Pfungwa yokuti kudya kwakaderera kwemafuta, kwakadai sekubvunzwa kwemakore akawanda zvakadaro nehurumende yeUnited States uye American Heart Association (AHA), inoshanda pakudzivirira atherosclerotic cardiovascular disease iye zvino yave ichirambidzwa. Mumakumi emakore akapfuura, zvidzidzo zvekuchirapa umo mafuta ezvekudya akachengeterwa pasi pe25% zvezuva nezuva makorikori akakundikana kuratidza hutano hwemwoyo.
Makore mashomanana adarika, AHA akanyarara akadonha kukura kwayo kwemafuta ekuderera.
Pane, zvisinei, kune imwechete iyo yakajeka kune uchapupu hwokuti kudya kwakaderera kwemafuta hakubatsiri pakudzivirira chirwere chemwoyo-chikafu cheOrnnish. Zvokudya zveOrnish (uye kudya kwakadaro) hakusi kungogadzirisa mafuta ezvokudya zvakanyanya kwazvo (kusvika pasi pe10% yezuva nezuva) asiwo inoda chero mafuta anogadzirwa anobva mumiti yakasara. Mune zvose mabhuku ezvokurapa uye mumakwikwi anozivikanwa, chirongwa cheOrnish chinoitwa sechakave chichiratidza kubudirira mukudzivirira kuenderera mberi kwekodonary artery chirwere (CAD) uye kunyange pakuita kuti kuve nekuvandudzika kwechokwadi mumakoronary artery plaques .
Icho ichokwadi here? Pasinei nechokwadi chokuti kudya kweAHA-style-yezvokudya zvakakundikana kwakakundikana kudzivirira atherosclerosis, inoita zvinorema zveOnlin-aina yekudya zvinoshanda here?
Chidzidzo cheOrnish
Zvose mabhuku, mawebsite, mafirimu eTV, hurukuro, editorials, mabhuku, nezvimwewo, kuti zvose zvinobudirira zvekudya zveOrnish zvinogona kuteverwa zvakare kune imwe kliniki yekuedzwa, Lifestyle Heart Trial, yakaitwa muma1980 ne1990 na Dr Dean Ornish neboka rake pa California Pacific Medical Center muSan Franciso.
Vakanyoresa varwere 48 (makumi mashanu avo vaiva varume) avo vaiziva CAD. Twenty-eight were randomized to a special program of lifestyle changes which included the fat-restricted, vegetarian diet ornaments, along with smoking firing, meditation and stress management, and program programming .
Vamwe varwere makumi maviri, boka rekutonga, havana kugamuchira chirongwa ichi chekuchengeta mararamiro. Munguva yemakore mashanu ekutevera, varwere vari muchikwata chekudzidza vakawana zviitiko zvishomanana zviitiko zvemoyo kune avo vari muboka rekutonga, uyewo vakave nehuwandu hwe3% muhukuru hwegoni dzavo aronic plaques (kana ichienzaniswa nekuwedzera kwepakiti mune boka rekutungamirira).
Izvo zvichinyanyovhiringidza kufunga kuti umambo hweOrnnish hunovakirwa pane imwe yedzidzo duku. Chimwe chikonzero, pakanga paine kuwedzera kwevarwere panguva iyi yekudzidza, uye varwere ava vakazobviswa pakutsvaga. Kurasikirwa kunonyanya kukosha mune zvidzidzo zviduku kubva pakarasikirwa kwedata kunogona kuchinja zvakanyanya migumisiro. Kukura kwechidiki chekudzidza kwakabudisawo zvakakosha kusiyana kwepakati pemapoka maviri. Semuenzaniso, boka rekudzora raiva nepamusoro pekutsvaira yeholesterol uye LDL cholesterol mararamiro uye vakange vakwegura uye vakaponda kupfuura boka rekurapa. Zvakare, izvi zvinetso zvinowanzoonekwa kudiki kuongororwa kwekliniki, uye dzinoumba matambudziko akaoma mukududzira kusiyana kwezvikamu pakati pemapoka.
