I-calcium kanye ne-vitamin D iye yanconywa iminyaka njengendlela yokwelashwa okuphumelelayo ekuthuthukiseni impilo yethambo. Ucwaningo oluqhubekayo luye lwabonisa ukuthi i-calcium inciphisa ubungozi bokuqeda i-osteoporosis nokuphuka ikakhulukazi kubantu abadala kanye nabantu abadala. Ucwaningo oluthile lwamuva luye lwavusa ingxabano ebonisa ukuthi lokhu kungase kungabi njalo futhi kungenzeka ukuthi ukuphulwa kuyafana kungakhathaliseki ukuthi kune-calcium supplementation.
Ucwaningo lwe-calcium olwanyatheliswa kuyi- British Journal of Medicine lwabangela ukuthi izindaba ezikhishwayo zikhishwe ngokuphazamisa ukuphumelela kwe-calcium supplementation ukunciphisa ukuphuka kwamathambo. Iningi lethu lilalele futhi lifunde izindaba nsuku zonke ezikholelwa kulezi zihloko. Inkinga izindaba zivame ukwenzeka ngaphambi kokuba kukhishwe ubufakazi obuqinile. Izifundo zokuqala zisho ukuthi ucwaningo olwengeziwe luyadingeka futhi ucwaningo lwezilwane alukwazi ngempela ukusebenzisa emzimbeni wesintu. Izindaba eziningi zezindaba zivela kulolu hlobo locwaningo.
Izihloko ziyi-value yokushaqeka ngakho ngaphambi kokuxosha amabhodlela we-calcium nokuthululela ubisi phansi, ukuhlunga ubufakazi kuyadingeka ngempela. Sivela eminyakeni yobudala "ubisi lwenza umzimba omuhle" futhi kunciphise izifo ze-osteoporosis nge-supplements calcium enqunyiwe. Kungenzeka kanjani ukuthi imibiko embalwa yabezindaba isekelwe ekucwaningeni okuncane okubangele ukungabaza? Lokhu kuyindlela engcono kakhulu yokuthola abafundi kunokunikeza ukwaziswa okuningiliziwe okunembile mayelana nokucwaninga kwe-calcium ezindabeni zezindaba.
Yini eyayishiywe kulezi zihloko ukuthi abantu abangezela noma abafuna ukufaka nge-calcium kufanele bazi?
Okufanele Ukwazi
I- British Journal of Medicine yashicilela ucwaningo ngokuthi ngabe ukwandisa i-calcium emithonjeni yokudla noma ukuxhaswa kungaba usizo ekunciphiseni ama-fractures. Uke wakuthola lokho? Lezi zifundo azibhekiseli kumagugu ajwayelekile nsuku zonke e-calcium noma ethi i-calcium ayizuzisi. Bahlola uma kune-calcium eyengeziwe edingekayo ngaphandle kokudla okunomsoco okujwayelekile . Le mpikiswano ibilokhu iqhubeka iminyaka futhi ihlala ingavumelani.
Ubufakazi obengeziwe bokusekela i-calcium eningi njengoba kudingeka ekuthuthukiseni amathambo noma ukunciphisa ingozi yokuhlukumeza kuyadingeka. Ukubuyekezwa kocwaningo kuyamangalisa kodwa ukungahambisani phakathi kwezifundo kuqhubeka nokuba khona. Kubonakala sengathi abacwaningi abakwazi ukubona nokuqhathanisa ngokunembile ukutholakala kwengozi yokuphuza i-calcium nokuphuza.
