Ingabe i-vitamin C ingakuthuthukisa ngempela ukuzivikela komzimba? Indlela yokwengeza i-vitamin C ngokunengqondo? Ubani othambekele ekubeni novithamini C? Imibuzo okhathazeke ngayo kakhulu inezimpendulo ezigunyaziwe. "I-Vitamin C kanye Nombiko Wokuzivikela" inikeze isingeniso esiningiliziwe "somsoco wenkanyezi" uvithamini C endaweni yesithupha yeCIIE. Lo mbiko uhlanganiswe "iNational Nutrition Literacy Improvement Plan" ye-China Health Promotion and Education Association ngokusekelwe ocwaningweni lwemibuzo yodokotela, futhi wamema ochwepheshe be-"Sayensi Nobuchwepheshe China" Iqembu lezeMpilo elihlakaniphile leSayensi and Technology Service Group eliholwa nguSolwazi Ma Guansheng weSikole Sezempilo Yomphakathi sasePeking University, futhi lisekelwe yi-Bayer.

I-Vitamin C yaziwa ngokusiza abantu ukulwa ne-"scurvy", kodwa empeleni inezinzuzo eziningi zezempilo. Ngokombiko, uvithamini C ungamelana ne-oxidation, ulawule amasosha omzimba, unciphise i-cholesterol, ukhiphe ubuthi, futhi ukhuthaze ukumuncwa kwe-calcium nensimbi. USolwazi Ma Guansheng weSikole Sezempilo Yomphakathi sasePeking University wethule esithangamini sabezindaba ukuthi ucwaningo lwamanje nge-vitamin C kanye nokugonywa komzimba lukhathazeke kakhulu. Ngawo-1970, usosayensi owazuza uMklomelo kaNobel kabili uLinus. UDkt. Linus Pauling utusa imithamo ephezulu kavithamini C ukuze kukhuliswe amasosha omzimba ukwelapha umkhuhlane ovamile nokuvimbela umdlavuza. Ngakho-ke, uvithamini C kungathiwa usetshenziswa kabanzi ngaphansi kwesiphakamiso sakhe. Ubudlelwano phakathi kukavithamini C kanye nokuzivikela komzimba bekulokhu kuyisihloko esishisayo emibuthanweni yocwaningo lwesayensi. Ucwaningo oluningi luye lwahlola izindlela ezingenzeka ze-vitamin C ekusebenzeni kwamasosha omzimba, okuhlanganisa: kungathuthukisa umgoqo we-epithelial, umsebenzi we-phagocyte; Usizo lwe-T/B lymphocyte ukwanda nokuhlukaniswa, lubambe iqhaza ekuthuthukiseni ukuzivikela komzimba; Ngesikhathi esifanayo, kungase futhi kuthuthukise umsebenzi wethu wokuzivikela komzimba ngokusebenzisa abaxhumanisi abavuthayo noma ezinye izindlela.

UProfesa Ma Guansheng ukhumbuza ukuthi lezi zinhlobo zabantu ekuphileni kulula ukuntula uvithamini C: (1) abantu abangakuthandi ukudla imifino nezithelo. (2) Abantu abakhuluphele. (3) Inani labantu ababhemayo. Ukubhema kubangela ukucindezeleka okwenziwe nge-oxidative futhi kwandisa ukusetshenziswa kwe-vitamin C. (4) Abesifazane abakhulelwe nabancelisayo. Isidingo sabo se-vitamin C sisonke siyakhuphuka. (5) Asebekhulile. Umsebenzi wabo wokugaya ukudla uba buthaka, futhi bathambekele ekubeni bangadli ukudla okwanele okubangela ukuntuleka kukavithamini C. Uma kunesimo sesifo, ukuvuvukala noma impendulo yokucindezeleka kwe-oxidative iyathuthukiswa, ukusetshenziswa kwe-vitamin C emzimbeni kwanda, futhi kulula nokuntula. Ucwaningo olwenziwa ezigulini ezisezibhedlela zithole ukuthi ukusetshenziswa kwe-vitamin C kuvame kakhulu phakathi kweziguli, ngakho-ke ukunakekelwa okukhethekile kufanele kukhokhwe ekwengezeni kwe-vitamin C ezigulini ezibhedlela.

Ucwaningo lwathola ukuthi odokotela abaningi banomkhuba ovamile wansuku zonke we-vitamin C. U-91.8% wabaphenduli bakhetha ukuthatha izithasiselo zikavithamini C nsuku zonke, futhi bakholelwa ukuthi ukuthatha izithasiselo zikavithamini C kungabasiza ukuba balondoloze isimo sengqondo esihle emsebenzini wabo wansuku zonke. Ngaphezu kwalokho, abaningi abaphendulayo bakhetha ukuthatha izithako ze-vitamin C ngesikhathi sezinga eliphezulu lemikhuhlane nezifo ezithathelwanayo. Kodwa-ke, lolu cwaningo luphinde lwathola ukuthi odokotela ngokuvamile bayalazi iqhaza likavithamini C ekuqiniseni amasosha omzimba nokusiza ekwelapheni izifo zokuphefumula, kodwa ulwazi lokuvimbela izifo ezingamahlalakhona ezingathathelaniyo alukanele. Ukwengeza, ukuqondwa kokuthathwa okunconyiwe kanye nokuntuleka kwamaqembu asengozini enkulu kusadinga ukuthuthukiswa. U-Kong Lingzhi, iphini likamongameli kanye nonobhala-jikelele we-China Health Promotion and Education Association, uveze ukuthi eminyakeni yamuva nje, ngokuqhubeka nokugqugquzelwa kwe-"Healthy China Action", ukuqwashisa komphakathi ngezempilo nokudla kuye kwaba ngcono kakhulu. Ukuqwashisa kwabantu nokunaka umsoco nakho kuyanda, okuyinto enhle kakhulu. Nokho, kusenokungaqondi mayelana nokuqashelwa, ukuqonda nokusebenzisa ezinye izakhamzimba. Isibonelo, isakhi senkanyezi "i-vitamin C" idlala indima ebalulekile ekuphileni kwethu, kodwa asikwazi ukungazinaki ukuthi kukhona amaphutha okuqonda nokusebenzisa. Lesi futhi isizathu esibalulekile sokuthi inhlangano ihlanganise i-Vitamin C kanye ne-Immunity Report.
