Dear Doctor,

The health food industry is at it again.  It's propaganda machines are
cranked up into high gear -- spewing out tons of garbage on the purported
health benefits of soy products.  As usual, your patients have been swept
off their feet by this heavily hyped and mega financed sales pitch.  You
are certain to have encountered the soy propaganda  yourself -- and you,
too, may have found it convincing.  After all, the health food industry is
quite adept at quoting the scientific literature selectively and out of
context.                                                                                            

It is our goal to see that all NUTRI-SPEC practitioners, and each one
of your patients, enjoys the benefits of scientific truth applied to
nutrition.   To that end, we are engaged in a never-ending battle against
quackery and charlatanism in the marketing of nutrition products.  

Until now, we in NUTRI-SPEC customer service have been dealing
with the soy foods issue on an individual basis -- enlightening each of
you as you call in with questions or comments regarding the effect of soy
on one of your patient's health, or wondering how it might fit into your
own family's nutrition regimen.  But now, since the soy issue has become
a monster of such grotesque proportions, we must deal with it in this
Letter.  

The soy propaganda machine is a perfect example of how deviously
under-handed the natural food industry can be.  There are three principle
purported benefits for which soy products are promoted -- and each one
is ludicrous.         

Soy is often included as a source of protein in health food products. 
Your patients must understand that soybeans are entirely indigestible.  To
obtain a somewhat digestible "food," the soy protein products are
severely de-natured by prolonged exposure to high temperatures, not to
mention the oxidation exposure as they are blown into a fine powder. 
Because of their difficulty of digestion, plus their extremely processed
and de-natured qualities, these are a deplorable choice as a source of
protein.

Not only is the protein in soy toxic garbage because it is so extremely de-
natured, but the soy protein is woefully incomplete as it severely lacks
the critical amino acids methionine and cysteine (and that is even before
you account for the lysine and glutamine and other amino acids that are
destroyed in the processing).  Furthermore, soy beans contain potent
enzyme inhibitors  which actually block the action of trypsin and other
enzymes needed for protein digestion.  

So -- soy as a source of protein?  You could laugh at such nonsense
except for the fact that so many of your patients have fallen for it. 

Many soy products are promoted because of the chemicals that have been
isolated from soy that are anti-cancer.  It turns out that every word that
the natural food industry says about certain substances in soy decreasing
cancer is true.  There are several substances that have been isolated from
soy that have shown a beneficial effect on a few forms of cancer -- and
this piece of truth is what the health food industry has seized upon in
their promotions.  The problem is that there are even more substances
that have been isolated from soy that cause cancer, and the health food
industry conveniently ignores that information.

The third promotional point used by the health food industry for soy
products is their estrogenic effect.  This is the most absurd notion of all. 
The phytoestrogens isolated from soy are a major problem when used
therapeutically, for the very reason that they do have estrogen activity. 
Almost all people (including both women and men) are suffering the
effects of excess estrogen -- which is a damaging stress hormone. 
Because of their estrogenic activity, these soy products accelerate aging,
exacerbate cardiovascular disease, contribute to osteoporosis, etc, etc.

We could cite countless studies from the scientific literature
demonstrating the estrogenic effect of soy, and these are some of the
same studies quoted by the health food industry.  The conclusion reached
by these researchers was that they were alarmed by the toxic estrogenic
activity of soy products.  It was demonstrated that these phytoestrogens
from soy have all the damaging affects of estrogen --  including causing
breast cancer, inhibiting the thyroid, elevating cholesterol, causing
osteoporosis, etc. 

All the health food industry did was quote out of context from these
articles showing that phytoestrogens have estrogen activity, and then
tried to peddle them to women entering menopause.  This lack of
integrity is the norm in the natural foods industry.  

(You have just as big a need for a NUTRI-SPEC LETTER addressing the
issue of estrogen damage as you do soy damage.  We'll see that you get
one in the next few months.)

One of the most common tricks employed by the health food industry in
generating propaganda on any subject is shrouding a product with a
certain mystique.  Mystery and exotica have a tremendous emotional
appeal to people -- particularly the most irrational and gullible.   Did you
ever notice how all of the "healing herbs" are only found in remote parts
of the Himalayan Mountains, or in a hidden valley in China, or in one
remote, primitive village of South America?  Why is it that none of them
grow along the highway in Peoria, Illinois?   

