Nthawi zambiri zimagwirizanitsidwa ndi shuga ndi mafuta, zakudya zotonthoza - kapena kutonthoza zakudya - amadziwika kuti ndi caloric. Koma, malinga ndi kunena kwa Jordan LeBel wa pa yunivesite ya Cornell ku United States, zakudya zopatsa mphamvu zopatsa mphamvu zochepa zingakhalenso zokhumbitsidwa, zosangalatsa ndi zotonthoza.

Mu kufufuza kwaposachedwapa² kuchitidwa pakati pa anthu a 277, oposa 35% omwe anafunsidwa adanena kuti zakudya zotonthoza kwambiri zinali, makamaka, zakudya zochepa zama calorie, makamaka zipatso ndi ndiwo zamasamba.

Jordan LeBel anati: “Chakudya chopatsa thanzi chimakhala ndi thupi, kakomedwe, kamangidwe kake, chimakopa, ndiponso chimakhudza maganizo. Ndipo kutengeka mtima kungatsimikizire chakudya chomwe mumachifuna. “

Kafukufuku woperekedwa ndi Jordan LeBel akuwonetsa kuti zakudya zopatsa thanzi nthawi zambiri zimatsogozedwa ndi malingaliro abwino, kutanthauza kuti timadya kwambiri tikakhala kale ndi malingaliro abwino. “Mosiyana ndi zimenezi, tikakhala ndi nkhawa, timakonda kwambiri zakudya zamafuta ambiri kapena shuga,” akutero.

Kuphatikiza apo, kudya zakudya zotsika zama calorie kumabweretsa chisangalalo. "Kuphatikiza pa kukhala ndi thanzi labwino, zakudyazi zimathandizanso kukhalabe ndi maganizo abwino," akupitiriza.

Malinga ndi iye, kungakhale koyenera kubetcha pamalingaliro kulimbikitsa ogula kuti atembenukire kwambiri ku chakudya chabwino, kuchokera pamalingaliro aumoyo wa anthu. Jordan LeBel anati: “Ukagula zinthu ndipo uli ndi njala, umakhala wokhumudwa kwambiri ndipo umakonda kusankha zinthu zokayikitsa. Choncho kufunika kodziwana bwino. “

Amakhulupirira kuti ophika ndi oyang'anira chakudya ayeneranso kutsindika kwambiri zamaganizo a ogula. "M'malesitilanti, makamaka m'malo odyera zakudya zofulumira, chilichonse chimachitidwa kuti tisunge nkhawa zathu zatsiku ndi tsiku, monga kukhala pa intaneti ndikupanga chisankho mwachangu," akutero. M'malo mwake, muyenera kupanga mpweya womwe umakulolani kuti mupumule ndikudya pang'onopang'ono, chifukwa mumadya pang'ono mukamadya pang'onopang'ono. “

Kuyambira 1970 mpaka 2030, kufunika kwa nyama padziko lonse lapansi kudzakhala pafupifupi kuwirikiza kawiri, kuchoka pa 27 kg kufika pa 46 kg pa munthu. Pofuna kuchepetsa kupanikizika kowonjezereka kwa ziweto pa chilengedwe, kusintha kumafunika, malinga ndi wofufuza wachi Dutch Johan Vereijke. “Tiyenera kusintha kuchoka ku nyama kupita ku nyemba. Chifukwa chake titha kukwaniritsa zofunikira zamapuloteni popanda kubwereketsa dziko lathu lapansi, ”akutero.

Njira yoteroyo ingathandize kuchepetsa kuwirikiza katatu kapena kanayi padziko lonse lapansi komanso kuchuluka kwa mankhwala ophera tizilombo ndi maantibayotiki omwe kulima nyama kumafuna, malinga ndi kunena kwa katswiri wa zaumisiri wa zakudya. "Ndipo kuchepetsa kuchokera ku 30% mpaka 40% ya zofunikira zamadzi zomwe zikutanthawuza", akuwonjezera.

