Chifukwa vitamini mankhwala amakhala opanda ndipo ngakhale zovulaza

Kamodzi Linus loponya anabwera ndi wanzeru, monga iye anaganiza, lingaliro. kusintha imodzi yokha kadzutsa mwachizolowezi anali wautali ntchito za sayansi ndi. Iye anali kale 65, koma iye anali kupita ntchito monga kale. Loponya anaima pa lingaliro kuwonjezera madzi anu lalanje ndi vitamini C. ankaoneka ngati tinali nanu anaganiza kuwonjezera koka-Cola akadali shuga. Koma ngwazi athu anali wotsimikiza kuti iye anali kulondola.

Kodi lingaliro la munthu angathe kugwira misa

Mumagulu sayansi loponya anali ndi ulamuliro unquestioned monga wopambana ziwiri nthawi Nobel Prize (kuphatikizapo umagwirira). Choncho kudya munthu mmodzi mavitamini anayamba ulendo wake wopambana padziko lonse. Kodi ndi njira, ambiri cheered kale sanavutike makampani mankhwala. Panali malumikizanidwe mwachindunji: wotchuka kwambiri ndi katswiri, misa zambiri anakula malonda a mavitamini ndi zowonjezera zakudya. Koma pano pali chododometsa: palibe dziko sayansi sanayese n'komwe pa nthawi kudzipereka kutsimikizira kulondola kwa mfundo Pauling. Mwamwayi, mfundo ntchito zina mavitamini anali olakwika

The motsindika antioxidant katundu

Ndi loponya, zina, wodzazidwa antioxidants akhoza n'chongoletsa ufulu ankafuna kusintha zinthu mopitirira kapena, ngati iwo amatchedwa mu dziko sayansi, mamolekyulu zotakasika kwambiri. katundu antioxidant, malinga ndi asayansi ndi vitamini C, kupatsidwa folic acid, beta-carotene ndi vitamini E.

chiphunzitso fiasco

Komabe, amachita zimenezi zatsopano zonse zimene zinali kunja mmunda chimenechi kwa zaka zambiri, anakumana ndi wolephera. Palibe zotsatira anakhumba sanali zimatheka. Zatsopano ndi ochiritsira ndi zosinthidwa chibadwa makoswe amene jekeseni antioxidants magazi, anapereka chifukwa chomwecho. Makoswe sakanakhoza kukana zovuta zilizonse zikuwononga wa kukalamba thupi onse, matenda aliwonse makamaka.

Pamaziko a mayesero yaitali matenda

Izo zinali kokha pambuyo zinaonekeratu kuti lingaliro la kubetcha pa antioxidant zowonjezera sizikuyenda pa makoswe, asayansi ayamba nthawi yaitali matenda mayesero anthu. maphunziro mfundo anali chiwembu ambiri: odzipereka okwana pamaziko a msinkhu chomwecho, moyo ndi chitukuko chikhalidwe. Ofuna anasankha anawagawa m'magulu awiri pokhapo titachitapo mmodzi amene amalandira zowonjezera zenizeni kwa nthawi yaitali, ndipo osati wina. Choncho, mfundo ya njira awiri akhungu ofufuza mobwerezabwereza anaulula pang'ono olimbikitsa chithunzi.

Phunziro Chifinishi pakati pa gulu 29.000 mu kusuta mozungulira zaka 50, anawulula zotsatirazi: vitamini A, zinatengedwa pa maziko yaitali, akhoza azitaya khansa ya m'mapapo ndi 16 peresenti.
