The recommendation to eat rocks daily is a satirical and false claim originating from a joke article by The Onion, which some AI sources mistakenly picked up and spread as fact. Scientifically and medically, humans should not eat rocks at all. Eating rocks can damage teeth, tear the digestive system, cause serious health problems, and even be fatal. The correct number of rocks to eat per day for health is zero. Rocks are not a safe or viable source of nutrients for humans, and ingesting them is strongly discouraged by health professionals.