Koma Johan Vereijke akudziwa kuti kukoma kwa nyemba, nandolo ndi mphodza kumavutika poyerekeza ndi nyama yomwe imakonda kwambiri anthu a ku Brazil, Mexico ndi Chinese. Makamaka pankhani ya kapangidwe kake: tiyenera kukwanitsa kuberekanso zotsatira za ulusi mkamwa ngati tikufuna kukopa ogula kuti adye nyama yocheperako komanso nyemba zambiri," akutero.

Komabe akupereka njira ina yodalirika: kupanga zinthu zomwe zimaphatikiza mapuloteni a nyama ndi ma pulses.

Joyce Boye, wofufuza za Agriculture ndi Agri-Food Canada, akuvomereza kuti: “Kusakaniza mapuloteni a legume ndi zinthu zina ndi njira yabwino yopangira mafakitale.” M’pofunika, akutero, kupanga njira zatsopano “zopanganso zakudya zozoloŵereka zimene anthu amakonda, ndi kupanganso zakudya zina zatsopano.”

Pa mfundo imeneyi, Susan Arnfield, wa pa yunivesite ya Manitoba, akulandira kubwera pamsika wa zinthu zochokera ku nyemba zokazinga kapena zofufuma. “Sikuti mbewu za nyemba ndi m'malo mwa zomanga thupi za nyama, zilinso ndi michere yambiri m'zakudya - ndipo anthu aku Canada akusowa kwambiri mcherewu! Iye akufuula.

Mneneri wa Pulses Canada³, yomwe imayimira makampani aku Canada pulse, amapita patsogolo. Julianne Kawa amakhulupirira kuti nyembazi ziyenera kukhala mbali ya njira yolimbana ndi kunenepa kwambiri: "Kudya 14 g ya nyemba patsiku kumachepetsa mphamvu zamagetsi ndi 10%".

Canada ndi yachitatu pakupanga ma pulse padziko lonse lapansi, pambuyo pa China ndi India. Koma imatumiza kunja zambiri zomwe zimapanga.

Mafuta a Trans amalumikizidwa ndi chiwopsezo chowonjezereka cha matenda amtima. Kudya kwawo kumagwirizananso ndi maonekedwe a chitukuko cha ana aang'ono.

Izi ndi zomwe Hélène Jacques, katswiri wa zakudya zaumunthu ku Institute of Nutraceuticals and Functional Foods (INAF) adanena.⁴ ya Laval University, powunikanso maphunziro asayansi okhudzana ndi kuopsa kwa mafutawa paumoyo wamunthu.

Ndipo kuvulaza kwa mafuta a trans kungakhudze ana ngakhale asanabadwe. “Azimayi a ku Canada amadya kwambiri mafuta osintha zinthu ndipo amasamutsidwa kuchoka ku chiberekero kupita kwa mwana wosabadwayo. Izi zitha kusokoneza kukula kwa ubongo ndi maso a mwana, ”akufotokoza motero.

Pakhomo, makanda ali pachiwopsezo chowonjezeka cha kulumala, kafukufuku wosonyeza kuti mkaka wa amayi ukhoza kukhala ndi mafuta okwana 7%.

Anthu aku Canada, akatswiri achisoni

Anthu aku Canada ali m'gulu la anthu omwe amadya mafuta ambiri padziko lonse lapansi, ngakhale kuposa aku America. Zosachepera 4,5% za mphamvu zawo zatsiku ndi tsiku zimachokera ku mtundu uwu wamafuta. Izi zikuwirikiza kanayi kuposa zomwe World Health Organisation (WHO) imalimbikitsa, kapena 1%.

“Amafuta osakwana 90 pa XNUMX aliwonse omwe amadyedwa m’dziko muno amachokera ku zakudya zokonzedwa ndi makampani a zaulimi. Zina zonse zimachokera ku nyama zowotcha komanso mafuta a hydrogenated, "akufotokoza Hélène Jacques.

Potchula kafukufuku wa ku America, akuumirira kuti kuwonjezeka kwa 2% kwa mafuta owonjezera m'zakudya kumatanthawuza nthawi yayitali kukhala 25% yowonjezera chiopsezo cha matenda a mtima.
