Kutheni iipilisi zeepilisi zingabalulekanga kwaye zonakalise

Emva kokuba iLinus Polling ifike ngcamango ecacileyo, wacinga. Utshintsho olulodwa nje kwisidlo sasekuseni oluqhelekileyo lwalufanele ludlulise umsebenzi wenzululwazi. Wayesele sele engama-65, kodwa wayeya kusebenza, njengangaphambili. Ukuvota kwayeka kwimbono yokongeza i-vitamin C kwijusi yakhe ye-orange. Kwakubonakala ngathi sinqume ukuongeza ishukela kwiCoca-Cola. Kodwa iqhawe lethu liqinisekile ukuba lifanelekileyo.

Indlela umntu omnye angabamba ngayo abantu

Kwizenzululwazi zoluntu I-Polling yayinegunya elingenakuphikiswa njengombini wexesha eli-2 lomvuzo weNobel (kubandakanywa nekhemistri). Ngoko kunye nokubonelelwa komntu oyedwa iivithamini zaqala ukulandelelana kwazo kwihlabathi jikelele. Kunoko, kwindlela, ininzi yayivuyiswe ngoshishino olusele luhluphekile. Kwakukho ukulungelelaniswa ngokuthe ngqo: ukugqithiswa ngakumbi kwenzululwazi yaba, ukuthengiswa kwamathamini kunye nezithako ze-biologically zisebenza. Kodwa nantsi into ephazamisayo: akukho nehlabathi lezenzululwazi ngelo xesha lazama ukuzibophezela ukuqinisekisa ukuchaneka kwengcamango yePolling. Njengoko kwavela kamva, umgaqo wokusetyenziswa okungeziwe kwamavithamini kwakungalunganga

Gxi ninisa kwiipropati ze-antioxidant

Ngokutsho kwe-polling, izongezelelo ezizaliswe ngama-antioxidants ziyakwazi ukunciphisa i-radicals yamahhala okanye, njengoko zibizwa kwihlabathi lenzululwazi, i-molecule eyenzayo. Izakhiwo ze-antioxidant, ngokwezenzululwazi, zinevithamini C, i-folic acid, i-beta-carotene kunye ne-vitamin E. Ingozi yokubhenela kuma-radical ekhululekile emzimbeni womntu yafunyanwa kuqala ngumnye umntu waseRochester Institute uRebcca Gershman ngo-1954. Kwiminyaka edluleyo, uDenam Harman, uprofesa onxulumene neSebe lezeMpilo zeZonyango ezivela kwiYunivesithi yaseCalifornia eBerkeley, wabamba le ngcamango. Kwiminyaka emibini kwatyhilwa ukuba i-radicals yamahhala ibandakanya ukungonakaliswa kweeseli zomzimba. Enyanisweni, izizathu ezibalulekileyo zokuguga komzimba kunye nokubonakala kwezifo ezininzi zichongiwe. Ngoku ngoku ixoxa ngeenjongo kunye neengozi zamavithamini. Kwaye, phakathi kwekhulu lama-20, kwacaca kuwo wonke umntu ukuba isondlo sesondlo sihlawulisa umntu onempilo.

Iintshaba eziphambili zomzimba

Sekuqaleni kwee-70-iyeza zichaza ngokucacileyo ubudlelwane be-radicals yamahhala kunye nokuguga komzimba. Nantsi into uDkt. Harman wabhala ngo-1982: "Ukuba sisebenza ukunciphisa izinga le-radicals emzimbeni womntu, oku kuya kubangela ukuncipha kwinqanaba lokuguga komzimba. Kwizandla zethu kuyisitshixo sokuphila ixesha elide. Ndiyathemba ukuba le ngcamango inokufumana iindlela eziza kuphucula kakhulu umgangatho wobomi bethu. "

Le ngcamango yayiyi-fiasco

Nangona kunjalo, ngokusebenza, zonke iimvavanyo ezenziwa kulolu hlobo kumashumi eminyaka alandelayo zihlulekile ngokupheleleyo. Akukho ziphumo ezifunwayo eziye zaphunyezwa. Iingcaphephe kwiirats eziqhelekileyo kunye nezofuzo eziguqulwayo, ezaziphethe igazi lawo, zivelise umphumo ofanayo. Izigodlo azikwazanga ukumelana nesefuthe elibhubisayo lokuguga umzimba ngokubanzi, okanye izifo ngokukhethekileyo.

Ngokusekelwe kwiimvavanyo zesikliniki zexesha elide

Kwaye emva kokuba kucacile ukuba ingcamango yesantya ekuthathe i-antioxidants ayisebenzi kwiigulane, izazinzulu zaqala ukuqhuba izilingo zexesha elide kubantu. Umgaqo wophando ube nesicwangciso jikelele: amavolontiya azimisele ngokubhekiselele kwisigaba esifanayo, indlela yokuphila nokuchuma kweentlalo. Emva koko abaviwa abakhethiweyo bahlulwe ngamaqela amabini anomqathango, omnye wabo wathatha isongezelelo esithile ixesha elide, kanti omnye akazange akwazi. Ngaloo ndlela, ngomgaqo weendlela ezimbini eziyimfama, abaphandi bavakalisa ngokuphindaphindiweyo umfanekiso okhuthazayo.

Ucwaningo lwaseFinland oluqhutywe phakathi kwabangama-29 000 abathathi-nxaxheba be-smoking abaneminyaka engama-50 bafumana oku kulandelayo: i-vitamin A, ethathe ixesha elide, inokunyusa umngcipheko womhlaza wamaphaphu ngama-16 ekhulwini. Abesifazane baseMerika abaneminyaka engama-20 abanomdla wokuba nomdlavuza webele ngenxa yokudla rhoqo kwe-vitamin B9 (i-folic acid.) Okunye, uphando olunzulu lubonisa iziphumo ezidityanisayo. Ngomnye umzamo, abantu abangaphezu kwama-80 bashiye inkampu iminyaka emine ukuba bathathe izongezelelo zabo, ngelo xesha, abathathi-nxaxheba beqela le-placebo bahlala bephila ngokugqibeleleyo ekupheleni kovavanyo. Ngaloo ndlela, uluntu lwenzululwazi lunyanzeliswa ukuba luvume ukuba ingcamango yokuncediswa kwee-antioxidants iyaphoswa ngokupheleleyo.
