Izindaba ezimnandi kubantu abanesifo sezinso zimenyezelwe ososayensi baseJalimane. Ngokusekelwe ocwaningweni olwenziwe, ochwepheshe baye bathola ukuthi ukusetshenziswa kwe-cocoa kuvikela iziguli kulesi sigaba ekuhlulekeni kwenhliziyo. Ngokusho kodokotela, abantu abaphethwe yizinso bavame ukushona ngenxa yokwehluleka kwenhliziyo okuhambisana nalesi sifo.
Ukuze balondoloze impilo yabo, kufanele baye ngokuhlelekile ku-dialysis ukuze bagcwalise umzimba ngezakhi ezibalulekile - i-catechin ne-epicatechin. Kodwa lezi zingxenye ezimbili ezibaluleke kakhulu zikhona ekwakhiweni kwe-cocoa ejwayelekile. Uma ufaka i-cocoa ekudleni kwakho, ungafinyelela impilo engcono, odokotela bathi. Ososayensi bakuqinisekisile ubuqiniso balawa magama ngesikhathi socwaningo. Basizwe ngabahlanganyeli abangu-26 abanesifo sezinso. Bahlukaniswa ngamaqembu amabili. Abantu kwelinye baye bafaka ngempumelelo ukudla nge-cocoa inyanga yonke. Amalungu amanye amazinga omsoco agcinwe nge-placebo.
Nanku umphumela: abaphenduli ababeseqenjini lokuqala lokulawula babenomfutho wegazi ophansi futhi bazinzile ukugeleza kwegazi. Ezinye izinguquko ezifanayo azizange ziqashelwe. Kuyathakazelisa ukuthi ushokoledi, ogcwele i-cocoa, awunawo umphumela ofanayo emsebenzini wenhliziyo, ngoba awunawo ama-catechin nama-epicatechin.
