Daraasado badan ayaa muujiyey in shaaha uu leeyahay faa'iidooyin caafimaad oo badan oo ku saabsan biyaha, shaaha ayaa ah cabbitaanka labaad ee ugu badan dunida oo dhan. Daraasado badan ayaa muujiyay in shaaha uu leeyahay faa'iidooyin caafimaad oo badan - oo ay ku jirto saameyn togan ku yeelata heerarka kolesteroolka.
Noocyada kala duwan ee Shaaha
Shaaha waxaa laga soo qaatay dhirta Camellia sinensis waxaana lagu sifeeyay saddex qaybood oo waaweyn:
- Shaah cagaaran
- Shaaha Oolong
- Shaah madow
Noocyada shaaha noocan ah, shaah cagaaran waa tan ugu caansan, tan iyo markii loo isticmaalay daawada qadiimiga ah si loo daaweeyo cudurada sida dhiigbaxa iyo dheefshiidka.
Qaxwaha cagaaran wuu ka duwan yahay noocyada kale ee shaaha sababtoo ah waxa ay hoos u dhigtay ka shaqeynta yar. Maadaama aysan ku dhacin hannaanka halsano badan sida shaaha kale, qaar badan oo ka mid ah antioxidants, gaar ahaan loenins, waa la ilaaliyaa. Waxqabadka antioksidant ee catenins waxaa loo yaqaanaa noocyo kala duwan oo faa'iidooyin caafimaad ah, oo ay ka mid tahay ka hortagga kansarka, dhiirigelinta caafimaadka afka, yareynaya rheumatoid arthritis , iyo waxqabadka bakteeriyada. Hadda, shaahaaga cagaaran ayaa sidoo kale ku soo caan baxa si loo yareeyo kolestaroolka.
Sidee waxtar leh ayaa shaahaagu u yar yahay shaaha?
Inta badan daraasadaha ku lug leh saameynta shubanka hoose ee shahwada cagaaran waxaa ka mid ah isticmaalka shaaha firfircoon ee firfircoon ee firfircoon, kalluunka laga soo saaro, sida ka soo horjeeda cabitaanka laftiisa.
Habka shaaha oo hoos u dhigaya kolestaroolka ayaa inta badan aan la aqoon, laakiin waxay u muuqataa in:
- Kordhinta waxqabadka qaaxada ee LDL ee beerka
- Ka hortag nuugista kolestaroolka mindhicirka
- Kolestaroolka hoose ee LDL
- Kordhi kolestaroolka HDL
- Wadarta guud ee kolestaroolka
Mid ka mid ah daraasaddan ayaa baadhay saamaynta kolesteroolka ee 375 mg oo kalluunka laga soo saaray 200 oo ragga iyo haweenka qaba kolestaroolka sare ee cunto yar oo dufan ah.
Cilmi-baadhayaashu waxay ogaadeen in dheecaanka kalluunka uu hoos u dhigo kolestaroolka boqolkiiba 11.3, kolestaroolka LDL by 16.4 boqolkiiba, triglycerides by 3.5 boqolkiiba, iyo kor u HDL by 2.3 boqolkiiba. Si kastaba ha ahaatee, wax soo saarka kalluunka ee loo isticmaalo daraasaddan, si kastaba ha ahaatee, ma ahaa mid saafi ah oo ka kooban 75 mg of theaflavins (antioxidant oo laga helo shaaha madow), 150 mg oo ah walxaha shaaha ee cagaaran, iyo 150 mg oo ah polyphenols shaaha kale. Sidaa darteed, kaliya qayb yar oo ka mid ah soo saarka caleenta badeecadda ee laga helay shaaha cagaaran ayaa loo adeegsaday daraasaddan. Intaa waxaa dheer, daraasaddan waxay soo jeedineysaa in aad u baahan tahay inaad cabto cabitaano badan oo shaah cagaaran si aad uga hoos marsiiso kolesteroolka oo aad hesho natiijooyinka lagu arkay daraasaddan.
Daraasadaha qaarkood waxay muujiyeen wax soo saarka kalluunka ee laga helo shaaha cagaaran oo hooseeya iyo heerarka hoose ee LDL kolesteroolka 60 boqolkiiba iyo boqolkiiba 80. Si kastaba ha noqotee, badi ka mid ah daraasaddan waxay ku kala duwanyihiin xaddiga kalluunka caleenta loo isticmaalo iyo xaaladda ka qaybgalayaasha. Inkasta oo natiijooyinkaas la rajeynayo, daraasado kale ayaan awoodin in la diiwaangeliyo saamaynta dufanka shubanka ee shaaha cagaaran. Tusaale ahaan, daraasadda ugu dambeysay ayaa lagu soo gabagabeeyay in 3.8 g oo laga soosaaray kalluunka (ilaa 18 koob oo ah shaaha cagaaran) ama lix koob oo shaah cagaaran ah oo aan waxtar lahayn ee hoos u dhigaya kolestaroolka.
Si kastaba ha ahaatee, dhammaan ka qaybgalayaasha daraasaddan waxay ahaayeen kuwa sigaar cabba. Sidaas, natiijadan waxaa loo turjumi karaa laba siyaabood. Ugu horreyn, tani waxay soo jeedin kartaa in sigaar cabbidku uu diidayo awoodda dufanka "cholesterol-down-downing" ee kalluunka lagu helo shaaha cagaaran. Tan labaad, natiijooyinkani waxay soo jeedin karaan in shaaha loo yaqaan 'shaaha' ee cagaaran aaney waxtar u lahayn hoos u dhigista kolestaroolka, sidaas awgeed ayaa isku dhafan daraasado kale oo soo jeediyay in kalluunka qoyan ee cagaaran uu hoos u dhigo kolestaroolka. Waqtigan xaadirka ah, cilmi-baarayaashu ma ogaanayaan jawaabta su'aasha ah in ay tahay ama haddii aan la helin kalluunka cagaaran ee hooseeya. Daraasado badan ayaa loo baahan yahay in la sameeyo si loo sii baaro su'aashan.
Sanadkii 2006, codsi ayaa loo gudbiyay FDA si ay u siiso cabitaanka shaaha ee cagaaran si ay u qaadaan sheegashada caafimaadka ee ay hoos u dhigeen cudurka wadnaha. Si kastaba ha ahaatee, Maamulka Cuntada iyo Maandooriyaha ayaa diidey codsigan, isaga oo sheegay in caddeyn dheeraad ah loo baahan yahay si loo xaqiijiyo sheegashadan.
Marka la soo koobo, baaritaannada hadda jira ee ku saabsan shaah cagaaran iyo awooddooda inay hoos u dhigto kolestaroolka ayaa iska hor imanaya, mana jirto baadhitaan ku filan oo loo oggol yahay in qofku u sheego in shaah cagaaran uu hoos u dhigo kolestaroolka.
Ma cabtaa noocyada kale ee shaaha?
Sida laga soo xigtay cilmibaadhista hadda, shimbiraha oolong iyo madow waxay sidoo kale yeelan karaan saameyn ku yeelan kara kolestaroolka sababta oo ah joogitaanka bakteeriyada nooca antioxidants ee shaaha. Si kastaba ha noqotee, daraasadaha qaar, shimadahan uma muuqdaan inay shaqeeyaan iyo sidoo kale shaah cagaaran. Tani waxaa laga yaabaa in ay sabab u tahay xaqiiqda ah in shaaha kuwaas oo maraya geedi socodka halsano badan oo ka badan shaah cagaaran.
