Ukugcina amanqanaba e-cholesterol asempilweni kubalulekile kwimpilo yentliziyo nakwimpilo iyonke. Amanqanaba aphezulu e-cholesterol angakhokelela kwiingxaki ezahlukeneyo zempilo, kubandakanya isifo sentliziyo kunye nesifo sohlangothi. Nangona amayeza anokumiselwa ukulawula i-cholesterol, utshintsho olulula lwendlela yokuphila lunokudlala indima ebalulekileyo ekunciphiseni i-cholesterol ngokwendalo. Ukutya ukutya okunempilo, ukwenza umthambo rhoqo, ukulawula uxinzelelo, ukulala ngokwaneleyo, kunye nokujoyina isicwangciso sesongezelelo sokutya konke ngamanyathelo abalulekileyo ekugcineni amanqanaba e-cholesterol asempilweni. Ngokwenza olu hlengahlengiso luncinci kwimisebenzi yakho yemihla ngemihla, unokuphucula impilo yentliziyo yakho kwaye ugcine impilo yakho iyonke.
I-cholesterol yinto efana ne-wax, enamafutha efumaneka ngokwendalo kwiseli nganye yomzimba wethu. Yinto ebalulekileyo efunekayo ukuvelisa iihomoni, i-vitamin D, kunye nezinto ezinceda ekugayweni kokutya. Nangona i-cholesterol iyimfuneko ukuze imizimba yethu isebenze kakuhle, amanqanaba aphezulu e-cholesterol anokuba yingozi kwimpilo yethu.
Imizimba yethu ivelisa i-cholesterol esibindini nasemathunjini, kwaye sikwasebenzisa i-cholesterol ngokutya okuthile, okufana nenyama, inkukhu, kunye neemveliso zobisi ezinamafutha apheleleyo. Kukho iintlobo ezimbini ze-cholesterol: i-high-density lipoprotein (HDL) cholesterol, edla ngokubizwa ngokuba yi-"good" cholesterol, kunye ne-low-density lipoprotein (LDL) cholesterol, edla ngokubizwa ngokuba yi-"bad" cholesterol.
I-cholesterol ye-HDL ithathwa njenge "ilungileyo" kuba inceda ukususa i-cholesterol ye-LDL engaphezulu egazini kwaye iyithuthe ibuyele esibindini, apho inokwaphulwa khona kwaye ikhutshwe emzimbeni. I-cholesterol ye-LDL, kwelinye icala, inokwakheka kwimithambo yegazi, yenze i-plaque, ivale imithambo yegazi kwaye inciphise ukuhamba kwegazi. Oku kwandisa umngcipheko wesifo sentliziyo, istroke, kunye nezinye iingxaki zentliziyo.
Amanqanaba aphezulu e-cholesterol egazini ayinto ebangela umngcipheko omkhulu wesifo sentliziyo, imbangela ephambili yokufa kwihlabathi liphela. Izinto ezininzi zinokubangela i-cholesterol ephezulu, kubandakanya ukutya okungenampilo, ukungabikho komsebenzi womzimba, ukutshaya, ukutyeba kakhulu, kunye nezinye iimeko zonyango, ezifana nesifo seswekile kunye ne-hypothyroidism.
Ukuze kuqinisekiswe amanqanaba akho e-cholesterol, uvavanyo lwegazi olubizwa ngokuba yi-lipid profile okanye i-lipid panel ludla ngokwenziwa. Olu vavanyo lulinganisa i-cholesterol yakho iyonke, i-LDL cholesterol, i-HDL cholesterol, kunye ne-triglycerides (olunye uhlobo lwamafutha egazini lakho).
Kukho iintlobo ezimbini eziphambili ze-cholesterol: i-LDL kunye ne-HDL
I-LDL cholesterol: I-LDL cholesterol imele i-low-density lipoprotein kwaye yaziwa ngokuba yi-"bad" cholesterol. Oku kungenxa yokuba inokukhokelela ekwakhiweni kwe-plaque, indibaniselwano yamafutha, i-cholesterol kunye ne-calcium enokuvala imithambo yegazi kwaye ithintele ukuhamba kwegazi. Xa ukuhamba kwegazi kuvaliwe, unokuba nesifo sentliziyo okanye isifo sohlangothi.
