Daim ntawv thov kev cia siab ntawm chromium nplua nuj poov xab

Nrog rau kev txhim kho txuas ntxiv ntawm tib neeg txoj kev ua neej nyob thiab kev noj zaub mov ntau ntxiv, qhov tshwm sim ntawm ntshav qab zib, hyperlipidemia thiab kab mob plawv tseem nce ntxiv. Kev tsim nyog chromium supplementation tuaj yeem tiv thaiv thiab kho cov kab mob no. Raws li kev npaj bioactive ntawm cov cim tseem ceeb chromium rau tib neeg lub cev, cov poov xab chromium tsis tsuas yog muaj cov txiaj ntsig zoo ntawm kev txo cov ntshav qab zib thiab cov ntshav lipids, tab sis kuj zam cov toxicity ntawm inorganic chromium ntsev, tswj tib neeg cov suab thaj, lipid, thiab protein metabolism, thiab yog ib qho kev nyab xeeb thiab muaj txiaj ntsig chromium ntxiv. Nws tuaj yeem pom tias cov poov xab chromium yuav siv dav dua yav tom ntej.
Raws li thaum ntxov xyoo 1959, Mery thiab Schroeder tau tshawb pom tias trivalent chromium yog cov khoom muaj txiaj ntsig ntawm cov piam thaj kam rau siab (GTF), uas pab insulin hauv kev tawm tsam biochemical hauv lub cev thiab muaj peev xwm txo cov ntshav qab zib thiab ntshav lipids. [Schambelan M, Blake S, Sraer J, et al. Ntau cov khoom tsim tawm los ntawm glossuli cais los ntawm cov nqi nrog streptozotocin induced ntshav qab zib hlau. J Clin Invest, 1985, 57:404.] Txij thaum ntawd los, cov kws tshawb fawb tau tshawb fawb ntau yam ntawm cov tshuaj chromium thiab pom tias cov chromium hauv cov neeg mob ntshav qab zib tau txo qis heev. Qhov kev sim tau lees paub tias kev ua haujlwm lom neeg ntawm insulin raug txo qis tom qab chromium deficiency hauv tib neeg lub cev, cov nyhuv ntawm cov ntaub so ntswg ntawm cov tshuaj insulin raug txo, lossis txawm tias tsis teb, thiab tom qab ntawd cov piam thaj ua rau tsis zoo. Thaum mob hnyav, ntshav qab zib nce ntxiv, thiab ntshav qab zib, ntshav qab zib yoo mov, thiab ntshav qab zib tshwm sim. Kev ua haujlwm qis chromium (xws li chromium chloride) tuaj yeem txhim kho cov mob ntshav qab zib. Levine (1968) thiab lwm tus tau ua pov thawj tias 50% ntawm cov neeg mob ntshav qab zib mellitus nrog cov piam thaj tsis txaus ntseeg tau txhim kho tom qab chromium supplementation rau 150 ~ 1000 μ g / d, 15 ~ 120 hnub. Vinson kho cov neeg mob ntshav qab zib siab nrog cov tshuaj chromium, thiab tom qab ob lub hlis ntawm kev kho mob, tus neeg mob cov qib glycated hemoglobin poob qis. Hauv xyoo 1996, Glinaman tau kho cov neeg mob ntshav qab zib uas tsis muaj peev xwm chromium chloride, thiab 40% ntawm cov neeg mob tau txhim kho lawv cov piam thaj ntev. Nrog rau kev tshawb fawb tob ntxiv thiab kev tsim cov tshuaj chrome tshiab, nws yuav tsum ua kom muaj txiaj ntsig zoo rau kev tiv thaiv thiab kho ntshav qab zib.
kev lag luam zaub mov
Cov poov xab chromium tsis tsuas yog muaj cov ntsiab lus siab chromium xwb, tab sis kuj muaj cov protein ntau, nucleic acid, glycogen, rog, biotin, ntau yam B vitamins, sterols, thiab lwm yam kab kawm. Yog tias ua rau cov poov xab chromium, nws kuj muaj ntau yam digestive enzymes, phosphatase, physiological active tshuaj xws li glutathione, thiab lwm yam. Nws cov khoom noj khoom haus thiab kev noj qab haus huv tus nqi deb tshaj li cov ntshiab chromium trichloride (muaj tsuas yog trivalent chromium ions). Cov khoom noj saum toj no tsis tsuas yog muaj qee yam khoom noj khoom haus thiab kev noj qab haus huv xwb, tab sis kuj tuaj yeem siv rau kev noj zaub mov ntxiv thiab kev ua zaub mov hauv kev lag luam zaub mov.
Nws cov ntawv thov tseem ceeb hauv kev lag luam zaub mov yog raws li hauv qab no:
(1) Nws yog tsim rau zus tau tej cov Dim sum, qhob cij, biscuits thiab lwm yam khoom noj ceev ceev fortified khoom noj khoom haus, nrog ib tug dav ntxiv ntawm 2-3%.
(2) Txhim kho qhov zoo ntawm Dim sum, qhob cij thiab khob cij, ua kom cov ductility, yooj yim rau kev khiav lag luam, thiab ntxiv 0.15 ~ 1%.
