Trans mafuta akaipa. Vanogona kuwedzera njodzi yehosha yemwoyo, kufa kamwe kamwe, chirwere cheshuga, uye zvichida kunyange chirwere chepfungwa. Mafuta eTrans akabatanidzwa nehunhu hwehasha, kusashivirira, uye kushatirwa.
Trans mafuta anowanikwa munzvimbo imwechete chete mune zvakasikwa: mumafuta emhuka nevanhu. Indasitiri yezvekudya, zvisinei, yakawana nzira yekugadzira mafuta ane muchetura aya nekugadzira mafuta emuriwo. Mukuita uku, kunonzi hydrogenation, maatomu anorongwa patsva kuti aite semafuta emhuka.
Kunyangwe hazvo America ichigara ichidya akawanda emafuta emafuta kubva pazvikafu zvakagadzikiswa zvine chidimbu chehydrogenated oiri, chikamu chechishanu chemafuta anotapurwa mukudya kweAmerica anoenderana nemhuka. Iye zvino maguta akaita seNew York arambidza kushandiswa kwemafuta ane hydrogenated, kushandiswa kwemafuta anogadzirwa ari kudzikira, paine makumi mashanu muzana emafuta ekuAmerica ari kubva muzvigadzirwa zvemhuka.
Ndezvipi zvekudya zvine huwandu hwakakosha hwemafuta ekutengesa? Zvinoenderana nedhipatimendi repamutemo reDhipatimendi reNutrients, chizi, mukaka, yogati, mahamburger, mafuta ehuku, nyama yeTurkey uye imbwa dzinopisa zviri pamusoro pechinyorwa uye zvine mafuta angangoita 1 kusvika 5 muzana.
Iwo mashoma muzana muzana emafuta emafuta idambudziko here? Sangano resainzi rine mukurumbira muUnited States, National Academy of Sciences, rakagumisa kuti chete yakachengeteka kudya kwemafuta ekutengesa i zero.
Mune mumwe mushumo unoshora kudyiwa kwemafuta ekutengesa, masayendisiti aisakwanisa kunyange kugovera muganhu wakakwirira unobvumirwa kudya zuva nezuva, nokuti “chero kudyiwa kwemafuta e<em>trans kunowedzera ngozi yehosha yemwoyo.” Zvinogona kunge zvisina kuchengetedzeka kushandisa cholesterol, zvichiratidza kukosha kwekuderedza zvigadzirwa zvemhuka.
Ongororo yazvino inosimbisa maonero ekuti kudyiwa kwemafuta ekufambisa, zvisinei nekwavanobva kumhuka kana maindasitiri, kunowedzera njodzi yekuva nechirwere chemoyo, kunyanya muvakadzi, sezvazvinoitika. "Nemhaka yekuti kushandiswa kwemafuta kusingadzivisiki mukudya kwakajairika, kusiri-vegan, kuderedza kudyiwa kwemafuta kusvika zero kunoda shanduko huru mumitemo yekudya," inodaro mushumo.
Mumwe wevanyori, mutungamiriri weHarvard University Cardiovascular Programme, akatsanangura nemufaro chikonzero nei, pasinei neizvi, vasingakurudziri kudya kwemiriwo: “Hatigoni kuudza vanhu kuti vasiye zvachose nyama nezvinogadzirwa nemukaka,” akadaro. “Asi taigona kuudza vanhu kuti vanofanira kuva vanodya miriwo. Dai tainge takavakirwa pasainzi chete, taizotaridzika zvakanyanya. ” Masayendisiti haadi kuvimba nesainzi chete, handizvo here? Zvisinei, mushumo wacho unogumisa kuti kushandiswa kwemafuta e-trans fatty acids kunofanira kuderedzwa zvakanyanya sezvinobvira, asi kudyiwa kwezvokudya zvinovaka muviri zvakakosha.
Kunyangwe iwe uri munhu anodya miriwo akasimba, unofanirwa kuziva kuti pane mukaha mumitemo yemazita inobvumira chikafu chine isingasviki 0,5 magiramu emafuta ekutapudza pasevhisi kuti zvinyorwe kuti "trans-fat-free." Chinyorwa ichi chinozivisa veruzhinji zvisiri izvo nekubvumira zvigadzirwa kuti zvinyorwe kuti trans-isina mafuta asi izvo zvisiri izvo. Saka kuti udzivise mafuta ese anotapurwa, cheka nyama uye zvigadzirwa zvemukaka, mafuta akacheneswa, uye chero chinhu chine chidimbu chehydrogenated ingredients, zvisinei kuti zita racho rinoti kudii.
Mafuta asina kucheneswa, akadai semafuta omuorivhi, anofanirwa kunge asina mafuta ekutengesa. Asi yakachengeteka zvikuru manyuko ezvokudya akazara emafuta, akadai semiorivhi, nzungu, uye mhodzi.
