Zakudya za ku Mediterranean - asayansi apenda zakudya zotchukazi pamlingo wa ma cell ndipo adapeza kuti zigawo zake zenizeni ndipo mwinamwake chakudya chonse chikhoza kuonjezera nthawi ya moyo mpaka 35 peresenti.
Kutalikitsa kolimbikitsa kwa nthawi ya moyo kunawonetsedwa pogwiritsa ntchito zamoyo za labotale - nyongolotsi. Koma zotsatira zake zimakhalaponso mwa anthu, ofufuza amatsutsa.
Zakudya za ku Mediterranean zakhala zikudziwika kwambiri kupitirira dera lomwe limatchulidwa, chifukwa umboni wochuluka ukuwonekera kulimbitsa mbiri yake monga ndondomeko ya zakudya zomwe zimalimbikitsa moyo wautali komanso thanzi labwino.
Kafukufuku wasonyeza kuti anthu amene amatsatira mfundo za zakudya za ku Mediterranean, zomwe zimaphatikizapo kudya zakudya zambiri zochokera ku zomera, nsomba, komanso kuchepetsa kudya nyama yofiira ndi mkaka, nthawi zambiri amakhala athanzi m’mbali zambiri ndipo amadzitama kuti ali ndi moyo wabwino poyerekezera ndi anthu amene ali ndi moyo wautali. amene satsatira mfundo zimenezi. Thanzi lawo lonse limawunikidwa potengera kuchuluka kwa chiwopsezo cha zinthu monga matenda amtima, khansa, shuga, dementia, komanso moyo wapakati.
Komabe, njira zenizeni zomwe zakudya za ku Mediterranean zimatulutsa zotsatirazi sizikudziwika bwino. Ngakhale pali umboni wochuluka wotsimikizira ubwino wake wathanzi, njira zenizeni zomwe kuphatikizika kwapadera kwa zigawo za chakudya kungatalikitse moyo wa munthu sikudziwika.
Kafukufuku wotsogozedwa ndi ofufuza a ku yunivesite ya Stanford adafuna kupereka mayankho pofufuza zotsatira za zakudya zaku Mediterranean pautali wa moyo pama cell. Kafukufukuyu adayang'ana kwambiri za zotsatira za chinthu chimodzi, gwero la mafuta abwino, pa moyo wa nematodes (roundworms).
Kumvetsetsa njira imeneyi ndi kupambana kwakukulu, malinga ndi ochita kafukufuku. Ikhoza kupereka chidziwitso pa zotsatira za mitundu yosiyanasiyana ya mafuta pa thanzi ndikuthandizira kumvetsetsa chifukwa chake zizoloŵezi za zakudya zingathandize kuti moyo ukhale wautali.
“Kaŵirikaŵiri mafuta amati amawononga thanzi. Koma kafukufuku wina wasonyeza kuti mitundu yeniyeni ya mafuta, kapena lipids, ingakhale yopindulitsa,” anatero katswiri wa zachibadwa Anne Brunet wa ku yunivesite ya Stanford.
Zakudya za ku Mediterranean, monga momwe zimafotokozera malangizo ake, zimakhala ndi mafuta ambiri opindulitsa omwe amadziwika kuti monounsaturated fatty acids. Zinthuzi zimapezeka muzinthu monga mtedza, nsomba, ndi mafuta a azitona.
Mmodzi mwamafuta athanzi, oleic acid, adakhala gawo lalikulu la kafukufuku womwe tatchulawa pomwe ofufuza adafuna kupeza kulumikizana ndi moyo wokhala ndi moyo muzamoyo za labotale. Ndizofunikira kudziwa kuti oleic acid ndiye mafuta ambiri a monounsaturated omwe amapezeka mumafuta a azitona ndi mitundu ina ya mtedza.
Kupyolera mu kuwona kwawo kwa zotsatira za roundworm Caenorhabditis elegans, gululo linapeza zabwino ziwiri za oleic acid: choyamba, zimateteza maselo ku kuwonongeka kwa lipid oxidation, ndipo kachiwiri, kumawonjezera milingo ya zigawo ziwiri zazikulu zama cell zomwe zimatchedwa organelles.
