African iron overload, also known as Bantu siderosis or dietary iron overload, is an iron overload disorder first observed among people of African descent in Southern Africa and Central Africa. Dietary iron overload is the consumption of large amount of home-brewed beer with high amount of iron content in it. Preparing beer in iron pots or drums results in high iron content. The iron content in home-brewed beer is around 46–82 mg/L, compared to 0.5 mg/L in commercial beer. Dietary overload was prevalent in both the rural and urban Black African population, with the introduction of commercial beer in urban areas, the condition has decreased. However, the condition is still common in rural areas. Until recently, studies have shown that genetics might play a role in this disorder. Combination of excess iron and functional changes in ferroportin seems to be the probable cause. This disorder can be treated with phlebotomy therapy or iron chelation therapy.