Zvinonyanya kukosha, pfungwa yokuti kudya kwaOrnish kunokonzera kushanduka kweatrosclerosis kunonetsa.
Kuenzanisa migumisiro yakasiyana-siyana ye-2-D engiograms yakaitwa panguva dzakasiyana (sezvakaitwa munyaya ino) inonyanya kukanganiswa nekanganiso sezvo zvishoma zvakasiyana mumakona emifananidzo yakanyorwa zvinogona kupa misiyano yakakura mukuverenga kwehukuru hwepakiti. Kunyange kana zviyero zvakadaro zvaiva zvakanyatsojeka-uye zvakanyanya kure-kunyatsoona kuchinja kwe 3% muhukuru hwepakiti hazvikwanisi kuitwa nehupi hwekuvimba ne 2-D angiography. Izvi zvinokanganisa haisi mhosva yevatsvakurudzi-nzira dzakanakisisa dzakanga dzisiripo mumazuva iwayo. (Izvo zviripo nhasi, kana chidzidzo cheOrnnish chichidzokororwa zvakare) Asi izvi zvisinganzwisisiki zvinotambudza uye zvinosvika mumubvunzo mukuru maitiro anowanzoitwa nevanotsigira kuti mishonga yeOrnish inodzokorora atherosclerosis.
Nzira dzakadaro dzedzidzo dzaizoita kuti zvive zvakaoma zvikuru pakudzidza kwakadai seyi kunyange kugamuchirwa kuti ibudiswe nhasi mune rimwe rezvenhau rezvechiremba rezvepamusoro.
Pakupedzisira, kunyange kana mitsara yakataurwa yeOrnish yakashandurwa kuva yakarurama, hazvibviri kuratidza kuti chimwe cheizvi chinobatsira zvakananga kumutambo weOrnish. Izvi ndezvokuti mamwe matanho matatu anoshandiswa kune boka rekudzidza (kusvuta kusvuta, kushandiswa kwepfungwa, uye nguva dzose yekurovedza muviri) zvose zvinozivikanwa kuvandudza migumisiro yemoya kune varwere vane CAD. Maitiro akavandudzwa anoonekwa muboka rekurapa anotsanangurwa nemamwe matanho matatu; chero zvakabatsiro kubva kumutambo weOrnnish pachawo haugoni kuve nokuderedzwa mumuedzo uyu.
Pane kusava nechokwadi kuti chirongwa chinotyisa chekuchengeta mararamiro chinhu chinobatsira kune varwere vane CAD, uye yekudzidza Ornish (iyo, mushure mezvose, yakanzi Lifestyle Heart Trial, uye kwete iyo Ornish Diet Trial) zvechokwadi yakashandisa mararamiro ehutsinye hunochinja. Asi kunyanya mukuona kwekukundikana kwemazana ekudya zvakaderera-mafuta kunobatsira kugadzirisa migumisiro yemoyo mune zvimwe zvidzidzo, zvakanyanya kusava nechokwadi kune zvekuti zvikomborero zvakadini chikamu chezvokudya zvechidzidzo ichi chakaita kuti zvive zvakanaka. Chirongwa chakachengetedzwa chirongwa chechipatara chinoda kudii kupindura mubvunzo uyu.
The Bottom Line
Kubva pamigumisiro yekudzidza kwaOrnnish-muedzo muduku we randomusiki pane izvo zvirevo zvose zvakakurumbira pamusoro pezvokudya zveOrnish zvakagadzirirwa-pfungwa yokuti ultra-low mafuta yemidyo yekudya inovandudza CAD inofanira kuonekwa semafungiro ekufungidzira. Asi ndizvo zvese-i-unproven hypothesis uye kwete chiitiko chakavonekwa. Chidzidzo chitsva chaizoda kugadzirwa kuti chione kana chikonzero chechokwadi.
Uye kana uri kuenda kutevera Ornish-aina yekudya, chenjererai iyo mafuta yemiriwo .
