Ngokuvamile kuhlotshaniswa noshukela namafutha, ukudla okududuzayo - noma ukudla okunethezeka - aziwa ngokuthi ama-caloric. Kodwa, ngokusho kukaJordan LeBel waseCornell University e-United States, ukudla okunama-kilojoule aphansi kungase kufiseleke, kube mnandi futhi kududuze.

Esifundweni samuva² olwenziwa phakathi kwabantu abangu-277, ngaphezu kwe-35% yabaphendulile bathi ukudla okududuza kakhulu, empeleni, ukudla okunekhalori ephansi, ikakhulukazi izithelo nemifino.

U-Jordan LeBel uthi: “Ukudla okunethezekile kunomzimba, ukunambitheka, ukuthungwa, ukukhanga, kanye nesimo somzwelo. Futhi imizwa inganquma ukudla okunethezekile okufunayo. “

Ucwaningo olwethulwe nguJordan LeBel lubonisa ukuthi ukudla okunempilo ngokuvamile kwandulelwa imizwa eyakhayo, okusho ukuthi sidla kakhulu lapho sesivele sisesimweni esihle somzwelo. “Ngokuphambene, lapho sicindezelekile, sithambekele kakhulu ekudleni okunamafutha amaningi noma okushukela,” ephawula.

Ngisho nangaphezulu, ukusetshenziswa kokudla okunekhalori ephansi kudala imizwa eyakhayo. “Ngaphezu kokuba kuhle empilweni, lokhu kudla kuphinde kusebenzele ukuhlala esimweni esihle ngokwengqondo,” eqhubeka.

Ngokusho kwakhe, kungaba kuhle ukubheja emizweni ukukhuthaza abathengi ukuthi baphendukele kakhulu ekudleni okuhle, ngokombono wezempilo yomphakathi. “Uma uyothenga esitolo futhi ulambile, uba nenhliziyo ebuhlungu futhi uvame ukukhetha okungabazekayo,” kusho uJordan LeBel. Ngakho-ke ukubaluleka kokwazana kahle. “

Ukholelwa ukuthi abapheki nabaphathi bezinsizakalo zokudla kufanele bagcizelele kakhulu i-psychology yabathengi. “Ezindaweni zokudlela, ikakhulukazi ezindaweni zokudlela ezisheshayo, konke kwenziwa ukuze kulondolozwe ingcindezi yethu yansuku zonke, njengokuba se-inthanethi nokwenza isinqumo esisheshayo,” usho kanje. Kunalokho, kufanele udale isimo esikumema ukuthi uphumule futhi udle kancane, ngoba udla kancane uma udla kancane. “

Kusukela ngo-1970 kuya ku-2030, isidingo somhlaba wonke senyama sizobe sesiphindeke kabili, sisuka ku-27 kg kuya ku-46 kg umuntu ngamunye. Ukuze kuncishiswe ukucindezela okwandayo okwenziwa imfuyo endaweni ezungezile, kudingeka ushintsho, ngokusho komcwaningi ongumDashi uJohan Vereijke. “Kumele sisuke enyameni siye kwezidumba. Ngakho-ke singahlangabezana nesidingo samaprotheni ngaphandle kokuboleka iplanethi yethu, ”kusho yena.

Indlela enjalo ingenza kube nokwenzeka ukunciphisa ngokuphindwe kathathu noma kane umhlaba osetshenziswayo kanye nenani lezibulala-zinambuzane nemithi elwa namagciwane okudingwa ukutshalwa kwezilwane, ngokwalo chwepheshe wezobuchwepheshe bokudla. "Nokunciphisa kusuka ku-30% kuya ku-40% wezidingo zamanzi okushoyo", uyanezela.

Kodwa u-Johan Vereijke uyazi ukuthi ukunambitheka kukabhontshisi, uphizi kanye nodali kuyaphazamiseka uma kuqhathaniswa nenyama eyanda kakhulu kubantu baseBrazil, abaseMexico namaShayina. "Ikakhulukazi mayelana nokuthungwa: kufanele silawule ukukhiqiza kabusha umphumela wemicu emlonyeni uma sifuna ukukholisa abathengi ukuthi badle inyama encane kanye nemifino eminingi," usho kanje.

