Zamkatimu
Anthu ambiri amaganiza kuti thupi likamadzadza ndi mavitamini, limakhala lathanzi, ndipo chitetezo cha mthupi chimalimba. Koma, kuchuluka kwa ena mwa iwo kumatha kukhala ndi zotsatira zoyipa, chifukwa chake ma pathologies osiyanasiyana amayamba kukula.
Mavitamini anapezedwa ku dziko ndi munthu wina dzina lake Linus Pauling, amene amakhulupirira mphamvu zawo zozizwitsa. Mwachitsanzo, adanena kuti ascorbic acid imatha kuletsa kukula kwa zotupa za khansa. Koma mpaka pano, asayansi atsimikizira zotsatira zawo zosiyana kotheratu.
Mwachitsanzo, kafukufuku wochuluka wachitika amene watsutsa zimene Pauling ananena kuti vitamini C ingateteze ku matenda a m’mapapo ndi khansa. Ntchito zamakono za asayansi zatsimikizira kuti zinthu zambiri m'thupi la munthu zimakhudza chitukuko cha matenda aakulu ndi oncology.
Kuchuluka kwawo kumatha kuchitika ngati munthu atenga kukonzekera kwa vitamini.
Kugwiritsa ntchito mavitamini opangira sikungathandizire thupi
Pakhala pali maphunziro ambiri omwe atsimikizira kuti mavitamini oterowo sakufunika ndi munthu, chifukwa palibe phindu kwa iwo. Komabe, akhoza kuperekedwa kwa wodwala amene satsatira mlingo wofunikira wa zakudya zabwino.
Komanso, mopitirira muyeso akhoza kukhala ndi zotsatira zoipa pa maselo a thupi ndi kuyambitsa chitukuko cha matenda osiyanasiyana.
Pauling, yemwe adamwa kwambiri ascorbic acid, adamwalira ndi khansa ya prostate. Zomwezo zinachitikanso kwa mkazi wake, yemwe adapezeka ndi khansa ya m'mimba (iyenso adadya mlingo waukulu wa vitamini C).
Machiritso ozizwitsa a matenda onse
Nthawi zonse komanso nthawi zonse anthu adatenga ascorbic acid, ngakhale panalibe kufunikira kwachangu. Komabe, malinga ndi kafukufuku wamkulu wazachipatala wa nthawi yathu (ntchito ya akatswiri azachipatala aku America ochokera ku yunivesite ya New York), yomwe idasanthula ntchito zambiri zasayansi pazakudya zamavitamini kuyambira 1940 mpaka 2005, zidapezeka kuti vitamini C sichithandiza kuchiza chimfine ndi zina. matenda okhudzana. pathology ndi iye. Zonse zomwe zanenedwa pa izi ndi nthano chabe.
Kuonjezera apo, olemba kafukufukuyu amawona kuti mankhwalawa sayenera kugwiritsidwa ntchito ngati njira yodzitetezera, chifukwa zotsatira za izi zimakhalabe zokayikitsa.
Malinga ndi zotsatira za kafukufuku waposachedwa, zatsimikiziridwa kuti mawonekedwe a piritsi a vitamini C amatsogolera ku overdose. Zotsatira za izi ndi miyala ya impso ndi maonekedwe a mtundu wina wa khansa.
Choncho, mu 2013, bungwe la American Health Association linanena kuti odwala khansa asiye kumwa mankhwalawa. Izi zidachitika pambuyo poti zotsatira za kafukufuku zikuwonetsa kuti wothandizila uyu amakhazikika m'maselo a khansa.
Palibe chifukwa chokhala wamanjenje
Monga mukudziwa, mavitamini a B amathandizira kukhazika mtima pansi. Zitha kupezeka muzakudya zambiri, kotero ngati munthu ali ndi zakudya zopatsa thanzi, amazipeza mokwanira. Palibe chifukwa chopangira mavitamini opangira mavitamini. Koma, ngakhale izi, ambiri amatengabe zinthu izi ngati mapiritsi. Ngakhale zilibe ntchito. Anatero asayansi a ku United States National Institutes of Health, omwe anachita kafukufuku posachedwapa.
