Did you know that calcium is the most abundant mineral in the body? Most of us know that we need to consume foods that are good sources of calcium for strong bones and teeth, to help muscles contract, as well as, to keep our arteries and veins open, allowing blood to flow freely through the body.
So, who decides how much is the right amount of calcium?
The recommended daily intakes for calcium are found in the Dietary Reference Intakes (DRIs) developed by the Institute of Medicine (IOM) of the National Academy of Sciences. Dietary Reference Intake (DRI) is the broad term for a set of reference values used for advising nutrient intakes of healthy people. The Recommended Daily Allowance (RDA), which is a part of the DRIs, recommends the average daily intake that is "sufficient to meet the nutrient requirements of nearly all (97-98%) healthy individuals in each age and gender group."
Getting enough calcium from food and beverages each day is important. The recommendation for adults is to consume 1,000 milligrams per day. Teens need a little more, about 1,300 milligrams per day. MyPyramid.gov recommends teens and adults consume 3 cups of milk/dairy products each day. Calcium-rich foods are found in dairy products, dark green vegetables, soft-boned fish and calcium fortified foods like orange juice with added calcium.
Take a look at the following table to see what foods you can eat to get your daily calcium needs met:
|Yogurt, plain, low fat, 8 oz||415 mg|
|Sardines, canned in oil w/ bones, 3 oz||324 mg|
|Cheddar cheese, 1 ½ oz shredded||306 mg|
|Spinach, cooked, 1 cup||120 mg|
|Milk, nonfat, 2% or whole, 8 oz||300 mg|
|Calcium fortified orange juice, 6 fl oz||250 mg|
