Dear Doctor, 

Last month we butchered a favorite sacred cow of the health food
industry - soy foods.  We would much rather devote these Letters to
expanding your awareness of the benefits of achieving metabolic balance
through the NUTRI-SPEC objective testing system - but the soy monster
has become so big, and is attacking so many of your patients, that we had
to devote whatever space was necessary in this Letter to refute the
heavily hyped and mega financed misinformation campaign promoted by
the quacks and charlatans of the health food industry. 

You learned last month that:

1.  Soy is not a source of protein, but is actually a source of protein 
      destruction.  

2. Soy is not cancer protective, but rather, will often cause cancer.  

3. Soy is a phyto-endocrine disrupter which potentiates the toxic effects
of estrogen, accelerates aging, exacerbates cardiovascular disease,
contributes to osteoporosis, causes fibrocystic breast disease and breast
cancer, inhibits the thyroid, and elevates cholesterol.  

4. Soy is not (contrary to the health food industry myth) a staple in Asian
diets, but is used only in small quantities as a condiment. 

5. Soy inhibits the absorption of essential nutrients such as calcium,
magnesium, and especially zinc. 

6. Soy foods cause enlarged organs, particularly the pancreas and thyroid
gland, as well as increased deposition of fat in the liver.  

So -- to complete our roasting of the disgusting and dangerous soybean,
let us read on ...

The health food industry promotes soy foods as helping to prevent
cancer.  It is true that some of the substances isolated from fermented soy
foods such as isoflavone aglycones as extracts have shown
anti-carcinogenic activity in laboratory tests.  However, no studies have
shown any anti cancer effect of a high soy food diet.  But, it doesn't
matter anyway, since these isoflavone aglycones are destroyed in soy
products such as tofu and soy milk.  Furthermore, there are many actual
carcinogens that have been isolated from soy.  Some evidence exists that
the rapid increase in liver and pancreatic cancer in Africa is due to the
introduction of soy products there.

carcinogenis"   Cancer Research 1987 March 1;47(5):1333-8. 


One other damaging effect of the extreme chemical processing, high
temperature, high pressure and hot air spray processing that soy
under-goes is that the fatty acids are made rancid.  Not only are the soy
oils made rancid in the processing, but hexane and other solvents which
are used to extract the oil from the soybeans remain as traces in soy
foods.           


There is a ton of easily found information on the damaging effects of soy
in terms of its estrogen content.  Here are just a few references of
hundreds we could give you on the toxic estrogenic effects of soy.

This study showed gross cystic disease fluid protein concentration in
response to soy.  Furthermore, there was breast hyperplasia in seven out
of twenty four women during the months they ate soy.  

Hilakivi-Clark, et al.  "Maternal genistein exposure mimics the effects of
estrogen on mammary gland development" Oncology Reports 1998
May/June 5(3)609-16. 

This study showed that both human and animal data indicate that high
maternal estrogen exposure from soy during pregnancy increases breast
cancer risk among daughters.  It was also concluded that genistein acts as
an estrogen in utero, and may increase the incidence of mammary tumors
if given to a pregnant mother. 


The other gland that is devastated by bean consumption in general, and
soybeans in particular, is the thyroid.

Hypo-metabolic symptoms such as malaise, constipation, sleepiness, as
well as goiters appeared in half the subjects after taking soy beans for
three months.

Food allergies to soy are extremely common.

Here is one for good measure that popped up with my soy search which
refutes another health food industry myth -- the purported benefits of flax
seed.      

Obermeyer, et al.  "Chemical studies of phyto-estrogens in related
compounds"  Proc soc exp bio med 1995 Jan 208(1):6-12.  

This study showed that flax seed contains damaging levels of
phyto-estrogens every bit as bad as soybeans.  

One of the most pernicious uses of soy is as the main ingredient of
soy-based infant formulas.  This one cannot be blamed on the health food
industry, as it has been a standard practice of Agri Business (to unload
the by-products of soy produced for soy oil) for 50 years in America. 
Along with trypsin inhibitors, these formulas have a high phytate content
which has been shown to cause zinc deficiency in infants.  Aluminum
content of soy formula is ten times higher than milk based formula, and
one hundred times higher than unprocessed milk.  Aluminum has a toxic
effect on the kidneys of infants, and has been implicated as a causative
factor in Alzheimer's Disease in adults.              

Soy milk formulas are often given to babies with a milk allergy, but the
truth is that allergies to soy are just about as common as those to milk. 
Soy formulas are also totally deficient in cholesterol, which is an
absolute essential for the development of the infant's brain and nervous
system.  Soy formulas also have no lactose and galactose, the milk sugars
that are equally important in the development and function of the infant's
nervous system.

There is a brochure put out by the Weston A. Price Foundation
(website:www.WestonAPrice.org) which gives many additional facts to
shoot down the soy myth.  First, their literature confirms that Asians do
not consume large quantities of soy foods.  Average consumption of soy
foods in Japan and China is 10 grams (about 2 teaspoons) per day. 
Asians consume soy foods in small amounts as a condiment, and not as a
replacement for animal foods. 

