can you eat chalk

Eating chalk is generally not safe or recommended. While small amounts of chalk are usually non-toxic, consuming chalk can cause digestive problems like stomach aches, constipation, and intestinal blockages, especially in children. Chalk does not provide any nutritional value and may interfere with nutrient absorption, leading to deficiencies. It can also damage tooth enamel and may contain harmful impurities such as lead, posing serious health risks. Regular or large amounts of chalk consumption can lead to more severe issues including kidney stones, nutritional imbalances, and toxicity. Eating chalk is often linked to a condition called pica, which is associated with underlying nutritional or psychological issues and requires medical evaluation and treatment.
