Ntau lub hnub nyoog tshwj xeeb ntsig txog kev mob nkeeg tau cuam tshuam nrog kev noj tsawg thiab cov ntshav ntawm tocopherols thiab tocotrienols.Peb tau ua ib qho kev tshuaj xyuas txhawm rau txheeb xyuas cov pov thawj tseem ceeb hais txog: (1) kev sib koom ua ke ntawm kev noj haus thiab cov ntshav ntshav ntawm tocopherols thiab tocotrienols thiab cov hnub nyoog ntsig txog kab mob (osteoporosis, sarcopenia thiab kev paub tsis meej);thiab (2) kev noj zaub mov kom zoo los yog ntxiv nrog tocopherols thiab tocotrienols rau kev kho mob ntawm qhov txawv txav.Qhov kev tshuaj xyuas no suav nrog 51 cov kev tshawb fawb tsim nyog.Cov ntaub ntawv tsis ntev los no qhia txog tias, muab cov txiaj ntsig tsis zoo ntawm kev noj tsawg thiab cov ntshav ntawm cov tocopherols thiab tocotrienols ntawm cov pob txha, cov leeg nqaij, thiab kev paub txog kev ua haujlwm, kev hloov hauv txoj kev ua neej yuav tsum yog lub hauv paus hauv kev tiv thaiv cov hnub nyoog tshwj xeeb ntsig txog kab mob. rau vitamin E-tsis muaj xwm txheej.Kev noj zaub mov zoo tshaj plaws hauv cov neeg laus kom tsis txhob muaj vitamin E tsis txaus thiab nws qhov cuam tshuam tsis zoo, xws li kev mob siab thiab oxidation, yuav tsum ua kom tiav cov hom phiaj kev noj haus tshwj xeeb.Cov hom phiaj no yuav tsum tau mus txog los ntawm: nkag mus rau cov neeg laus cov kev kawm rau cov kev pabcuam noj zaub mov tshwj xeeb rau kev ua tiav thiab / lossis tswj lub cev hnyav (tsis txhob noj zaub mov tsis txaus);nce lawv cov khoom noj uas nplua nuj nyob rau hauv vitamin E, xws li derivatives ntawm oily noob (tshwj xeeb yog hom qoob mog roj), txiv roj roj, hazelnuts, walnuts, almonds, thiab cereals nplua nuj nyob rau hauv vitamin E (xws li cov nplej cultivar nplua nuj nyob rau hauv tocotrienols) los yog noj cov tshuaj vitamin E.Nyob rau hauv cov ntaub ntawv no, vitamin E tuaj yeem raug siv raws li tus kheej txoj hauv kev rau qhov tshwm sim los ntawm pathology los yog ua kom muaj kev noj qab haus huv laus thiab lub neej ntev yam tsis muaj kev cuam tshuam.
