Okuqukethwe
Ngokusho kochwepheshe abaningi, i-asidi ephezulu kakhulu yomzimba iphazamisa ukusebenza okuvamile kwezinhlelo zesitho, futhi azikwazi ukuzivikela ezinhlobonhlobo zamabhaktheriya namagciwane.
I-pH iyinani lama-athomu e-hydrogen esixazululweni esinikeziwe. Uma i-7, khona-ke iyindawo engathathi hlangothi, uma ivela ku-0 kuya ku-6,9, khona-ke iyindawo ene-acidic, kusukela ku-7,1 kuya ku-14 - i-alkaline. Njengoba wazi, umzimba womuntu isisombululo samanzi esingu-80%. Umzimba uzama njalo ukulinganisa isilinganiso se-asidi ne-alkali kulesi sixazululo.
Imiphumela yokwephulwa kwebhalansi ye-acid-base emzimbeni
Uma ibhalansi ye-acid-base iphazamiseka, khona-ke lokhu kungabangela ukuphazamiseka okukhulu emzimbeni. Uma udla ukudla okune-asidi eningi futhi kungenamanzi anele, ukugcwala kwe-asidi emzimbeni wonke kwenzeka. Lokhu kufaka phakathi amasoda, okusanhlamvu, ukudla okunoshukela, esikhundleni sikashukela, izinto ezibhakiwe, imikhiqizo yenyama, nenyama.
I-Acidification iyingozi ngoba yenza kube kubi kakhulu ukudluliswa komoyampilo kuwo wonke umzimba, ama-micro- kanye nama-macroelements aqala ukumuncwa kabi. Lokhu kungabangela, okokuqala, ukuphazamiseka ohlelweni lokugaya ukudla, i-cell metabolism, futhi kubangele izifo zenhliziyo, izifo zesikhumba, ukwehla kwamathambo, ukuzivikela komzimba, nokunye. Endaweni lapho ibhalansi ye-acid-base ikhombisa i-acidic, izimuncagazi ezahlukahlukene, kufaka phakathi amagciwane, isikhunta namagciwane, zikhula futhi zande ngokushesha.
Umzuzi kaNobel u-Otto Warburg uthole umklomelo wakhe ngokuthola ukuthi amangqamuzana omdlavuza awaphindaphindi endaweni egcwele umoya-mpilo, futhi kamuva kwafakazelwa ukuthi amagciwane, amagciwane kanye nesikhunta azisebenzi endaweni enjalo. Uma iphezulu i-pH, okuyi-alkaline, iyanda ukugcwala kwama-molecule omoya-mpilo (i-calorizer). Endaweni ene-acidic, ukugcwala kwe-CO2 kuyanda futhi kwakheka i-lactic acid, okudala izimo ezidingekayo zokukhula kwamaseli omdlavuza.
Ungahlola kanjani i-pH yomzimba?
Kulula kakhulu ukuhlola ibhalansi ye-acid-base yakho usebenzisa ukuhlolwa okukhethekile - iziqephu zokuhlola zephepha le-litmus, elingathengwa ekhemisi. Ibhalansi ye-pH engcono kakhulu yi-6,4-6,5. Kungcono ukunquma ibhalansi yakho ye-acid-base ihora elilodwa ngaphambi kokudla, noma amahora amabili ngemuva kwalokho.
I-pH yomchamo ingashintshashintsha usuku lonke. Uma inani layo liyi-6,0-6,4 ekuseni futhi 6,4-7,0 kusihlwa, asikho isizathu sokukhathazeka. Kodwa-ke, uma ukuhlolwa kukhombisa u-5,0 nangaphansi, khona-ke i-pH yomchamo iba ne-asidi ebukhali, futhi uma i-7,5 noma ngaphezulu, khona-ke ukusabela kwe-alkali kuyanqoba. Ngenani le-pH lomchamo, unganquma ukuthi amaminerali angena kanjani emzimbeni wethu, isibonelo, i-calcium, i-sodium, i-magnesium.
