Safe Minerals to Consume

Here are a few examples of minerals found in rocks that are safe to eat and beneficial for human health when consumed in moderation:

Salt (Halite)

Common table salt, scientifically known as halite, is a mineral essential for human health. It acts as a flavor enhancer and is used in various food products. Essential for maintaining proper nerve and muscle function, salt is a crucial component of many diets, even though it should be consumed in moderation.

While not typically consumed directly, gypsum is found in some food products and can be included in dietary supplements. It is also a component of many antacids, aiding in digestion and offering relief from digestive discomfort.

Calcium Carbonate

This mineral is widely used as a dietary supplement for calcium, which is vital for bone health. It is also found in antacids, providing relief from heartburn and acid reflux. Commonly sourced from limestone, this mineral serves multiple purposes in the human body, making it a valuable supplement for many.

Clay (e.g., Bentonite)

In certain cultures, edible clay such as bentonite is consumed for its supposed health benefits, such as detoxification and improved gut health. However, it should be consumed cautiously, as too much can cause health issues.