I-cholesterol ye-HDL: I-cholesterol ye-HDL imele i-high-density lipoprotein. Ibizwa ngokuba yi-cholesterol "elungileyo" kuba i-HDL ikhusela intliziyo. Umsebenzi we-HDL kukuthutha inxalenye ye-cholesterol ye-LDL esuka entliziyweni ukuya esibindini, apho inokukhutshwa khona emzimbeni.
1. Izinto ezibangela ukutya
Ukutya kwethu kudlala indima ebalulekileyo ekumiseleni amanqanaba e-cholesterol. Ukutya okunamafutha agcweleyo kunye namafutha e-trans kunokukhokelela ekwandeni kwe-cholesterol ye-low-density lipoprotein (LDL), edla ngokubizwa ngokuba yi-cholesterol "embi". Ukutya inyama ebomvu egqithisileyo, iimveliso zobisi ezinamafutha amaninzi, ukutya okuqhotsiweyo, ukutya okulula okucutshungulwayo, kunye neepastries kunokukhokelela ekwandeni kwe-cholesterol ye-LDL, enokuvala imithambo yegazi kwaye ithintele ukuhamba kwegazi.
2. Indlela yokuphila yokungaphumli
Ukungazilolongi umzimba yenye into ebalulekileyo kumanqanaba aphezulu e-cholesterol. Ukuzilolonga rhoqo kunceda ukonyusa i-cholesterol ye-high-density lipoprotein (HDL), edla ngokubizwa ngokuba yi-cholesterol "elungileyo", edlala indima ebalulekileyo ekuthuthweni kwe-cholesterol egqithisileyo ukusuka egazini ukuya esibindini ukuze isetyenzwe. Ngaphandle kokusebenza ngokwaneleyo komzimba, ibhalansi phakathi kwe-LDL kunye ne-HDL cholesterol inokuphazamiseka, nto leyo ebangela ukuba amanqanaba e-cholesterol anyuke.
3. Ukutyeba kakhulu kunye nokunyuka kobunzima
Ukutyeba kakhulu okanye ukutyeba kakhulu kunxulumene kakhulu namanqanaba aphezulu e-cholesterol. Ukutyeba kakhulu, ingakumbi ecaleni kwesisu, kunyusa amanqanaba e-LDL cholesterol kunye ne-triglyceride ngelixa kunciphisa i-HDL cholesterol. Ukutyeba kakhulu kuchaphazela amandla omzimba okucola nokususa i-cholesterol ngokufanelekileyo egazini, nto leyo ekhokelela ekuqokeleleni kwe-cholesterol kunye nophuhliso lwe-atherosclerosis.
4. Izinto ezibangela ufuzo
Abanye abantu banomkhwa wokuba namanqanaba aphezulu e-cholesterol ngenxa yeengxaki zemfuza ezifana ne-familial hypercholesterolemia. Ezi meko ziphazamisa amandla omzimba okususa i-LDL cholesterol engaphezulu egazini, nto leyo ebangela amanqanaba aphezulu e-cholesterol rhoqo. Izinto zemfuza zibangela ipesenti encinci kuphela yamatyala e-cholesterol ephezulu, kodwa akufuneki zityeshelwe xa kuvavanywa izinto ezinobungozi zomntu.
5. Ukutshaya nokusela
Ukutshaya nokusela utywala kakhulu kunokuchaphazela kakubi amanqanaba e-cholesterol. Ukutshaya kunciphisa i-cholesterol ye-HDL, okwenza kungasebenzi kakuhle ekususeni i-cholesterol ye-LDL egazini. Kuyonakalisa nolwelo lwemithambo yakho, okwenza kube lula ukuba i-cholesterol ingene kwaye yenze i-plaque. Kwelinye icala, ukusela kakhulu kunokunyusa amanqanaba e-triglycerides, uhlobo lwamafutha egazini olunxulunyaniswa ne-cholesterol ephezulu.
1. Intlungu yesifuba okanye i-angina: Enye yeempawu ezibalulekileyo ze-cholesterol ephezulu ziintlungu zesifuba okanye i-angina. Xa i-plaque iqokelelana kwimithambo yegazi, inokuthintela ukuhamba kwegazi ukuya kwimisipha yentliziyo, ibangele iintlungu zesifuba okanye ukungakhululeki. Le ntlungu inokuphumela kwiingalo, emagxeni, entanyeni, emhlathini, okanye emqolo kwaye idla ngokubangelwa kukusebenza ngokomzimba okanye uxinzelelo lweemvakalelo. Ukuba ufumana iimpawu ezinjalo, kufuneka ufune unyango ngokukhawuleza.
