Phytosterols, yomwe imatchedwanso kuti sterols chomera, yathandizidwa kwambiri chifukwa cha zabwino za mtima wawo. Kawirikawiri mumapezeka zakudya zakuthupi, monga mtedza, zipatso, ndi masamba, phytosterols ingapezenso mawonekedwe owonjezera mu sitolo kapena mankhwala.
Kafukufuku apeza kuti kulikonse komwe kuli pakati pa 1.6 ndi 3 magalamu a phytosterols kungachepetse cholesterol cha LDL pakati pa 4 ndi 15%.
Komabe, chotupa cha HDL ndi triglycerides sichikuwoneka kuti chikukhudzidwa kwambiri ndi kugwiritsidwa ntchito kwa phytosterols. Ngakhale njira yomwe LDL cholesterol imatsitsidwira ndi tizilombo toyambitsa matenda sichidziwikiratu, pakhala pali maphunziro ena omwe asanthula momwe phytosterols ingakhudzire mliri wa cholesterol wanu LDL.
Njira Yotsitsira LDL Ndi Yopanda
Kawirikawiri, cholesterol-zonse kuchokera ku chakudya chanu ndi chiwindi-zimalowa m'matumbo aang'ono ndipo zimazungulira m'magazi.
Mankhwala a phytosterols, omwe ali ndi mawonekedwe ofanana ndi ma molekule a cholesterol, amachotsedwa pang'ono kuchokera m'mimba yaing'ono. Choncho, phytosterols salowerera m'magazi ndipo m'malo mwake amasungidwa. Kafukufuku wina apeza kuti tizilombo toyambitsa matenda tingathe kuimitsa kapena kuchepetsa kuyamwa kwa kolera. Kafukufukuyu apeza ma molekyulu m'matumbo aang'ono omwe mwina akhoza kusinthidwa ndi tizilombo toyambitsa matenda, monga adenosine triphosphate cassette yomwe imangotumiza wogulitsa A1 (ABCA1).
Mamolekyu awa ali ndi udindo wowonjezera chisamaliro cha cholesterol mu nyansi. Kafukufuku wina amasonyeza kuti phytosterols ingakhudze mmene cholesterol imagwiritsidwira ntchito m'thupi. Kafukufukuyu wasonyeza kuti phytosterols ingathandize kuchepetsa kuchuluka kwa VLDL cholesterol, IDL cholesterol ndi cholesterol cha LDL chomwe chimachitidwa m'chiwindi.
Mwamwayi, maphunzirowa akutsutsana ndi momwe ma phytosterols amachitira izi sizidziwika bwino.
Ngakhale kuti pakufunika maphunziro ochulukirapo kuti mudziwe mmene phytosterols amagwiritsira ntchito kuchepetsa cholesterol chanu cha LDL, kafukufuku wasonyeza kuti kuphatikizapo zakudya za phytosterol mu zakudya zanu ndi kuchepetsa mafuta ochulukirapo omwe mumadya mungathandizire kuchepetsa mayendedwe anu a LDL. Ngakhale zakudya zambiri zathanzi zili ndi phytosterols, mwina sikukwanira kuzindikira kuti cholesterol-kutsika kwa mcherewu. Mwachitsanzo, ngakhale kuti 2 magalamu a phytosterols tsiku ndi tsiku amafunika kuchepetsa kuchepetsa kuchepa kwa kadolesitolini ya LDL, akuti munthu wamba yekha amapeza pafupifupi 150 mpaka 350 mg ya phytosterols tsiku ndi tsiku. Zakudya zowonjezera mavitamini ndi zakudya zomwe zimalimba ndi phytosterols zingathandizenso kuonjezera kudya kwa phytosterol.
