Kev tshawb fawb hauv nas qhia tau hais tias kev noj cov protein ntau dhau uas muaj cov amino acids ntau (BCAAs) ntev ntev tuaj yeem ua rau tsis sib npaug ntawm cov amino acids thiab tswj kev noj mov. Qhov no cuam tshuam rau kev noj qab haus huv ntawm lub cev thiab ua rau lub neej luv dua.
Kev noj zaub mov zoo yuav tsum muaj cov macronutrients sib npaug ( protein , carbohydrate thiab rog), fiber, vitamins thiab minerals. Muaj ntau txoj kev tshawb fawb tau tsom mus rau qhov tseem ceeb ntawm kev noj zaub mov protein , rog thiab carbohydrates kom muaj txiaj ntsig zoo rau peb txoj kev noj qab haus huv . Yog tias tsis muaj qhov sib npaug ntawm cov macronutrients no hauv peb cov zaub mov noj, peb yuav paub tias yuav ua rau muaj kev noj qab haus huv tsis zoo.
Cov protein yog ib qho macromolecule nyuaj uas muaj cov amino acids. Muaj 20 amino acids, uas cuaj yog qhov tseem ceeb uas tuaj yeem ua rau lub cev tsim 11 seem. Cov amino acids branched-chain (BCAAs) yog ua los ntawm peb ntawm cuaj cov amino acids tseem ceeb - leucine, isoleucine thiab valine. Cov leeg, lub hauv paus tseem ceeb ntawm lub cev feem ntau yog tsim los ntawm cov protein . BCAAs raug rhuav tshem hauv cov leeg, muaj cov calories ntau thiab noj rau cov leeg nqaij uas lawv muab. BCAAs muaj nyob rau hauv cov khoom noj protein xws li nqaij liab, qe, taum, lentils, soy protein thiab lwm yam thiab kuj feem ntau muaj nyob rau hauv cov tshuaj protein bodybuilding noj tom qab kev tawm dag zog lossis kev tawm dag zog. Tsis muaj kev tshawb fawb txaus tau ua los ntsuas cov teebmeem tsis zoo ntawm kev noj BCAAs ntau dhau. Lawv cov teebmeem mus sij hawm ntev rau kev noj qab haus huv thiab lub neej tseem tsis tau paub.
Hauv kev tshawb fawb luam tawm hauv Nature Metabolism thaum Lub Plaub Hlis 29, 2019, cov kws tshawb fawb tau tsom mus txiav txim siab seb kev siv BCAAs ntev ntev yuav muaj feem cuam tshuam li cas rau kev noj qab haus huv thiab lub neej. Hauv lawv cov kev sim ua rau nas, cov tsiaj noj rau lawv lub neej tag nrho (a) cov BCAAs ib txwm muaj xws li 200 feem pua (b) ib nrab ntawm cov nyiaj xws li 50 feem pua lossis (c) ib feem tsib ntawm cov nyiaj xws li 20 feem pua. Nrog rau, nas tau muab isocaloric, cov nyiaj ruaj khov ntawm lwm cov macronutrients - carbohydrates thiab rog. Kev noj ntau dhau ntawm BCAAs ua rau muaj ntau ntawm BCAAs hauv cov ntshav thiab qhov no zoo li thaiv kev thauj mus los ntawm lwm yam tsis yog BCAA tryptophan mus rau lub hlwb. Tryptophan yog tib qho ua ntej ntawm cov tshuaj hormones serotonin uas muaj cov teebmeem zoo rau kev xav thiab yog li ntawd tseem ceeb rau kev txhawb nqa kev pw tsaug zog. Thaum tryptophan raug thaiv los ntawm kev ncav cuag lub hlwb, qhov no ua rau cov theem serotonin hauv nruab nrab poob qis ua rau noj ntau dhau (lossis hyperphagia) hauv nas feem ntau vim yog qhov tsis sib npaug ntawm cov amino acid los ntawm kev nce ntxiv ntawm BCAAs: non-BCAAs. Yog li, cov nas noj zaub mov ntau dhau (ob qho tib si tag nrho lub zog thiab BCAAs) - tseem hu ua kev pub mis rau lub cev - ua rau lub cev hnyav thiab rog ntau ntxiv ua rau lawv rog dhau thiab ua rau lawv lub neej luv dua.
Txoj kev tshawb no qhia tau hais tias kev sib raug zoo ntawm qib nce ntawm BCAAs hauv cov ntshav thiab cov txiaj ntsig kev noj qab haus huv tsis zoo li tsis cuam tshuam rau qhov BCAA toxicity lossis kev puas tsuaj. Qhov kev sib raug zoo yog vim muaj kev sib cuam tshuam ntawm BCAAs thiab lwm yam amino acids tseem ceeb thiab qhov no yog qhov ua rau hyperphagia heev. Cov txiaj ntsig tau qhia tias noj cov khoom noj ntau ntawm BCAAs rau lub sijhawm ntev nrog rau cov nyiaj tas li ntawm lwm cov macronutrients tuaj yeem ua rau hyperphagia uas tau tsav los ntawm cov amino acid tsis txaus thiab cuam tshuam rau kev noj qab haus huv hauv metabolic thiab txo txoj sia. Txawm hais tias muaj ntau ntawm BCAAs tuaj yeem tshwm sim hauv ob qho tib si metabolically noj qab haus huv thiab tsis noj qab haus huv nas. Yog li, BCAA ib leeg tsis tuaj yeem yog biomarker nkaus xwb rau kev noj qab haus huv metabolic.
Txoj kev tshawb fawb tam sim no rov tsim dua qhov tseem ceeb ntawm kev noj zaub mov kom zoo uas muaj ntau yam macronutrients, fibers, vitamins thiab minerals thiab txwv tsis pub noj cov tshuaj uas tsis xav tau.