2. Ukudinwa kakhulu kunye nobuthathaka: Ukuziva udiniwe rhoqo okanye ubuthathaka ngaphandle kwesizathu esicacileyo kunokuba luphawu olungabonakaliyo lwe-cholesterol ephezulu. Xa imithambo yegazi ivalekile ngenxa yokwakheka kwe-plaque, inokuthintela ukuhamba kwegazi emzimbeni, okubangela ukudinwa kunye nobuthathaka. Ezi mpawu zihlala zingaqatshelwa okanye zibangelwe yindlela yokuphila exakekileyo okanye ukungalali ngokwaneleyo. Nangona kunjalo, kubalulekile ukunikel’ ingqalelo kwezi mpawu, njengoko zinokubonisa iingxaki zempilo ezisisiseko, kubandakanya ne-cholesterol ephezulu.
3. Ukuphefumla Okunzima: Ukuba uhlala uzifumana uphelelwa ngumphefumlo, nokuba usebenza kancinci okanye uphumle, oko kunokubangela inkxalabo. Ukwakheka kweplaque kwimithambo yegazi kunokuchaphazela ukujikeleza kwegazi emiphungeni, okwenza kube nzima ukuphefumla. Olu phawu ngamanye amaxesha lukhokelela ekuxilongweni okungafanelekanga njengengxaki yokuphefumla endaweni yokuba lunxulumene ne-cholesterol ephezulu.
4. Uxinzelelo lwegazi oluphezulu: Uxinzelelo lwegazi oluphezulu, okanye uxinzelelo lwegazi oluphezulu, ludla ngokunxulunyaniswa namanqanaba aphezulu e-cholesterol. Ukuqokelelwa kweplaque kwimithambo yegazi akugcini nje ngokuthintela ukuhamba kwegazi, kodwa kukwabeka uxinzelelo olongezelelekileyo entliziyweni, okubangela ukuba uxinzelelo lwegazi lunyuke. Nangona uxinzelelo lwegazi oluphezulu lunokuba nezizathu ezininzi, kufuneka kuqwalaselwe ukuba kukho i-cholesterol ephezulu njengesizathu esingundoqo.
5. Kwiimeko ezingaqhelekanga, abantu abane-cholesterol ephezulu banokuba nee-cholesterol ezithambileyo nezimthubi ezibizwa ngokuba zii-xanthomas eluswini lwabo. Ezi deposits zibonakala ikakhulu kwiinkophe nakwiindawo ezijikeleze ii-eyelids njengeziqwenga ezithe tyaba nezimthubi. Nangona zingenabuhlungu, ubukho bazo bufanele buqaphele abantu malunga nokuba kukho amanqanaba aphezulu e-cholesterol.
Ukugcina amanqanaba e-cholesterol asempilweni kubalulekile kwimpilo iyonke, njengoko amanqanaba aphezulu e-cholesterol angakhokelela kumngcipheko okhulayo wesifo sentliziyo kunye nezinye iingxaki zentliziyo. Nangona ukuthatha indlela yokuphila enempilo, kubandakanya ukuzilolonga rhoqo kunye nokutya okunesondlo, kusisiseko sokulawula i-cholesterol, ezinye izongezo zokutya nazo zinokubonelela ngokunyusa okukhulu.
1. Ii-asidi zamafutha ze-Omega-3
Ii-omega-3 fatty acids, ezifumaneka rhoqo kwiintlanzi ezinamafutha ezifana nesalmon, mackerel, kunye nesardines, zaziwa ngeenzuzo zazo ezininzi zempilo. Ukufaka ezi fatty acids ekutyeni kwakho ngokusebenzisa izongezo okanye ukutya iintlanzi kunokunceda ukunciphisa amanqanaba e-triglyceride kunye nokunyusa amanqanaba e-cholesterol ye-HDL (elungileyo). Ii-omega-3 fatty acids zikwanazo neempawu zokulwa nokuvuvukala ezinceda ukuthintela ukwakheka kwe-plaque kwimithambo yegazi, nto leyo enceda ngakumbi ekuphuculeni impilo yentliziyo.
