Abstract
Naked eye examination of coronary artery and aortic atherosclerosis was made on 523 unselected necropsies performed on South African Bantu subjects of ages from 20 to 70 + years, at Baragwanath Hospital, Johannesburg. Severe atherosclerotic lesions were found to be very much less common compared with corresponding American and Danish hospital populations. The habitually low fat intake and low serum cholesterol concentrations exhibited by these people are in harmony with the low incidence of severe atherosclerosis observed among them.
