Potassium: mihla izinga ukusetyenziswa

Injongo yale iphepha ukufunda indima kwiiseli engundoqo imichiza - potassium - in nethe komzimba womntu. Kwakhona sifumanisa ukuba izinga ngemihla potassium nezinki iza kuqinisekisa ukusebenza kwawo onke amalungu abalulekileyo kunye neenkqubo komzimba umzimba.

Eziphilayo, iingxaki zawo namathemba

Kubomi bemihla ngemihla, amaxesha amaninzi ukusebenzisa amabinzana afana: "Kuyimfuneko ukuba ningatyi ngenxa iluncedo." Kuba iingxelo trite na inzululwazi yonke, ukunika impendulo aluphelelanga kwi imibuzo malunga nempilo kunye nesondlo, ezisekelwe phezu umchiza ukwakhiwa lunezinto ziqukiwe iimveliso zokutya. Eziphilayo ufunda indima imichiza kwi ukutya kwaye lisebenza njengesiseko amalungu ubudala, isondlo kunye nococeko kokutya. Umsebenzi wayo: iindlela zokufunda elawula nokwenziwa kunye dissimilation ngayo kwaye acacise indima imichiza, ezifana sodium, potassium, magnesium neklorin ubomi iiseli zabantu yonke eziphilayo. Dietetics, kusekelwe kwizifundo kwemichiza, simisela ukuba izinga ngemihla ka-potassium, intsimbi, isalfure kunye nezinye izinto eziyimfuneko ukuze kugcinwe kwinqanaba oluqhelekileyo metabolic.

I phawu imichiza Ukubunjwa eziphilayo

Izazinzulu, biochemists lubonise ukuba izityalo, izilwanyana kunye nabantu ziqulathe yinxalenye iiseli ezininzi elements eekhemikhali lwezakhi. Potassium nezinki, xabiso lazo elo ke sicinga ukuba i macro, okt isiqulatho zabo iiseli mkhulu. Makhe sihlolisise umsebenzi wabo ngokweenkcukacha kwaye ufumanise ukuba ziya kuba yintoni kulingana nereyithi emihla potassium abantu.

indima potassium ukuthutha izinto ngokusebenzisa ingaphandle cell

Ukuze ubone indima potassium ukutshintshwa ion ngokusebenzisa bilayer yeseli inwebu usebenzise sisalathisi ezifana lomlingani permeability R. Oku kuxhomekeke Ebubanzini yeseli inwebu, ukunyibilika ion potassium kule nwebu lipid kunye ngumlingani kwe- D. Umzekelo, pores ye erythrocyte inwebu yabantu uyakhetha ngenxa ion potassium, kwaye lomlingani yabo permeability yi-4 emva kwemini / s. Kwakhona kakhulu low permeability inwebu yengalo elide neurocyte - Umzobo wesi - baxhomekeke ngokupheleleyo channels potassium. Nangona kufanele kuqatshelwe ukuba kudlula kunye nezinye ion, kodwa amaxabiso asezantsi permeability ukungavumelani kunelika-potassium. Ngokusekelwe kule nkcazelo ingasentla, oko kucaca yintoni indima kwinkqubo luvo inendima potassium, into yemini leyo umlinganiselo grams-2, kunye nabantu babandakanyeka kwiintlobo umsebenzi onzima - ukususela 2.5 ukuya 5 g

Isiphumo ion potassium kwinkqubo yegazi

Lonke ulwazi kunye nophando olunxulumene ekusebenzeni ngendlela eyiyo umsebenzi sentliziyo inkqubo yokujikeleza, okwangoku efanelekileyo kakhulu kungenxa yokwanda kwinqanaba iimeko uxinezeleko, ukunyusa isantya yobomi, ukwanda imikhwa emibi (ukutshaya, ukusela utywala phakathi kwabantu). Iziganeko angina, kwemithambo, ubungozi isifo sentliziyo ukufa icala ngoku phezulu kakhulu. Potassium, into yemini leyo eza emzimbeni wethu ngakumbi iimveliso ezixabisekileyo isilwanyana: intlanzi, yemvu, ubisi, normalizes uxinzelelo lwegazi, ulawula innervation le myocardium. Oku kunegalelo ekuthinteleni arrhythmias intliziyo: Arrhythmia kunye tachycardia. Akukho mfuneko yokuba ngoyaba into yokuba element macro ezifumaneka izityalo ezininzi, bakhonza ukutya kuthi, ezizezi: iitapile - 420 mg kwi beet - 155 mg kwi khaphetshu - 148 mg (100 g).

