La umfutho wegazi ophakeme kungathinta phakathi kuka-10 no-15% wabantu. Lesi sibalo sinokuthambekela kokwanda, ngoba sisuke kubantu abayizigidi ezingama-8,6 saya kwabangu-10,5 abelashwa phakathi kuka-2000 no-2006, okudala inkinga yezempilo yomphakathi.
Amazambane kungenye yokudla okusetshenziswe kakhulu eYurophu, ifinyelela inani lamakhilo ayi-15 umuntu ngamunye ngonyaka. Kuyathakazelisa ukuthi eFrance, ukusetshenziswa kuye kwanda kancane eminyakeni edlule, ngenxa yezindleko zayo eziphansi. Kodwa futhi kwenzeka e-United States, lapho amazambane athathwa njengemifino, ngokuzenzisa kokuqukethwe kwayo okuthakazelisayo ku-vitamin C, i-potassium, eyaziwa ukunciphisa umfutho wegazi.
Ngakho-ke, kungumphumela oguqukayo osanda kubonwa kulolu cwaningo ofake abantu baseMelika abangaphezu kwe-185.000. Ngaphandle komphumela obhalwe kahle we-potassium egazinil, amazambane awenziwe nje nge-potassium, kodwa futhi nesitashi esigaywa kahle kakhulu. Lesi yisifundo sokuqala ukukhombisa umphumela wesikhathi eside wokusetshenziswa kwamazambane njalo.
Abaphenyi basebenzise idatha kusuka ezifundweni ezintathu ezinkulu zaseMelika eminyakeni engaphezu kwengu-20, ebhalise abesilisa nabesifazane abangu-186.453. Bacubungule izinto eziningi njengobungako bomzimba womuntu, ubulili babo, isimo sabo ngokuya ngogwayi, ukusebenza kwabo ngokomzimba, konke ukudla abakudlayo, amagalelo abo kumavithamini namaminerali, njalonjalo. Kepha lezi zinguquko ziyithinte kancane kakhulu imiphumela.
Iziphetho zimi ngale ndlela elandelayo: ukudla amazambane ama-4 noma ngaphezulu ngesonto kuhlotshaniswa nakho ingozi yomfutho wegazi ophezulu lenyuke ngo-17%. Umphumela ocacile ekucindezelweni kwegazi ubonwe ngamazambane amazambane. Kulolu cwaningo, ukufaka ingxenye yamazambane ngengxenye yemifino kuhlotshaniswa nakho ukuncipha okukhulu kwengcindezi yegazi. Kodwa-ke, ukusetshenziswa kwamazambane amazambane bekungahlotshaniswa nokwanda, kepha kunokwehliswa komfutho wegazi.
