Spoiler: lawv yog superfluous rau koj lub cev.

Trans fats yog dab tsi thiab lawv tuaj qhov twg?

Hauv cov lus "tshuaj" nruj, cov rog trans yog unsaturated fatty acids hloov nyob rau hauv ib txoj kev tshwj xeeb.

Los ntawm lawv tus kheej, unsaturated fatty acids tseem ceeb heev rau lub cev. Txawm li cas los xij, lawv muaj ob qhov teeb meem loj vim yog cov qauv ntawm Dab Tsi Rog? - Muaj nuj nqi & Molecular Structure.

Saturated fatty acids muaj ib tug nruj crystalline qauv. Qhov no ua rau cov rog uas lawv muaj nyob rau hauv chav tsev kub. Creamy, txiv maj phaub, cocoa butter yog qhov piv txwv tseem ceeb. Tab sis nyob rau hauv cov tshuaj formula ntawm unsaturated acids, tsis muaj hydrogen atoms txaus. Vim li no, cov rog raws li lawv yog cov kua ntau dua, yas. Feem ntau ntawm cov kua zaub roj yog unsaturated fats.

Cov roj ua kua yog qhov nyuaj rau siv hauv cov khoom ci. Tsis tas li ntawd, vim muaj nyob rau hauv cov qauv ntawm unoccupied hydrogen "qhov chaw dawb", lawv tau oxidized sai, uas yog, deteriorate.

Txhawm rau tshem tawm cov rog tsis txaus ntawm cov teeb meem no, chemists tau kawm los txuas cov hydrogen atoms rau lawv, ua rau cov qauv ruaj khov dua. Cov txheej txheem no hu ua hydrogenation (los ntawm Latin hydrogenium - "hydrogen"). Qhov no yog li cas cov roj unsaturated - hydrogenated roj thiab margarines - tshwm sim.

Thaum lub sij hawm hydrogenation, hydrogen atoms txuas nrog qhov tsis ncaj ncees lawm thiab tsis zoo ib yam li hauv cov roj saturated. Ib qho ruaj khov tab sis tag nrho cov qauv tshiab molecular yog tsim. Nws tau hu ua daim ntawv trans. Thiab cov rog uas tshwm sim yog cov rog trans.

Nyob rau tib lub sijhawm, cov rog rog kuj pom muaj nyob rau hauv cov xwm txheej, piv txwv li, hauv cov nqaij thiab cov khoom noj siv mis nyuj tau los ntawm cov ruminants - nyuj, tshis, yaj. Natural trans fats yog tsim los ntawm cov kab mob. Cov ntsiab lus ntawm cov tshuaj no nyob rau hauv cov khoom yog heev me me, thiab lawv xyaum tsis muaj kev cuam tshuam dab tsi yog Trans Fats, thiab lawv puas phem rau koj? teebmeem kev noj qab haus huv. Tib yam tsis tuaj yeem hais rau cov khoom siv trans rog.

Puas yog cov roj trans fats tiag tiag?

Kev ci ntsa iab ntawm Trans Fats thawj zaug suav tias yog cov rog rog cuav uas muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo heev. Lawv pheej yig dua li butter, khaws cia ntev dua, thiab tso cai rov siv dua. Nws yog cov roj hydrogenated uas tau dhau los ua cov pob txha ntawm cov khoom noj ceev ceev.

Trans fats tau nyob ib ncig ntawm kaum xyoo. Nws tsuas yog nyob rau xyoo 1981 uas ib pawg kws tshawb fawb los ntawm Wales tau tawm tswv yim Hydrogenated roj thiab cov rog: muaj cov tshuaj lom neeg hloov pauv fatty acids hauv tib neeg cov ntaub so ntswg uas siv cov roj hydrogenated ua rau muaj kev pheej hmoo ntawm kab mob plawv.

Tom qab qhov no, kev tshawb fawb ntxiv tau pib, thaum lub sijhawm cov hauv qab no tau pom meej.

Lub cev saib xyuas seb cov fatty acids uas nkag mus rau nws zoo li cas.

