Mamwe mafuta emiriwo atinoona sechikamu chekudya kune hutano anowedzera njodzi yechirwere chemoyo. Hutano Canada inofanirwa kufunga zvakare nezvekudya cholesterol-kudzikisa zvinodiwa, maererano ne Journal of the Canadian Medical Association.
Kutsiva mafuta akazara kubva kumhuka nemafuta emuriwo ane polyunsaturated yave tsika yakajairika nekuti inogona kuderedza serum cholesterol mazinga uye kubatsira kudzivirira chirwere chemoyo.
Muna 2009, Health Canada's Food Administration, mushure mekuongorora yakadhindwa data, yakapa chikumbiro kubva kuindasitiri yezvekudya kugadzirisa dambudziko rekudzikisa njodzi yechirwere chemoyo kuburikidza nekushambadza kwemafuta emiriwo uye chikafu chine mafuta aya. Chiratidzo chacho zvino chinorava, kuti: “Kuderedza ngozi yehosha yemwoyo kupfurikidza nokuderedza cholesterol yomuropa.”
"Kunyatsoongorora kwehuchapupu huchangobva kuitika, zvisinei, kunoratidza kuti pasinei nevanoda kubatsirwa kwehutano, mafuta emiriwo akapfuma mu omega-6 linoleic acid asi ane urombo mu omega-3 α-linolenic acid haagoni kururamisa," Dr. Richard anonyora. Bazinet kubva kuDhipatimendi reNutritional Sciences paYunivhesiti yeToronto uye Dr. Michael Chu kubva kuDhipatimendi reCardiac Surgery paHealth Research Institute muLondon.
Chibage uye mafuta emafuta, ayo akapfuma mu omega-6 linoleic acid asi yakaderera mu omega-3 α-linolenic acid, haana kuwanikwa kuti abatsire hutano hwemoyo, maererano nezvakawanikwa munguva pfupi yapfuura. Vanyori vanotaura chidzidzo chakabudiswa munaFebruary 2013: "Kutsiva mafuta akazara mukudya kweboka rekutonga nemafuta emafuta (akapfuma mu omega-6 linoleic acid asi yakaderera mu omega-3 α-linoleic acid) zvakakonzera kuderera kukuru kwecholesterol. mazinga (akadonha ne8% -13%). Zvisinei, nhamba yevanhu vanofa nehosha yemwoyo nehosha yemwoyo yakawedzera zvikuru.”
MuCanada, omega-6 linoleic acid inowanikwa muchibage nemafuta esunflower, pamwe chete nezvokudya zvakaita semayonesi, majarini, machipisi, uye nzungu. Canola nemafuta esoya, ane zvose linoleic uye α-linolenic acids, ndiwo mafuta anonyanya kuwanikwa mukudya kweCanada. “Hazvizivikanwe kana mafuta akapfuma mu omega-6 linoleic acid asi aine omega-3 α-linolenic acid anogona kuderedza njodzi yechirwere chemoyo. Isu tinotenda kuti zvikafu zvakapfuma mu omega-6 linoleic asidhi mu omega-3 α-linolenic acid zvinofanirwa kubviswa kubva pane rondedzero ye cardioprotectors, "vanyori vakapedzisa.
