The best food to feed growing bones and joints in bone stock. Ie, simmer beef, chicken, pork etc bones all day long to make a soup stock. This stock is then rich in calcium, magnesium and other minerals and nutrients that your body needs. When it comes to milk maybe you are drinking too much. You need to balance your intake of calcium vs magnesium. Leafy green vegetables are a good source of magnesium and calcium too. The processed milk we buy is stores these days is overrated as a source of calcium.