Fatty acids yog lub tsev blocks ntawm cell membranes thiab lwm yam kab mob lom. Thiab yog hais tias lawv tsis muaj ib tug natural, tab sis ib tug artificially synthesized trans-form, ces lawv yuav tsis haum rau cov metabolism. Xws li mutants "litter" lub cev thiab cuam tshuam rau kev noj qab haus huv.

Vim li cas cov roj trans fats muaj teeb meem?

Nov yog Dab Tsi Txog Kev Tshawb Fawb Txog Niaj Hnub No Paub Dab Tsi Yog Trans Fats, thiab Lawv Puas Ua Phem Rau Koj? hais txog qhov tsis zoo ntawm cov rog trans.

1. nce qib ntawm "phem" cov roj cholesterol

Qhov no yog thawj qhov tsis txaus ntseeg hauv ntiaj teb pom los ntawm cov kws tshawb fawb. Niaj hnub no nws tau ntseeg tau tias Trans rog yog ob qho teeb meem rau koj lub plawv noj qab haus huv: kev noj cov rog trans ua rau cov roj "phem" - LDL (tsis tshua muaj lipoprotein tsawg). LDL roj cholesterol tsim nyob rau ntawm phab ntsa ntawm cov hlab ntsha thiab constricts lawv - qhov no yog li cas cov cholesterol plaques yog tsim.

Nyob rau tib lub sijhawm, cov lipoprotein ntau ntom ntom - "zoo" cov roj cholesterol, uas txo qhov kev pheej hmoo ntawm cov quav hniav, ntawm qhov tsis sib xws, txo qis.

2. Ua kom muaj kev pheej hmoo ntawm plawv nres thiab mob stroke

Qhov no yog qhov tshwm sim ntawm cov ntsiab lus ntawm cov roj cholesterol. Plaques ntawm phab ntsa ntawm cov hlab ntsha cuam tshuam cov ntshav ncig. Tsis tas li ntawd, lawv tuaj yeem tawg thiab nkag mus rau lub cev tseem ceeb, thaiv cov ntshav ntws hauv nws.

Yog tias qhov no tshwm sim hauv lub plawv cov leeg, myocardial infarction (lub plawv nres) yuav muaj. Thaum nws los txog rau lub hlwb, mob stroke tuaj yeem tshwm sim. Tag nrho cov no yog cov xwm txheej txaus ntshai heev uas tuaj yeem ua rau tuag taus.

3. Feem ntau yuav ua rau koj pheej hmoo mob ntshav qab zib

Qhov sib txuas ntawm kev noj cov rog rog thiab kev pheej hmoo ntshav qab zib tseem tsis tau paub meej. Yog li, hauv txoj kev tshawb fawb Kev Noj Qab Haus Huv, kev ua neej, thiab kev pheej hmoo ntawm hom 2 mob ntshav qab zib mellitus hauv cov poj niam, uas suav nrog ntau dua 80 txhiab tus poj niam, nws tau pom tias cov neeg uas noj cov rog ntau dhau los tsim ntshav qab zib ntau dua 40%. Tab sis lwm tus kws tshawb fawb ua tsis tiav nrhiav kev sib raug zoo.

Kev sim ntawm cov tsiaj txhu tau txais txiaj ntsig zoo sib xws. Piv txwv li, kev noj zaub mov nplua nuj nyob hauv cov rog rog tau pom tias txo qis Kev noj zaub mov trans-fatty acids hloov pauv adipocytes plasma membrane fatty acid muaj pes tsawg leeg thiab insulin rhiab heev hauv cov nas thiab hauv cov liab Trans fatty noj induces plab rog thiab kev hloov hauv insulin rhiab heev hauv cov liab insulin rhiab heev, thiab qhov no yog thawj kauj ruam ntawm kev txhim kho ntshav qab zib.

4. Ua rau kev txhim kho cov txheej txheem inflammatory

Kev mob ntev yog cuam tshuam nrog kev pheej hmoo ntawm kev tsim ntau yam kab mob: twb tau hais txog cov hlab plawv thiab ntshav qab zib, mob caj dab, metabolic syndrome thiab txawm tias mob qog noj ntshav.

