Nitrates sib haum xeeb tshwm sim nyob rau hauv qhov thiab nws yog tsis yooj yim sua kom tau tshem ntawm lawv. Qhov no yog ib qho tseem ceeb ntawm cov khoom noj khoom haus nitrogen rau cov nroj tsuag, tsis muaj cov protein synthesis tsis yooj yim sua. Txawm hais tias chiv tsis siv nyob rau hauv tag nrho, lawv tseem ua nitrites, thiab nyob rau hauv lub kawg tshwm sim lawv tig mus rau ammonia (lub ntsiab zaub ntawm cov nroj tsuag).
Yog li, qhov muaj cov nitrates tsis yog li ntawd, tab sis ib qho overabundance yuav ua rau muaj teeb meem loj heev. Nyob rau hauv ib hnub twg ib tug neeg tau pub 300-350 mg ntawm nitrates. Yog li no, tsis txhob maj maj maj nrog cov zaub thiab txiv hmab txiv ntoo, thiab qee zaum ua raws li cov lus qhia ntawm cov kws tshwj xeeb.

Nitrates nkag peb lub cev tsis tsuas yog cog nrog zaub mov, tab sis kuj nrog nqaij, dej thiab tshuaj. Hauv cov ntses thiab nqaij cov khoom noj lawv muaj tsawg. Tab sis nyob rau hauv cov khoom tiav los khaws cia thiab txhim kho qhov saj ntawm Chemistry, tag nrho cov tuam txhab ntxiv. Nitrates yog nplua nuj nyob hauv av, luam yeeb, txawm lub cev xwb tuaj yeem tsim lawv nrog ib hom metabolism.
Teeb meem mus rau tib neeg lub cev nitrates heev ho:
Qhov tshwm sim ntawm lawv cov ua - nitrites nyob rau hauv kev sib raug zoo nrog hemoglobin daim ntawv methemoglobin, uas tsis tuaj yeem saturate hlwb nrog oxygen. Yog li ntawd, cov kua qaub qis ntawm tus kab mob lactic increases thiab cov protein nyob hauv cov ntshav tsawg. Qhov no muaj tseeb rau cov me nyuam mos, lawv lub tshuab tseem tsis tau ua sai sai ua rau lub pob zeb methemoglobin nyob hauv ib txwm muaj hemoglobin.
Lawv txo cov vitamins nyob rau hauv cov zaub mov thiab cuam tshuam rau cov metabolism.
Nrog lub caij nyoog nkag, muaj ib qho kev tsis txaus siab ntawm iodine thiab nce hauv cov thyroid caj pas.
Nws yog pov thawj tias lawv tuaj yeem ua rau kev loj hlob ntawm cov qog nyob rau hauv txoj hnyuv.
Ua rau muaj kev tsim txom ib puag ncig hauv cov hnyuv, uas nyob rau hauv lem tawm qhia co toxins thiab tshuaj lom tag nrho lub cev.
Koj tuaj yeem tiv thaiv koj tus kheej los ntawm nitrates los yog tiv thaiv koj tus kheej los ntawm lawv cov teebmeem? Ua ntej tshaj plaws, nws yog qhov zoo tsim nyog paub qhov twg qhov "yeeb ncuab" yog thiab yog tias ua tau mus dhau qhov ntawd.
Feem ntau ntawm cov nitrates hauv daim tawv nqaij ntawm zaub thiab txiv hmab txiv ntoo.
Cov txiv hmab txiv ntoo uas tsis tau hlawv cov txiv hmab txiv ntoo tseem muaj ntau dua nyob hauv nitrates.
Lawv muaj nyob rau hauv stems. Nyob ze ntawm lub hauv paus. Yog li ntawd, siv celery, dill, lwm yam zoo li, nws yog zoo dua los siv nplooj. Tib yam siv rau dawb cabbage, nyob rau hauv lub hauv paus ntawm uas lawv accumulate.
Lub hauv paus ntawm lub carrot muaj ntau nitrates tshaj li saum npoo.
Ib tug loj concentration ntawm nitrates nyob rau hauv lub immature pulp ntawm watermelon thiab melon ze ntawm crust, lub Upper nyob ib sab mus rau peduncle ntawm zucchini, eggplant, thiab squash.
Nyob rau hauv cucumbers, radish, beets lawv sau nyob rau ob qho tag nrho, uas yog zoo tshaj tawm.
Yog hais tias cov txiv hmab txiv ntoo tsis tau muab cia rau hauv lub tub yees, cov nitrates yuav hloov dua siab tshiab rau nitrite ntau.
Tom qab ntxuav zaub lossis txiv hmab txiv ntoo kom zoo thiab ua rau lawv nyob hauv dej ib ntus, koj yuav txo cov khoom ntawm cov teeb meem tshuaj los ntawm 20%.
Thaum noj cov zaub nyoos, nws yuav tsum nco ntsoov tias qhov teeb meem loj hlob sai sai nyob rau hauv qaub cream thiab mayonnaise, thiab nrog rau qhov kub hloov tas li. Li ntawd, nws yog qhov zoo dua rau noj txhua yam freshly npaj.
Ua cov pickles, kev txuag thiab pickling, koj yuav tsum noj nws tag nrho tom qab 15 hnub, txij li thaum thawj zaug, qhov ntau tshaj ntawm nitrates tso tawm.
Siv cov lus pom zoo no, koj tuaj yeem tiv thaiv me ntsis ntawm qhov chaw muaj teeb meem. Tsis txhob hnov qab tias dhau kev tawm tsam nrog cov tshuaj no tuaj yeem tshem cov vitamins ntawm cov zaub mov. Txhua yam yuav tsum tau txav raws li qhov tsim nyog thiab cov txiaj ntsim yuav ua rau nws tus kheej pov thawj.
