Cholesterol Zakudya ndi Kuopsa Kwa Mtima
Takhala tikumva kwa zaka makumi ambiri kuti magazi ambiri amatha kupatsirana ndi matenda a athelesclerosis. Takhala tikumva kwa zaka zambiri kuti, pofuna kuti tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda, tipewe zakudya zamatenda apamwamba m'madyerero athu. (Mwachindunji, tawuzidwa kuti kudya mazira ambiri ndi olakwika kwa ife.)
Koma mu February 2015 Achimereka anamva nkhani yochititsa chidwi yomwe Komiti Yowunikira Otsogolera Zogwirizana ndi Dietary ya boma inavomereza kuthetsa malingaliro ake aatali kuti tipewe zakudya zomwe zili ndi cholesterol. Mazira (ndi shrimp ndi lobster), izo zikuwonekera tsopano, ndi zakudya zathanzi kachiwiri!
Kodi Chimake Chikupitilira Chiyani?
Nkhaniyi sizinadodometse kwa aliyense yemwe wakhala akutsata mabuku azachipatala m'zaka zaposachedwa (kapena ndithu, kwa zaka makumi angapo zapitazi). Chifukwa chake, izi siziyenera kukhala zofunikira kwa madotolo ambiri, makamaka akatswiri a cardiologists, omwe ayenera kumvetsa za cholesterol.
Palibe umboni wokhudzana ndi kachipatala wochokera ku maphunziro ophunzitsidwa bwino umene cholesterol cha zakudya chimakula kwambiri. Machenjezo ochenjeza onena za kudya cholesterolin akhala akudalira makamaka pa zovuta zapadera.
Kenako, mu 2013, kufufuza kwakukulu kwa meta kunasindikizidwa mu British Medical Journal yomwe inkayang'ana maphunziro asanu ndi atatu a zachipatala omwe amafufuza cholesterol ndi zakudya.
Mwa anthu pafupifupi hafu miliyoni omwe analembetsa, panalibe mgwirizano pakati pa dzira lowagwiritsa ntchito komanso chiopsezo cha matenda a mitsempha yam'mimba kapena kupwetekedwa . (Ngati zilizonse, chikhalidwecho chinali kumbali inayo; ku gulu lotetezera ndi dzira-kudya.) Phunziroli silingakhale mawu otsiriza pa nkhaniyo, koma ndi umboni wabwino kwambiri womwe tiyenera kukhala nawo pachibwenzi, Titha kukhala ndi nthawi yaitali.
Ndimeta-makayi, omwe amakhulupirira kwambiri, potsirizira pake anasunthira komiti ya zakudya ya boma kuti idzasinthe malingaliro ake.
Zambirizi Zimagwirizana ndi Zimene Timadziwa Zokhudza Cholesterol Metabolism
Tadziwa zaka zambiri kuti chiwopsezo cha mtima chimagwirizanitsidwa ndi makina a cholesterol a LDL . Zingadabwe kuti mukudziwa (ndipo, mantha amodzi, akhoza kudabwitsa madokotala ambiri kuti adziwe) kuti cholesterol cha zakudya sichimayambitsa cholesterol cha LDL.
Mukadya chakudya chokwanira cholesterol, cholesterol yomwe imalowa m'matumbo imaphatikizidwa mu chylomicrons (osati mu LDL particles), pamodzi ndi mafuta acids kuchokera ku chakudya chanu.
Mitunduyi imatulutsidwa m'magazi, ndipo amapereka mafuta omwe mwangodya kumene kumatenda (minofu ndi mafuta). Mitsempha yotchedwa chylomicron - yomwe ikuphatikizapo zakudya zonse zopatsa mafuta m'thupi - zimatengedwa kupita kuchiwindi kuti zigwiritsidwe. Cholesterol kuchokera ku zakudya zanu, ndiye, sichimasulidwa mwachindunji ku makoswe ndipo saloledwa mwachindunji ku LDL particles.
Kawirikawiri, ma chylomicrons amachotsedweratu m'magazi mkati mwa ola limodzi kapena awiri mutatha kudya. Ichi ndi chifukwa chimodzi chomwe mukuyenera kuti mukusala kudya pamene muli ndi chiwerengero cha mankhwala a magazi - palibe amene ali ndi chidwi choyeza cholesterol mu makylomicron chifukwa chylomicron-cholesterol sichikukhudzana ndi chiopsezo cha mtima.
Cholesterol ya zakudya ikhoza kukhala ndi mphamvu pa mitsempha ya cholesterol ya LDL, koma mwachindunji. Ndi ntchito ya chiwindi kuti apange kuchuluka kwa cholesterol pogwiritsa ntchito zosowa za thupi. (Cholesterol yogwiritsidwa ntchito ndi chiwindi imatumizidwa ku lipoproteins ndipo imasulidwa m'magazi kumene kumadzakhala LDL cholesterol.) Choncho, ngati mudya cholesterol ambiri, chiwindi chiyenera kuchepetsa kaphatikizidwe wa kolesterol - Cholesterol LDL - kubwezera.
Pofuna kubwereza, cholesterol cha zakudya sichidziwika mwachindunji kumatendawa ndipo sichidziwika mwachindunji ku LDL particles.
Chiwindi - chiwalo chachikulu cholamulira - chimayikidwa pakati pa cholesterol ndi zakudya za LDL cholesterol, ndipo imodzi mwa ntchito zake ndi kusintha kusintha kwa cholesterol mmalo mwa zakudya zanu, kuti musunge LDL cholesterol m'magulu osiyanasiyana.
Choncho, sitiyenera kudabwa kwa madokotala amene amatsatira mabuku a zachipatala, komanso omwe amamvetsa kagayidwe kabakiteriya, kuti aphunzire kuti cholesterol chodyera sichinthu chachikulu chomwe chimapangitsa kuti munthu adwale matenda a mtima.