Noma kunjalo uhambisa enye indlela engase ibe nethemba: ukwakha imikhiqizo ehlanganisa amaprotheni enyama nalawo ama-pulses.

UJoyce Boye, umcwaningi wezoLimo kanye ne-Agri-Food Canada, uyavuma: “Ukuxuba amaprotheni omdumba neminye imikhiqizo kuyindlela ethembisayo embonini yokucubungula.” Uthi kubalulekile ukwakha izindlela ezintsha “zokukhiqiza kabusha ukudla okuvamile okuthandwa abantu, kanye nokwenza ukudla okusha okuhlukile.”

Kuleli phuzu, uSusan Arnfield, waseNyuvesi yaseManitoba, uyakwamukela ukufika emakethe yemikhiqizo esuselwe kumifino egazingiwe noma ekhukhumele. “Akukhona nje kuphela ukuthi imifino iyindlela ehlukile yamaprotheni ezilwane, ine-fiber eningi yokudla - futhi abantu baseCanada bantula kakhulu kule fibre! Kubabaza.

Umkhulumeli wePulses Canada³, emele imboni ye-Canadian pulse, iqhubekela phambili. UJulianne Kawa ukholelwa ukuthi lezi zinhlamvu kufanele zibe yingxenye yesu lokulwa nokukhuluphala: "Ukudla i-14 g yemifino ngosuku kunciphisa izidingo zamandla ngo-10%.

I-Canada ingumkhiqizi wesithathu ngobukhulu wama-pulses emhlabeni, ilandela i-China ne-India. Kodwa ithumela kwamanye amazwe ingxenye enkulu yokukhiqizwa kwayo.

Amafutha e-Trans ahlotshaniswa nengozi eyengeziwe yokuphazamiseka kwenhliziyo nemithambo yegazi. Ukusetshenziswa kwabo kuphinde kuhlotshaniswe nokubukeka kwezinkinga zokukhula ezinganeni ezincane.

Yilokhu okushiwo u-Hélène Jacques, uchwepheshe wezokondleka kwabantu e-Institute of Nutraceuticals and Functional Foods (INAF).⁴ yaseLaval University, ngokubuyekeza izifundo zesayensi ezibhekene nezingozi zala mafutha empilweni yabantu.

Futhi ukulimala kwamafutha angathinta izingane ngisho nangaphambi kokuba zizalwe. “Abesifazane baseCanada badla kakhulu amafutha ashintshayo futhi asuswa ku-placenta aye ku-fetus. Lokhu kungaba nomthelela ekukhuleni kobuchopho bengane kanye nokubona kwakhe,” kuchaza yena.

Ekhaya, izinsana zisengozini enkulu yokukhubazeka kokukhula, ucwaningo olubonisa ukuthi ubisi lukamama lungaqukatha amafutha ahamba afika ku-7%.

Abantu baseCanada, ompetha abadabukisayo

Abantu baseCanada baphakathi kwabathengi abakhulu bamafutha e-trans emhlabeni, ngisho nangaphambi kwabaseMelika. Angaphansi kuka-4,5% wokudla kwabo kwansuku zonke kwamandla avela kulolu hlobo lwamafutha. Lokhu kuphindwe kane kunalokho okutuswa yi-World Health Organization (WHO), noma ngo-1%.

“Angaphansi kuka-90% wamafutha asetshenziswa kuleli aphuma ekudleni okugaywe yimboni yezokudla. Okunye kuvela ezinyameni ezidliwayo namafutha ane-hydrogenated, ”kuchaza u-Hélène Jacques.

Ecaphuna ucwaningo lwaseMelika, ugcizelela ukuthi ukwanda kwe-2% kwamafutha e-trans ekudleni kuhumusha esikhathini eside kube ukwanda kwe-25% engozini yesifo senhliziyo.
