Ko vhitamini C inogona kunyatso wedzera kusadzivirirwa? Nzira yekuwedzera sei vitamini C zvine musoro? Ndiani anowanzo kushaya vitamin C? Mibvunzo yaunonyanya kunetsekana nayo ine mhinduro dzine chiremera. Iyo "Vitamin C uye Immunity Report" yakapa sumo yakadzama ye "nyeredzi chikafu" vhitamini C panzvimbo yechitanhatu CIIE. Chirevo ichi chakaumbwa ne "National Nutrition Literacy Improvement Plan" yeChina Health Promotion uye Dzidzo Association zvichibva pabvunzo yemibvunzo yevarapi, uye yakakoka nyanzvi kubva ku "Sainzi neTekinoroji China" yakangwara yehutano nyanzvi yeSainzi neTekinoroji Service Group inotungamirwa naProfessor Ma Guansheng weChikoro chePublic Health chePeking University, uye achitsigirwa naBayer.

Vhitamini C yave ichizivikanwa kubatsira vanhu kurwisa "scurvy", asi ine huwandu hwehutano hwakanaka. Maererano neshumo, vhitamini C inogona kuramba oxidation, kudzora hutachiona, kuderedza cholesterol, detoxify, uye kukurudzira kunyura kwecalcium nesimbi. Muzvinafundo Ma Guansheng weChikoro chePublic Health chePeking University akazivisa pamusangano wevatori venhau kuti tsvagiridzo iripo pavhitamini C uye kusadzivirirwa kwave kunetsa zvakanyanya. Muma1970, musayendisiti akahwina Mubairo weNobel kaviri Linus. Dr. Linus Pauling vanokurudzira kuwandisa kwevhitamini C kuti iwedzere kudzivirirwa kurapa dzihwa nekudzivirira gomarara. Naizvozvo, vhitamini C inogona kunzi inoshandiswa zvakanyanya pasi pechikumbiro chake. Hukama pakati pevhitamini C uye kusadzivirirwa kwagara kwave kuri nyaya inopisa mumasainzi ekutsvagisa madenderedzwa. Zvidzidzo zvakawanda zvakatsvaga nzira dzinogona kuitika dzevhitamini C muhutano hwekudzivirira muviri, kusanganisira: inogona kuwedzera epithelial barrier, phagocyte basa; Batsira T / B lymphocyte kuwanda uye kusiyanisa, kuita basa mukusimudzira hutachiona; Panguva imwecheteyo, inogona zvakare kusimudzira immune system yedu kuburikidza neanopisa anopindirana kana mamwe maitiro.

Purofesa Ma Guansheng anoyeuchidza kuti marudzi aya evanhu muhupenyu ari nyore kushaya vhitamini C: (1) vanhu vasingafariri kudya miriwo nemichero. (2) Vanhu vakafuta. (3) Kusvuta kwevanhu. Kusvuta kunokonzera oxidative kusagadzikana uye kunowedzera vhitamini C kushandiswa. (4) Vakadzi vane pamuviri uye vanoyamwisa. Vitamin C yavo yese inoda kuwedzera. (5) Vakwegura. Basa ravo rekudya rinopera simba, uye vanowanzoita kusadya kwakakwana kunokonzera kushomeka kwevhitamini C. Kana pane chirwere chechirwere, kuzvimba kana oxidative kusagadzikana mhinduro inowedzerwa, kushandiswa kwevhitamini C mumuviri kunowedzera, uye zvakare nyore kushaikwa. Zvidzidzo zvakaitwa muvarwere vari muchipatara zvakaona kuti vhitamini C inoshandiswa yakawanda kwazvo pakati pevarwere, saka kunyanya kunofanira kubhadharwa kune vitamini C kuwedzera kune varwere vari muchipatara.

Ongororo iyi yakawana kuti vazhinji varapi vane vhitamini C yemazuva ese yekuwedzera tsika. 91.8% yevakabvunzwa vakasarudza kutora vhitamini C yekuwedzera zuva nezuva, uye vakatenda kuti kutora vhitamini C yekuwedzera inogona kuvabatsira kuchengetedza mafungiro akanaka mubasa ravo rezuva nezuva. Mukuwedzera, vazhinji vakapindura vanosarudza kutora vhitamini C yekuwedzera panguva yekuwanda kwechando uye zvirwere zvinotapukira. Zvakadaro, ongororo iyi yakawana zvakare kuti varapi vanowanzoziva nezve basa revhitamini C mukusimudzira hutachiona uye kubatsira mukurapwa kwezvirwere zvekufema, asi ruzivo rwekudzivirira kwayo zvirwere zvisingaperi zvisingatapukirwe harisati rakwana. Pamusoro pezvo, kunzwisiswa kwekutora kwakakurudzirwa uye kushaikwa kwemapoka ane njodzi zvakanyanya kuchiri kuda kuvandudzwa. Kong Lingzhi, mutevedzeri wemutungamiri uye munyori mukuru weChina Health Promotion and Education Association, akataura kuti mumakore achangopfuura, nekuenderera mberi kwekusimudzira kwe "Healthy China Action", ruzivo rweveruzhinji nezvehutano nekudya rwakavandudzwa zvakanyanya. Kuziva kwevanhu uye kutarisa kune zvinovaka muviri zviri kuwedzerawo, chinova chiitiko chakanaka kwazvo. Zvisinei, kuchine kusanzwisisana pamusoro pekuzivikanwa, kunzwisisa uye kushandiswa kwezvimwe zvinovaka muviri. Semuenzaniso, nyeredzi inovaka muviri "vitamini C" inoita basa rinokosha muupenyu hwedu, asi isu hatigoni kufuratira kuvapo kwayo kwekuziva uye kushandisa zvikanganiso. Ichi zvakare chikonzero chakakosha chekuti sangano rigadzire iyo Vitamin C uye Immunity Report.
