Txhua tus neeg yuav tsum ua raws li qee yam kev noj haus. Koj yuav tsum tsis txhob noj zaub mov tas li thiab tsis quav ntsej zaub thiab txiv hmab txiv ntoo. Kev saib xyuas tshwj xeeb yuav tsum tau them rau cov zaub mov muaj protein, vim tias tsis muaj cov amino acids hauv cov zaub mov ua rau muaj teeb meem ntau rau tib neeg lub cev.

YLub luag haujlwm ntawm cov proteins

Proteins yog lub hauv paus ntawm cov hlwb ntawm tib neeg lub cev. Lawv tsis tsuas yog ua cov txheej txheem kev ua haujlwm, tab sis kuj yog cov enzymes lossis cov khoom siv roj ntsha uas ua kom cov tshuaj tiv thaiv. Thiab nrog tsis muaj carbohydrates lossis rog, lawv ua haujlwm ua lub zog. Tsis tas li ntawd, cov tshuaj tiv thaiv thiab qee cov tshuaj hormones yog cov proteins.

Peb txhua tus paub tias cov protein molecules muaj cov amino acids uas tau teem rau hauv ib ntu. Tab sis tsis tshua muaj leej twg nco qab tias lawv tau muab faib ua ob pawg: hloov tau thiab hloov tsis tau.

Yam amino acids hu ua qhov tseem ceeb?

Yog tib neeg lub cev tuaj yeem tsim cov amino acids tseem ceeb ntawm nws tus kheej, ces nws yuav tsis ua haujlwm nrog cov amino acids tseem ceeb. Lawv yuav tsum tau noj nrog zaub mov yam tsis tau poob, vim tias lawv tsis ua raukom tsis muaj zog nco thiab txo kev tiv thaiv. Muaj yim cov amino acids: isoleucine, valine, leucine, methionine, threonine, tryptophan, lysine thiab phenylalanine.

Cov zaub mov twg muaj cov amino acids tseem ceeb?

Peb txhua tus paub zoo tias cov khoom noj tsiaj muaj protein ntau: nqaij (me nyuam yaj, nqaij nyug, nqaij npuas, nqaij qaib), ntses (cod, pike perch), qe, mis nyuj thiab ntau hom cheese. Tab sis li cas txog cov chaw cog? Tau kawg, legumes nyob thawj qhov chaw ntawm cov ntsiab lus ntawm cov amino acids tseem ceeb. Ntawm no yog ib daim ntawv teev cov legumes:

• taum;
• lentils;
• peas;
• taum;
• soy.

taum yog ib qho tseem ceeb ntawm tib neeg txij thaum ub. Thiab tsis nyob rau hauv vain! Tsis muaj qhov yuav tsum tau sib cav txog lawv cov txiaj ntsig, vim tias cov txiaj ntsig ntawm cov khoom no ntawm lub cev yog qhov loj heev. Legumes pab ntxuav cov ntshav, ntxiv dag zog rau cov plaub hau, thiab txhim kho kev zom zaub mov. Thiab nyob rau hauv cov nqe lus ntawm cov ntsiab lus protein, lawv yog ib qho nyuaj rau inferior rau nqaij. Tsev neeg ntawm cov nroj tsuag no tam sim no tau dhau los ua ib qho tseem ceeb hauv kev noj haus, vim kev tshawb fawb twb muaj cov ntaub ntawv ntau ntawm lawv cov txiaj ntsig.

Hauv qhov piv txwv ntawm kev noj zaub mov zoo txhua hnub, legumes yuav tsum yog 8-10% txhawm rau kom cov zaub protein ua kom tiav thiab muab cov txheej txheem ua neej tsim nyog. Piv txwv li, noj peas, taum lossis lentils normalizes ntshav qab zib thiab, ntxiv rau, ntxiv dag zog rau lub cev thiab lub paj hlwb.

Tus qhab nia amino acid yog dab tsi?

Rau sawv dawsNws paub tias txhua yam khoom muaj nws cov khoom noj muaj txiaj ntsig. Nws yog tus cwj pwm los ntawm qhov zoo ntawm cov proteins uas muaj nyob hauv nws. Qhov zoo ntawm cov khoom noj khoom haus tseem ceeb no yog vim muaj cov amino acids tseem ceeb hauv nws, lawv degradability thiab piv rau lwm yam, tsis tseem ceeb, amino acids.

