The recommendation to eat rocks daily is actually a piece of satire and misinformation. Some satirical sources, like The Onion, have humorously suggested eating at least one small rock a day for health, but this is not a valid or safe health recommendation. Geologists or health professionals do not advocate eating rocks. Eating hard, non-food items like rocks can pose serious risks, including choking, dental damage, and potential ingestion of harmful substances like toxins or heavy metals. There is no genuine scientific endorsement for eating rocks as a part of a healthy diet. In summary, no rocks should be eaten per day for health. Instead, focusing on a balanced diet with proper minerals and nutrients from food sources is recommended.
