Izondlo ezininzi zibanga ukuba zilungile entliziyweni yakho.

Phakathi kwezona zaziwayo zii-phytosterol, zihlala zongezwa kwiimargarines nakwiimveliso zobisi.

Iziphumo zabo zokunciphisa i-cholesterol ngokubanzi zamkelwe kakuhle.

Nangona kunjalo, uphando lwezenzululwazi lutyhila ezinye iinkxalabo ezinzulu.

Eli nqaku licacisa ukuba zeziphi ii-phytosterol kunye nokuba zingayenzakalisa njani impilo yakho.

Yintoni iiPhytosterol?

Iipytosterol, okanye ii-sterols zezityalo, lusapho lweemolekyuli ezinxulumene necholesterol.

Zifumaneka kwiimbumba zeseli zezityalo, apho zidlala indima ebalulekileyo-njenge-cholesterol ebantwini.

Ezona phytosterol zixhaphakileyo ekutyeni kwakho yi-campesterol, sitosterol, kunye ne-stigmasterol. Izityalo zestanols - enye ikhompawundi eyenzeka ekutyeni kwakho - ziyafana.

Nangona abantu beguqukele ekusebenzeni kunye ne-cholesterol kunye ne-phytosterol kwiinkqubo zabo, umzimba wakho ukhetha i-cholesterol ().

Ngapha koko, unee-enzymes ezimbini ezibizwa ngokuba zii-sterolins ezilawula ukuba ngawaphi ama-sterol anokungena emzimbeni wakho emathunjini.

Zizinto ezincinci kuphela zepytosterol ezidlulayo-xa kuthelekiswa ne-55% ye-cholesterol ().

Iipytosterol zizityalo ezilingana necholesterol kwizilwanyana. Banobume obufanayo beemolekyuli kodwa banemizimba eyahlukileyo.

Umxholo weoyile yemifuno kunye neMargarine

Ukutya okunempilo okuninzi kwezityalo- kubandakanya amandongomane, iimbewu, iziqhamo, imifuno, kunye nembotyi-inezinto ezininzi zeprotosterol.

Kucetyisiwe ukuba abazingeli be-paleolithic-hunter, abatya ukutya okunotyebileyo kwizityalo, batya izixa ezikhulu zeephytosterol ().

Nangona kunjalo, xa kuthelekiswa nokutya kwale mihla, oku akuyonyani ngokupheleleyo.

Ioyile yemifuno iphezulu kakhulu kwii-phytosterol. Kuba ezi oyile zongezwa kukutya okuninzi okusetyenzisiweyo, inani elipheleleyo lokutya ii-phytosterol kusenokwenzeka ukuba likhulu kunangaphambili ().

Ukutya okuziinkozo kukwaqulathe izixa ezilinganiselweyo zeepytosterol kwaye inokuba ngumthombo ophambili wabantu abatya iinkozo ezininzi ().

Ngaphezu koko, ii-phytosterol zongezwa kwiimargarines, ezibizwa ngokuba yi "cholesterol esehlayo" kwaye zibango lokunceda ukuthintela isifo sentliziyo.

Nangona kunjalo, eli bango alithandabuzeki.

Ioyile yemifuno kunye neemargarine ziqulathe isixa esikhulu seephytosterol. Ngenxa yokuba iioyile zemifuno zongezwa kukutya okuninzi okusetyenzisiweyo, uxinzelelo lwee-phytosterol ekutyeni kunokwenzeka ukuba zinkulu kunakuqala.

Ngamana unokuba nefuthe elincinci kwimpilo yentliziyo

Kuyinyani ebhaliweyo yokuba ii-phytosterol zinokuhlisa amanqanaba e-cholesterol.

Ukutya i-2-3 yeeprotosterol ngosuku ngeeveki ezingama-3-4 kunokunciphisa i-cholesterol "embi" ye-LDL nge-10% (,).

Oku kusebenza ngakumbi kubantu abane-cholesterol ephezulu-nokuba bayayithatha okanye abayithathi na imichiza ye-cholesterol yokunciphisa i-cholesterol (,).

I-Phytosterol ikholelwa ukuba isebenza ngokukhuphisana nee-enzymes ezifanayo njenge-cholesterol emathunjini akho, ukukhusela ngokufanelekileyo i-cholesterol ekungeniseni ().

Nangona amanqanaba aphezulu e-cholesterol enxulunyaniswa nomngcipheko owandayo wesifo sentliziyo, kungenzeka ukuba ayisosizathu sesifo sentliziyo.

Ngesi sizathu, akucaci nokuba ukunciphisa amanqanaba e-cholesterol yakho kunesiphumo sengozi yesifo sentliziyo.