Good neqabane potassium - wemagniziyam

Kufuneka kuqatshelwe ukuba kunye potassium yokucolwa eqhelekileyo kwisisele ikwafuna ion wemagniziyam. Bayibiza macroelements kwaye kaninzi oku bekwenza ihambelana kakhulu ngayo nemvelo. Magnesium, potassium kunye ezifana, umlinganiselo yonke imihla apho eliphezulu (0.8 ukuya 1.2 g), ulawula ufe zihlunu skeletal, umsebenzi intliziyo, ulawulo ethwele amaza e izihlunu luvo, yaye ngoko macroelements ezisetyenziselwa nokuthintela ukuphuthelwa bobabini, ukuba nochuku, ukuphakuzela ithi ngenxa potassium kunye wemagniziyam ukuswela.

Zombini element macro uza kwizidlo kunye iimveliso ezifana irayisi, buckwheat, iimbotyi, isibindi kunye neenkukhu, kwakunye iziselo ubisi inegwele. ukusetyenziswa rhoqo ukutya okunjalo ihlawula ukungabikho potassium emzimbeni womntu.

Age kunye sex umahluko umthamo macronutrients

Njengokuba besesitshilo ngaphambili, zombini umkhondo element - nezinki, kunye potassium (yangosuku apho yahluka ukusuka grams-2 ukuya ku-4 ngosuku) - kuchaphazela ukuyilwa esiqwini ithambo kunye negalelo ekukhuleni kwayo kunye nokulungiswa. Oku kubaluleke kakhulu, ingakumbi ebuntwaneni. Ukuze ufumane anenani elifunekayo potassium (ukusuka 0,15 ukuya 0.3 g ngosuku) kwi ezityiwa umntwana kufuneka iziqhamo akhoyo kunye namaqunube, ingakumbi iiapilkosi, iibhanana, amaqunube. Ngokwaneleyo umntwana adle iyogurt, iyogurt, iinkukhu kunye namaqanda. Njengoko umzimba womntwana lukhula ngokukhawuleza, kufuneka nsuku entle imali eseleyo cell potassium. I-ion ze-imichiza inxaxheba ngakwicala leeprothini yokuqaphela, lo glycogen kwenziwa iipropati kumthamo igazi, kodwa kwakhona ukunika amaza luvo kunye imisipha. Kukho zonke izizathu ukuthi yonke le misebenzi yenziwa yi potassium. Izinga ngemihla babantwana yalo 460 mg. Needs lwesi sakhi, kwaye nokomeleza impilo umzimba ababhinqileyo. Daily kufuneka beze ukuya grams ezintathu potassium. Ngenxa yokuba iifom kakhulu lomsebenzi emzimbeni kwenziwa kakhulu ngabantu, ngokuba ngemihla izinga labo potassium kufuneka ibe ukuya ku-5 grams.

Zokudla zilumkisa ngelithi ukusetyenziswa iswekile ethe shinyi, ikofu, iibhloko utywala ukufunxeka potassium ukusuka ukudla kwisiqwenga zesisu. intsilelo Macroelements zingaphunyezwa ngokusebenzisa izakhiwo vitamin-ezimbiwa, ezifana "Duovit", "Supradin", okanye engena yomxhesho abantu imikhwa emibi, iziqhamo ezomisiweyo, walnuts, imbewu ithanga. Ngoko kuya kuba ngekhomyutha potassium ngemihla. Xa imixholo yawo womisa Iapilkosi - 2.034 g ezisekelwe 100 g imveliso. Lo mqulu kufuneka yahlulwe izidlo eziliqela kunokuba badle ngexesha, kungenjalo ukuze nigcine iimpawu ukuqunjelwa. Ngokunxulumene ukukhuthazwa izazinzulu yokuphila asebenzayo aye avelisa yokudla apho intsalela inkqubo- wemagniziyam eswele, potassium emzimbeni. Oku, ngaphezu kwabo bonke, intshayelelo kungena ezityiwa protein lula ukutya imifuno kunye nemixube zayo, akafuni kufuna unyango ubushushu elide kunye nokulungiselela iyabiliswa. Bona ziqulathe izinga potassium imihla grams - ukususela nge-3 4.7, kunye nemali efunekayo magnesium, calcium, intsimbi siphande izinto.

Kutheni kufuneka ibe ngokupheleleyo ukutya

Yintoni enokwenzeka ukuba umzimba wethu uza kufumana yokungabikho okanye ezingaphezu izinto ezifana magnesium potassium? kwiingxowa imihla ngemihla kubo, uwabize kufuneka 1,8-2 3-4,7 g kunye g, ngokulandelelana kwazo. nokuphazamiseka lwenkqubo yemfundo wokudla, ukuphazamiseka luvo, hypertension kunokwenzeka ngenxa ukuswela njengento ezifana potassium. norm Daily Kwakhona kufuneka ingadluli 4.7 grams, kungenjalo umntu ene polyuria, ukuphazamiseka zentliziyo kunye nezintso.
