SOY MILK VS. COW'S MILK

Each day, one or more people send emails asking for
the differences between soymilk and cow's milk.

Let's compare 100-gram portions (3.5 ounces) of
soymilk vs. cow's milk:

Cow's milk has 61 calories. Soymilk has 33 calories.
Cow's milk contains 3.34 grams of fat. Soymilk contains
1.91 grams of fat.

Cow's milk has 14 milligrams of cholesterol and no
dietary fiber. Soymilk contains 1.3 grams of fiber
and has zero cholesterol.

Cow's milk contains a full range of amino acids.
Soymilk also contains a full range of amino acids.

Both contain plenty of protein. Cow's milk actually
only contains one-half gram more protein than the
100-gram portion of soymilk.

As for the nine essential amino acids in protein
necessary for sustaining life, cow's milk and
soy milk contain nearly identical amounts, but
cow's milk does win this one by a whisker,
containing a mere one-fifth of a gram more
essential amino acids than the soy.

That may be a hollow victory for milk lovers
because one of the nine essential amino acids is
methionine. Cow's milk contains more than twice
as much methionine as does soymilk. The center
atom of methionine is sulfur. Too much animal
protein creates an acid condition in the blood
which the body must neutralize by taking calcium
from the bones. Nations eating the most animal
protein have the highest rates of osteoporosis.
Soymilk contains greater amounts of other amino acids
including arginine, alanine, aspartic acid, and
glycine.

Arginine slows the growth of cancers by strengthening
the immune system. Alanine aids in the metabolism of
sugars. Aspartic acid increases stamina and plays a
vital role in metabolism, acting as an anti-oxidant.
Glycine is necessary for brain and nervous system
functioning and muscle/energy metabolism.

When milk is pasteurized, Vitamins A, C, and D
are destroyed. The same can be said for those
vitamins when soymilk is manufactured. Soymilk
does contain more than four times the amount of
thiamin (Vitamin B-1) and nearly twice the amount
of niacin (Vitamin B-3) as does cow's milk.

Soymilk also contains more magnesium, copper, and
manganese than does cow's milk. In order to absorb
calcium, one needs magnesium. Copper also aids in
bone formation. One early sign of osteoporosis is
a deficiency in copper. Soymilk contains twelve
times the amount of copper as does cow's milk.
Soymilk also contains 42 times the amount of
manganese as does cow's milk. Manganese
is also needed for bone formation. People with
anemia rely upon manganese for iron storage.
Trace amounts of manganese are essential for
neural transmissions, protein metabolism, and
many other body functions.