2. Igalikhi
Igalikhi kudala yaziwa ngeenzuzo zayo ezininzi zempilo, kuquka amandla ayo okunciphisa amanqanaba e-cholesterol. I-Allicin, into esebenzayo kwigalikhi, ibonakalisiwe ukuba inciphisa ukuveliswa kwe-cholesterol esibindini kwaye ithintele ukubola kwe-LDL cholesterol. Ukongeza igalikhi eluhlaza okanye ephekiweyo ekutyeni kwakho okanye ukuthatha isongezelelo segalikhi kunokuphucula iprofayili yakho ye-cholesterol, okwenza kube lula kwaye kube yindleko kwisicwangciso sakho sokulawula i-cholesterol.
I-OEA yimolekyuli yendalo emzimbeni wethu esebenza njengemolekyuli yokubonisa iinkqubo ezahlukeneyo ze-physiological. Idlala indima ebalulekileyo ekulawuleni ulungelelwaniso lwamandla, ukutya, kunye ne-lipid metabolism. I-OEA iveliswa ikakhulu emathunjini ethu amancinci, kodwa inokufumaneka nakwezinye izitho kunye nezicubu.
I-OEA inokulawula amandla e-metabolism ye-cholesterol. Izifundo ezininzi zibonise ukuba i-OEA inokuchaphazela amanqanaba e-cholesterol ngokuchaphazela ukwenziwa kwayo, ukuthuthwa kwayo, kunye nokufunxwa kwayo emzimbeni. Izifundo kwiimodeli zezilwanyana zibonise ukuba ukusetyenziswa kwe-OEA kunciphisa amanqanaba e-cholesterol, ngakumbi i-LDL (low-density lipoprotein) cholesterol, i-cholesterol "embi".
I-OEA yenza oku ngokusebenzisa ii-receptor ezithile zenyukliya emathunjini, kuquka i-PPAR-alpha (i-peroxisome proliferator-activated receptor alpha). Xa i-PPAR-alpha isebenza, ivuselela ukuqhekeka kwamafutha e-fatty acids, ngaloo ndlela inciphisa ukuveliswa kwe-cholesterol, ingakumbi kwisibindi. Ukongeza, i-OEA inokuphucula ukukhutshwa kwe-cholesterol emzimbeni, isebenzise ngakumbi isiphumo sayo sokunciphisa i-cholesterol.
Ukongeza, i-OEA iphucula uvakalelo lwe-insulin kwaye ilawula imetabolism yeswekile, zombini ezi zinto zibalulekileyo ekugcineni amanqanaba e-cholesterol asempilweni. Ngokulawula ezi nkqubo zemetabolism, i-OEA ngokungathanga ngqo ikhuthaza iprofayili ye-lipid esempilweni kwaye inciphisa umngcipheko weengxaki ezinxulumene ne-cholesterol.
I-cholesterol yinto enamafutha eveliswa yimizimba yethu ngokwendalo kwaye ikwafumaneka ekutyeni okuthile. Idlala indima ebalulekileyo kwimisebenzi yomzimba efana nokuveliswa kweehomoni kunye nee-membranes zeeseli.
Uphando lubonisa ukuba i-PEA inokuthintela ukuveliswa kwe-cholesterol kwiiseli zesibindi. Ngokwenza njalo, inokunceda ukwehlisa amanqanaba e-cholesterol iyonke kwaye inciphise umngcipheko wesifo sentliziyo. Isiphumo esinokubakho sokunciphisa i-cholesterol se-PEA kucingelwa ukuba sibangelwa kukukwazi kwayo ukwenza ii-receptor ezithile ezilawula imetabolism ye-cholesterol.
Ukongeza, i-PEA ifunyenwe ineempawu zokulwa nokuvuvukala. Ukudumba kudlala indima ebalulekileyo ekuphuhlisweni kwe-atherosclerosis, isifo apho i-cholesterol plaque iqokelelana kwimithambo yegazi, nto leyo ebangela ukuncipha kokuhamba kwegazi kunye nokwandisa umngcipheko wesifo sentliziyo. Ngokunciphisa ukudumba, i-PEA inokunceda ukugcina imithambo yegazi isempilweni kwaye ithintele ukwakheka kwe-cholesterol.
Umbuzo: Ngaba amayeza endalo okanye izongezo ziyayinciphisa ngempumelelo i-cholesterol?
A: Amanye amayeza endalo kunye nezongezo zinokuba nemiphumo enokubangela ukwehla kwe-cholesterol, kodwa ukusebenza kwawo kuyahluka. Kucetyiswa ukuba udibane nogqirha wezempilo ngaphambi kokuba uqalise naluphi na unyango lwendalo okanye izongezo ukuqinisekisa ukhuseleko nokusebenza kwazo.