Izi zidakhala zazikulu: nyongolotsi zodyetsedwa ndi oleic acid zimakhala nthawi yayitali pafupifupi 35 peresenti kuposa zomwe zimadyetsedwa ndi zakudya zachikhalidwe.
Mtundu umodzi wa organelle, madontho a lipid, omwe amakhala ngati nkhokwe zamafuta, adatenga gawo lofunikira pakuwerengera masiku omwe nyongolotsi ingapulumuke, komanso zokhudzana ndi nthawi yomwe amakhala ndi moyo.
Madontho a Lipid amatenga nawo gawo mu kagayidwe kachakudya pothandizira kuwongolera kagwiritsidwe ntchito ka mafuta, kuwasandutsa mphamvu zama cell.
Akatswiri a sayansi ya zakuthambo adalongosola kuti kuchuluka kwa madontho a lipid mu mphutsi zina kumatha kukhala chizindikiro cha moyo wawo wotsalira. Nyongolotsi zokhala ndi madontho ambiri a lipid zimakhala ndi moyo wautali poyerekeza ndi zomwe zili ndi madontho ochepa.
Ofufuzawo adadyetsa mphutsi zozungulira mwina oleic acid kapena elaidic acid, monounsaturated trans-fatty acid yomwe imapezeka mu margarine ndi chakudya chokonzedwa. Ngakhale kuti ali ndi mawonekedwe ofanana a maselo, ma asidi awiriwa ali ndi zotsatira zosiyana pa thanzi.
Mafuta a Trans, monga elaidic acid, amaonedwa kuti ndi opanda thanzi kapena "oipa" mafuta chifukwa amawonjezera chiopsezo cha matenda a mtima, dementia, ndi mavuto ena a thanzi, zomwe zimapangitsa kuti moyo ukhale wochepa.
Zinatsimikiziridwa kuti nyongolotsi zomwe zimadyetsedwa ndi oleic acid zimawonetsa kuwonjezereka pamaso pa madontho a lipid mkati mwa maselo am'mimba, ndipo izi zimalumikizidwa mwachindunji ndi kutalika kwa moyo wawo.
Komano, mphutsi kudyetsedwa ndi elaidic asidi sanawone kuwonjezeka kwa madontho a lipid ndipo sikutalikitsa moyo wawo.
Asayansi atatsekereza jini yomwe imayambitsa kupanga mapuloteni omwe amapangidwa ndi lipid droplet mu mphutsi zozungulira, zotsatira za kuchuluka kwa moyo zidasowa.
Madontho onse a lipid ndi ma peroxisomes anali ochulukirapo mu nyongolotsi zazing'ono, ndipo milingo yawo idatsika ndi zaka, malinga ndi ofufuza.
Kuchuluka kwa madontho a lipid ndi ma peroxisomes kumasiyanasiyana kutengera mawonekedwe achilengedwe, koma mphutsi zomwe mwachibadwa zinali ndi organelles zambiri zimakhala ndi moyo wautali, wofanana ndi zotsatira za oleic acid.
Oleic acid samakhudza ma organelles okha komanso amateteza maselo poletsa lipid oxidation, zomwe zimawononga ma cell. Mosiyana ndi izi, zotsatira za elaidic acid ndizosiyana, chifukwa zimalimbikitsa okosijeni ndikusokoneza umphumphu wa maselo zomwe zimapangitsa kuti moyo ukhale wotsika.
Uku ndiko kugwirizana pakati pa zakudya ndi moyo wautali, malinga ndi ofufuza omwe anayesa kufotokoza mwatsatanetsatane chifukwa chake komanso momwe zigawo za zakudya za ku Mediterranean zingatalikitsire moyo.
Zotsatira zomwe ofufuza apeza zitha kukhala zothandiza pakuwongolera malangizo azakudya. Athanso kupereka chidziwitso cha momwe angathanirane bwino ndi ukalamba potengera chitetezo ku oxidation yoperekedwa ndi oleic acid.
Komabe, ofufuzawo amavomereza kuti zomwe zapezedwazi ziyenera kuwonedwa ngati zodziwikiratu zomwe zimafunikira maphunziro owonjezera kuti adziwe ngati zotsatira zofananira zitha kupezedwa poyang'ana anthu kuti akhale ndi moyo wabwino.
