Ukudla kuyisihluthulelo. Isifo senhliziyo siyisimo esiphuthumayo sezokwelapha lapho ukugeleza kwegazi kuya enhliziyweni kuvaleka kungazelelwe, ngokuvamile ngenxa yokwakheka kwe-cholesterol. Lo mshini obulalayo ungaphansi kwethonya lesifo senhliziyo. Ngenhlanhla, ungakwazi ukuvimbela isifo senhliziyo ngokushintsha izici ezingenampilo zendlela yakho yokuphila. Ukudla kuyisihluthulelo, futhi okunye ukudla kuye kwagqanyiswa ngenxa yezakhiwo zabo ezinempilo yenhliziyo.
Ngokocwaningo olwethulwe e-American Heart Association’s Epidemiology and Prevention/Lifestyle and Cardiometabolic Health Scientific Sessions, amafutha omnqumo angasiza ekunciphiseni ingozi yesifo senhliziyo. Ucwaningo luphinde lwabonisa ukuthi luwusizo esikhundleni sebhotela noma imayonnaise.
"Ucwaningo lwangaphambilini luhlobanise ukusetshenziswa okuphezulu kwamafutha omnqumo ekuthuthukiseni impilo yenhliziyo, ikakhulukazi emazweni aseMedithera lapho ukusetshenziswa kwamafutha omnqumo kuphakeme kakhulu," kusho umlobi oholayo uMarta Guasch-Ferre.
"Umgomo wethu kwakuwukuthola ukuthi ukusetshenziswa kwamafutha omnqumo okwenyuka kuyazuzisa yini impilo yenhliziyo kubantu base-US," kusho uGuasch-Ferre, umcwaningi woMnyango Wezokudla eNyuvesi yaseHarvard. I-Chan School of Public Health eBoston.
Ucwaningo lwaluhilela abesifazane abangu-63,867 namadoda angu-35,512 kusukela ngo-1990 kuya ku-2014. Ekuqaleni kocwaningo, bonke abahlanganyeli babengenawo umdlavuza, isifo senhliziyo, nezinye izifo ezingapheli. Njalo eminyakeni emine, babephendula imibuzo mayelana nokudla kwabo nendlela yokuphila. Abacwaningi bathola ukuthi labo abadla ngaphezu kwengxenye yesipuni samafutha omnqumo nsuku zonke babesengozini ephansi ngamaphesenti angu-15 yokuba nesifo senhliziyo nemithambo yegazi kanye nengozi ephansi ngamaphesenti angu-21 yokuba nesifo senhliziyo.
Ukushintsha isipuni sebhotela, imajarini, imayonnaise, noma amafutha obisi ngenani elifanayo lamafutha omnqumo kunciphisa ingozi yesifo senhliziyo nemithambo yegazi ngamaphesenti amahlanu nesifo senhliziyo ngamaphesenti angu-. Nokho, ukudla amafutha omnqumo engeziwe akuzange kuthinte ingozi yokushaywa unhlangothi.
Nakuba amafutha omnqumo atholakala enenzuzo kakhulu kunebhotela nemajarini, awazange anikeze izinzuzo ezengeziwe kunamanye amafutha emifino anjengommbila, i-canola, i-safflower, nobhontshisi wesoya.
“Olunye ucwaningo oluthakazelisayo lubonisa ukuthi nakuba amafutha omnqumo ayengcono kunamafutha amaningi ezilwane kanye nemajarini, ayengaphakeme kunamafutha emifino emphakathini ocwaningwayo,” kusho uGuasch-Ferre. Lokhu kusho ukuthi esikhundleni sanoma yiluphi uhlobo lwamafutha ezilwane namafutha emifino, okuhlanganisa amafutha omnqumo kanye namanye amafutha, kungaba isu elihle lokuthuthukisa impilo yenhliziyo nemithambo yegazi.
Abacwaningi baqaphele ukuthi izinhlobo eziningi zemajarini zaziqukethe amanani abalulekile we-trans fatty acids lapho ucwaningo luqala ngo-1990, ngakho-ke imiphumela ingase ingasebenzi kumajarini yemifino etholakalayo manje. Imiphumela nayo ibe ngeyokubuka, okusho ukuthi ayifaki ubufakazi bembangela.
Kodwa-ke, izifundo ezincane zokungenelela zibonise ukuthi ukufaka esikhundleni samafutha ezilwane ngamafutha omnqumo kunomphumela onenzuzo emazingeni amafutha egazi. "Kudingeka ucwaningo olwengeziwe ukuze kuhlolwe izindlela ezikhona kule nhlangano, kanye nemiphumela yamanye amafutha emifino empilweni yenhliziyo," kusho uGuasch-Ferre.
Izimpawu zokuhlaselwa yinhliziyo zingabandakanya:
- Ubuhlungu besifuba - kungase kuzwakale sengathi isifuba siyampintsha noma sicindezelwa into esindayo, futhi ubuhlungu bungasakazeka busuka esifubeni bufike emhlathini, entanyeni, ezingalweni nasemhlane.
- Ukuphefumula okudidekile
- Ukuzizwa ubuthakathaka noma isiyezi, noma kokubili
- Ukukhathazeka okukhulu.
- Kubalulekile ukuqaphela ukuthi akuwona wonke umuntu ozwa ubuhlungu obukhulu besifuba.
