phosphates ua dab tsi rau koj lub cev?
Phosphates yog cov zaub mov tseem ceeb uas ua lub luag haujlwm tseem ceeb hauv ntau yam txheej txheem lom neeg hauv tib neeg lub cev. Los ntawm kev tsim cov pob txha thiab cov hniav mus rau kev tsim lub zog ntawm qib cellular, phosphates muaj nyob hauv ntau thoob plaws hauv peb lub cev. Txawm li cas los xij, zoo li txhua yam khoom noj, kev noj ntau dhau ntawm phosphates tuaj yeem ua rau muaj kev phom sij rau peb txoj kev noj qab haus huv. Hauv tsab xov xwm no, peb yuav tshawb xyuas cov haujlwm ntawm phosphates, lawv cov peev txheej, pom zoo kom noj txhua hnub, thiab muaj peev xwm noj qab haus huv cuam tshuam nrog lawv cov kev noj ntau dhau.
Qhov tseem ceeb ntawm phosphates hauv lub cev
Phosphates feem ntau paub txog lawv lub luag haujlwm hauv kev tsim thiab kho cov pob txha noj qab haus huv thiab cov hniav. Ua ke nrog calcium, phosphates ua ib feem tseem ceeb ntawm cov ntxhia hauv peb lub cev pob txha. Lawv muab cov qauv kev txhawb nqa thiab pab tswj cov pob txha ceev, lub zog, thiab kev ncaj ncees tag nrho. Phosphates tseem ua lub luag haujlwm tseem ceeb hauv kev tsim cov adenosine triphosphate (ATP), thawj lub zog txiaj ntawm peb lub hlwb.
Ntxiv mus, phosphates yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm peb cov hlwb thiab cov ntaub so ntswg. Lawv koom nrog ntau yam txheej txheem ntawm tes, suav nrog DNA synthesis, cellular signaling, thiab kev tswj hwm ntawm kev ua enzyme. Phosphates tseem yog ib qho tseem ceeb ntawm cov cell membranes, qhov uas lawv pab txhawb rau lawv cov qauv kev ncaj ncees thiab pab txhawb kev thauj ntawm cov molecules hla lub membrane.
Ntxiv nrog rau lawv cov haujlwm ntawm tes, phosphates tau koom nrog hauv kev tswj hwm pH thiab cov kua dej sib npaug hauv peb lub cev. Lawv ua raws li buffers los tswj cov kua qaub-puag sib npaug thiab pab tswj cov osmotic siab thoob plaws cell membranes.
Qhov chaw ntawm phosphates
Phosphates feem ntau pom nyob rau hauv ntau yam khoom noj. Cov no suav nrog cov khoom noj siv mis, xws li mis nyuj, cheese, thiab yogurt, uas muaj calcium phosphate nplua nuj. Nqaij, nqaij qaib, thiab ntses kuj muaj cov phosphates loj heev. Lwm cov khoom noj muaj xws li legumes, txiv ntseej, tag nrho cov nplej, thiab qee yam zaub, xws li broccoli thiab spinach.
Kev lag luam zaub mov kuj tseem siv phosphates ua zaub mov additives hauv ntau yam khoom noj. Cov additives no pab ntau lub hom phiaj, nrog rau kev txhim kho kev ntxhib los mos, txhim kho cov dej noo, thiab tiv thaiv kev lwj. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev noj ntau dhau ntawm cov zaub mov ua tiav, uas feem ntau muaj phosphates siab, tuaj yeem ua rau lub cev tsis sib xws.
Pom zoo noj txhua hnub
Cov kev pom zoo txhua hnub ntawm phosphates sib txawv nyob ntawm seb muaj hnub nyoog, poj niam txiv neej, thiab kev noj qab haus huv tshwj xeeb. Feem ntau, kev noj zaub mov kom tsawg (DRI) rau phosphorus, qhov taw qhia ntawm phosphates, yog raws li hauv qab no:
- Me nyuam mos (0-6 hli): 100 mg/hnub
- Me nyuam mos (7-12 hli): 275 mg/hnub
- Cov menyuam yaus (1-3 xyoo): 460 mg / hnub
- Cov menyuam yaus (4-8 xyoo): 500 mg / hnub
- Cov menyuam yaus (9-18 xyoo): 1,250 mg / hnub
- Cov neeg laus (19 xyoo thiab laus dua): 700 mg / hnub
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov txiaj ntsig no tuaj yeem sib txawv me ntsis raws li cov txheej txheem kev noj haus hauv cheeb tsam thiab cov kev xav tau ntawm tus kheej. Cov poj niam cev xeeb tub thiab pub niam mis yuav xav tau cov phosphates ntau dua los txhawb lawv tus kheej kev noj qab haus huv thiab kev loj hlob ntawm lawv tus menyuam.
