Calcium Magnesium and why we need it
Calcium is a part of many vital biological processes in your body. It
plays a role in maintaining a healthy heartbeat and regulating
neurotransmitters necessary for brain functions. About 99 percent of the
body's calcium is stored in bones and teeth, and your body will
"borrow" the stored calcium from bones as necessary for its myriad
purposes. Calcium's most well-known function is its role in bone
formation.
CALCIUM NEEDS
Those with the greatest calcium needs are young people, pregnant women
and seniors. Children and adolescents have a higher need of the mineral
because their bones and teeth are still forming or growing. Pregnancy
engenders a higher calcium need for the skeletal development of the
fetus, and pregnant women may require additional calcium to offset their
own bone loss, the "Journal for Perinatal Education" reports. Seniors
may need more calcium to prevent osteoporosis.
DEFICIENCIES
A deficiency in calcium, also known as hypocalcaemia, can cause problems
ranging in seriousness from numb and tingling fingers to cardiac
arrest. A long-term deficiency is particularly damaging and is
associated with mental retardation and skeletal abnormalities. A chronic
deficiency can also lead to losing significant amounts of calcium from
bones, leaving them weak and more susceptible to fracture.
FOOD SOURCES
Dairy products are a good source of easily absorbed calcium and include
milk, cheese, yogurt and sour cream. Many people are lactose intolerant,
however, in which case soy milk fortified with calcium can be
substituted. Many store-bought foods are now calcium-fortified,
including many breakfast cereals and some brands of orange juice. Salmon
is high in calcium, as are most meats, and calcium is also in spinach,
peanuts and almonds. Or buy the supplement direct on my website here:- Calcium Magnesium
