Amanye amafutha emifino esiwabheka njengengxenye yokudla okunempilo empeleni akhulisa ingozi yesifo senhliziyo. I-Health Canada kufanele icabange kabusha ngezidingo zokunciphisa i-cholesterol ekudleni, ngokusho kwe-Journal of the Canadian Medical Association.
Ukushintsha amafutha agcwele emithonjeni yezilwane namafutha emifino e-polyunsaturated sekuyinto evamile ngoba angehlisa amazinga e-serum cholesterol futhi asize ekuvimbeleni isifo senhliziyo.
Ngo-2009, i-Health Canada Food Administration, ngemva kokubuyekeza idatha eshicilelwe, yanikeza isicelo esivela embonini yokudla ukuze kubhekwane nenselele yokunciphisa ingozi yesifo senhliziyo ngokukhangisa amafutha emifino nokudla okuqukethe lawa mafutha. Manje lebula ifundeka kanje: “Ukunciphisa ingozi yesifo senhliziyo ngokwehlisa i-cholesterol yegazi.”
"Ukuhlolwa ngokucophelela kobufakazi bamuva nje, kubonisa ukuthi naphezu kwezinzuzo zabo zezempilo ezifunwayo, amafutha emifino acebile ku-omega-6 linoleic acid kodwa uma kuqhathaniswa ne-omega-3 α-linolenic acid awakwazi ukukuthethelela," kubhala uDkt. Richard. Bazinet ovela eMnyangweni Wezesayensi Yezokudla eNyuvesi yaseToronto kanye noDkt. Michael Chu ovela eMnyangweni Wokuhlinza Inhliziyo e-Health Research Institute eLondon.
Amafutha ommbila kanye ne-safflower, acebile ku-omega-6 linoleic acid kodwa ephansi ku-omega-3 α-linolenic acid, awatholakalanga ukuthi azuzise impilo yenhliziyo, ngokusho kokutholwe kwakamuva. Ababhali bacaphuna ucwaningo olwanyatheliswa ngoFebhuwari 2013: "Ukushintsha amafutha agcwele ekudleni kweqembu elilawulayo namafutha e-safflower (ecebile nge-omega-6 linoleic acid kodwa ephansi ku-omega-3 α-linoleic acid) kuholele ekwehleni okukhulu kwe-cholesterol. amazinga (ehle cishe ngo-8% -13%). Nokho, izinga lokufa kwabantu ngenxa yesifo senhliziyo nemithambo yegazi liye landa kakhulu.”
ECanada, i-omega-6 linoleic acid itholakala emafutheni ommbila nasemafutheni kabhekilanga, kanye nokudla okufana nemayonnaise, imajarini, ama-chips namantongomane. Amafutha eCanola namafutha kabhontshisi wesoya, aqukethe kokubili i-linoleic kanye ne-α-linolenic acid, angamafutha avame kakhulu ekudleni kwaseCanada. “Akukacaci ukuthi amafutha anothe nge-omega-6 linoleic acid kodwa aphansi nge-omega-3 α-linolenic acid angayinciphisa yini ingozi yesifo senhliziyo. Sikholelwa ukuthi ukudla okunothe nge-omega-6 linoleic acid kodwa okumpofu ku-omega-3 α-linolenic acid kufanele kukhishwe ohlwini lwama-cardioprotectors,” kuphetha ababhali.
