Calcium deposits are caused by way too little saturated fat in your diet, and way too much carbs in your diet. You need saturated fat in abundance in your diet, in order to form viable cells in your body. Every cell in your body, including bone cells, is encased in a lipid layer of saturated fat. With trillions of body cells, all being built, and replaced constantly, you need a lot of saturated fat in your diet, to keep a proper cell building process working. Carbs, sugars and starches, leach calcium away from weak cell structures, in the absence of enough saturated fat in the diet to make proper cells. When your bone cells aren't properly constructed, by having thin cell walls, because you don't get enough saturated fat (from animal sources) in your diet, calcium will be pulled from your bones and teeth, into your blood stream. Your body still tries to hold on to the calcium in your blood stream, by putting it in other places, such as muscles and joint cartilage. In cases of temporary famine conditions, that can be reversed by you starting to eating well again, as in getting more saturated fat into your diet, when the famine is over. Constant low fat, high carb diet, can result in permanent injury to many body parts.
