Zvinonhuwira mundiro zvinobatsira kurarama kwenguva refu. Kudya chikafu chinonhuwira kwakabatana nenjodzi yakaderedzwa yekufa kwekutanga, masayendisiti akagumisa. Maererano nenyanzvi, nyaya iyi inoda imwe ongororo.
Chidzidzo ichi chakabvunza vanhu vangangosvika zviuru zvishanu muChina kuti vanodya kangani chikafu chinonhuwirira. Vatori vechikamu vaive pakati pe500000 ne30 yemakore pakatanga chidzidzo uye vakateverwa kwemakore 79. Munguva iyi, 7 vanhu vakafa.
Sezvazvakazoitika, vanhu vaidya chikafu chinopisa zuva rimwe kana maviri pasvondo vaive negumi muzana mukana wekufa panguva yekudzidza zvichienzaniswa nevamwe. Mhedzisiro iyi yakaburitswa muna Nyamavhuvhu 10 muThe BMJ magazini.
Pamusoro pazvo, vanhu vaidya zvinorungwa mazuva matatu pasvondo kana kupfuura vaive nechikamu che14% chekufa pane avo vaidya zvinorungwa zvisingasviki kamwe chete pasvondo.
Chokwadi, uku kwaingove kucherechedzwa, uye kwave kutanga kutaura kuti pane hukama hwechikonzero pakati pechikafu chinorunga uye kufa kwakaderera. Munyori wezvidzidzo Liu Qi, purofesa anoshanda paHarvard School of Public Health muBoston, anoti data rakawanda rinodiwa pakati pevamwe vanhu.

Semuenzaniso, zvikafu zvinonhuhwirira zvakaratidzwa kuderedza kuzvimba, kunatsiridza kuparara kwemafuta emuviri, uye kushandura kuumbwa kwemabhakitiriya emudumbu.
Vatori vechikamu vakabvunzwawo kuti ndezvipi zvinonhuhwira zvavanoda—mhiripiri, mhiripiri yakaomeswa, muto, kana mafuta. Pakati pevanhu vaidya zvokudya zvinonaka kamwechete pavhiki, vazhinji vaifarira mapepper matsva uye akaomeswa.
Parizvino, masayendisiti anotenda kuti inoda kusimbiswa kana zvinonhuwira zvine mukana wekuvandudza hutano uye kuderedza kufa, kana zvichingova chiratidzo chemamwe madyiro uye mararamiro.
