What are the pros and cons of eating chalk?

Eating chalk may provide some minerals like calcium, but it poses significant health risks. Consuming chalk can lead to digestive issues, blockages, and exposure to harmful substances if it contains additives or impurities. Additionally, craving non-food items like chalk may indicate a condition known as pica, which requires medical attention. Overall, while it might seem harmless, the potential health risks outweigh any perceived benefits.
