los ntawm "nyem" electrons los ntawm lipids hauv cell membranes).
Nyob rau hauv ib txoj kev tshawb nrhiav tshiab, luam tawm nyob rau hauv Phau ntawv Journal of the International Society of Sports Nutrition, cov kws tshawb fawb tsom los tshawb xyuas cov txiaj ntsig antioxidant ntawm lycopene, tab sis tshwj xeeb, lawv tau sib sau ua ke li cas rau cov txiv lws suav hmoov, cov txiv lws suav ntxiv ze rau nws cov zaub mov tseem ceeb uas muaj. Tsis tsuas yog lycopene tab sis ib qho dav dav ntawm micronutrients thiab ntau yam bioactive Cheebtsam.
Nyob rau hauv qhov kev tshawb fawb, ob qhov muag tsis pom kev sib txawv, 11 tus txiv neej kawm tau zoo tau txais peb qhov kev tawm dag zog tag nrho tom qab ib lub lim tiam ntawm kev ntxiv nrog txiv lws suav hmoov, tom qab ntawd ntxiv lycopene, thiab tom qab ntawd cov placebo.Peb cov ntshav kuaj (piv txwv li, tom qab noj, thiab tom qab qoj ib ce) raug coj mus rau txhua qhov kev siv tshuaj, txhawm rau ntsuas tag nrho cov tshuaj tiv thaiv kab mob antioxidant thiab hloov pauv ntawm lipid peroxidation, xws li malondialdehyde (MDA) thiab 8-isoprostane.
Hauv cov neeg ncaws pob, txiv lws suav hmoov txhim kho tag nrho cov peev xwm antioxidant los ntawm 12%.Interestingly, cov txiv lws suav hmoov kho kuj ua rau txo qis ntawm 8-isoprostane piv rau ob qho tib si lycopene ntxiv thiab cov placebo.Cov hmoov txiv lws suav kuj tseem txo qis kev tawm dag zog MDA piv rau cov placebo, txawm li cas los xij, tsis muaj qhov sib txawv ntawm cov tshuaj lycopene thiab cov placebo.
Raws li cov txiaj ntsig ntawm txoj kev tshawb fawb, cov kws sau ntawv tau xaus lus tias cov txiaj ntsig zoo dua cov txiv lws suav hmoov muaj nyob rau hauv antioxidant muaj peev xwm thiab kev tawm dag zog vim peroxidation tuaj yeem raug coj los ntawm kev sib koom ua ke ntawm lycopene thiab lwm yam khoom noj khoom haus bioactive, es tsis yog los ntawm lycopene hauv kev sib cais. hom ntawv.
"Peb pom tias 1-lub lim tiam ntxiv nrog txiv lws suav hmoov zoo txhawb nqa tag nrho cov antioxidant muaj peev xwm thiab muaj zog dua thaum piv rau kev ntxiv lycopene," cov kws sau ntawv ntawm txoj kev tshawb fawb tau hais."Cov qauv no hauv 8-isoprostane thiab MDA txhawb qhov kev xav tias dhau lub sijhawm luv luv, txiv lws suav hmoov, tsis yog hluavtaws lycopene, muaj peev xwm txo qis kev tawm dag zog lipid peroxidation.MDA yog biomarker ntawm oxidation ntawm tag nrho cov lipid pas dej tab sis 8-isoprostane belongs rau F2-isoprostane chav kawm thiab yog ib tug txhim khu kev qha biomarker ntawm radical-induced cov tshuaj tiv thaiv uas tshwj xeeb qhia txog oxidation ntawm arachidonic acid.
Nrog rau lub sijhawm luv luv ntawm txoj kev tshawb fawb, cov kws sau ntawv tau xav txog, txawm li cas los xij, tias kev noj tshuaj ntxiv rau lub sijhawm ntev ntawm lycopene tuaj yeem ua rau muaj txiaj ntsig zoo antioxidant rau cov khoom noj uas raug rho tawm, raws li lwm cov kev tshawb fawb uas tau ua dhau los ntawm ntau lub lis piam. .Txawm li cas los xij, tag nrho cov txiv lws suav muaj cov tshuaj sib xyaw ua ke uas tuaj yeem txhim kho cov txiaj ntsig tau zoo hauv kev sib koom ua ke piv rau ib qho sib xyaw, cov kws sau ntawv tau hais.