Ngokuqondene ne-pH yamathe, inani layo libonisa umsebenzi osebenzayo wama-enzyme ku-alimentary tract, ikakhulukazi isibindi nesisu. I-acidity evamile yamathe axubile ingu-6,8-7,4 pH. Ngokuvamile kukalwa emini esiswini esingenalutho noma amahora amabili ngemva kokudla. I-asidi ephansi yomlomo womlomo ngokuvamile iholela ekuboleni kwamazinyo, isifo sezinsini, nokuphefumula okubi.
Yiziphi izindawo ezine-asidi ne-alkali?
Emithi, kunegama elithi "acidosis" - lokhu kuyi-hyperacidity. Ukuphuza uphuzo oludakayo oluningi kanye nezinkinga zesifo sikashukela kuvame ukuholela kulesi simo. Ngokukhuphuka kwe-acidity, izinkinga zenhliziyo nemithambo yegazi zingabonwa. Umuntu angakwazi ukukhuluphala ngokushesha ngokwanele. Kaningi ezimweni ezinjalo kukhona izifo zezinso, esinyeni kanye nokuncipha kokuzivikela komzimba.
Ukwanda kwezinga le-alkali emzimbeni kubizwa ngokuthi i-alkalosis. Kulokhu, ukumuncwa kabi kwamaminerali nakho kuyabonwa. Isizathu salesi simo emzimbeni kungase kube ukusetshenziswa isikhathi eside kwemithi yokwelapha equkethe inani elikhulu le-alkali. I-Alkalosis ayivamile ngokwanele, kodwa futhi ingabangela izinguquko ezimbi nezimbi emzimbeni wethu. Lokhu kuhlanganisa izifo zesikhumba nesibindi, iphunga elimnandi nelizwakalayo elivela emlonyeni, nabanye.
Ungayigcina kanjani i-pH evamile?
Ukugcina ibhalansi ye-acid-base efanelekile yomzimba, udinga ukuphuza amanzi anele (30 ml nge-1 kg yomzimba). Ngokuqondene nokudla, kufanele kube nokudla okune-alkali okuphindwe izikhathi eziningana kunokudla okune-asidi.
Ukudla kwezitshalo, njengemifino nezithelo, kukhuthaza ukwakheka kokusabela kwe-alkali, okusanhlamvu, inyama, ukudla okugayiwe ngendlela yamasoseji, imikhiqizo eqediwe, imikhiqizo yokubhaka - i-acidic. Ukugcina ibhalansi ye-acid-base elungile, kuyadingeka ukuthi ukudla kubuswe ukudla kwezitshalo.
Odokotela bathi kuzuzisa thina kakhulu ukugcina izinga elifanele le-asidi ne-alkali emzimbeni. Kuphela ngebhalansi ye-pH efanelekile, umzimba wethu ubamba izakhi kahle.
Umzimba wethu unezinqubo zemvelo ezithuthukisa ibhalansi ye-acid-base. Lawa ama-buffer systems egazi, uhlelo lokuphefumula kanye ne-excretory system. Lapho lezi zinqubo ziphazamiseka, umzimba wethu ukhulula ama-acids emgudwini wamathumbu, izinso namaphaphu, kanye nesikhumba sethu. Iyakwazi futhi ukunciphisa ama-asidi ngamaminerali futhi iqongelela ama-acids ezicubu zemisipha (i-calorizator). Uma uzizwa ukhathele, kungase kusho ukuthi i-ayoni eku-hemoglobin egazini lakho yenza i-asidi ingabi namandla. Uma kubonwa isiyezi, ubuhlungu bekhanda, amajaqamba nokuqwasha, lokhu kungase kubonise ukuthi i-magnesium isetshenziswa ezinzwa, izicubu zemisipha namathambo.
Nazi ukuthi zingaki izinkinga zempilo ezingavela ngenxa yokungalingani kwe-acid-base. Ungavumeli izinto zihambe zodwa, cabangela ukuthi ukuvimbela kuyisihluthulelo sempilo enhle. Gada i-pH yomzimba wakho njalo ukuze ugweme izifo eziningi.
