Food sources of calcium

Calcium is a mineral that helps human body build and maintain strong bones and teeth. Calcium is the most abundant divalent cation of the body, representing about 1.5% to 2 % of total body weight.

Calcium in the body roses from an average of 24 grams at birth to about 1300 grams at maturity. Over 99% of the total calcium of the body located in the bones, where it accounts for 39% of the total body bone mineral content and in the teeth, mostly as hydroxyapatite.

The amount of calcium human body need depends on age, but women age 50 and younger and men ages 70 and younger both need about 1,000 milligrams daily.
Calcium is present in foods and dietary supplements as relatively insoluble salts. Food sources of calcium include milk, milk products, sardines, clams, oysters, turnip greens, broccoli, legumes and dried fruits. Broccoli is one of the healthiest vegetables. 100 grams of raw broccoli contains 46 milligrams of calcium, while the same amount of cooked broccoli contains slightly less (40 milligrams).

Majority of dietary calcium in industrialized countries comes from milk products. Milk and milk alternatives are excellent sources of calcium. Products like milk, yogurt, and cheese are rich in calcium and tend to be the best-absorbed sources of it.

When substantial amounts of grains are consumed, for like breads or as maize, these can be important sources, although the calcium in cereals rends to be less bioavailable than that in dairy products.

Orange juice and cereals are often fortified with calcium. Calcium citrate malate is a well-absorbed form found in some fortified juices. There are also fortified cereals that provide as much as 100 mg of calcium per serving.