Kev noj qab haus huv txaus ntshai cuam tshuam nrog kev noj phosphate ntau dhau
Thaum phosphates yog qhov tseem ceeb rau peb lub cev kev ua haujlwm zoo, kev noj ntau dhau tuaj yeem ua rau muaj teeb meem kev noj qab haus huv. Qib siab ntawm phosphates hauv cov ntshav, hu ua hyperphosphatemia, tuaj yeem muaj ntau yam teebmeem.
Ib qho kev pheej hmoo ntawm kev noj qab haus huv cuam tshuam nrog kev noj phosphate ntau dhau yog kev txhim kho ntawm lub raum pob zeb. Thaum cov phosphate qib siab, lawv tuaj yeem ua ke nrog calcium hauv cov zis thiab tsim cov pob zeb, uas ua rau tsim cov pob zeb rau lub raum. Cov pob zeb no tuaj yeem ua rau mob hnyav thiab tsis xis nyob thiab yuav xav tau kev pab kho mob kom tshem tawm.
Hyperphosphatemia kuj tseem tuaj yeem ua rau kev txhim kho ntawm cov kab mob plawv. Thaum cov qib phosphate nce siab, nws tuaj yeem ua rau vascular calcification, txheej txheem uas calcium thiab phosphate accumulates hauv cov phab ntsa hlab ntsha. Qhov calcification no tuaj yeem ua rau cov ntshav tsis txaus thiab ua rau muaj kev pheej hmoo ntawm plawv nres, mob stroke, thiab lwm yam teeb meem plawv.
Tsis tas li ntawd, kev noj phosphate ntau dhau tuaj yeem cuam tshuam nrog kev nqus ntawm lwm cov zaub mov tseem ceeb, xws li calcium, hlau, thiab magnesium. Qhov no tuaj yeem cuam tshuam cov ntxhia hauv lub cev thiab ua rau muaj qhov tsis txaus ntawm cov as-ham.
Tiv thaiv kom tsis txhob muaj phosphate ntau dhau
Txhawm rau tiv thaiv kev noj cov phosphate ntau dhau, nws yog ib qho tseem ceeb uas yuav tsum tau noj zaub mov kom zoo uas suav nrog ntau yam khoom noj muaj txiaj ntsig. Tsis yog kev cia siab rau cov khoom noj uas tau ua tiav ntau uas yuav muaj cov phosphates siab, tsom rau tag nrho cov khoom noj xws li txiv hmab txiv ntoo, zaub, lean proteins, whole grains, thiab cov khoom noj siv mis hauv nruab nrab.
Kev nyeem cov ntawv qhia zaub mov tseem tuaj yeem pab txheeb xyuas cov phosphate additives hauv cov zaub mov ua tiav. Nrhiav cov khoom xyaw xws li sodium phosphate, calcium phosphate, lossis potassium phosphate, uas qhia tias muaj cov phosphates ntxiv. Tsis tas li ntawd, kev xyaum tswj hwm thiab kev ua kom zoo yog qhov tseem ceeb hauv kev tswj hwm kev noj qab haus huv ntawm cov as-ham, suav nrog phosphates, hauv lub cev.
Xaus
Phosphates yog cov zaub mov tseem ceeb uas ua rau muaj ntau yam txheej txheem physiological hauv peb lub cev. Los ntawm kev tsim cov pob txha thiab lub zog tsim tawm mus rau lub zog ntawm tes thiab kev tswj hwm pH, phosphates ua lub luag haujlwm tseem ceeb hauv kev tswj hwm peb kev noj qab haus huv tag nrho. Txawm li cas los xij, kev noj phosphate ntau dhau tuaj yeem ua rau muaj kev cuam tshuam tsis zoo, suav nrog kev tsim cov pob zeb hauv lub raum, mob plawv, thiab cov ntxhia tsis txaus.
Txhawm rau kom muaj kev noj qab haus huv ntawm phosphates, nws yog ib qho tseem ceeb uas yuav tsum tau noj cov zaub mov muaj txiaj ntsig uas suav nrog ntau yam khoom noj. Los ntawm kev nco qab txog cov khoom noj uas yuav muaj cov phosphates ntxiv thiab xyaum ua kom zoo, peb tuaj yeem tswj tau qhov zoo tshaj plaws ntawm phosphates hauv peb lub cev thiab txhawb peb txoj kev noj qab haus huv tag nrho.