Nyob rau xyoo 1973, qhov taw qhia ntawm cov nqi roj ntsha ntawm cov protein tau qhia - amino acid qhab nia (AC). Kev paub txog tus nqi ntawm qhov ntsuas no yog qhov tseem ceeb heev, vim nws qhia txog cov protein tau txais, cov amino acids meej dua, thiab yuav pab suav cov khoom noj uas yuav tsum tau noj kom cov zaub mov tiav thiab muaj tag nrho yim cov amino acids tseem ceeb.. Lawv qhov kev xav tau txhua hnub yog qhia hauv cov lus hauv qab no (g rau 100 g ntawm cov protein).

Amino acid	Txoj kev ntseeg siab
Isoleucine	1,8
Valine	1,8
Leucine	2,5
Methionine + Cystine	2,4
Threonine	1,3
Tryptophan	0, 65
Lysine	2, 2
Phenylalanine + Tyrosine	2,5

Yog li, cov qhab nia amino acid yog ib txoj hauv kev los txiav txim siab qhov zoo ntawm cov protein los ntawm kev sib piv cov amino acids hauv cov khoom kuaj nrog cov protein "zoo tagnrho". Ib qho protein zoo tshaj plaws yog cov protein ntau uas muaj qhov sib npaug ntawm cov amino acid muaj pes tsawg leeg.

Yog tias tus nqi ntawm qhov piv txwv no tsawg dua ib qho, ces cov protein tsis raug. Kom tau ib qho tiavprotein, nws yog ib qho tsim nyog los muab cov zaub mov kom tag nrho cov amino acid no kwv yees sib npaug rau nws cov kev xav tau txhua hnub.

Yuav ua li cas kom raug?

txhawm rau xam cov qhab nia amino acid, koj yuav tsum pom qhov loj ntawm tag nrho cov protein hauv 100 grams ntawm cov khoom no, siv lub rooj ntawm nws cov tshuaj muaj pes tsawg leeg. Tom qab ntawd nrhiav cov ntsiab lus ntawm qhov xav tau amino acid (feem ntau nws tau muab hauv mg, tab sis peb xav tau hauv g; txij li 1000 mg yog 1 g, tsuas yog faib tus lej no los ntawm ib txhiab) hauv 100 g ntawm cov khoom. Txhawm rau xam AC, koj yuav tsum xam tus nqi no rau 100 g ntawm cov protein.

Koj yuav tsum ua tus qauv:

Ntau ntawm tag nrho cov protein ib 100g zaub mov / 100g protein=Tus nqi ntawm cov amino acid xav tau rau 100g zaub mov / X (ntau npaum li cas ntawm cov amino acid ib 100g protein zaub mov)

Tau pom X, peb mus rau kev suav ntawm AC. Txhawm rau ua qhov no, koj yuav tsum faib cov txiaj ntsig tau los ntawm kev siv tus nqi ntawm cov amino acid no. Nws tau qhia hauv cov lus hauv qab no (g rau 100 g ntawm cov protein).

Amino acid	Reference nqi
Isoleucine	4,0
Valine	5,0
Leucine	7,0
Methionine + Cystine	3,5
Threonine	4,0
Tryptophan	1,0
Lysine	5, 5
Phenylalanine + Tyrosine	6,0

Piv txwv: xam AC ntawm valine hauv rog kefir.

Cov protein ntau hauv 100 g ntawm kefir yog 2.8 g. Cov ntsiab lus ntawm valine hauv cov khoom no yog 135mg ib 100g.

Yog li ntawd, raws li tus qauv:

1) 2.8g - 0.135g;

2) 100 g - X g;

3) X=0, 135100/2, 8=4, 8g.

Faib tus nqi tau los ntawm tus nqi ntawm lub rooj: 5.0 g / 4.8 g=0.96.

Yog li, 0, 04, lossis 4% ntawm valine tseem ploj los ntawm cov qauv xav tau hauv kev sib piv nrog nws cov lus siv (xav tau ntawm peb lub cev) tus nqi. Nov yog qhov koj tuaj yeem suav cov qhab nia amino acid.
