Peb Lub Caij Tsis Tsim Nyog Txog Koj LDL
Txawm hais tias muaj ntau yam kev noj qab haus huv feem ntau ua rau kev noj zaub mov tsawg tsawg ( triglycerides , HDL roj cholesterol, ntshav qabzib, ntshav siab, duav / khwb siab, thiab lwm yam), feem ntau ntawm cov neeg siv cov roj LDL roj ntau dua, cov neeg muaj kev txo thiab lwm tus neeg nce. Qee cov neeg ua pa taws yog tias lawv pom tias tus lej nce toj ntxiv, thaum lawv cov kws kho mob tau ncav cuag cov tshuaj rau cov tshuaj.
Tab sis muaj tsawg kawg yog peb yam coj los ua kom sib sib zog nqus pa ua ntej yuav ua ntxiv.
Cov Tshuaj Cholesterol Yog Dab Tsi?
Roj (cholesterol) yog ib co roj substance uas muaj feem rau cov rog. Txawm tias LDL roj cholesterol feem ntau hu ua "phem", kuv xav tias nws tseem ceeb heev kom nkag siab tias roj (cholesterol), hauv thiab ntawm nws tus kheej, tsis yog txhua qhov phem - qhov tseeb, nws yog qhov tseem ceeb rau peb lub cev khiav. Nws tsis yog tshob rau ntawm rooj plaub hais tias peb yuav tuag tsis muaj cov cholesterol. Cov roj cholesterol yog ib feem ntawm peb lub xovtooj ntawm lub cev thiab cov kabmob myelin insulating peb lub hlwb. Nws kuj siv los ua ntau ntau cov tshuaj hormones (xws li cov tshuaj no thiab cov tshuaj testosterone), vitamin D, cov tshuaj uas tseem ceeb heev rau kev zom cov zaub mov, thiab ntau ntxiv. Peb lub cev siv tshuaj cholesterol - nyob ntawm peb cov kev noj haus tsis tau, nyob qhov twg ntawm 80-100% ntawm cov roj cholesterol hauv peb lub cev yog ua "hauv tsev".
LDL Cholesterol Yog Dab Tsi Li Cas?
Nws yog nquag tham txog ntau hom "hom roj cholesterol", tab sis qhov no tsis yog qhov tseeb.
Tag nrho cov cholesterol molecules yog tib yam nkaus; nws tsuas yog hais tias lawv tau ntim rau hauv ntau txoj kev uas yuav raug xa mus los ntawm peb cov ntshav. Tus "thauj qauv" hu ua lipoprotein. HDL yog luv luv rau "high-density lipoprotein" thiab qee zaus hu ua "cov roj cholesterol zoo". LDL yog luv luv rau "qis lipoprotein" thiab feem ntau hu ua "roj cholesterol tsis zoo".
(Muaj ib feem peb, hu ua VLDL rau "lipoprotein tsawg heev", uas yog hu ua "phem tshaj plaws", tab sis nws muaj tsawg dua ntawm nws.) Nws yog LDL uas yog ze tshaj plaws nrog kev mob plawv ntsig txog plab nyob rau hauv cov hlab ntsha.
Tab sis tos, muaj ntau tshaj! HDL thiab LDL ob leeg tau muab faib ua ntau hom, thiab ntau dua yog tau pom hais txog ntau hom "pawg hauv pawg" ntawm lipoproteins. Nyob rau hauv rooj plaub ntawm LDL, qhov loj tshaj qhov txawv ntawm hom yog qhov loj thiab qhov sib txawv ntawm cov khoom ntawm LDL. Ntau tus neeg tau pom hais tias tag nrho LDL tus naj npawb tsis yog txhua yam uas zoo rau kev twv seb leej twg yuav mus kom tau kab mob hauv lub plawv, tab sis nrhiav tau ntawm cov qauv ntawm qhov loj me me tau muab cov kws kho mob ntau ntxiv txog kev txaus ntshai ntawm LDL ntawm ib qho tus neeg yog. Tab sis ntau ntxiv txog qhov # 2 hauv qab no - ua ntej kuv xav briefly hais:
1. LDL Elevation Feem ntau Ib Ntus
Muaj ob peb cov kev tshawb fawb tam sim no nrhiav LDL ntawm cov zaub mov tsawg-carb. Hauv qee qhov ntawm lawv, muaj ib txoj kev xav rau qee cov neeg los ua kom LDL nce siab ntawm 3-4 lub hlis, tab sis thaum lub hli 6 lossis 8, nws rov qab mus. Kuv tau hnov ntau cov dab neeg nyob rau hauv cov kab no los ntawm cov neeg tsawg-tsawg. Yog li nws zoo li ceev faj kom koj txhais tes tawm ntawm lub pob nyem khawm thaum lub hli pib ntawm koj qhov kev pabcuam noj zaubmov uas tsis tshua muaj nqi.
(Qhov laj thawj rau qhov tshwm sim no, raws li qhov kuv paub, tsis paub, tab sis nws tau raug hais tias cov roj cholesterol hauv cov roj hlwb yuav raug tso tawm mus rau hauv cov ntshav cov ntshav thaum lub cev qis, thiab yuav yog qhov tseem ceeb hauv thawj ob peb lub hlis thaum poob phaus sai heev.)
2. Particle Size Patterns Feem ntau yog txhim kho rau Low-Carb Diet
Li ntawd, yog vim li cas peb thiaj mob siab txog qhov loj ntawm cov khoom ntawm LDL? Nws hloov tawm tias thaum koj muaj ntau me me, ntom LDL feem (hu ua Pattern B), nws yog ntau yam ntxiv ntawm kev mob ntsws coronary artery dua li thaum lub ntsiab lus loj thiab tsawg ntom (Qauv A).
