Lub cev rog yog cov lwg me me uas muaj ib txoj saw cov pa roj carbon atoms nrog rau oxygen ob zaug sib txuas thiab hydroxyl pawg (ib qho oxygen thiab hydrogen atom) ib leeg sib khi ntawm ib kawg. Omega 3 fatty acids yog "polyunsaturated," txhais tau hais tias lawv muaj ntau qhov kev sib txuas ob leeg thoob plaws lawv cov xov tooj carbon thiab lawv thawj ob daim ntawv cog lus nyob nruab nrab ntawm cov pa roj carbon atoms tus lej peb thiab plaub thaum suav txog ntawm qhov kawg ntawm cov saw mus kom deb ntawm pab pawg hydroxyl.

Thov txim ntawm txhua yam tshuaj lom neeg, tab sis kuv nqa nws ob peb yam tseem ceeb. Firstly, tag nrho cov kev sib txuas ob npaug ua rau omega 3 fatty acids uas tsis ruaj khov thiab tsis zoo rau cov neeg sib tw rau oxidation, uas ua rau muaj kev tsis sib haum xeeb. Tsis tas li, dev tsis tuaj yeem ua lawv tus kheej omega 3 fatty acids vim tias lawv muaj sia tsis muaj peev xwm muab txoj kev sib txuas ob ntawm carbons 3 thiab 4. Qhov no yog vim li cas cov dev muaj kev xav noj rau omega 3 fatty acids uas zoo li eicosapentaenoic acid (EPA) thiab docosahexaenoic acid (DHA).

Cov roj zaub nrog rau cov roj flaxseed, canola roj, roj Walnut, thiab cov roj ntses muaj peev xwm muab cov dev nrog lwm omega 3 fatty acid hu ua alpha-linolenic acid (ALA), uas yog qhov kev qhia ua ntej rau EPA thiab DHA. Txawm li cas los xij, dev tsis zoo heev ntawm kev hloov ALA mus rau EPA lossis DHA. Yog li ntawd, nws tau ntau dua los muab cov dev nrog EPA thiab DHA ncaj qha.

Thaum nriav cov omega 3 fatty acid ntxiv, xaiv ib qho uas ua los ntawm cov chaw tsim khoom muaj koob npe nrov uas muab cov ntaub ntawv hauv qab no xws li ntawm cov khoom lag luam lossis ntawm lawv lub vev xaib:

  • Qhov ntau ntxiv EPA thiab DHA puas muaj cov kev ntsuas ntxiv?
  • Yuav ua li cas lawv huv lawv cov khoom kom tshem tawm cov kuab paug xws li cov tshuaj lom?
