The
Weston A. Price Foundation, a non-profit nutrition education foundation,
is urging the Food and Drug Administration (FDA) to deny a petition
that would allow soy products to claim they prevent cancer. They say
the petition by Solae, a manufacturer of soy protein and other processed
soy products, omits many studies indicating soy may cause cancer.
The FDA will make the decision regarding the petition later this
year. If passed, the manufacturer could label their soy products
as cancer fighters to influence consumers buying decisions. Many
experts say Solae was "highly selective" in choosing the
evidence they submitted to the FDA, emphasizing favorable outcomes
when results were inconclusive and leaving out studies that suggest
soy protein can contribute to, and even cause and accelerate, cancer.
Solae would make a lot of money off of the cancer health claim.
As Sally Fallon, president of the Weston A. Price Foundation, points
out:
"Since the FDA authorized the Soy Protein and Coronary Heart
Disease Health Claim, per capita consumption of soy protein increased
from 0.78 g/day in 1998 to 2.23 g/day in 2002. Solae predicts that
consumption of soy protein will double with a cancer health claim.
Solae stands to reap tremendous financial gain at the expense of
the public."
Even FDA scientists have warned of the cancer-causing effects of
soy and the dangers of consuming too many soy foods. And according
to the British Committee on Toxicity (COT), who reviewed much of
Solae's evidence, the results were "inconsistent and contradictory."
They point out that soy foods have been linked to an increased risk
of prostate cancer and have caused changes to the brain.
Other misleading claims mentioned by the
Weston A. Price Foundation include:
-
Solae claims that soy protein prevents gastrointestinal cancer,
yet this is contradicted by numerous studies, Solae left out
key studies that link the soy lectin--a component of soy protein--to
precancerous conditions in the small intestines
-
Solae states that "the totality" of the evidence
supports a soy protein/cancer claim, a conclusion that was reached
via meta-analyses. Meta-analyses is easily manipulated by leaving
out studies that contradict the desired conclusion, and
-
Solae left out many of these studies
-
Solae minimized a large-scale study linking soy protein to
bladder cancer
-
Solae omitted evidence linking soy protein to thyroid and pancreatic
cancers and to childhood leukemia. Solae failed to address soy
protein's well-documented risks to the digestive, immune
and neuroendocrine systems of the body
