Calcium in diet

Calcium in diet
Calcium is the most abundant mineral found in the human body, with teeth and bones contain the most calcium (about 99%). Body tissue, neurons, blood and other body fluids contain the remaining calcium.Alternative Names

Diet and calciumFeatures
Calcium is one of the most important minerals for growth, maintenance and reproduction of the human body and helps form and maintain healthy teeth and bones. Proper levels of calcium over a lifetime can help prevent osteoporosis.
Calcium helps with blood clotting, nerve signaling, relaxation and muscle contraction, as with the release of certain hormones. It is also necessary for normal heartbeat.Food Sources
Many foods contain calcium, but dairy products are the most significant source. Milk and dairy products such as yogurt, cheese, butter contain a type of calcium assimilated more efficiently.
Children aged between 1 and 2 years are recommended whole milk with 4% fat. The fat content of dairy products is a concern for adults and children over two years old. The fat content of dairy products can easily be reduced while maintaining the calcium content, choosing skim milk and other dairy products low in fat (2% or 1%).
Calcium is not the "fat portion" of milk, so removing the fat will not affect the calcium content. In fact, when you replace the fat portion that has been extracted by an equivalent amount of skim milk, you are actually increasing the calcium content. Therefore, a cup of skim or nonfat milk has more calcium than whole milk rate because it is composed of calcium-containing portion.
Other dairy products such as yogurt, most cheeses and butter are excellent sources of calcium and presentations are available free or low fat.
Milk is a good source of phosphorus and magnesium, which help the body absorb and use calcium more effectively. Vitamin D is essential for the efficient utilization of calcium, which is why milk is fortified with this vitamin.
Green leafy vegetables such as broccoli, kale, kale, mustard, turnips, and bok choy or Chinese cabbage are good sources of calcium.
Other sources of calcium include salmon and sardines canned with their soft bones. Shellfish, almonds, Brazil nuts and dried beans are also sources of calcium. However, it is difficult to eat adequate amounts of these foods to achieve optimal calcium intake.
Some foods such as breads and orange juice are fortified with calcium, to make them a significant source of calcium for persons who do not consume many dairy products.Side Effects
Normally, increased calcium intake during limited periods does not cause side effects, but the fact of receiving a large amount of calcium over a period of time raises the risk of kidney stones in some people.
People who do not receive enough calcium over a period of time can develop calcium deficiency, a condition that leads to osteoporosis, loss of jaw bone (osteonecrosis), hypertension and other disorders.
People with lactose intolerance have trouble digesting lactose, the sugar in milk. However, there is availability of OTC products to make it easier to digest lactose and can also buy lactose-free milk at most grocery stores.
Very rarely, some people have a true allergy to milk protein. Such persons must avoid all dairy products and need to take calcium supplements.Recommendations
Recommendations for calcium intake to vary depending on the age and needs of each person. In general, adults should get 1,200 milligrams (mg) of calcium per day. The total calcium intake to 2000 to 2500 milligrams per day from dietary sources and supplements appears to be safe. The best source of calcium are foods rich in this mineral, such as dairy products.
The following list can help determine how much calcium you are getting from food:

    1 cup milk 8 ounces = 300 milligrams of calcium
    2 ounces of Swiss cheese = 530 milligrams of calcium
    6 ounces of yogurt = 300 milligrams of calcium
    2 ounces of sardines with bones = 240 milligrams of calcium
    6 ounces cooked turnip greens = 220 milligrams of calcium
    3 ounces of almonds = 210 milligrams of calcium
Vitamin D is needed to help the body absorb calcium, which is why, when selecting a calcium supplement, look for ones that also contain this vitamin.
