 Calcium is not the only nutrient that’s important.  Vitamin D, magnesium, Boron, and zinc are  also important for healthy, strong bones.   For example, vitamin D helps your bones to absorb calcium.   Sources of Calcium For Bone Health Here’s a quick list of what foods provide the  calcium your bones need:  
                    
                      | Food Type | Serving Size | Calcium Content |  
                      | Milk | 1 cup | 30% |  
                      | Cheeses | 1 oz | 20% - 30% |  
                      | Yogurts | 8 oz | 30% - 40% |  
                      | Sardines, salmon | 2 oz | 20% |  
                      | Broccoli | ½ cup | 5% |  
                      | Spinach | ½ cup | 10% |  
                      | Almonds | 1 ounces | 7.5% |  
                      | Muffin | 1 | 10% |  
                      | Cheerios | 1 oz. | 5% |  
                      | Dried Beans | ½ cup cooked | 5% |  The % shows how many milligrams of calcium a food has – this is  way food labels show calcium content.  So  if 1 cup of milk has 30% calcium, it just means that it has 300mg of  calcium.  Here are some foods that  provide other essential nutrients for your bones: Zinc – oysters, meat, beans, and grains.Copper – grains, liver, shellfish, oysters, poultry, vegetables,  nuts.
 Magnesium – grains, green vegetables, meat, milk.
 Boron – fruits, green veggies, nuts.
 Do you see a common theme here?   Veggies, grains, and dairy products contain a majority of the essential  nutrients your bone (and other parts) need.   I hate keeping track of what I eat all the time, and I don’t – it’s such  a hassle.  But I know that I get the  appropriate amounts of nutrition just by eating a lot of these high nutrition  foods like veggies, grains, dairy products, and limited meat.   So if you’re lazy like me, and don’t want to measure out food  servings for every meal, just make sure you serve variety of foods that are  high in nutrition. Calcium Requirements People at different ages require different amounts of  calcium.  Here’s a general guide you can  use: 
                    
                      | Age | % Calcium | mg Calcium |  
                      | 0 to 12    months | 21% | 210mg |  
                      | 1 to 3    years | 27% | 270mg |  
                      | 4 to 8    years | 50% | 500mg |  
                      | 9 to 18    years | 130% | 1300mg |  
                      | Adults 19    to 50 | 100% | 1000mg |  
                      | Based on the Dietary Reference for calcium from National    Academy of Sciences |  Healthy Bones - Quit Smoking and DrinkingSmoking and drinking affects your health on all levels. Smoking increases your body’s rate of bone loss.  Studies have shown that smokers and drinkers  lost bone mass twice as fast with those who smoke or drink less.  Liquor also reduces your bone density over a  long period of time. |
