Izakhi zomzimba eziningi kuthiwa zilungele inhliziyo yakho.

Phakathi kwama-phytosterol aziwa kakhulu, avame ukufakwa kuma-margarine nemikhiqizo yobisi.

Imiphumela yabo yokwehlisa i-cholesterol ngokuvamile yamukelwa kahle.

Kodwa-ke, ucwaningo lwesayensi lwembula ukukhathazeka okuthile okukhulu.

Lo mbhalo uchaza ukuthi yini ama-phytosterol nokuthi angayilimaza kanjani impilo yakho.

Yini ama-Phytosterol?

Ama-phytosterol, noma ama-sterols ezitshalo, angumndeni wama-molecule ahlobene ne-cholesterol.

Atholakala ezingxenyeni zeseli zezitshalo, lapho adlala khona indima ebalulekile - njenge-cholesterol ebantwini.

Ama-phytosterol ajwayelekile ekudleni kwakho yi-campesterol, sitosterol, ne-stigmasterol. Ama-stanol okutshala - enye into eyenzeka ekudleni kwakho - ayafana.

Yize abantu beguqukele ekusebenzeni nge-cholesterol ne-phytosterol ezinhlelweni zabo, umzimba wakho ukhetha i-cholesterol ().

Eqinisweni, unama-enzyme amabili abizwa ngama-sterolins alawula ukuthi imaphi ama-sterol angangena emzimbeni wakho avela emathunjini.

Amanani amancane kuphela ama-phytosterol adlula lapho - kuqhathaniswa nangu-55% we-cholesterol ().

Ama-phytosterol yizilinganiso ezilinganayo zezitshalo ze-cholesterol ezilwaneni. Zinesakhiwo esifanayo samangqamuzana kodwa zenziwe umzimba ngendlela ehlukile.

Okuqukethwe Kwamafutha Yemifino Namajarini

Ukudla okuningi kwezitshalo okunempilo - kufaka phakathi amantongomane, imbewu, izithelo, imifino, nemidumba - kuqukethe inani elikhulu lama-phytosterol.

Kuphakanyisiwe ukuthi abazingeli be-paleolithic-hunters, abadla ukudla okunothile ezitshalweni, badle inani elikhulu lama-phytosterol ().

Kodwa-ke, uma kuqhathaniswa nokudla kwanamuhla, lokhu akulona iqiniso ngokuphelele.

Amafutha emifino aphezulu kakhulu kuma-phytosterol. Ngoba lawa mafutha afakwa ekudleni okuningi okusetshenzisiwe, inani lokudla eliphelele lama-phytosterol cishe likhulu kunanini ngaphambili ().

Izinhlamvu zokusanhlamvu nazo ziqukethe amanani alinganiselwe ama-phytosterol futhi angaba umthombo omkhulu wabantu abadla okusanhlamvu okuningi ().

Ngaphezu kwalokho, ama-phytosterol afakwa kuma-margarine, abizwa ngokuthi "ukwehlisa i-cholesterol" futhi athi asiza ukuvimbela isifo senhliziyo.

Kodwa-ke, lokhu kugomela kuyangabazeka.

Amafutha emifino kanye namajarini aqukethe inani eliphakeme lama-phytosterol. Ngenxa yokuthi uwoyela wemifino ungezwa ekudleni okuningi okusetshenzisiwe, ukuhlushwa kwama-phytosterol ekudleni kungenzeka kukhulu kunanini ngaphambili.

Kungaba Nomthelela Omncane Empilweni Yenhliziyo

Kuliqiniso elibhalwe phansi ukuthi ama-phytosterol angehlisa amazinga e-cholesterol.

Ukudla amagremu ama-2-3 wama-phytosterol ngosuku ngamaviki angu-3-4 kunganciphisa i-cholesterol "embi" ye-LDL cishe ngo-10% (,).

Lokhu kusebenza ikakhulukazi kubantu abane-cholesterol ephezulu - noma ngabe bathatha izidakamizwa ezinciphisa ukwehla kwe-cholesterol (,).

I-Phytosterol kukholakala ukuthi isebenza ngokuncintisana nama-enzyme afanayo ne-cholesterol esiswini sakho, ivimbela ngempumelelo i-cholesterol ukuthi ingangeni ().

Yize amazinga aphezulu e-cholesterol ehlotshaniswa nengozi eyengeziwe yesifo senhliziyo, kungenzeka ukuthi ayisiyona imbangela yesifo senhliziyo.

Ngalesi sizathu, akucaci ukuthi ukunciphisa amazinga akho e-cholesterol kunomthelela yini engozini yesifo senhliziyo.