Iipytosterol zinokunciphisa amanqanaba e-cholesterol "amabi" e-LDL nge-10%. Nangona kunjalo, oku akunakuphucula impilo yakho yentliziyo.

Ngamana unokunyusa umngcipheko wokuhlaselwa yintliziyo

Abantu abaninzi bacinga ukuba ii-phytosterol zinokuthintela ukuhlaselwa yintliziyo kuba zinciphisa i-cholesterol.

Nangona kunjalo, akukho zifundo zibonisa ukuba ii-phytosterol zinokunciphisa umngcipheko wesifo sentliziyo, ukubetha okanye ukufa.

Ngokudabukisayo, ii-phytosterol zinokunyusa umngcipheko. Izifundo zabantu ezininzi zidibanisa ukutya kakhulu kwe-phytosterol kunye nomngcipheko wesifo sentliziyo (,,).

Ukongeza, phakathi kwabantu abanesifo sentliziyo kwisifundo esikhulu saseScandinavia, abo banee-phytosterol ezininzi babenokufumana olunye uhlaselo lwentliziyo ().

Kwesinye isifundo kumadoda anesifo sentliziyo, abo banomngcipheko ophezulu wokuhlaselwa yintliziyo babenomngcipheko ophindwe kathathu ukuba babenezinga eliphezulu lee-phytosterol egazini ().

Ngaphezu koko, ukufundwa kweempuku kunye neempuku kubonisa ukuba ii-phytosterol zonyusa i-plaque buildup kwimithambo, ibangela ukubetha, kunye nokunciphisa ixesha lokuphila (,).

Nangona uninzi lweziphathamandla zempilo ezinje ngeAmerican Heart Association zisacebisa ii-phytosterol ukuphucula impilo yentliziyo, abanye abavumi.

Umzekelo, iKhomishini yeDrug yaseJamani, iArhente yeMigangatho yokutya yaseFrance (ANSES) kunye neZiko leSizwe lase-UK lezeMpilo kunye noKhathalelo oluPhezulu (i-NICE) bonke bayakuphazamisa ukusetyenziswa kwee-phytosterol zokuthintela isifo sentliziyo (16).

Gcina ukhumbula ukuba imeko enqabileyo yemfuza ebizwa ngokuba yi-phytosterolemia okanye i-sitosterolemia yenza ukuba abanye abantu bathathe inani elikhulu lee-phytosterol kwigazi labo. Oku kwandisa ingozi yesifo senhliziyo ().

Ngelixa ii-phytosterol zikhokelela ekunciphiseni amanqanaba e-cholesterol, uninzi lwezifundo lubonisa ukuba banokwandisa umngcipheko wesifo sentliziyo.

Ngamana unokukhusela umhlaza

Obunye ubungqina bubonisa ukuba ii-phytosterol zinokunciphisa umngcipheko womhlaza.

Izifundo zoluntu zibonisa ukuba abantu abatya ii-phytosterol ezininzi banomngcipheko ophantsi wesisu, umphunga, isifuba kunye nomhlaza we-ovari (,,,).

Izifundo kwizilwanyana zikwabonisa ukuba ii-phytosterol zinokuba neepropathi zomhlaza, zinceda ukunciphisa ukukhula kunye nokusasazeka kwamathumba (,,,).

Nangona kunjalo, kuphela izifundo zabantu ezixhasa oku ziqwalasele ngokwendalo. Olu hlobo lophando aluniki ubungqina benzululwazi.

Ke, kufuneka uphando olungakumbi.

Izifundo zabantu kunye nezilwanyana zibonisa ukuba ukutya kwe-phytosterol kuhambelana nomngcipheko omncinci womhlaza. Nangona kunjalo, uphando olongezelelweyo luyafuneka.

Umgca osezantsi

Kwiminyaka eliwaka, ii-phytosterol ziyinxalenye yokutya kwabantu njengenxalenye yemifuno, iziqhamo, iimbotyi kunye nokunye ukutya kwezityalo.

Nangona kunjalo, ukutya kwangoku ngoku kunexabiso eliphezulu ngokungaqhelekanga-ikakhulu ngenxa yokusetyenziswa kweoyile yemifuno esulungekileyo kunye nokutya okuqinileyo.

Ngelixa ukufunxwa okuphezulu kwee-phytosterol kusithiwa ziphilile entliziyweni, ubungqina bubonisa ukuba banokubangela isifo sentliziyo kunokuthintela.

Nangona kulungile ukutya ii-phytosterol kuzo zonke iintlobo zokutya kwezityalo, kungcono ukunqanda ukutya okunezityebi ze-phytosterol kunye nezongezo.
