Zakudya za DASH (Dietary Approaches to Stop Hypertension) zakhala zikuthandiza anthu kuchepetsa chiopsezo cha matenda a mtima ndi mitsempha yamagazi mwa kuchepetsa mafuta m'thupi komanso kuthamanga kwa magazi kuyambira kumayambiriro kwa zaka za m'ma 1990. Posachedwapa, chakudya cha DASH chinalengezedwa monga zakudya zonse mu Malangizo a Zakudya za 2010. Chakudya cha DASH chimadziwika ndi kukhala ndi zipatso, ndiwo zamasamba, mbewu zonse, mkaka wopanda mafuta ambiri, nyemba, mtedza, ndi mbewu. Zakudya za DASH zimakhalanso ndi mafuta ochepa kwambiri, tirigu woyengedwa, shuga wowonjezera, ndi nyama yofiira.

Nyama yofiira nthawi zambiri imakhala "yopanda malire" mu chakudya chopatsa thanzi poyesa kuwononga mafuta okhuta. Koma kodi izi ndizofunikiradi? Kufunika kopewa nyama yofiira kuti muchepetse mafuta okhuta ndi uthenga womwe watanthauziridwa molakwika ndi atolankhani komanso akatswiri azaumoyo. Ngakhale kudulidwa kocheperako komanso zopangidwa ndi nyama yofiira zimakhala ndi mafuta ochulukirapo, nyama yofiira siyomwe ili pakati pa asanu omwe amapereka mafuta okwanira ku America (tchizi wathunthu ndi nambala wani). Palinso mabala 29 a ng'ombe omwe amatsimikiziridwa kuti ndi oonda ndi USDA. Mabala awa ali ndi mafuta omwe amagwera pakati pa mabere a nkhuku ndi ntchafu za nkhuku. Zina mwazodulazi ndi izi:

Kafukufuku akuwonetsa kuti chimodzi mwazifukwa zazikulu zomwe anthu amapewera ng'ombe m'zakudya zawo ndikuti ndizosavulaza komanso zoyipa mumtima mwanu; ngakhale kuti kafukufuku wina akuwonetsa kuti anthu ambiri aku America akuti akusangalala ndi ng'ombe. Ndili ndi chidziwitsochi, zaka 5 zapitazo monga wophunzira wa PhD wathanzi, ndinayamba ndi gulu la ofufuza ku Penn State kuti ndiyankhe funso ili: Kodi ng'ombe yopanda mafuta ili ndi gawo mu chakudya cha DASH?

Lero, kafukufuku ameneyu adasindikizidwa. Ndipo titayeza ndi kuyeza chilichonse 36 anthu osiyanasiyana adayika pakamwa pawo pafupifupi miyezi 6, tili ndi yankho lolimba ku funso lathu: Inde. Ng'ombe yotsamira ikhoza kuphatikizidwa mu chakudya cha DASH.

Atakhala pa DASH ndi BOLD (zakudya za DASH zokhala ndi 4.0oz / tsiku la ng'ombe yowonda), ochita nawo kafukufuku adatsika ndi 10 peresenti ya cholesterol yawo ya LDL ("yoyipa"). Tidayang'ananso zakudya zachitatu, zakudya za BOLD+, zomwe zinali zomanga thupi (28 peresenti ya zopatsa mphamvu tsiku lililonse poyerekeza ndi 19 peresenti pazakudya za DASH ndi BOLD). Zakudya za BOLD + zimaphatikizanso 5.4oz wama ng'ombe owonda patsiku. Pambuyo potsatira zakudya za BOLD+ kwa miyezi isanu ndi umodzi, otenga nawo gawo adakumananso ndi kuchepetsedwa kofanana kwa cholesterol ya LDL monga momwe amadyera a DASH ndi BOLD.

Mkhalidwe wokhazikika wa phunziro lathu (tinayeza ndi kuyeza zonse zomwe ophunzira adadya ndipo wophunzira aliyense adadya zakudya zitatuzi) zidatilola kunena kuti ng'ombe yowonda ikhoza kuphatikizidwa muzakudya zopatsa thanzi komanso kuti mutha kusangalala nazo. 4-5.4oz ya ng'ombe yowonda patsiku mukakumanabe ndi malingaliro apano a zakudya zamafuta odzaza.

Mutha kuwerenga kafukufuku wathunthu apa.
