They're Taking The Joy Out Of Soy

I'm concerned about the author`s denial that unfermented soy is the cause of pancreatic cancer;

in this, part III, I critique the author`s referencing of the FDA,

here:

According to an FDA scientific review, soy does not cause pancreatic cancer .

Epidemiological studies do not confirm that soy increases the prevalence of thyroid disorders

. anything the FDA has to say about soy should be taken with this grain of salt:

www.westonaprice.org/.../soy_studies.html

1999 Food Labeling: Health Claims: Soy Protein and Coronary Heart Disease,

Food and Drug Administration 21 CFR Part 101 (Docket No. 98P-0683)

. This US government document allows a health claim for foods containing 6.25 grams of soy protein per serving

. The original petition, submitted by Protein Technologies International (a division of Dupont),

requested a health claim for soy`isoflavones,

based on assertions that

"only soy protein that has been processed in a manner in which isoflavones are retained

will result in cholesterol-lowering."

In 1998,

the FDA made the unprecedented move of rewriting PTI's petition,

removing any reference to the phytoestrogens

and substituting a claim for soy protein,

a move that was in direct contradiction to the agency's regulations.

(The FDA is authorized to make rulings only on substances presented by petition) .

The abrupt change in direction was no doubt due to the fact that

a number of researchers, including USA.gov scientists,

submitted documents indicating that isoflavones are toxic .

Many of their protests expressed concerns about enzyme inhibitors,

and a tendency to cause goiters, and endocrine disruption .

I'm concerned about the author`s denial that unfermented soy is the cause of pancreatic cancer;

here, in part II, I give my critique:

. the author`s sources appear to contradict each other:

is it true that Japanese eat far more soy and yet have more pancreatic cancer or not .

. is the soy useage quoted by <Cancer Research 49: 499-502, 1989> fermented?

. at this source: jjco.oxfordjournals.org/.../283

it is found that over the the past 4 decades,

japanese rates of pancreatic cancer have been steadily increasing,

whereas, usa` rates have remained relatively constant,

so that by 2000, they were having equal rates .

. it is undisputed that the Japanese soy consumption was primarily

fermented or low-dosage many decades ago;

and, that fermenting or lowering the dose of soy detoxifies it .

. here is some telling history

of how industrialization is able to increase asia`s consumption:

www.soyinfocenter.com/chronologies_of_soyfoods-soymilk.php

1950's

- Soymilk enters the modern era

as it begins to be marketed in bottles like soft drinks,

1954

- Japan's first commercial soymilk, sold in bottles,

is introduced by the Ueda Tofu Shop in Hachioji, Tokyo.

1960s

- In Japan, soymilk slowly increases in popularity

. New manufacturers are: Nihon Tanpaku Kogyo (1962).

College Health Foods (later renamed San-iku Foods) in Chiba Prefecture with its Soyalac,

Luppy Tanpaku (House Shokuhin) in Saitama Prefecture with its Luppy soymilk (1969).

1967

Japanese Children Enjoying Soymilk:

- Soymilk begins to be packaged to be sold without refrigeration

1970's and 1980's

- Soymilk becomes a popular beverage throughout Asia,

spreading to Europe, Australia and the United States.

. I'm concerned about the author`s denial that unfermented soy is the cause of pancreatic cancer;

here, in part I, is my summarization of the author`s argument:

Sally Fallon and Mary E. Enig, from the Weston A. Price Foundation

write that

soy contains anti-nutrients and toxins;

until a few decades ago, soy was considered unfit to eat, even in Asia .

. They admit most of the growth-depressants in soy

are removed in processing and fermentation,

but not completely eliminated .

. they claim that the Japanese and Asians eat 30 times more soy than North Americans,

and the Japanese have higher rates certain types of cancer [related to soy,

particularly] thyroid, and pancreas .

. they claim the enzyme inhibitors in soy cause pancreatic cancer;

they cite the work of Mark Messina, author of

The Simple Soybean and Your Health [Avery Publishing 1994],

. they claim that Messina purposely left out a 1985 study by Rackis

which showed that soy increases the risk of pancreatic cancer in rats.

[Advances Experimental Medicine Biology 199: 33-79, 1986]

. while the enzyme (protease) inhibitors in soy protein

increase the weight of the pancreas,

they do not appear to produce lesions, abnormal growths or DNA abnormalities among rats.

[Journal Nutrition 117: 247-52, 1987]

At a workshop conducted by the National Cancer Institute,

researchers pointed out that the pancreas of a few species of animals, notably rats and chicks,

are extraordinarily sensitive to dietary protease inhibitors as found in soy

. This effect has not been demonstrated in other species such as hamsters, mice, dogs, pigs, and monkeys

and is "not expected to occur in humans," says the report

. Human populations that consume high levels of soy

exhibit decreased rates of pancreatic cancer. [Cancer Research 49: 499-502, 1989]
