Yuav ua li cas yog carbohydrates?

Nws yog tsis muaj daim card uas muaj, txawm lub gastronomically sophisticated thiab kab txawv khoom noj khoom haus yuav tsum decomposed rau hauv nws cov feem hais, lub npe ntawm uas macronutrients. Sau lawv heev luv luv thiab zoo paub:

• proteins;
• cov rog;
• carbohydrates.

Nyob rau hauv tas li ntawd, txhua yam khoom nyob rau hauv sib txawv proportions muaj dej, vitamins thiab ib txoj lw ntsiab. Nws yog nyob rau hauv no pob tawg lawm saib ntawm cov zaub mov absorbed los ntawm lub cev. Txhua zaub mov kom tsawg, nyob ntawm seb qhov feem pua muaj pes tsawg leeg ntawm macronutrients, muaj ib tug txawv ntxim rau cov tib neeg noj qab haus huv. Qhov no yog hais tias txhua "cib" nws muaj nws muaj nuj nqi thiab pab txawv lub hom phiaj. Qhov tsab xov xwm yuav tsum tau tham nyob rau hauv ntau yam carbohydrates thiab lawv muaj nuj nqi.

Feem ntau cov khoom uas muaj zog tus nqi txuam nrog calorie ntau ntau. Tsis ntev los no fashionable rau raug tshem tawm los ntawm cov khoom noj carbohydrate-muaj zaub mov, raws li nws yog ntseeg hais tias txoj kev ntawm calorie ntau ntau kom tsawg yog txo. Tseeb nyob rau hauv no mus kom ze, ntawm chav kawm. Tshwj xeeb tshaj yog yog hais tias koj muaj kev ua kis las. Txawm li cas los, ua ntej tej yam uas ua ntej.

Yog li ntawd yog dab tsi carbohydrates?

Lub ntsiab muaj nuj nqi ntawm cov macronutrients - lub zog. Raws li ib yam ntawm cov roj teeb rau hauv lub cev, carbohydrates pab txhawb livelihoods, vim lub zog ntawm lawv cov cleavage yog nqa tawm kev ua hauj lwm ntawm tag nrho cov lub cev. Nws yog lub npe hu hais tias cleavage loo 1 g carbohydrate 4 kcal lub cev. Cov nqi qub nkag mus rau hauv lub cev thiab nyob rau hauv lub cleavage ntawm 1 g ntawm roj. Txawm li cas los, lub splitting ntawm ntev chains ntawm monosaccharides derivatives siv ntau tsawg zog, thiab yog li ntawd lub cev yog yooj yim mus rau "hlawv" 1 g carbohydrate, 1 g roj tshaj los ntawm lub zeem cia.

Carbohydrates, nyob ntawm seb lub molecular qauv los, nyob rau hauv lwm yam lus, qhov ntev ntawm lub molecular saw, yog muab faib ua tej yam yooj yim thiab complex.

Yuav ua li cas yog carbohydrates yooj yim?

Science, muaj ob hom ntawm monosaccharides thiab disaccharides. Ntawm cov monosaccharides ntau heev thiab tshwm sim nyob rau hauv free daim ntawv nyob rau hauv cov xwm - piam thaj thiab fructose. Lawv muaj nyob rau hauv tshiab kua, txiv hmab txiv ntoo. Cov saw ntawm monosaccharides, raws li tau pom los ntawm lub npe - tus feem ntau yooj yim, uas muaj txhawb mus rau lawv sai haum los ntawm lub cev. Formula disaccharides (sucrose, maltose, lactose) - saw seem ntawm ob peb monosaccharides. Disaccharides muaj nyob rau hauv khoom noj siv mis (lactose), kab tsib (sucrose) thiab nyob rau hauv ib co cereals (maltose).

Yuav ua li cas yog txoj carbohydrates?

Lwm yam -polisaharidy lawv lub npe, lawv tseem muaj li ntawm ob peb txhiab monosaccharide residues, uas yog, muaj ib tug ntev thiab branching saw ntawm ntau tshaj yooj yim carbohydrates. Qhov zoo tshaj plaws lub npe hu cov neeg sawv cev ntawm no pab pawg neeg yog ib tug pectin, cellulose, starch thiab glycogen. Carbohydrates yog cov pab pawg neeg nyob rau hauv nws thawj daim ntawv yog tsis absorbed los ntawm lub cev. Splitting lawv mus rau hauv tej yam yooj yim thiab yooj yim digestible daim ntawv yuav tsum tau tseem ceeb cov nqi zog. Ib txhia hom (fiber) yog tsis absorbed ntawm tag nrho cov. Nws yuav pab tau siv rau lawv raws li ib tug stimulator ntawm tus mob huam ua si thiab ntxuav ntawm toxins. Tsis tas li ntawd, glycogen, xws li ib lub tsev khoom siv rau lub cev (daim siab, mob).

Thaum peb pom seb zoo li cas cov carbohydrates, nws yuav ua rau kev txiav txim zoo rau rov qab mus rau rau lo lus nug ntawm lawv usefulness mus rau lub cev. Nws yog pom tseeb tias lawv txoj ntaub ntawv yog pab tau thiab txawm tsim nyog rau lub cev kom ua hauj lwm kom zoo vim lub fact tias lawv nqa tawm cov kev siv thiab noj haus muaj nuj nqi.

Vim lub fact tias polysaccharides phua uas muaj zog noj thiab nqis ntau maj mam, lawv yuav tsis yog cia li muaj roj vim hais tias tsuas yog tsis muaj lub sij hawm. Monosaccharides, on qhov tsis tooj, kev kawm sai npaum li cas thiab acting ncaj qha rau hauv cov ntshav, ua rau cov thiaj li hu ua "carbohydrate leap" uas yog sharply nce lub zog. Lawv ntev siv, nyob rau hauv lub qhaj ntawv ntawm siab zog noj, ua rau ua ntawm carbohydrates thiab lawv txuam nrog rau hauv daim ntawv ntawm cov rog.

Qhov ntawd yog qhov carbohydrates, koj yuav tsum paub kom lawv muaj khoom noj kom zoo. Cov kev siv ntawm tej yam yooj yim thiab complex nrhiav yuav tsum tau rau lub cev, txwv tsis pub tus dab (xws li kev puas hlwb) slowing, tshwm sim nkees thiab apathy.
