Kazhinji inosanganiswa neshuga nemafuta, zvokudya zvinonyaradza - kana zvinonyaradza zvekudya - dzinozivikanwa kuva caloric. Asi, maererano naJordan LeBel weYunivhesiti yeCornell muUnited States, zvokudya zvakaderera mumakoriyumu zvinogonawo kudiwa, kunakidza uye kunyaradza.

Mukudzidza kwechangobva kuitika² yakaitwa pakati pevanhu ve277, vanopfuura 35% yevakapindura vakati kudya kunonyaradza zvikuru kwaiva, chaizvoizvo, zvokudya zvakaderera-calori, kunyanya michero nemiriwo.

"Chikafu chinonyaradza chine chimiro chemuviri, kuravira kwacho, magadzirirwo acho, kukwezva, uye chimiro chepfungwa," anodaro Jordan LeBel. Uye manzwiro anogona kusarudza chikafu chinonyaradza chaunotsvaka. “

Chidzidzo chakapihwa naJordan LeBel chinoratidza kuti chikafu chine hutano chinowanzo kutangirwa nemanzwiro akanaka, kureva kuti tinodya zvakanyanya kana tatova mune yakanaka manzwiro. “Kune rumwe rutivi, kana takadzvinyirirwa, tinonyanyofarira zvokudya zvine mafuta akawanda kana kuti shuga,” anodaro.

Kunyanya, kudyiwa kwezvikafu zvakaderera zvekoriori kunoburitsa manzwiro akanaka. “Pamusoro pekuita hutano hwakanaka, chikafu ichi chinoshandawo kuti chirambe chiri muchimiro chakanaka chepfungwa,” anoenderera mberi.

Maererano naye, zvingava zvakakodzera kubheja pamanzwiro ekukurudzira vatengi kuti vatendeuke zvakanyanya kune zvokudya zvakanaka, kubva pakuona kwehutano hwevanhu. “Paunenge uchitenga girosari uye uine nzara, unenge wanyanya kugumbuka uye unowanzoita zvisarudzo zvisina mubvunzo,” anodaro Jordan LeBel. Saka kukosha kwekuzivana zvakanaka. “

Anotenda kuti mashefu nemaneja ebasa rekudya vanofanirwawo kusimbisa zvakanyanya papfungwa dzevatengi. "Mumaresitorendi, kunyanya mumaresitorendi echikafu, zvese zvinoitwa kuchengetedza kushushikana kwedu kwezuva nezuva, sekuva online uye kuita sarudzo nekukurumidza," anodaro. Asi, iwe unofanirwa kugadzira mhepo inokukoka iwe kuti uzorore uye udye zvishoma nezvishoma, nekuti iwe unodya zvishoma kana uchidya zvishoma nezvishoma. “

Kubva 1970 kusvika 2030, pasi rose kudiwa kwenyama kunenge kwakapetwa kaviri, kubva pa27 kg kusvika pa46 kg pamunhu. Kuti kuderedze kuwedzera kudzvinyirirwa kunoitwa nezvipfuwo pane zvakatipoteredza, kuchinja kunodiwa, maererano nemuongorori weDutch Johan Vereijke. “Tinofanira kuchinja kubva munyama tichienda kumarimu. Isu taigona kuzadzisa kudiwa kwemapuroteni pasina kuisa pasi redu rechikwereti, ”anodaro.

Maonero akadaro anogona kuita kuti zvibvirire kuderedza nekatatu kana kana pasi penyika inoshandiswa pamwe chete nouwandu hwemishonga inouraya zvipembenene nemishonga inorwisa mabhakitiriya inodiwa nokurima kwemhuka, maererano nenyanzvi iyi yoruzivo rwokugadzira zvokudya. "Uye kuderedza kubva ku30% kusvika ku40% yemvura inodiwa iyo inoreva", anowedzera.

