Bone-Up On Calcium
According to the U.S. Department of Agriculture, about sixty percent
of teenage boys and eighty percent of teenage girls do not get enough
calcium in their diets. Not having enough calcium can result in a big
problem for them in later years, because it can put them at higher
risk of developing osteoporosis. This can be further aggravated by
excessive soft drink consumption. These carbonated drinks contain
phosphoric acid which can "leach" calcium from bones. Most
individuals experience an increase in bone density up to about age
thirty, but the majority of this increase takes place by age twenty.
This is one important reason why young people need to obtain adequate
levels of calcium.
The National Osteoporosis Foundation recommends that adults obtain
from 1,000 to 1,500 milligrams of calcium every day. However, adults
are falling behind, too, with between only 500 to 700 milligrams per
day, as low as one-third the amount needed to stay healthy.
Adding more calcium to your diet can significantly help your body
maintain healthy function and structure not only now, but in later
years as well. Of course, supplements are helpful and eating foods
that contain calcium is important. For instance, three servings of
dairy products can provide about 1,000 milligrams of calcium. This
would amount to three cups of milk or yogurt, five ounces of cheese,
or five cups of ice cream. Broccoli, cabbage, carrots, and tofu are
other good vegetable sources of calcium.
Calcium May Cut Colon Cancer Risk
Dr. Peter Hold of St. Luke's-Roosevelt Hospital in New York recently
completed a study, paid for by the National Dairy Council, in which
he followed seventy patients at risk for colon cancer for one year.
Half of the remained on their existing diet and the other half
increased their calcium intake of low-fat dairy foods to about 1,500
milligrams per day. The results of his research, published in the
Journal of The American Medical Association (JAMA) 1998;
280:1074-1079, show that the group which ingested the additional
calcium was at less risk of developing colon cancer.
Laid Up? You're Probably Losing Bone
When you're confined to bed, whether you're recovering from a lengthy
illness, or just a case of the flu, your body begins losing bone
after just one day, according to calcium expert Robert Heaney, M.D.,
of Creighton University in Omaha, Nebraska. While it's difficult to
prevent this loss, it can be replaced by taking extra calcium. How
much is enough? An extra 500 milligrams per day for a week for every
day spent in bed, advises Heaney. For a woman, this amounts to a week
of 2,000 milligrams of calcium per day for each day of bed rest (as
compared to National Institutes of Health's recommendation of 1,500
milligrams of calcium per day for older people). Environmental

Calcium Versus Fat
Most Americans, especially women, don't get enough calcium to cut
their risk of osteoporosis, which results in brittle bones later in
life. In addition to taking calcium supplements, you should eat
cruciferous vegetables like broccoli, cabbage and cauliflower, or
certain root vegetables such as carrots, which are high in calcium.
Most dairy foods are loaded with calcium, but they can also be loaded
with saturated fat as well. Make sure you consume reasonable amounts
and consider choosing low-fat dairy products.