(3) Txhim kho qhov tsw ntawm cov zaub mov siav thiab khov los ntawm kev ntxiv 2-3%.
(4) Rau cov khoom noj uas muaj roj ntau thiab cov roj soluble vitamins (A, D, E, K), qhov sib ntxiv ntawm chromium poov xab tuaj yeem ua rau muaj kev tiv thaiv antioxidant, nrog rau ntau npaum li 1%.
(5) Chromium poov xab tuaj yeem txhim kho qhov adhesion thiab dej tuav ntawm cov khoom nqaij lawv tus kheej, nrog rau txhim kho lawv cov aroma. Ntxiv 1-3%.
(6) Chromium poov xab autolysis los yog enzymatic hydrolysis kua yog tov nrog ib tug npaum li cas ntawm cov txiv hmab txiv ntoo, seasoning kua txiv, thiab lwm yam. Nws tseem tuaj yeem sib xyaw nrog cov kua mis nyuj thiab cov mis nyuj thiab qhuav los ntawm tshuaj tsuag los tsim cov kua mis hypoglycemic thiab mis nyuj hmoov.
tshuaj tiv thaiv
Cov poov xab chromium muaj cov organic active chromium. Ntxiv nrog rau kev txo qis cov ntshav qab zib hauv cov neeg mob ntshav qab zib thiab TC, TG thiab LDL2C hauv cov neeg mob hyperlipidemia, cov poov xab chromium tuaj yeem txhim kho HDL2C los tiv thaiv atherosclerosis, tiv thaiv myocardium, txhim kho tib neeg cov piam thaj metabolism, rog metabolism thiab protein synthesis, tswj cov txheej txheem tertiary. ntawm nucleic acid, tiv thaiv denaturation los ntawm RNA cua sov, thiab tiv thaiv pathological hloov nyob rau hauv ib puag ncig los yog hauv nruab nrab lub paj hlwb. Cov poov xab chromium tuaj yeem siv los ua ob qho tshuaj kho kab mob thiab kev tiv thaiv kev noj qab haus huv zoo. Tsis tas li ntawd, raws li cov ntaub ntawv tseem ceeb hauv tsev thiab txawv teb chaws, ntxiv cov poov xab chromium kuj muaj txiaj ntsig zoo yuag thiab tuaj yeem siv los ua ib tiam tshiab ntawm cov zaub mov noj qab haus huv.
Tsiaj Tsiaj
Chromium tuaj yeem txhim kho kev ntxhov siab ntawm cov tsiaj txhu thiab cuam tshuam rau lub cev tiv thaiv kab mob. Raws li kev pub mis ntxiv, chromium tuaj yeem txhim kho kev siv tus nqi pub, txhawb kev loj hlob, txhim kho carcass zoo, thiab txhim kho kev ua me nyuam. Ntxiv cov poov xab chromium npaj rau tsiaj pub tsis tuaj yeem txo qhov kev puas tsuaj ntawm inorganic chromium rau tsiaj lub cev, tab sis kuj tseem txhim kho cov protein synthesis muaj peev xwm ntawm cov tsiaj lub cev, ua kom cov ntsiab lus ntawm ntau yam enzymes uas xav tau rau cov leeg nqaij protein synthesis hauv lub cev, txhawb cov leeg nqaij protein synthesis, nce nqaij ntshiv feem pua, txo cov rog deposition, thiab yog li txhim kho cov nqaij tsiaj zoo.
Nws tau pom nyob rau hauv kev sim tshuaj uas noj chromium poov xab tsis tuaj yeem txo qhov xav tau ntawm exogenous insulin thiab ntshav qab zib ntawm cov neeg mob ntshav qab zib hom II, tab sis kuj txo tag nrho cov cholesterol los ntawm 10%, high-density lipids (HDL) los ntawm 14%, thiab Qhov sib piv ntawm tag nrho cov roj (cholesterol) mus rau high-density lipids li ntawm 17% hauv cov neeg mob uas muaj kab mob plawv. Ntxiv cov poov xab chromium siab rau zaub mov tuaj yeem tiv thaiv thiab tswj qhov tshwm sim ntawm Congee cov tsos mob. Chromium deficiency kuj yog ib qho pathogenic yam ntawm arterial Congee.
Yog li, chromium, ib qho ntawm cov kab mob, ua lub luag haujlwm tseem ceeb hauv kev noj qab haus huv ntawm tib neeg thiab tsiaj txhu. Yav dhau los, muaj kev nce qib tsawg dhau ntawm thaj chaw no, thiab ntau tus neeg tsis paub ntau lossis tsis muaj kev nkag siab tob. Kuv vam tias cov neeg ua haujlwm kho mob, cov neeg ua haujlwm thev naus laus zis, kws tshaj lij khoom noj khoom haus, thiab xov xwm tshaj tawm tuaj yeem qhia paub ntau ntxiv txog cov kab ke rau peb cov neeg nyob hauv lub tebchaws thiab cov kws ua tsiaj txhu. Kuv ntseeg tias nws yuav ua lub luag haujlwm zoo hauv kev txhim kho lub cev muaj zog ntawm tag nrho cov pejxeem thiab txhawb kev vam meej ntawm cov nqaij qaib thiab tsiaj txhu.
