Phytosterols , ama sterols plant, ayaa loo qoondeeyey awooddooda inay ku caawiso hoos u dhigidda heerka ladil bararka LDL . Daraasadaha qaarkood ayaa xusuusta ilaa 15% hoos u dhaca heerarka LDL marka ay qaataan meel kasta oo u dhexeeya 2 illaa 3 garaam oo ah phytosterols maalin kasta. Qaar badan oo ka mid ah makhaayadaha ayaa sidoo kale ogeysiiyey, inay faytosterols ku jiraan cuntooyin badan - sida faafidda iyo cunnada fudud - iyo waliba fitamiino.
Laakiin ma waxay tahay ammaan inay qaataan muddo dheer?
Inkastoo ay jiraan daraasado badan oo mudada gaaban ah oo soo jeediya in phytosterols ay hoos u dhigto LDL, maahan daraasado ku filan si loo baaro dhibaatooyinka muddada fog ee dheeraadka ah ee phytosterol ee aadanaha. Qeybta ugu badan, phytosterols ayaa si fiican u dulqaadan karta marka ugu horreysa ee ay bilaabantay, iyada oo ay la socdaan shakhsiyaadka qaarkood oo la kulma saameyno kale sida calool-gal, caloosha, ama calool-xanuun.
Si kastaba ha noqotee, daraasadaha eegaya saameynta iman karta ee muddada dheer ee ku-soo-gaadhista dheeraadka ah ee phytosterol ayaa ah mid aad u yar - iyo iskahorimaad. Daraasadaha qaarkood ayaa sheegay in qaadashada daawada sare ee phytosterols aysan yareyn karin LDL-gaaga oo kaliya - waxay sidoo kale yeelan kartaa saameyn dhexdhexaad ah ama hoos u dhigeysa khatarta cudurka wadnaha. Dhinaca kale, waxaa jira daraasado cilmi baaris ah oo soo jeedinaya in la isticmaalo daawooyin badan oo phytosterols ah oo waqti dheer ku kordhin kara khatarta ah in aad qaaddo cudurka wadnaha.
Fikradda ah in phytosterols ay ka qayb qaadan karto atherosclerosis badanaa waxay ka timaaddaa fiirsashada dadka iyo xayawaanka daawada phytosterols xaalad loo yaqaan ' sitosterolemia' .
Sitosterolemia, ama phytosterolemia, waa xaalad naadir ah oo la dhaxlo, taasoo keenta in si fudud loo nuugo phytosterols (gaar ahaan sitosterol) ee dhiigga, taas oo keenaysa inay ku ururaan jirka dhexdiisa iyo dhigaalka ku jira halbowlayaasha. Daraasaddan, kordhinta qaadashada phytosterol ee jiirarka iyo jiirka waxay keeneen dardar-xakin hindhisyada atherosclerotic ee ku jira kiimikada.
Mid ka mid ah daraasaddan ayaa sheegtay in xoojinta kordhinta xiniinyaha dhiigga ku jira ee dhiigga sidoo kale ay sababtay dhacdooyinka sii kordhaya ee dhacdooyinka wadnaha iyo xididdada ragga qaba cudurka wadnaha.
Intaa waxaa dheer, waxaa loo maleynayaa in isticmaalka dheeraadka ah ee cuntooyinka ay la socoto phytosterols ay sababi karto hoos u dhac ku yimaada helitaanka fiitamiinada-baruurta leh iyo antioxidants, sida beta-carotene, wakhti ka dib.
Sababtoo ah daraasadaha baaraya arimahani waa isku dhac, macluumaad dheeraad ah ayaa loo baahan doonaa si loo go'aamiyo wixii dhab ahaan ah, haddii ay jiraan, laga yaabo inay keenaan isticmaalka cuntooyinka dheeraadka ah ee kiniiniyada faytawan iyo kaniiniyada muddo dheer.
Sidaa darteed, haddii aad ka fekereyso inaad qaadatid daawooyinka phytosterol ama cuntooyinka lagu daray phytosterols, laakiin aad ka walaacsan tahay la'aanta macluumaadka ku saabsan nabadgelyada muddada dheer, waxaad u maleyn kartaa inaad ka heli karto fytosterolkaaga cuntooyinka caafimaadka leh sida:
- Miraha
- Khudaarta
- Nuts
- Miiraha oo dhan
Ilaa intaa ka badan oo la ogaado kordhinta dheeraadka ah phytosterol, Guddiga Nafaqada ee Wadnaha Wadnaha ee Maraykanku wuxuu kugula talinayaa in daawada phytosterols - haddii ay ku kordhiso cuntooyinka ama kaniiniga - waa in loo isticmaalo kaliya shakhsiyaadka leh kolestaroolka guud iyo / ama kolestaroolka LDL heerarka.
