I-calcium: Izibonelelo kunye neengozi kuMzimba wethu

Imvelaphi yembali:

Ngomnyaka we-1808, i-calcium yaqala ukuhlukaniswa ngusokhemisti u-Humphrey Davy.

Isiqulatho se-calcium emzimbeni wendoda simalunga ne-1.5 kg, emfazini – i-1 kg kunye ne-99% yayo isemathanjeni amathambo.

Iihomoni ezintathu zilawula ukuxinwa kwe-calcium egazini:

Ihomoni yeParathyroid yincindi yamadlala eparathyroid eqokelela icalcium emathanjeni xa inqanaba layo egazini liyancipha.

I-Calcitonin - ihomoni ye-thyroid eqinisekisa ukugcinwa kwe-calcium kwizicubu zethambo xa inqanaba lokugqibela egazini liba phezulu kakhulu.

I-Vitamin D okanye i-1,25 - i-dihydroxycholecalciferol, eyenziwa esikhumbeni phantsi kweempembelelo zemitha ye-ultraviolet kwaye iza nokutya, iqinisekisa ukufunxwa kwe-calcium ekudleni okuvela emathunjini.

Impembelelo yeCalcium kumzimba:

I-calcium inceda ukucutheka kwemisipha. Kwimeko ye-calcium metabolism disorder, ukwehla kwethoni ye-muscle kubonwa, isisu siba sivila kwaye sikhululekile, kwaye umntwana uqala ukuhamba emva kwexesha.

Ngaphandle kwe-calcium, umsebenzi wombane kunye nokuphazamiseka kwentliziyo akunakwenzeka.
Le ion ingundoqo kwi-contraction yemisipha egudileyo yemithambo yegazi (ukugcinwa koxinzelelo), amathumbu (peristalsis), isibeleko, kunye nesinye. Izihlunu ezigudileyo zamalungu angaphakathi zihlupheka ngenxa yokungabikho kwetoni ye-calcium, ekhokelela ekubeni i-organ prolapse kunye nokuqunjelwa. Umsebenzi wesisu uba livila kwaye ucotha.

I-calcium ibonelela ngenkqubo yesenzo se-neurotransmitter ekuhanjisweni kolwazi phakathi kweeseli zengqondo, imithambo-luvo, kunye nezihlunu. Ukungabikho kweCalcium kuphazamisa iindlela zokuvuselela kunye nokuthintela kwinkqubo ye-nervous central. Ebantwaneni, oku kubonakaliswa kukoyika okanye ukulila ebusuku, ukuphakuzela, ukuphuthelwa, nokushukuma ngokugqithiseleyo. Kubantu abadala, kubonakala ngoxinzelelo, ukuxhalaba, ukungakwazi ukukhumbula, ukunciphisa ukunyamezela, kunye nokudinwa.
Ukunciphisa inani le ion egazini lihamba kunye nomphumo wokuxhamla kwiiseli ze-nerve kunye nemisipha. Ngenxa yoko, i-tetany iyenzeka - i-spasms ebalulekileyo yemisipha yamathambo, kuquka imilenze kunye ne-larynx.

I-calcium idlala indima ebalulekileyo kwinkqubo yokujika kwegazi. Ngokuncipha kwinqanaba le-calcium egazini, i-platelet adhesion kunye ne-blood clot compaction iphazamiseka, kwaye ixesha lokuphuma kwegazi lide.

Ukomelela kwamathambo emva kwamazinyo ngokuthe ngqo kuxhomekeke kwinani leetyuwa ze-calcium kuwo. Kwakhona, i-skeleton isebenza njenge-calcium reservoir, ukusuka apho inxalenye ethile ingena egazini njengoko kufuneka, okanye i-excess ifakwe.

Idosi yemihla ngemihla ye-calcium:

• I-500 okanye i-1000 mg ngosuku - kubantu abadala.
• Ukuya kuthi ga kwi-2000 milligrams ngosuku - kumfazi oncancisayo.
• I-1500 milligrams ngosuku - kumfazi okhulelweyo.

Iimpawu zokunqongophala kwe-calcium:

Iimpawu zokunqongophala kwe-calcium emzimbeni ziquka ezi mpawu zilandelayo ezibonakala zingahambelani:

Ukoyika, ukuba shushu, intliziyo ebetha ngamandla, ukuqaqanjelwa, ukuba ndindisholo kwemilenze nemilenze, ukukhula kancinane kwabantwana, uxinzelelo lwegazi oluphezulu, ukuqhekeka nezikhonkwane; intlungu edibeneyo, iyancipha "umda weentlungu", ukuya esikhathini esinzima.

Izizathu zokunqongophala kwe-calcium:

Ukunqongophala kwe-calcium kunokubangelwa kukutya okungenakulungelelaniswa (ingakumbi ukuzila ukutya), i-calcium ephantsi ekudleni, ukutshaya kunye nokusetyenziswa kwekhofi ngokugqithiseleyo, i-dysbiosis, i-vitamin D eyaneleyo, isifo sezintso, isifo se-thyroid, ukukhulelwa, ukuncelisa, kunye nokuyeka ukuya exesheni.

Ukuthatha i-calcium kakhulu kunokukhokelela kwi-hypercalcemia, enokubangela ezi ngxaki zilandelayo:

• Ukunyuka kwe-asidi yejusi yesisu, kunokukhokelela kwi-gastritis kunye nezilonda zesisu.
• I-calcification (i-deposition ye-calcium salts kwi-soft tissues okanye izitho, ezingafuneki ziqulethe iityuwa kwindawo engenakunyibilika).
• Izifo zentliziyo: i-angina pectoris, bradycardia.
• Igawuthi.
• Ukunyuka kwenkqubo yokujika kwegazi.
• Isifo samatye esintso, nephrocalcinosis.
• Ukunciphisa ithoni yemisipha egudileyo.
• Ukudakumba kwe-excitability ye-nerve fibers kunye nemisipha yamathambo.

Imithombo ye-calcium:

I-calcium ifumaneka ngobuninzi kwi-cottage cheese, ubisi, ukhilimu omuncu, i-cheeses enzima kunye ne-processed, kunye nezinye iimveliso zobisi. Kusuka kubo ukuba ixutywe ngokukhawuleza kwaye kulula, ngelixa ipesenti ye-fat content (umzekelo, i-kefir okanye i-yogurt) ayinandaba.

Eminye imithombo ye-calcium sipinatshi, iparsley, imifuno, iimbotyi, ikholifulawa, ibroccoli, ihorseradish, itswele, itshizi yesoya, ama-apile, amapere, iiapilkosi ezomisiweyo, intlanzi, amandongomane, imbewu kajongilanga, kunye neealmondi eziswiti.
