Milk’s composition is chemical maze
The solids of cow’s milk
constitute about 13 percent of
its weight. Even though milk
is a liquid, it is not a dilute
food. It is more con
centrated, for example, than
squash, cabbage, or
tomatoes. In addition to
minerals and vitamins, milk

Milk as a Source
of Calcium
Although calcium is
almost synonymous with
healthy teeth and bones, the
body’s needs for this mineral
are not confined to the years
of growth. Contemporary
research has shown that the

bones with calcium from the
diet is an ongoing process.
Calcium will be removed
from bones whether or not
this mineral is consumed in
the diet. Consequently, an
adequate supply, most
readily obtained from milk
and milk products, is
necessary to maintain
skeletal health.
Besides the maintenance
of bones, calcium performs
other functions throughout
life contraction of
muscles, excitation of
nerves, and clotting of blood.
Some segments of the U.S.
population may be deficient
in calcium. It is estimated
that three-fourths of the
calcium in our food supply is
now provided by milk.
Studies with human subjects
show that calcium from milk
is better utilized by the body
than that from vegetable
sources. In world areas
where milk is not so readily
available, it is difficult to
plan a diet to contain

calcium in the recommended
amounts.
A daily intake of 360
milligrams (mg) and 540 mg
of calcium is recommended
for infants under six months
and one year, respectively.
The allowance levels of 800
mg for children 1-10 jump to
1200 mg for the “growth
spurt” years between 11 and
18. For expectant and nur
sing mothers, the daily
calcium allowance climbs to
1200 mg; for all other adults
it is 800 mg.
Another important
mineral is phosphorus. With
calcium, it is deposited in
bone in a ratio of 1.3-2 (Ca) to
1 (P). However, the ratio
between calcium and
phosphorus in the U.S. diet
today may more nearly
approximate 1 (Ca) to 4 (P).
This may be attributable to
increased consumption of
meat, which contains
phosphorus, and soft drinks,
which contain phosphoric
acid. Of the more common
foods, milk most closely
approximates the ratio of
calcium and phosphorus
found in bones.
The Protein of Milk ...
and Its Amino Acids
Casein and lactalbumin
are the two principal
proteins in milk, with casern
being present in larger
amounts. Proteins, including
those in milk, are compased
of smaller chemical units,
the amino acids. There are
about 20 amino acids, of
which at least eight are
essential in the diet because
the body cannot produce

them in sufficient quantities.
Proteins of high nutritive
quality, such as those
present in milk, contain
these essential amino acids
in amounts balanced for use
in the body.
Lysine and tryptophan are
among the essential amino
acids abundant in milk
protein. Cereal proteins are
generally deficient in these
two amino acids. This ex
plains why milk improves
the total nutritional value of
the diet when used with
cereal foods. The high
nutritive value of milk
protein makes it of special
value in the treatment of
kwashiorkor, a type of
protein malnutrition found
among young children in
areas where people subsist
largely on plant foods.
The amount of high quality
protein in one quart of milk
supplies 34 to 67 percent of
the daily recommended
allowance of protein for the
11-18-year-olds; one pint
supplies about one-fourth to
one-third of the adult
allowance.
The Fat-Soluble
Vitamins
Fat-soluble vitamins A, D,
E, and K are present in milk
fat. Probably vitamin A is
best known; good health
requires an adequate supply
of it. If the diet is poor in this
nutrient, rough, dried
(keratinized) surface tissues
may develop in the eye
(xerophthalmia), respi
ratory tract, and skin.