Ama-phytosterol anganciphisa amazinga “amabi” e-LDL cholesterol cishe ngo-10%. Kodwa-ke, lokhu kungenzeka kungayithuthukisi impilo yenhliziyo yakho.

Kwangathi Kungeze Ingozi Yakho Yokuhlaselwa Yinhliziyo

Abantu abaningi bacabanga ukuthi ama-phytosterol angavimbela ukuhlaselwa yinhliziyo ngoba yehlisa i-cholesterol.

Kodwa-ke, alukho ucwaningo olubonisa ukuthi ama-phytosterol anganciphisa ingozi yesifo senhliziyo, isifo sohlangothi noma ukufa.

Ngokudabukisayo, ama-phytosterol angakhuphula ubungozi bakho. Izifundo eziningi zabantu zixhuma ukudla okuphezulu kwe-phytosterol nengozi eyengeziwe yesifo senhliziyo (,,).

Ngokwengeziwe, phakathi kwabantu abanesifo senhliziyo ocwaningweni olukhulu lwaseScandinavia, labo abanama-phytosterol amaningi babesengozini yokuhlaselwa yisifo senhliziyo ().

Kokunye ukuhlola kwabesilisa abanesifo senhliziyo, labo abanengozi enkulu yokuhlaselwa yisifo senhliziyo babesengozini enkulu ephindwe kathathu uma benamanani amaningi ama-phytosterol egazini ().

Ngaphezu kwalokho, ucwaningo olwenziwa kumagundane namagundane lukhombisa ukuthi ama-phytosterol akhulisa uqweqwe olwakhiwe emithanjeni yegazi, abangele imivimbo, futhi anciphise isikhathi sokuphila (,).

Noma iziphathimandla eziningi zezempilo ezifana ne-American Heart Association zisancoma ama-phytosterol ukuthuthukisa impilo yenhliziyo, abanye abavumelani nalokhu.

Isibonelo, i-Drug Commission yaseJalimane, i-Food Standards Agency yaseFrance (i-ANSES) kanye ne-UK's National Institute for Health and Care Excellence (NICE) konke kudikibalisa ukusetshenziswa kwama-phytosterol okuvikela izifo zenhliziyo (, 16).

Khumbula ukuthi isimo sezakhi zofuzo esingajwayelekile esibizwa nge-phytosterolemia noma i-sitosterolemia senza abanye abantu bamunce inani elikhulu lama-phytosterol egazini labo. Lokhu kwandisa ingozi yesifo senhliziyo ().

Ngenkathi ama-phytosterol aholela ekunciphiseni amazinga e-cholesterol, izifundo eziningi ziphakamisa ukuthi zingandisa ingozi yesifo senhliziyo.

Kwangathi Kuvikelwe Umdlavuza

Obunye ubufakazi busikisela ukuthi ama-phytosterol anganciphisa ingozi yomdlavuza.

Ucwaningo lwabantu lubonisa ukuthi abantu abadla ama-phytosterol amaningi banobungozi obuncane besisu, amaphaphu, isifuba nomdlavuza we-ovari (,,,).

Ucwaningo ezilwaneni lukhombisa nokuthi ama-phytosterol angaba nezakhi ze-anticancer, okusiza ukunciphisa ukukhula nokusabalala kwezimila (,,,).

Kodwa-ke, okuwukuphela kwezifundo zabantu ezisekela lokhu kungukubheka ngokwemvelo. Lolu hlobo locwaningo alunikeli ngobufakazi besayensi.

Ngakho-ke, kudingeka olunye ucwaningo.

Izifundo zabantu nezilwane ziphakamisa ukuthi ukudla kwe-phytosterol kuhlotshaniswa nengozi encishisiwe yomdlavuza. Kodwa-ke, kudingeka olunye ucwaningo.

Okusemqoka

Sekuyiminyaka eyizinkulungwane, ama-phytosterol abe yingxenye yokudla komuntu njengengxenye yemifino, izithelo, imidumba nokunye ukudla kwezitshalo.

Kodwa-ke, ukudla kwesimanje manje kuqukethe amanani aphakeme ngokwemvelo - ikakhulu ngenxa yokusetshenziswa kwamafutha emifino acolisisiwe nokudla okuqinisiwe.

Ngenkathi ukudla okuphezulu kwama-phytosterol kuthiwa kunempilo yenhliziyo, ubufakazi bukhombisa ukuthi maningi amathuba okudala isifo senhliziyo kunokukuvimbela.

Yize kukuhle ukudla ama-phytosterol ekudleni okuphelele kwezitshalo, kungcono ukugwema ukudla okunothisiwe kwe-phytosterol nezithasiselo.
