The Importance of Milk
in the Diet
Milk products contain high quality proteins. The whey
proteins constitute about 18 percent of the protein content
of milk. Casein, a protein found only in milk, contains
all of the essential amino acids. It accounts for 82 percent
of the total proteins in milk and is used as a standard
for evaluating protein of other foods. Protein is needed
to build and repair body tissues and to form antibodies
which circulate in the blood and help fight infection.
Milk contains nutrients such as: calcium, phosphorus,
magnesium, and potassium. The calcium found in milk is
readily absorbed by the body. Phosphorus plays a role
in calcium absorption and utilization. Phosphorus is needed
in the proper ratio to calcium to form bone. Milk provides
these two minerals in approximately the same ratio as
found in bone. Milk is also a significant source of riboflavin
(vitamin B2) which helps promote healthy skin and eyes
as well as vitamins A and D.
In adults, a calcium deficiency, along with other factors,
may result in bone deterioration called osteoporosis.
The following daily consumption of milk is suggested:
What Is Calcium?
Calcium is number one when it comes to your bones.
It helps build strong bones and teeth for such daily activities
as standing up straight, scoring that winning basket,
or even chewing on your favorite food.

What's the best way to get your daily
calcium?
Well...just think Price's dairy products. Calcium is in
lots of dairy products like Price's milk or yogurt. It's
also found in many different kinds of cheeses. Some juices,
like Price's orange juice, are even fortified (added)
with calcium. Let's not forget your veggies either! Plenty
of calcium is found naturally in dark green, leafy vegetables
like broccoli and kale. Anything made with soy, like soy
milk or tofu, is also a good source of calcium. Plus,
if you dream of Price's ice cream or frozen yogurt for
dessert, you've just discovered another tasty way to get
your calcium.
What's up with calcium?
Is there a problem with calcium? The problem is that many
people don't get enough. As time passes and people age, they
may lose the stored calcium in their bodies that helps keep their bones strong and healthy.
Their bones become less dense and more weak. If this happens,
they have a disorder called osteoporosis (say: oss-tee-oh-puh-ro-sis).
What Is Osteoporosis?
Osteoporosis occurs when too much spongy bone tissue (inside
your bones) is broken down and not enough new bone material
is made. Over time, bone is said to be "lost"
because it's not being replaced. Older people - especially
women, who are generally smaller and have bones that are
lighter and less dense - are more likely to develop osteoporosis.
There are two types of osteoporosis: primary osteoporosis
and secondary osteoporosis. Primary osteoporosis is most
common. It is usually related to age in which the older
you get, the more bone loss you are likely to have, especially
if you don't take in enough calcium.
Secondary osteoporosis is caused by diseases or other
factors that affect the body and cause bone loss, such
as:
- hormone problems, like hyperthyroidism (say: hi-per-thi-royd-is-em),
which is an overactive thyroid gland
- eating disorders, like anorexia nervosa
- taking high doses of the drug steroids for a long time
- too much smoking or drinking
