Lutein thiab Zeaxanthin - Super hnub qub rau lub qhov muag
May 15, 2017

Noj zaub mov zoo yog qhov tseem ceeb kom koj ob lub qhov muag noj qab nyob zoo thiab ua haujlwm zoo tshaj plaws hauv koj lub neej. Ob lub qhov muag tseem ceeb heev uas yuav txo tau koj qhov kev pheej hmoo rau cov kab mob hauv lub cev thiab cov kab mob cataracts muaj npe koj tsis paub txog: lutein (LOO) thiab zeaxanthin (zee-AH-ZAN-thin).

Lutein thiab zeaxanthin yog ob hom carotenoids (kuh-RAH-teh-noids), uas yog daj rau liab pigments pom dav hauv zaub thiab lwm yam nroj tsuag. Txawm hais tias lutein yog ib qho xim daj , hauv siab ntau nws tshwm sim txiv kab ntxwv-liab.

Nyob rau hauv cov xwm txheej, lutein thiab zeaxanthin tuaj yeem nqus dej ntau dhau lub zog kom tiv thaiv kev puas tsuaj rau cov nroj tsuag ntawm cov tshav ntuj, tshwj xeeb tshaj yog cov hluav taws xob lub teeb ci hu ua xiav teeb.

Ntxiv nrog rau qhov pom muaj nyob hauv ntau cov nroj tsuag ntsuab thiab cov txiv hmab txiv ntoo thiab zaub ntsuab, lutein thiab zeaxanthin muaj nyob rau hauv cov ntshav siab tshaj plaws ntawm lub qhov muag ntawm tib neeg lub qhov muag, muab cov tshuaj ntsuab rau xim liab. Qhov tseeb, cov tshuaj ntsuab kuj yog hu ua "macula lutea" (los ntawm Latin macula, lub ntsiab lus "nqaij ntawd," thiab lutea, lub ntsiab lus "daj").

Cov kev tshawb fawb tsis ntev los no tau pom muaj cov carotenoid thib peb hauv lub cev. Kev hu ua meso-zeaxanthin, qhov pigment no tsis muaj nyob rau hauv cov khoom noj thiab tshwm rau tsim tawm hauv retina los ntawm noj lutein.

Lutein thiab zeaxanthin tshwm sim muaj cov tshuaj antioxidant tseem ceeb hauv lub cev. Nrog rau lwm yam tshuaj antioxidants, nrog rau cov vitamin C, beta-carotene thiab vitamin E, cov pigments tseem ceeb no tiv thaiv lub cev los ntawm kev puas tsuaj ntawm cov dawb radicals, uas yog tsis ruaj khov molecules uas ua rau cov hlwb thiab ua si hauv ntau cov kab mob.

Ntxiv rau cov kev pabcuam tseem ceeb thiab qhov muag pom, lutein yuav pab tiv thaiv tus kabmob atherosclerosis (ua rau cov rog rog hauv cov hlab ntsha), tus kabmob uas ua rau lub plawv nres ntau tshaj. Yog tias koj xav tau cov khoom no, thov hu rau peb ntawm email: info@natural-field.com .

Qhov muag cov txiaj ntsig ntawm Lutein Thiab Zeaxanthin

Nws ntseeg tias lutein, zeaxanthin thiab meso-zeaxanthin nyob rau hauv lub pob tshuaj tiv thaiv lub teeb xiav ntawm kev nkag mus rau lwm cov qauv hauv lub retina, uas yog txo cov teeb meem ntawm oxidative kev puas tsuaj uas ua rau ua rau lub cev tsis meej pem (AMD).

Ntau cov kev tshawb fawb tau pom tias lutein thiab zeaxanthin los pab tiv thaiv AMD los sis qeeb qeeb ntawm tus kab mob:

Kev tshawb nrhiav luam tawm hauv Nutrition & Metabolism tau pom hais tias cov khoom noj haus uas muaj cov khoom noj uas muaj meso-zeaxanthin, lutein thiab zeaxanthin zoo nce ntau qhov kev pom ntsej muag ntawm lub tsho ntawm lub qhov muag ntawm cov neeg feem ntau. Lub pob zeb pigment ntseeg tias muaj kev tiv thaiv tawm tsam kev tsim kho ntawm lub cev tsis zoo.

Cov kev tshawb fawb luam tawm hauv American Journal of Epidemiology, Ophthalmology thiab Archives ntawm Ophthalmology pom muaj ntau theem ntawm lutein thiab zeaxanthin hauv kev noj haus yog txuam nrog qis tshaj ntawm AMD.

Ob txoj kev tshawb fawb tau luam tawm nyob rau hauv Kev Tshuaj Ophthalmology thiab Kev Tshawb Fawb Pom Zoo pom tias qhov muag nrog ntau theem ntawm cov pigments mas tsis tshua muaj los yog tsim muaj kev ua rau lub cev tsis zoo.

Nyob rau hauv kev tshawb fawb luam tawm nyob rau hauv Archives ntawm Biochemistry thiab Biophysics, cov kws tshawb fawb sau ntawv pom tias lutein, zeaxanthin thiab meso-zeaxanthin lim luv luv-wavelength lub teeb thiab tiv thaiv los yog txo cov cim ntawm dawb radicals nyob rau hauv retinal pigment epithelium thiab choroid. Lawv kuj hais tias sib xyaw ntawm cov carotenoids no zoo dua li ib qho ntawm cov tib neeg carotenoids ntawm tib qhov tag nrho.

Nyob rau hauv kev tshawb fawb tawm hauv phau Optometry, koom nrog AMD thaum ntxov uas noj 8 mg ib hnub twg ntawm kev noj haus ze ze rau ib xyoo txhim kho lawv cov hmo tsav tsheb thiab lawv qhov muag pom tau zoo dua qhov nruab nrab ntawm 1.5 cov kab ntawm daim duab qhov muag.
