Can you eat chalk?
No, you should not eat chalk. Chalk is a non-food item, hence it is not edible. Although consuming small amounts of chalk may not be harmful to you but if consumed regularly and in larger amounts, it can result in major health problems, as well as can cause severe damage to the digestive system and internal organs.
What is chalk made of?
Chalk is made up of calcium carbonate (CaCO3), which is a kind of limestone formed from the shells of smaller aquatic animals, regarded as foraminifera, and from the calcareous remains of aquatic algae called coccoliths. In addition to calcium carbonate, chalk also has minor amounts of silt and clay.
Widespread sediments of chalk are found in various parts of the world. Chalk typically has white or light grey colour. It is very perforable, porous, and delicate hence, easily breakable.
Pastel chalks are made up of calcium sulfate (CaSO4), which is acquired from gypsum (CaSO4-2H2O). Gypsum is a mineral that is formed by the accumulation of ocean brine; it is also present in the limestone.

Causes of chalk addiction
Various factors are known to cause can chalk addiction, for instance::
Pica: Chalk craving is mostly associated with a condition known as Pica. Pica is an eating disorder where a person craves or eats non-food items that have no nutritional benefits such as, chalk, coal, soap, crayons, paper, soil, washing powder, and ice.
Mental disorder– Many times, pica is linked with other mental health conditions or disorders. It is believed that mental disorders drive the addiction of eating chalk in some people, all the time.
Nutrient deficiency– Chalk craving also relates to a diet that lacks vital nutrients. Lack of beneficial nutrients in the diet induces the body and the mind towards compulsive disorder. For instance, when people suffer from iron deficiency, their bodies lack enough iron to produce haemoglobin. This triggers unusual cravings including that of chalk.
Pregnancy– Often pregnant women are found to crave unusual items including chalk, pickles, ice, etc. It may be because women experience major physical and hormonal changes during pregnancy and their sense of taste and smell can be considerably affected.
Poverty- Poor people often become a victim of pica because they do not have proper food easily available to them, so they eat chalk to minimize their hunger.

- Pregnant women

Treatment of chalk addiction

If the person has a nutritional deficiency as revealed by a blood test, the doctor will recommend nutritional supplements to make up for the deficiency. In many cases, supplements that fulfil nutritional requirements are enough treatment to put an end to the craving and addiction.
However, if eating chalk is related to some other condition, such as autism or obsessive-compulsive disorder, prescription medication and appointments with a psychologist might be suggested.
