Scientists provide the clue, and you can now complete the

The February 14, 2002 issue of the New England Journal of
Medicine (Volume 346:476-483, Number 7) contains a study
proving that the risk of Alzheimer's Disease doubles for
those people with the highest levels of homocysteine in
their bloodstreams.

Neurologists at the Boston University School of Medicine
obtained blood samples from 1092 elderly healthy subjects
over an eight year period. During the course of the study,
111 of those subjects developed dementia, diagnosed as
Alzheimer's Disease.

Those who developed Alzheimer's had enormous increases of
homocysteine in their blood when compared to those who did
not develop dementia.

There are 28 amino acids in nature. Your body's liver
manufactures 19 of them. The other 9 are called "essential",
which means that they must be obtained in the foods you eat.
Methionine is one such "essential" amino acid. I have
previously written about homocysteine and methionine. After
ingestion, methionine converts to homocysteine.

Homocysteine has been linked to heart disease by William
Castelli, senior investigator of the largest clinical heart
study in history, the Framingham Study. Dairy causes heart
disease. See:

Homocysteine has also been linked to osteoporosis. Ingestion
of sulfur-containing amino acids causes an acid condition in
the bloodstream which the body neutralizes by leeching
calcium from bones. See:

Animal proteins contain greater amounts of methionine than
do plant proteins. Milk is liquid meat, and dairy products
contain high levels of methionine, which has sulfur as its
center atom. The sulfur converts to sulfates and causes an
acid condition in the blood that results in cellular

Here are some values of methionine for 100 gram portions of
various foods. You will find that a result of eating meat or
consuming dairy products is the creation of a methionine-
rich, and subsequent homocysteine-rich environment of
Alzheimer-causing substances human blood serum.

Cow's milk = .083 grams of methionine
Soy milk = .040 grams
Mori-Nu silken soft tofu = .074 grams
Chicken (broiled breast meat, no skin) = .859 grams
Swiss cheese = .784 grams
Parmesan cheese = .958 grams

Cow's milk contains twice as much methionine as does soy
milk. Chicken has nearly 12 times the amount of methionine
as does tofu, and Parmesan cheese has an unlucky 13 times
more methionine than does tofu.

The neurologists who conducted this study did not consider
how or why people have high levels of methionine. Pity. They
were close to determining the cause and cure of Alzheimer's.

These neurologists who published the study in the New
England Journal of Medicine suggest that folic acid reduces
levels of homocysteine. Folic acid can be found in green
leafy vegetables, grains, and fruits, particularly citrus.
However, the best cure may very well be to not eat what
causes the problem.

Scientific research has provided the proof that Alzheimer's
Disease can be controlled or prevented by eliminating the
standard American diet that includes milk and dairy products
as its foundation.