They also confirm the damage done by left-winged socialist
internationalist bureaucrats in America and Europe that have force fed
soy foods to developing nations in the name of preventing starvation, and
saving the planet from eating "too much" meat, poultry and eggs.  In 
third world countries, soybeans have been forced down the people's
throats as a replacement for their traditional crops and natural, healthful
foods.  Meanwhile, the only real beneficiaries of this left-winged lunacy
are the multi-national Argi-Business corporations who grow the soy crop
(which requires tremendous amounts of herbicide, creating toxic run-off
-- a tragedy which the environmentalists choose to ignore.)  

The Price Foundation literature also does a nice job of attacking the use
of soy formula for infants.  They point out the damage from the trypsin
inhibitors that destroy protein and affect pancreatic function; they show
that such a diet leads to stunted growth; they show that soy foods
increase the body's requirement for vitamin D and thus decreases bone
mineralization and growth; and, they show that the reduced availability
of iron and zinc damages the development of the infant's brain and
nervous system, as does the lack of cholesterol in soy formula.  

The literature also points out that the outrageous doses of phytoestrogens
in soy formula have been implicated in the current trend toward
increasingly premature sexual development in girls, and the delayed or
retarded sexual development in boys.  This is a fascinating subject about
which you and your patients must be aware.  

Babies fed soy-based formula have 13,000 to 22,000 times more estrogen
compounds in their blood than babies fed milk-based formula. 

Infants exclusively fed soy formula receive the estrogenic equivalent of
at least five birth control pills per day. 

Male infants undergo a "testosterone surge" during the first few months
of life, when testosterone levels may be as high as those of an adult male. 
During this period, baby boys are programmed to express male
characteristics after puberty, not only in the development of their sexual
organs and other masculine physical traits, but also in setting patterns in
the brain characteristic of male behavior. 

Pediatricians are noticing greater numbers of boys whose physical
maturation is delayed, or does not occur at all, including lack of
development of the sexual organs.  Learning disabilities, especially in
male children, have reached epidemic proportions. 

Soy infant feeding  -- which floods the bloodstream with female
hormones that inhibit testosterone -- cannot be ignored as a possible
cause for these tragic developments.  In animals, soy feeding indicates
that phytoestrogens in soy are powerful endocrine disrupters. 

Almost 15 percent of white girls and 50 percent of African-American
girls show signs of puberty, such as breast development and pubic hair, 
before the age of eight.  Some girls are showing sexual development
before the age of three.

Premature development of girls has been linked to the use of soy formula
and exposure to environmental estrogen-mimickers such as PCBs and
DDE.

A high intake of phytoestrogens during pregnancy may have adverse
affects on the developing fetus and the timing of puberty later in life.
Many people (vegetarians in particular) delude themselves into thinking
that soy foods are a vegetarian source of vitamin B12.  Nothing could be
further from the truth.  As the Price Foundation literature points out,
vitamin B12 is not absorbed from plant sources, and modern soy products
actually increase the body's needs for vitamin B12. 

Soybeans:  Chemistry and Technology Vol. 1, 1972. 

The Price Foundation also points out that many people delude themselves
into thinking that since soy foods contain phytoestrogens,  they can help
prevent osteoporosis.  Again, this is opposite to the truth.  When we give
you a complete report on the toxic effects of estrogen, you will see that
estrogen actually causes osteoporosis -- it does not prevent it.  But, as
regards soybeans, soy foods, in addition to their estrogenic effect, can
cause deficiencies in calcium and vitamin D which we all know are
needed for healthy bones.  It is also pointed out that the calcium form
bone broth, and the vitamin D from sea food, lard, and organ meats, is
what prevents osteoporosis in Asian countries -- not the little bit of soy
foods they consume.  

You will also see a brief summary of the hormone disrupting effects of
soy foods in the Price Foundation Brochure (they use many of the same
references that we have already given you).  Soy isoflavens are
phyto-endocrine disrupters.  At minimal dietary levels  they can prevent
ovulation and stimulate the growth of cancer cells.  Eating as little as 30
grams (about 4 tablespoons) of soy per day can result in hypo-thyroidism
with its lethargy, constipation, weight gain, and fatigue.  

They go on to point out that soy foods can stimulate the growth of
estrogen-dependent tumors, and cause thyroid pathology, particularly in
association with menopausal difficulties.  Furthermore, women with the
highest levels of estrogen in their blood had the lowest levels of cognitive
function.  In Japanese Americans, tofu consumption in mid-life is
associated with the occurrence of Alzheimer's Disease in later life.  

Furthermore, numerous animal studies show that soy foods cause
infertility in animals.  Soy consumption enhances hair growth in middle
age men, indicating that it decreases testosterone levels.  Tofu was
consumed by Buddhist Monks to reduce libido.  

So, Doctor,  we have not even gotten a fraction of the way through all the
literature on the damaging effects of soy, and we have already 
probably reached the point of over-kill.  Do yourself a big favor -- stay
off the soy; keep your family off the soy; warn all your patients about
soy; and give each patient the diet that objective tests show is ideal for
his or her metabolic type.  

Sincerely,
