“…Despite the progress made in the development of in vitro bioaccessibility (IVBA) tests that mimic the conditions of the human GI environment, and determination of the bioaccessibility of ingested soil chemical elements, some methodological constraints still remain [see e.g., ( 23 , 118 , 119 )]. Refinements in the methodology of systematic in vivo studies are therefore recommended on geophagic soils ( 120 ).…”

This article synthesises current knowledge and identifies research gaps on the still intriguing aspects of the subject of geophagy as practised in Africa. Despite the voluminous research literature that exists on the subject, geophagy in Africa is still a largely misunderstood phenomenon. Although the practice is not confined to any particular age group, race, gender, or geographical region, in Africa it is most commonly recorded among pregnant women and children. Till now, the precise aetiology of geophagy remains obscure; but the practice is thought to have both beneficial effects such as having a role as a nutrient supplement, as well as several demerits. An updated critical review of human geophagy in Africa - with a section on (other) animal geophagy -, highlights several aspects of the practice that need further research. A comprehensive bibliography is assembled, comprising some of the more pertinent and recently published papers (mostly post-dating the year 2005), as well as older seminal works, providing a baseline and robust framework for aiding the search process of Medical Geology researchers and those from allied fields wanting to explore the still poorly understood aspects of geophagy in Africa.

“…There are not many studies on the characteristics of geophagic clay [9][10][11][12][13][14][15][16][17]. Geophagia is universally recognized as a deliberate habit of consuming earthy materials including clays, soils, and sediments [11].…”
