Iyiphi indima kavithamini K emzimbeni?
Kukhona iphrotheni ebalulekile esicutshini semithambo evimbela i-calcium ukuthi ingakheki ezindongeni zemithambo yegazi, futhi idinga uvithamini K ukuze isebenze. Ngaphandle kwale vithamini, amaprotheni awasebenzi kangako, angandisa amathuba okuba sengozini ukwakheka kwe-calcium ezindongeni ze-arterial.
Lapho lokho kwakheka kwenzeka emithanjeni ye-coronary, kuhlotshaniswa ne-atherosclerosis nesifo senhliziyo. Ukunqwabelana kwe-calcium kweminye imithambo emzimbeni wonke nakho kuhlotshaniswa nokufa ngaphambi kwesikhathi.
Nakuba kungafakwanga kulolu cwaningo, uvithamini K ubuye wahlotshaniswa ne-a impilo engcono yamathambo, esinye isizathu sokuthi kungani abasubathi kufanele bacabangele ukwengeza ukudla okucebile kwe-K ekudleni kwabo. Olunye ucwaningo olushicilelwe ku-Nutrition lubike ukuthi i-vitamin K, okuyinto kuthuthukisa ibhalansi ye-calcium kanye namaminerali amathambo kuwo wonke umuntu, kunganciphisa amazinga okuphuka futhi kwandise ukuminyana kwamaminerali amathambo kubantu asebekhulile abane-osteoporosis. Nakuba ezinye izifundo zisebenzisa imithamo ephezulu ukuze zithole le miphumela, abacwaningi bangeze ngokuthi lokhu akunjalo ngaso sonke isikhathi, futhi ngisho nemithamo ephansi ingazuzisa impilo yamathambo, ikakhulukazi uma isetshenziswa. kuhlanganiswe ne-vitamin D.
