High fructose pob kws phoov (HFCS) thiab cov suab thaj niaj hnub muaj li qub, nutritionally. Ob qho tib si yuav phem rau koj kev noj qab haus huv thaum noj ntau dhau lawm vim tias noj ntau dhau ib qho yuav ua rau koj qhov hnyav nce, thiab cov khoom qab zib tsis muaj txiaj ntsig zoo tshaj qhov calories. Qee leej neeg ntseeg tias HFCS yog qhov txaus ntshai rau koj kev noj qab haus huv dua li cov suab thaj niaj hnub, tab sis cov neeg tsis txaus siab no tsis yog los ntawm scientific findings.
Ua ntej, ib Daim Ntawv Caw Qab Zib Me
Txhua lub qauv ntawm cov piam thaj, chem npe hu ua sucrose, yog ua los ntawm ob lub piam thaj hauv qab hu ua glucose thiab fructose. Cov piam thaj yog cov piam thaj uas koj lub cev nyiam tshaj plaws rau lub zog, thiab nws pom muaj nyob rau hauv tag nrho cov khoom qab zib thiab starchy koj noj. Fructose yog lub plab tseem ceeb hauv cov txiv hmab txiv ntoo. Koj lub cev siv tau fructose ua lub zog thiab; nws cia li yuav tsum tau ua haujlwm me ntsis ntxiv.
Tag nrho cov piam thaj, seb cov piam thaj dawb piam, piam thaj xim av, piam thaj piam thaj lossis paug tib yam - ib nrab fructose thiab ib nrab piam thaj.
High fructose pob kws phoov yog ua los ntawm pob kws, thiab nws tseem ua los ntawm cov kab cij thiab cov kab mob qabzib. Tsis raws nraim li ib nrab thiab ib nrab, xws li qab zib, tab sis kaw - formulations khwv li ntawm li 42 feem pua mus rau 55 feem pua fructose. Tus nqi ntawm fructose tej zaum yuav yog "siab" piv rau cov pob kws li niaj zaus (uas yog qhov tsawg hauv fructose), tab sis yeej yog tib yam li cov piam thaj niaj hnub. Yog li, ob yam qab zib thiab HFCS muaj txog tib cov metabolism thiab cov nyhuv tib yam ntawm koj txoj kev noj qab haus huv - yog li, yog tias koj noj ntau dhau lawm, calorie ntau ntxiv tau khaws cia li roj.
Yog vim li cas HFCS Demonized?
Muaj ob peb lub hauv paus rau qhov ntawd, ob qho tib si coj nrog kev tshawb fawb tsis raws cai. Ib qho yog vim muaj kev tiv thaiv me ntsis ntawm txoj kev kawm tshawb fawb thiab lwm yam yog hais txog qhov tsis sib haum xeeb thiab ua rau.
Ua ntej, lub fructose conflation. Cov kev tshawb fawb tau ua nrog cov tsiaj txhu kuaj pom cov noj cov zaub mov muaj zog hauv fructose tuaj yeem ua rau hnyav nce ntxiv, insulin tsis kam, ntshav siab thiab siab triglycerides - txhua yam phem.
Txij li thaum "fructose" suab ntau heev li "siab fructose pob kws phoov" thiab tsis muaj dab tsi zoo li "qab zib," qee cov neeg ua rau ob leeg txiav txim siab thiab txiav txim siab HFCS yog qhov txaus ntshai, tiam sis tsis muaj suab thaj tsis zoo li.
Nws muaj peev xwm ua kom muaj feem ntau ntawm koj cov calorie los ntawm fructose txhua hnub yuav ua rau hnyav nce ntau dua cov calorie uas tau siv los ntawm lwm qhov chaw qab zib - yam tsawg kawg yog tias koj yog ib tus nas (cov kev tshawb fawb ntawm tib neeg tsis tau thab li qhov thov). Tab sis, yog tias koj tsuas noj ntau fructose feem ntau - vim koj noj zaub mov ntau dhau? Thiab ua li cas yog tias ntau qhov fructose tau los ntawm HFCS vim nws tshwm sim los ua ib qho khoom ua ke? Qhov ntawd coj kuv mus rau lwm qhov thib ob rau kev ua phem rau HFCS, kev ntxhov siab ntawm qhov ua rau thiab sib txheeb.
High fructose pob kws phoov yog pheej yig dua cov piam thaj, yog li nws siv los ua cov khoom noj khoom haus thiab dej haus tau ntau xyoo dhau los lawm. Thaum tib lub sijhawm ntawd, cov kev rog, cov kab mob plawv, thiab kab mob ntshav qab zib hom II kuj nce mus hauv Tebchaws Asmeskas thiab qee leej neeg ua txhaum xws li nce siab ntawm HFCS noj.
Muaj caloric intake los ntawm HFCS tej zaum yuav yog ib feem ntawm qhov teeb meem - tsis vim HFCS yog kev mob nkeeg - tab sis vim tias cov neeg Mis Kas tau nce lawv cov calorie ntau ntau.
Nyob rau hauv rooj plaub no, HFCS tsuas yog ib qho kev sib txawv xwb, thiab tsis muaj qhov laj thawj ntseeg tau tias qhov ua kom qab zib raws li qhov khoom yuav ua rau muaj qhov txawv.
Zaub mov sib ntaus - Leej twg yog tus khiav tau?
Muaj tsis yog ib tug yeej nyob ntawm no - HFCS thiab tsis tu ncua qab zib yog ib qho zoo me ntsis thiab ob qho tib si yog tias koj noj ntau dhau - tab sis txog kev sib npaug; ib tug tsis mob heev dua lwm tus. Ntau ntau qab zib los yog HFCS yuav muaj kev cuam tshuam zoo rau lub cev los ntawm kev nce ntshav ntawm cov ntshav qab zib zoo li triglycerides thiab tuaj yeem pab ua kom hnyav nce thaum koj haus ntau dhau.
Npaum li cas yog ntau dhau lawm? Qhov ntawd yog nyob ntawm koj cov kev xav tau txhua hnub, tab sis koj muaj peev xwm muaj txog li ntawm 200 mus rau 200 tus neeg caloric ntau ntau nyob rau ob peb grams qab zib los yog HFCS txhua hnub.