In that same spirit of magical mystery, a myth of soy miracles has been
contrived that attributes low cancer incidence and many other health
benefits to the Asian populations who have used soy products as a staple
in their diet for thousands of years.  This is all a lot of hog wash.  

Unlike lentils and a few other legumes that have been used for many
thousands of years as a food staple in many parts of the Orient, soy-
beans have a relatively recent history of use as a food.  Furthermore, that
use is almost entirely as a condiment, not as a dietary staple.  The
historical truth on the soybean is that it was designated by the Chinese
many thousands of years ago as one of the sacred grains -- but not
because it was eaten, but because it was used for its nitrogen fixing
properties in soil as part of crop rotation.  The soybean was deliberately
avoided as a food, as the Chinese knew of its harmful effects.                
   

It took the Chinese thousands of years to stumble across the fermentation
process that made soybeans edible (though not necessarily healthful). 
Even though the fermentation process does eliminate many of the
enzyme inhibitors in soy and also the hemaglutinin (which causes red
blood cells to clump together), these substances are not eliminated
entirely.  One way to summarize this is to say that there are a zillion
damaging effects from eating soy products, and two of those zillion (the
trypsin inhibitors and hemaglutinins) are partially eliminated by
fermentation. 

You and your patients must understand that, contrary to health food
industry propaganda, soy foods a) do not make up a large percentage of
Oriental diets, and b) do not have a long history of being consumed in
significant quantities in the Orient.

Here are some other essential facts about soy foods, with references to
back them up.  Please understand that when we talk about these negative
effects of soy foods we are not talking about phenomena that are
technically true, but quantitatively not that significant.  No -- these
damaging effects of soybeans become clinically significant immediately,
and with very small intake of soy foods. 

The phytates in a soy-based diet (again, contrary to heath food
industry propaganda) really do interfere with the uptake of important
mineral nutrients such as calcium, magnesium, and especially zinc.  The
soybean has the highest phytate content of any grain or legume. 
Furthermore, it is highly resistant to many of the phytate-reducing
techniques such as long, slow cooking.  Asian children who eat
significant amounts of tofu and soy bean curd suffer a high incidence of
rickets, stunted growth, and other developmental problems. 

People who consume tofu and bean curd and soy protein "health bars" as
a substitute for meat and dairy products risk not only protein
insufficiency, but also severe mineral deficiencies.

The extreme temperatures and pressures that must be used to break down
soybeans so that they are palatable, do extreme damage to the nutrients. 
The proteins are so severely de-natured that they become very difficult
to digest and much reduced in their biological activity.

FD-Agric V22 Oct 1971 pp526-35. 



Furthermore, the extreme processing of soy produces a carcinogen called
lysinealine, plus, reduces the content of the important amino acid cystine,
which is already lacking to an extreme in soybeans.

from soybeans"  FAO Agricultural Services Bulletin 97 Food and

Nitrosamines, which are potent carcinogens are also found in soy protein
foods, and are greatly increased during the high temperature drying
process.

In test animals, soy foods cause enlarged organs, particularly the
pancreas and thyroid gland, as well as increased deposition of fat in the
liver.

One common claim of the health food industry is that soy foods lower
cholesterol.  Quite the contrary -- in human feeding tests, soy products
did not lower cholesterol, and in fact, more often raised cholesterol
levels.

protein for animal protein in diets of hypercholesteremic Canadians"

Are you beginning to get the big idea here?  Yet to come (in next month's
Letter) is the story on how soy foods:                                     

cause cancer
cause premature aging and tissue destruction with rancid fatty acids 
poison you with hexane and other chemical solvents
cause breast cancer and fibrocystic breasts
destroy thyroid function 
inhibit brain development in infants
cause kidney damage
contribute to Alzheimer's disease
damage the pancreas
turn little boys into girls, and little girls into pathological pigs
cause osteoporosis 
destroy libido

Get off the soy!  

Sincerely,
