Calcium is the most plentiful
mineral found in the human body, accounting for 1.5% to 2% of an adult's
total body weight. The teeth and the bones contain the majority of the
body's calcium (about 99%). Calcium in these tissues is concentrated
in the form of calcium
phosphate salts. Nerve cells, body tissues, blood,
and other body fluids contain the remaining calcium.
Calcium is one of the most important
minerals for the growth, maintenance, and reproduction of the human
body. Calcium is essential for the formation of and maintenance of healthy
teeth and bones.
The
bones incorporate calcium into their structure. Like other tissues in
the body, bones are continually being reabsorbed and re-formed. Teeth
incorporate calcium in their structure in a manner similar to bones.
Calcium
has other functions in addition to maintaining healthy teeth and bones.
Blood coagulation, transmission of nerve impulses, muscle contraction
and relaxation, normal heartbeat, stimulation of hormone secretion,
activation of enzyme reactions, as well as other functions all require
small amounts of calcium.

Food Sources
Many foods contain calcium, but
dairy products are the most significant source. Milk and dairy products such
as yogurt, cheeses, and buttermilk contain an efficiently absorbed form of
calcium.
For children between the ages
of 1 and 2 years old, whole milk (4%) is recommended. The fat content of dairy
products is a concern for adults and children over the age of two. You can
easily reduce the fat content of dairy products while maintaining the calcium
content by selecting low-fat (2% or 1%) or skim milk.
The calcium is not contained
in 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 removed with
an equal part of skimmed milk, you are actually increasing the calcium content.
Therefore, one cup of skim or non-fat milk will have more calcium than one
cup of whole milk because almost the entire cup of skim milk is the made up
of the calcium-containing portion!
Other dairy products such as
yogurt, most cheeses, and buttermilk are excellent sources of calcium and
are available in low-fat or fat-free versions.
Milk is also a good source of
phosphorus
and
magnesium,
which help the body absorb and use the calcium more effectively.
Vitamin D
is essential for efficient utilization of calcium. Milk is fortified with
vitamin D for this reason.
Green leafy vegetables such as
broccoli, collards, kale, mustard greens, turnip greens, and bok choy or Chinese
cabbage are good sources of calcium. Certain green vegetables are less effective
sources of calcium. While their calcium content appears to be high, their
fiber and oxalic acid content interferes with the absorption of calcium.
Other sources of calcium are
salmon and sardines canned with their soft bones. Shellfish, almonds, Brazil
nuts, and dried beans are also sources of calcium. It is difficult, however,
to eat adequate quantities of these foods to achieve optimal calcium intake.
Several food products, such as
breads and orange juice, are enriched with calcium to make them a significant
source of calcium for people whose dairy product consumption is inadequate.

Side Effects
Increased calcium intake for
limited periods does not normally cause toxic effects. The urine and the feces
easily eliminate any excess calcium. However, an increased risk of kidney
stones in persons susceptible to them has been associated with chronically
high calcium intake.
Low intakes of calcium for prolonged
periods of time can lead to calcium deficiency. This condition leads to osteoporosis,
loss of the jaw bone (and secondary oral health problems), hypertension, and
other disorders.
Persons with lactose intolerance
have trouble digesting lactose, the sugar in milk. Lactose intolerance is
due to an inability to produce lactase, the enzyme that digests milk sugar.
The wall of the gastrointestinal tract normally produces this enzyme. In some
people, due to diseases of the gastrointestinal tract or to hereditary factors,
this enzyme cannot be produced by the body. Fortunately, lactase can
be synthetically produced and bought in various over-the-counter formulations,
and taken orally with milk to aid in its digestion. You can also buy lactose-free
milk at most grocery stores.
In rare instances, some people
have a true allergy to the protein in milk. This condition requires restriction
of all dairy products. These individuals may have trouble obtaining enough
calcium in their diet and may need to take calcium supplements.

Recommendations
Calcium recommendations vary
depending on age and special needs. In addition, levels of estrogen can affect
calcium needs in women.
Vitamin D is required for adequate amounts of calcium to be absorbed into
the body, and for adequate calcium levels to be maintained. Therefore, when
choosing calcium supplements, those that also contain the RDA of
vitamin D
are preferred.
Comparing the RDA to the food sources of calcium helps to put the RDA in perspective:
-
8-ounce glass of milk = 300
milligrams
-
2 ounces of Swiss cheese =
530 milligrams
-
6 ounces of yogurt = 300 milligrams
-
2 ounces of sardines with bones
= 240 milligrams
-
6 ounces of cooked turnip greens
= 220 milligrams
-
3 ounces of almonds = 210 milligrams
A total intake of up to 2,000
milligrams per day from dietary sources and supplements appears to be safe.
The preferred source of calcium is calcium-rich foods such as dairy products.
The FDA's
reference
daily intakes (RDI) for Calcium is 1.0 gram
(g).
