Most people have gall and liver stones mainly due to a diet high in insoluble fats and animal fats, indigestible proteins, refined sugars and refined carbohydrates combined with a lack of adequate insoluble dietary fiber. The liver and gall bladder would normally be able to break down these acid-forming foods but due to their over consumption the bile in the liver and gallbladder becomes super saturated and insoluble and "stones" are created as these fats and cholesterol solidify. These stones can also become hard as sometimes they are encased in calcium and other minerals.
