Ukudla kwe-DASH (Dietary Approaches to Stop Hypertension) bekusiza abantu behlise ingozi yesifo senhliziyo ngokuncipha kwamazinga e-cholesterol nomfutho wegazi kusukela ekuqaleni kwawo-1990. Kamuva nje, ukudla kwe-DASH kumenyezelwe njengokudla okuphelele kuZiqondiso Zokudla zango-2010. Ukudla kwe-DASH kubonakala ngokunotha ngezithelo, imifino, okusanhlamvu okuphelele, ubisi olunamafutha amancane, ubhontshisi, amantongomane nembewu. Ukudla kwe-DASH nakho kunamafutha agcwele, okusanhlamvu okucwengiwe, ushukela ongeziwe nenyama ebomvu.

Inyama ebomvu ivamise ukuba "imikhawulo" ekudleni okunempilo ngomzamo wokulawula amafutha agcwele. Kodwa ingabe lokhu kuyadingeka ngempela? Isidingo sokugwema inyama ebomvu ukunciphisa amafutha agcwele ngumyalezo otolikwe kabi ngabezindaba nabezempilo. Yize kungukusikeka kwekhwalithi ephansi yangempela nemikhiqizo yenyama ebomvu esetshenzisiwe iqukethe amazinga aphezulu amafutha agcwele, inyama ebomvu ayiphakathi kwabanikeli abaphezulu abahlanu abakhulu bamafutha agcwele ekudleni kwaseMelika (ushizi ogcwele wamafutha ungowokuqala). Kukhona futhi ukusikeka okungu-29 kwenyama yenkomo eqinisekiswe ukuthi incike yi-USDA. Lokhu kusikeka kunamafutha awela phakathi kwamabele enkukhu namathanga enkukhu. Okunye kwalokhu kusikeka kufaka: i-95-pesenti yenkomo yenkomo enomzimba, umjikelezo ongaphezulu, imbiza yamahlombe, i-loin ephezulu (umugqa) isiteki, izindondo ezincane zamahlombe, i-flank steak, i-tri-tip kanye ne-t-bone steaks.

Idatha yocwaningo ibonisa ukuthi esinye sezizathu eziyinhloko esenza abantu bagweme inyama yenkomo ekudleni kwabo umcabango wokuthi ayinampilo futhi ayiyimbi inhliziyo yakho; naphezu kokuthi ezinye izinhlolovo zibonisa ukuthi iningi labantu baseMelika libika ukuthi lijabulela inyama yenkomo. Ngalolo lwazi enginalo, eminyakeni engu-5 eyedlule njengomfundi we-PhD onomsoco, ngahamba neqembu labaphenyi ePenn State ukuphendula lo mbuzo: Ingabe inyama yenkomo enciphileyo inendawo ekudleni kwe-DASH?

Namuhla, lolo cwaningo ekugcineni lushicilelwe. Futhi ngemuva kokukala nokulinganisa yonke into eyodwa abantu abangama-36 abahlukene bafaka imilomo yabo cishe izinyanga eziyisithupha, sinempendulo eqinile embuzweni wethu: Yebo. Inyama yenkomo ezondile ingafakwa ekudleni kwe-DASH.

Ngemva kokuba kukho kokubili i-DASH ne-BOLD (ukudla kwe-DASH okuno-4.0oz/ngosuku lwenyama yenkomo engenamafutha), ababambiqhaza bocwaningo bathole ukwehla ngamaphesenti angu-10 ku-cholesterol yabo ye-LDL ("embi"). Siphinde sabheka ukudla kwesithathu, ukudla kwe-BOLD+, okwakuphezulu ngamaprotheni (amaphesenti angu-28 engqikithi yamakholori ansuku zonke uma kuqhathaniswa namaphesenti angu-19 ekudleni kwe-DASH kanye ne-BOLD). Ukudla kwe-BOLD+ kufaka phakathi u-5.4oz wenyama yenkomo engenamafutha ngosuku. Ngemuva kokulandela ukudla kwe-BOLD + izinyanga eziyisithupha, ababambiqhaza babhekana nokwehliswa okufanayo kwe-cholesterol ye-LDL njengokudla kwe-DASH ne-BOLD.

Isimo esilawulwa ngokunamandla sesifundo sethu (silinganise futhi salinganisa konke ababambiqhaza abakudlayo futhi umhlanganyeli ngamunye udle ngakunye kokudla okuthathu) kusivumele ukuthi senze isitatimende esiphelele sokuthi inyama yenkomo engondlekile ingafakwa ekudleni okunempilo nenhliziyo futhi ungakujabulela I-4-5.4oz yenkomo engenamafutha ngosuku ngenkathi usahlangabezana nezincomo zamanje zokudla zamafutha agcwele.