Nyob rau hauv txhua txoj kev tshawb no kuv paub txog tias saib LDL particle loj thaum tib neeg hloov mus noj zaub mov tsawg-tsawg, cov qauv hloov hauv cov kev taw qhia zoo.
Vim li cas cov ntsiab lus loj dua ntawd zoo dua? Kuv hnov ib zaj dab neeg ntawm Dr. Mark Houston (hnov qhov sib tham ntawm no - nws yog los ntawm lub Yim Hli 25, 2012, qhia txog "Thov Dr. Dawn"). Nws piav qhia hais tias tsis yog lub tswv yim ntawm cov roj cholesterol tsuas tsim tawm hauv ib qho ntawm cov hlab ntsha xwb, nws yeej pib nyob rau hauv txheej ntawm cov leeg ntsha hauv epithelium (uas zoo li "tawv nqaij" ntawm cov leeg) thaum muaj kev puas tsuaj thiab o nyob rau hauv lub epithelium.
Cov roj cholesterol (los yog, ntau dua, lipoprotein) hais los ntawm cov ntshav ces lodge nyob rau hauv cov txheej txheem txheej txheem epithelial thiab tsim los ntawm qhov ntawd los ua cov quav hniav. Thaum nws loj tuaj, cov quav hniav pib tawm tsam cov leeg. Hauv kev piav qhia txog qhov loj ntawm kev loj me me, Dr. Houston tau qhia txog zaj lus piv txwv no: Xav txog qhov net ntawm lub tsev txiav plaub tennis. Ib lub pob tes ntaus pob tesneb yuav tsis mus los ntawm qhov net, tabsis yog tias koj muab ib pawg ntawm golf npas ntawm qhov net, qee qhov ntawm lawv yuav dhau mus. Qhov no ua rau lub tswv yim zoo xav txog vim li cas cov me, LDL feem sib txawv dua li qhov loj, "fluffier" ua piv txwv - cov me, cov hnyav hnyav dua tuaj yeem ua rau hauv qhov chaw ntawm qhov kev puas tsuaj. (Dr. Houston kuj hais tias cov naj npawb ntawm LDL hais kuj tseem ceeb.)
Koj yuav tsis paub txog LDL feem ntawm ib qho kev kuaj cholesterol. Koj tus kws kho mob yuav tsum tau hais kom muaj kev ntsuam xyuas tshwj xeeb. Cov no yog ob qho tib si tshaj plaws:
- Vertical Auto Profile (VAP)
- Gradient Gel Electrophoresis (GGE)
3. LDL Feem ntau Tsis Ntsuas ncaj qha, Uas Yuav Ua Tau Teeb Meem
Nws hloov tawm tias nws tsis yooj yim los ntsuas LDL ncaj qha, vim li no feem ntau siv cov qauv mis los ntawm LDL los ntawm lwm yam kev ntsuas ntshav. Nws yog hu ua Friedewald equation thiab qhov no yog: LDL = Tag Nrho Cov Cholesterol - HDL - (Triglycerides / 5). Rau cov neeg feem coob, cov mis no zoo nkauj heev, tab sis cov lej ntawm kev ua lej yuav paub tias ib txoj kev "txhim kho" koj tus qhab nia LDL yuav ua kom koj cov kab mob triglyceride los ntawm, xws li, noj ib pawg qab zib. (Tsis yog lub tswv yim zoo !! Qhov no tsuas yog taw tes tawm ib qho teeb meem.) Tam sim no, nws paub tias thaum triglycerides siab heev (tshaj 400 mg / dL) qhov zauv tsis ua tiav qhov tseeb. Tab sis kuj muaj kev poob siab ntxiv tias thaum triglyceride feem ntau tsis qis LOW (hauv qab 100) tus LDL kuj yuav ua rau siab dhau los ntawm kev siv hom mis no. Muaj ob peb cov kev tshawb fawb txog qhov no, thiab cov lus qhia los ntawm cov kws kho mob uas siv cov kev txwv carbohydrate raws li ib feem ntawm lawv kev kho rau kev rog thiab ntshav qab zib. Cov neeg uas noj cov zaub mov uas tsis tshua noj zaub mov uas ua raws li kev noj zaub mov uas pheej yig ua rau lawv pom tias lawv cov triglycerides poob qis dua 100 (tsawg kawg yog ib tus kws kho mob, Dr. Mary Vernon, siv cov roj ntsha hauv plab los ua ib qho ntawm cov cim qhia qhia rau nws seb tus neeg mob puas ua raws li kev noj haus ). Yog li ntawd, yog tias triglycerides tsawg tsawg thiab LDL siab, nws yuav yog ib lub tswv yim zoo los thov kev sim uas ntsuas LDL ncaj qha tsis siv cov Friedewald formula.
Ib qho ntawm cov pab pawg uas tau kawm txog qhov no (Ahmadi et al) tau tsim ib qho kev ua dua lwm qhov, feem ntau hu ua Iranian qhov kev sib npaug. Txawm hais tias nws tseem ceeb heev kom paub tias qhov kab zauv no tsis tau lees txais nyob rau hauv Teb Chaws Asmeskas kev kho mob siab, nws yuav nthuav tau los piv koj LDL-derived los ntawm cov sib npaug sib txawv.
Interestingly, muaj triglycerides hauv qab 100 kuj muaj kev sib raug zoo nrog Qauv LDL particle size (tus qauv kev noj qab haus huv). Yog li, yog tias tom qab koj noj zaub mov tsawg tsawg thiab muaj cov mob triglycerides, nws muaj ob lub hauv paus tsis muaj kev txhawj txog koj cov roj ntsha LDL, tsawg kawg txog thaum koj tau kuaj ntxiv.
