Geophagy, the deliberate act of eating soil, has been observed in various primate species, although the reasons for this behavior are poorly understood. The present study supports the general hypothesis that the physical and/or chemical nature of the soil is a likely reason for geophagy in hybrid macaque monkeys of Kowloon, Hong Kong. Samples were taken from areas where macaques were seen to be eating soil and from areas where there was no evidence of geophagy. Samples that were refused by the…

Mineralogical and Chemical Interactions of Soils Eaten by Chimpanzees of the Mahale Mountains and Gombe Stream National Parks, Tanzania
Comparison with control soils from the same areas showed lower levels of carbon and nitrogen in the eaten soils, a relationship confirmed by surface analysis, and a new adaptive advantage of geophagy is proposed, based on the prevention of iron uptake.
The Chemistry and Mineralogy of Three Savanna Lick Soils
Three lick soils were sampled from the Mkomazi Game Reserve, Tanzania, and subjected to geochemical and mineralogical analysis. Compared to 88 samples of topsoil collected for a reconnaissance
Geophagy by the bonnet macaques (Macaca radiata) of southern India: A preliminary analysis
Bonnet macaques (Macaca radiata) in the Marakkanam Reserved Forest of southern India consume termitaria soils that would act as a pharmaceutical agent to alleviate gastrointestinal upsets and control diarrhoea.
Soils Consumed by Chimpanzees of the Kanyawara Community in the Kibale Forest, Uganda
We previously reported on a study of 4 soils that chimpanzees of the Kanyawara community in the Kibale National Park, Uganda consumed on a near-daily basis. We suggested that iron was a possible
Pedological Analysis of Geophagic Behaviour in Captive Borneo Orangutan (Pongo pygmaeus)
Geophagy (soil-eating) is one of the well-known behaviours in many primate species, but the factors influencing this behaviour have been less known. In the captive environment of Tama Zoological

It is suggested that total chemical analyses of these materials are of little relevance unless supported by a physiologically based extraction test, this approach being essential in any study seeking to confirm the nutrient supplementation hypothesis.
Possible mineral contributions to the diet and health of wild chimpanzees in three East African forests
Tmite mound soil is shown to be a rich source of minerals, containing high concentrations of iron and aluminum, which are the highest yet found in any of the mineral sources consumed by East African chimpanzees.
Geophagy in chacma baboons: patterns of soil consumption by age class, sex, and reproductive state
The data indicate that pregnant chacma baboons spent more time consuming soil at monitored geophagy sites than baboons of any other age class, sex, or reproductive state, and the soils consumed would be effective at alleviating gastrointestinal distress and possibly supplementing minerals for all age/sex classes, but potentially for different age/ sex requirements.
Geophagy of Yunnan snub-nosed monkeys (Rhinopithecus bieti) at Xiangguqing in the Baimaxueshan Nature Reserve, China
The data indicate that geophagy in R. bieti is best explained as a response to nutrient deficiency, as soil consumed by the monkeys was significantly higher in calcium, copper, zinc, iron, manganese, and sodium than that consumed by control samples.
Adaptive function of soil consumption: an in vitro study modeling the human stomach and small intestine
It is concluded that gastrointestinal adsorption is the most plausible function of human geophagy, and adaptive advantages include greater exploitation of marginal plant foods and reduced energetic costs of diarrhoea, factors that could account for the high frequency ofGeophagy in children and pregnant women across the tropics.


Geochemistry and clay mineralogy of soils eaten by Japanese macaques
Preliminary data suggest there is no chemical stimulus in soil eating behaviour in Japanese macaques and the mineralogy of the clay fraction could find only a possible stimulus from ingesting plagioclase and orthoclase minerals.
Soil-eating by red leaf monkeys (Presbytis rubicunda) in Sabah, Northern Borneo
Observations on the diet of a group of red leaf monkeys from Sabah, northern Borneo are summarised and the composition of termite mounds is compared with that of surrounding top-soil in an effort to determine possible reasons why termite-mound soils are selected.
Geochemistry and clay mineralogy of termite mound soil and the role of geophagy in chimpanzees of the Mahale Mountains, Tanzania
These analyses and preliminary observations linking geophagy with instances of severe diarrhea, and other signs of gastrointestinal upset in the Mahale chimpanzees, suggest that one function for the ingestion of this substance by chimpanzees may be to help provide temporary relief from gastrointestinal ailments.
Water-plant and soil consumption by guereza monkeys (Colobus guereza) : a relationship with minerals and toxins in the diet?
A comparison of estimated mineral intakes and requirements suggests that the dry-land diet of the guereza population may be deficient in sodium, and perhaps barely sufficient in copper, manganese, and zinc.
Detoxification and mineral supplementation as functions of geophagy.
It is concluded that adsorption of tannic acid in traditional acorn preparation methods in California and Sardinia helped make these nuts palatable and suggested that the physiological significance of geophagy made it important in the evolution of human dietary behavior.
Ingested soil: bioavailability of sorbed lead, cadmium, cesium, iodine, and mercury
Ingestion of soil, inadvertent or otherwise, is an important route of exposure for contaminants that are not geochemically or biologically mobile. There is little known about the bioavailability of

In vitro analyses showed that the glycoalkaloid, tomatine, was effectively adsorbed by four classes of edible clays over a range of simulated gastrointestinal conditions, suggesting geophagy as a solution to the impasse chemical deterrents pose to the process of domestication and to chemical constraints on plant exploitation by non-fireusing hominids.
Geophagy in moustached tamarins,Saguinus mystax (platyrrhini: Callitrichidae), at the Río Blanco, Peruvian Amazonia
Geochemical analyses of the soils that were consumed showed elevated concentrations of several elements in the ant mound sample compared to the other two soil samples, suggesting that soil feeding in moustached tamarins serves in mineral supplementation.
Ant eating behavior of mountain gorillas
Eleven cases of feeding on driver ants by mountain gorillas (Gorilla gorilla beringei) are described, and ant eating appears to be a socially acquired and transmitted taste.