Pogwiritsa ntchito mankhwalawa, mutha kudziunjikira kwambiri vitamini B m'thupi, zomwe sitinganene za chakudya. Ngati kuchuluka kwake kupitilira muyeso, ndiye kuti zovuta zapakati pa mitsempha zimatha kuchitika. Asayansi akuchenjeza kuti chiwopsezo cha kufa ziwalo pang'ono ndi chachikulu. Choopsa kwambiri ndikutenga vitamini B6, ndipo ndi gawo la pafupifupi ma multivitamin complexes.
Mankhwala omwe ali ndi zotsatira zosiyana
Beta-carotene ndi vitamini A (ma antioxidants ena ambiri) ankaonedwa kuti ndi abwino kupewa khansa. Iwo adalimbikitsidwa mofunitsitsa ndi makampani opanga mankhwala.
Pakhala pali maphunziro pazaka zomwe zalephera kutsimikizira izi. Zotsatira zawo zidawonetsa zosiyana. Mwachitsanzo, bungwe la National Cancer Institute la ku United States linapenda anthu osuta amene amamwa vitamini A ndi amene sanamwe.
Poyamba, anthu ambiri anapezeka ndi khansa ya m’mapapo. Chachiwiri, chiopsezo chotenga khansa chinali chochepa kwambiri. Kuphatikiza apo, kuchuluka kwa zinthu m'thupi kumabweretsa kusokonezeka kwa chitetezo chamthupi. Muzamankhwala, chodabwitsachi chimatchedwa "antioxidant paradox".
Maphunziro ofanana apangidwa ndi anthu ogwirizana ndi asibesitosi. Mofanana ndi osuta fodya, amene amamwa beta-carotene ndi vitamini A anali ndi chiopsezo chachikulu chodwala khansa m’tsogolomu.
Antivitamin
Ankakhulupirira kuti vitamini E akhoza kuchepetsa chiopsezo cha khansa, koma kafukufuku waposachedwapa watsimikizira mosiyana. Ntchito yazaka khumi ya asayansi ochokera ku mayunivesite atatu ku California, Baltimore ndi Cleveland, omwe adawona maphunziro 35, adapereka zotsatira zachilendo.
Zikuoneka kuti kudya kosalekeza kwa vitamini E wambiri kumawonjezera chiopsezo chokhala ndi khansa ya prostate.
Komanso, akatswiri pa Mayo Clinic, yomwe ili ku Minnesota, anatsimikizira kuti kuchulukirachulukira kwa mankhwalawa kumayambitsa kufa msanga mwa anthu omwe ali ndi matenda osiyanasiyana (kugonana ndi zaka zilibe kanthu).
Vitamini ndi mineral complex
Kuyambira theka lachiwiri la zaka zapitazi, mapiritsi okhala ndi vitamini ndi mineral complex amaonedwa kuti ndi njira yothetsera matenda onse. Komabe, kafukufuku waposachedwapa wasonyeza kuti sizili choncho nkomwe.
Akatswiri a ku Finnish, omwe adawona amayi zikwi makumi anayi kwa zaka 25 omwe adatenga multivitamin complex, adapeza kuti pakati pawo chiopsezo cha kufa msanga chikuwonjezeka. Chifukwa cha ichi chinali matenda osiyanasiyana obwera chifukwa cha kuchuluka kwa vitamini B6, chitsulo, nthaka, magnesium ndi kupatsidwa folic acid m'thupi.
Koma akatswiri a ku yunivesite ya Cleveland atsimikiza kuti 100 magalamu a sipinachi yatsopano ali ndi zigawo zothandiza kwambiri kuposa piritsi limodzi la multivitamin complex.
Kuchokera pazomwe tafotokozazi, tinganene kuti ndi bwino kusamwa mankhwala opangira. Chilichonse chofunikira m'thupi la munthu chili m'zakudya zanthawi zonse. Mavitamini amafunikira kokha kwa odwala omwe akudwala kwambiri pakagwa mwadzidzidzi.
