Noo rog - qhov zoo thiab qhov raug mob

Cov luam tawm cov ntaub ntawv ntawm lub xeem peb xyoo lawm qhia tias noo yam muaj lub ntsiab ua rau ntawm cov hlab plawv tus kab mob. Tab sis niaj hnub no, zaum muaj pov thawj hais tias qhov no yog tsis muaj tseeb. Kev tshawb fawb tau qhia tias cov hluas tsis tas cais rog los ntawm koj cov zaub mov. Yog hais tias peb tham txog cov neeg laus, cov kev txwv nyob rau hauv lawv cov kev txais neeg kawm yog tseem ncav siv tau.

Ib txhia zaum ntseeg tias nyeem rog yog zoo txog rau tib neeg noob caj noob ces yog muab kev koom tes nyob rau hauv metabolic dab, yog yam ntxwv Cheebtsam ntawm lom week, thiab lwm yam Neeg ua hauj lwm ntawm lub tsev kawm ntawv ntawm Cardiff muaj pov thawj hais tias cov mis nyuj muaj roj thiaj li txoj kev pheej hmoo ntawm tus kab mob plawv thiab cov hlab ntsha. Yog li ntawd, cov kws kho mob yuav tsum tau mus tseem siv tag nrho cov mis nyuj, tsis yim. Cov kev siv ntawm cov khoom no los ntawm cov me nyuam thiab cov tub ntxhais tus neeg ua tsim kev mob ntau tshaj kev zoo. Nyob rau hauv kev noj haus yog tsim nyog los txwv cov naj npawb ntawm "phem" trans-rog, piam thaj thiab ntsev.

Niaj hnub no peb paub tias nyeem rog tsis ua koj qhov hnyav nce. Feem ntau, txoj kev no yog vim tus tseem ceeb npaum li cas ntawm carbohydrate noj. Cov kev siv ntawm ib tug tsawg kawg nkaus tus nqi ntawm cov roj ua lub kev loj hlob ntawm ntau yam kab mob. Feem ntau, qhov no yog kev cob cog rua nrog fat-soluble vitamins A, D, E, K, F. Cov ntsiab yuav tsuas tsis yuav absorbed los ntawm lub cev tsis muaj txaus lipids. Raws li ib tug tshwm sim, muaj hypo- thiab avitaminosis. Peb yuav tsum tsis txhob hnov qab hais tias ob steroid cov tshuaj hormones thiab cov kua tsib acids yog muab tau lipids. Sibhawm - zoo heev insulating cov ntaub ntawv uas, ib tug tseem ceeb qhov chaw ntawm lub zog, dej thiab ib tug endogenous substrate rau lub synthesis ntawm ib tug xov tooj ntawm bioactive tebchaw rau ib tug kab mob.

Thiab tseem yuav tau xyuas seb dab tsi yog cov rog. Science News for KIDS ntawm cov nqaijrog (lipids)

Tag nrho cov ntawm lawv yog muab faib ua peb pawg loj: yooj yim, complex thiab derivatives. Cov thawj pab pawg neeg yog cov neeg uas muaj glycerol (trihydric cawv) thiab ntau dua fatty acids. Qhov no pab pawg neeg no muaj xws li triacylglycerols, sterols thiab waxes. Lub molecule muaj glycerol lipid complex, siab dua fatty acids, phosphate thiab sulfate acids, nitrogenous tshuaj, carbohydrates thiab ntau lwm tebchaw. Lub derivatives xws li carotene lipids, fatty acids, siab dua alcohols, ib co fat-soluble vitamins , thiab lwm yam

Nrog kev xav txog ntau dua fatty acids nyob rau hauv lub rog, lawv yog feem ntau uas muaj tuaj acyclic nyeem thiab unsaturated fatty acids. Muaj pes tsawg leeg ntawm ib co rog yog cyclic carboxylic acids, thiab hydroxyacids. Nyeem cov rog muaj theem ntawm palmitic, stearic, myristic acid. Nws yog ib qho kev paub hais tias ib co unsaturated fatty acids uas yog tsis ua nyob rau hauv lub cev los yog tsim nyob rau hauv tsis txaus, ib tug tsawg kawg nkaus tus nqi. Nyob rau hauv no hais txog, lawv hu ua nrog qhov tseem ceeb los yog indispensable. Yuav kom qhov no pab pawg neeg yuav arachidonic, linoleic, linolenic acid. Qhov tseem ceeb fatty acids nyob rau hauv txaus tus nqi zaub roj. Cov mis nyuj muaj roj muaj ib tug loj npaum li cas ntawm arachidonic acid. Monounsaturated nqaijrog muaj ib tug lossis loj npaum li cas oleic acid.

Nyob rau hauv tib neeg, cov roj nyeem (triacylglycerides) yog siv raws li lub zog cov ntaub ntawv uas. Cov no muaj xws cov neeg ntawm cov tsiaj keeb kwm, raws li tau zoo raws li cov khoom zaub. Triacylglycerols nyob rau hauv ntau cov nqaij cov khoom ntawm fatty nqaij thiab khoom noj siv mis, qhob noom xim kasfes thiab confectionery khoom. Ntau tau ntawm cov rog no yuav ua rau ib qho kev nce rau hauv lub concentration ntawm cov roj uas txhaws nyob rau hauv lub cev. Yog li ntawd-hu ua "pathological" cholesterol tso rau ntawm cov phab ntsa hauv cov hlab ntsha, uas nyob rau hauv lem, ua rau txoj kev loj hlob ntawm tej kab mob raws li atherosclerosis, vascular elasticity yog tawg, yog tsim los ntshav.

Nutritionists kom noj ib tug me me npaum li cas ntawm cov roj nyeem. Cov teeb meem feem ntau rau lub cev pom tau hais tias yuav trans-rog. Tej isomers yog tsim vim qhov kev txiav txim ntawm lub cev thiab tshuaj yam rau zaub rog, uas hloov lawv lub cev rau lub xeev ntawm cov kua rau khoom. Rau cov neeg muaj xws li margarine thiab confectionery thiab ua noj ua haus roj. Lawv yuav ua tau ib carcinogenic nyhuv.