Nyob rau tib lub sijhawm, ntau cov kev tshawb fawb txog kev noj cov roj ntsha trans fatty acids muaj feem xyuam rau plasma biomarkers ntawm o thiab endothelial dysfunction, noj cov zaub mov ntawm trans fatty acids thiab systemic o nyob rau hauv cov poj niam tau tsim: muaj ib tug unambiguous kev sib raug zoo ntawm kev noj cov trans fatty acids. rog thiab nce tus naj npawb ntawm cov cim ntawm o ntawm cov ntshav.

5. Muaj peev xwm ua rau mob qog noj ntshav

Nws yog qhov ua tau tias cov rog trans rog kuj ua rau muaj kev pheej hmoo ntawm kev tsim qee yam mob qog noj ntshav - tshwj xeeb tshaj yog, mob qog noj ntshav mis Kev sib piv ntawm xyoo 1997 thiab 2003 American Diabetes Association kev faib tawm ntawm cov piam thaj tsis haum: cuam tshuam rau qhov muaj feem cuam tshuam ntawm kev yoo mov tsis zoo, kab mob plawv., thiab kab mob coronary plawv hauv kev kho mob hauv zej zog. Txawm li cas los xij, tseem muaj cov ntaub ntawv tsis txaus los txhawb qhov kev xav no.

Nyob qhov twg pom cov rog rog

Trans fats tau lees paub tias muaj kev phom sij heev uas nyob rau xyoo 2018 US Food and Drug Administration (FDA) thaum kawg tau txwv qhov Kev Txiav Txim Zaum Kawg Hais Txog Ib Feem Ntawm Cov Roj Hydrogenated (Tshem Tawm Trans Fat) los ntawm kev ntxiv rau cov khoom noj.

Yog li cov neeg Asmeskas tuaj yeem xav tias muaj kev tiv thaiv ntau dua lossis tsawg dua. Txawm li cas los xij, lawv, thiab ntau dua li cov neeg nyob hauv lwm lub tebchaws, tau hais kom kho lawv cov zaub mov. Thiab tsis kam Trans rog yog ob qho teeb meem rau koj lub plawv noj qab haus huv los ntawm cov khoom hauv qab no:

• khaws cov khoom ci - khoom qab zib, yob, pies;
• khoom noj ceev, suav nrog donuts, fries, thiab breaded los yog kib nqaij qaib thiab nqaij nruab deg;
• khaws paj kws;
• khov khob noom cookie khoom, nrog rau khov pizza;
• kas fes tsis muaj mis nyuj;
• npaj ua glazes rau ncuav qab zib thiab pastries.

Cov npe no nyob deb ntawm kev ua tiav. Txhawm rau txheeb xyuas qhov kev nyab xeeb ntawm cov khoom tshwj xeeb, saib nws daim ntawv lo. Nws yeej muaj cov rog trans rog yog tias cov npe khoom xyaw muaj:

• hydrogenated roj;
• ib nrab hydrogenated roj;
• margarine;
• zaub roj;
• ua roj.

Ntau npaum li cas Trans Fats Koj tuaj yeem noj yam tsis muaj kev phom sij rau kev noj qab haus huv?

Tib neeg lub cev tsis xav tau qhov tseeb txog cov rog rog hauv cov rog trans. Lawv yog superfluous rau nws. Raws li, qhov zoo tagnrho noj txhua hnub koob tshuaj yog 0 grams.

Kev ua tiav qhov zoo tshaj plaws yog qhov nyuaj, yog li Qhov Tseeb txog cov rog trans muaj qee qhov txwv siab. Sim ua kom cov rog rog qis dua 1% ntawm tag nrho cov calories hauv koj cov zaub mov. Piv txwv li, yog tias koj tau txais 2,000 calories ib hnub twg, koj yuav tsum tau txais tsis pub ntau tshaj 20 calories los ntawm cov rog rog. Raws li qhov hnyav, qhov no tsis ntau tshaj 2 grams.
