As we stated earlier, researchers believe it is soy's rich
and unique phytochemical composition that helps make it such a powerful all-natural health
promoter, as well as a proven preventive for cancer and heart disease, the two most deadly
diseases facing mankind today.
In 1990, a group of researchers sponsored by the National
Cancer Institute identified five specific groups of phytochemicals present in soy which
exhibit profound anticancer properties. Further research has pinpointed additional
phytochemicals responsible for soy's extraordinary antioxidant and cholesterol-lowering
properties in preventing heart disease. Interestingly, some of the most powerful of all of
these phytochemicals are exclusive to soy. You won't find them in any other food!
Among the disease fighting phytochemicals found in great
abundance in soy are:
Isoflavones - These compounds are similar to
natural estrogen, but have only about 1/ 100,000 times the strength. When ingested, they
actively compete with estrogen for receptor sites on the walls of human cells. By latching
on to these vital receptor sites, they make it far less likely for an overabundance of the
more powerful estrogen hormones to bind to human cells and stimulate them into the
cancerous cycle of abnormal cell division. Overly high hormone levels in the human body
have long been associated with the onset and progression of various cancers, particularly
breast cancer in women and prostate cancer in men. But isoflavones, which are essentially
plant estrogens, are so weak, they don't have the deadly effect that the more powerful
human hormones do. In essence, isoflavones now appear to be the natural way of displacing
estrogen and other hormones, and thereby helping prevent them from stimulating cancer in
the human body. Additionally, researchers now believe that certain isoflavones found in
soybeans promote a mild estrogenic activity that radically diminishes cholesterol levels
in the bloodstream, which would explain much of soy's phenomenal cholesterol lowering
Soybeans are one of
the most isoflavone-rich foods in the entire plant kingdom, giving soy
much of its powerful anticancer and anti-heart disease properties!
Genistein - This is also a
powerful cancer-fighting isoflavone, but with very unique properties. Laboratory studies
have demonstrated that genistein actually blocks the action of enzymes that are known to
promote tumor growth, and neutralizes or inhibits tyrosine kinase, which is involved in
the transformation of normal cells into malignant cells. In essence, when you neutralize
tyrosine kinase in the human body with genistein, you stop tumor growth in its tracks!
More than 30 studies have shown that when genistein is added to cancer cells growing in
the laboratory, cancer growth grinds to a halt. According to Dr. Morton Walker, genistein
has another extraordinary' cancer-fighting ability. He states, "Genistein also causes
cancer cells to convert to normal cells by stimulating them to dedifferentiate and turn
more primitive, less specialized, and less deadly." Much like the highly-touted
cancer-fighting shark cartilage products, genistein is a potent antiangiogenetic. This
means it inhibits the growth of the tiny blood vessels needed by tumors for nourishment.
By neutralizing the substance secreted by tumors to encourage new blood vessel growth
(This substance Is called vascular endothelial growth factor, or vegF), genistein
literally causes the starvation of the tumor. In a similar way, genistein also helps
prevent heart disease. Researchers now believe it has the unique ability to block the growth of cells that
form plaque deposits in arteries, thereby preventing hardening of the arteries! Soy is the ONLY known source of
genistein in the world today. No other plant or animal SOURCE on earth contains this
powerful cancer-stopping, plaque-blocking and heart-protecting compound!
- According to Dr. Earl Mindell, these compounds effectively block the activity of a
particular group of cellular proteases which promote tumor growth [Not to be confused with
the much-to-be-desired protease digestive enzymes which are essential for the proper breakdown and
assimilation of the protein component found in many foods]. Dr. Ann Kennedy of the
University of Pennsylvania School of Medicine claims protease inhibitors are so powerful
in their anticancer properties, they may be a "universal anticarcinogen."
Protease inhibitors work to prevent or even extinguish a wide variety of cancers ranging
from liver, to colon, to breast cancer. In one recent study, a potent protease inhibitor
found in soy called BBI (Bowman-Birk Inhibitor) stifled tumor formation in 100% of the lab
animals tested, prompting researchers to speculate that BBI may be the single-most potent
anticancer compound in soy.
Phytic acid - This is a unique chelating compound that binds
with metals that promote tumor growth and subsequently excretes them from the body through
the urine. In laboratory studies phytic acid dramatically reduced the size and number of
tumors in lab animals fed a potent cancer causing agent.
Found abundantly in soy, researchers now believe phytic acid
is one of soy's chief cancer-fighting weapons.
· Saponins - Shown in animal
studies to kill colon cancer cells, these soap-like compounds have also been demonstrated
to slash high serum cholesterol levels, making them another potent "double
weapon" in soy's extraordinary disease-fighting arsenal. [Saponins also help
stimulate protein biosynthesis - necessary for all tissue repair or the body, long-term
physical endurance, muscle-building and much more.]
· Phosphatides - These are
powerful fat-emulsifying compounds which act to dissolve fats and cholesterol in the
bloodstream, thereby preventing their buildup to dangerous levels. Researchers believe
phosphatides are responsible for much of soy's extraordinary cholesterol-lowering,