Asi Johan Vereijke anoziva kuti kuravira kwebhinzi, pizi uye nyemba kunotambura kana zvichienzaniswa neiyo nyama iri kuwedzera kufarirwa nevaBrazil, Mexicans neChinese. "Kunyanya maererano nemagadzirirwo: isu tinofanirwa kubata kubereka mhedzisiro yefiber mumuromo kana tichida kunyengerera vatengi kuti vadye nyama shoma uye nembesa," anodaro.

Asi zvakadaro anoendesa imwe nzira inogona kuvimbisa: kugadzira zvigadzirwa zvinosanganisa mapuroteni enyama neaya epulses.

Joyce Boye, muongorori weAgri-Food Canada, anobvuma kuti: “Kusanganisa mapuroteni emumba nezvimwe zvinogadzirwa inzira inovimbisa indasitiri yekugadzira.” Zvakakosha, anodaro, kugadzira nzira itsva “dzekuberekazve chikafu chakajairika chinodiwa nevanhu, uye kugadzira chikafu chitsva chakasiyana.”

Pachinhu ichi, Susan Arnfield, weYunivhesiti yeManitoba, anotambira kusvika pamusika wezvigadzirwa zvichibva pambesa dzakakangwa kana kuzvitutumadza. “Mbeu hadzisi imwe nzira yeprotein yemhuka chete, ine fiber yakawanda mukudya – uye vanhu vekuCanada vari kushomeka kwazvo mufiber iyi! Anodanidzira.

Mutauriri wePulses Canada³, iyo inomiririra Canadian pulse industry, inoenda zvakatopfuura. Julianne Kawa anotenda kuti maruva aya anofanira kunge ari chikamu chechirongwa chekurwisa kufutisa: "Kudya 14 g yemafuta pazuva kunoderedza simba rinodiwa ne10%.

Canada ndiyo yechitatu pakukura mugadziri wemapulses munyika, mushure meChina neIndia. Asi inotumira kunze kwenyika yakawanda yekugadzirwa kwayo.

Mafuta eTrans anosanganiswa nenjodzi yakawedzera yehutano hwemoyo. Kushandiswa kwavo kunobatanidzawo nekuonekwa kwekukanganisa kwekukura muvana vaduku.

Izvi ndizvo zvakataurwa naHélène Jacques, nyanzvi yezvokudya zvevanhu paInstitute of Nutraceuticals uye Functional Foods (INAF) akati.⁴ yeLaval University, nekuongorora zvidzidzo zvesainzi zvine chekuita nenjodzi dzemafuta aya pahutano hwevanhu.

Uye kukuvadza kwemafuta emafuta kunogona kukanganisa vana kunyange vasati vaberekwa. “Vakadzi vekuCanada vanodya zvakanyanya mafuta emafuta uye anotamiswa kubva muberere kuenda kumwana mudumbu. Izvi zvinogona kukanganisa kukura kweuropi nekuona kwemwana,” anotsanangura kudaro.

Mudzimba, vacheche vari panjodzi huru yekuremara mukukura, chidzidzo chinoratidza kuti mukaka waamai unogona kuva nemafuta anosvika 7%.

MaCanada, shasha dzinosiririsa

Vanhu vekuCanada vari pakati pevatengi vakakura vemafuta ekutengesa munyika, kunyangwe pamberi pevaAmerica. Kwete pasi pe4,5% yesimba ravo remazuva ese rekudya rinobva kurudzi urwu rwemafuta. Izvi zvakapetwa kana pane zvinokurudzirwa neWorld Health Organization (WHO), kana kuti 1%.

“Mafuta asingasviki chikamu che90% emafuta anodyiwa munyika anobva muchikafu chinogadzirwa neindasitiri yezvekurima. Zvimwe zvacho zvinobva munyama inodyiwa nemafuta ane hydrogenated, ”anotsanangura kudaro Hélène Jacques.

Achitaura chidzidzo cheAmerica, anosimbirira kuti kuwedzera kwe2% kwemafuta ekutengesa muzvokudya kunoshandura munguva refu mukuwedzera kwe25% mungozi yehutano hwemwoyo.