Ezinye zezici zemihlangano ye-calcium zihlanganisa:
- Izilingo ezilawulwa ngokungahleliwe
- Izifundo zokuqapha
- Ukuhlolwa kwamaphuzu amane okuphuka - i-hip, i-vertebral, ne-forearm
Ezinye zobuthakathaka bokucwaninga kwe-calcium zihlanganisa:
- Ucwaningo oluthile lwezibalo
- Ukungenzi ukuhlolwa kwekhwalithi yezifundo kodwa besebenzisa imiphumela noma kunjalo
- Isikhathi esifushane sesilingo
- Ukusebenzisa i-bone mineral mass (BMD) njenge-endpoint esikhundleni sokuphulwa
- Ukunciphisa abahlanganyeli besilingo emiphakathini enempilo noma labo abaneengozi ephansi yokuqeda i-osteoporosis
Imiphumela yokucwaninga ibhekwa njengokungagculiseki ngokususelwa ekungeneni ububanzi bomphakathi kanye nokuphela kwesikhathi esiphezulu. Ezinye zezinto ezifunyenwe ziveze ubufakazi obuncane bokusekela i-calcium yokudla ekhulayo njengesici sokunciphisa ingozi yokuhlukumeza, noma kunjalo, ukwengezwa kwabonisa ukuthuthukiswa okungavumelani. Ucwaningo lwabonisa ukuthi inzuzo ye-calcium neyingozi ekudleni ngemithombo yokudla nokunye .
Olunye ulwazi olubalulekile
Ama-headlines athambekele ekuthembekeni kakhulu ekubhekaneni nokuhlukumezeka kunokuba abelane ngolwazi oluhle njengoba kwenzeke esimweni sokungabaza ukusebenza kwe-calcium. Ngokusho kokuthola ucwaningo, izithako ze-calcium zingase zibe nenzuzo emiphakathini uma isetshenziswe kabanzi, ibekezelela futhi ithathwa njengokuphephile. Lolu lwazi alufakiwe ku-athikili yezindaba.
Kubonakala sengathi kungenzeka ukuthi izinkinga zamathumbu ziyakhathazeka futhi zingase zibe nezinkinga zenhliziyo nangokwenyuka kwe-calcium-yakhuthaza isincomo esingajwayelekile sokungeze nge-calcium. Ngokusobala, ingozi engalungile idlula izinzuzo ezincane ngokusho kwezifundo ezimbalwa.
Iziphetho ezengeziwe ziveza ukuthuthukiswa okuncane ematheni amaminerali (BMD). Njengoba umkhawulo ulinganise ukuthuthukiswa kokungu-1-2%, isifundo sasihlolisisile ukuthi lezi zithole azibalulekile ukuze zisekele ingozi encane yokuphulwa. Umbuzo ozocatshangelwa lapha yikuphi ukuthuthukiswa okuncane okwenzekile kungabi nhlobo?
Ezinye izifundo zikhiqize ingozi e-15% ephawulekayo yokunciphisa ingozi yokuhlukana okuphelele ngokufaka i-calcium kanye ne-vithamini D. Ngaphezu kwalokho, ukutholakala okuningi kocwaningo kusekela i-calcium kanye ne-vitamin D ukwesekwa njengendlela yokungenelela okuphumelelayo ekunciphiseni ingozi yokuhlukumeza phakathi kwabantu abadala kuya kubantu abadala.
Izwi elivela
I-calcium kanye ne-vitamin D iboniswa ukuthi iyindlela yokwelapha ephumelelayo ukunciphisa ingozi ye-osteoporosis nokuqhekeka okulandelayo. Uma ucwaningo oluqinile emithonjeni ebalulekile efana ne-calcium ebuzwa, kubalulekile ukufunda ngaphandle kwezindaba zezindaba bese usebenza namaqiniso wangempela. Ucwaningo luyingxenye ebalulekile yokuhlinzeka ubufakazi bokusekela indima yamavithamini namaminerali empilweni yethu kanye nempilo yethu. Ucwaningo lwesintu oluvela emithonjeni enokwethenjelwa kuyindlela enhle kakhulu yokubuyekeza ulwazi oluthembekile. Uma ucabangela ukuthatha i-calcium, kunconywa ukuba uxoxe nodokotela wakho ngaphambi kokuthatha lokhu noma enye enye isengezo.
