Soy May Cause Cancer and Brain Damage

Hi Elaine,

 

I suggest you do a PubMed search on isoflavoids and then research what SERMs

are.

 

The phyto estrogens from soy are NOT estrogen. They are what are called SERMs

(Selective Estrogen receptor Modifiers).

What they do is to reduce estrogen activity in breast and uterine tissue and

enhance estrogen activity in bone and brain

tissue. Too much estrogen activity in the breast and uterine tissue can boost

cancer risk, so the SERM isoflavones from

soy act to reduce estrogen activity there. Likewise too low a estrogen activity

in the bones and brain can lead to bone

density loss and brain neuron loss. Here the soy isoflavones boost estrogen's

effects. Low estrogen is highly related

to both osteoporosis and dementure.

 

Here is the PubMed search engine:

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi

 

Try doing a search on soy AND osteoporosis for example. Here is one paper you

will find:

 

====================

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve & db=PubMed & list_uids=1\

1528367 & dopt=Abstract

Menopause 2001 Sep-Oct;8(5):384-92 Related Articles, Books, LinkOut

 

 

Dietary inclusion of whole soy foods results in significant reductions in

clinical risk factors for osteoporosis and

cardiovascular disease in normal postmenopausal women.

 

Scheiber MD, Liu JH, Subbiah MT, Rebar RW, Setchell KD.

 

Departments of Obstetrics & Gynecology, University of Cincinnati College of

Medicine, Cincinnati, USA.

 

OBJECTIVE:

To determine the effects of dietary inclusion of soy foods on clinical markers

for cardiovascular disease (CVD) and

osteoporosis in normal postmenopausal women.

 

DESIGN:

This was a single open-group prospective clinical intervention. Forty-two normal

postmenopausal women consumed three

daily servings for 12 consecutive weeks of whole soy foods containing

approximately 60 mg/d of isoflavones. Blood and

urine specimens were obtained at baseline and after 12 weeks of dietary

intervention.

 

RESULTS:

Serum and urine levels of individual and total isoflavones increased

significantly (7-19 fold, p O 0.001) from baseline.

A significant increase (9.3%, p < 0.05) in the mean lag-time of low-density

lipoprotein cholesterol oxidation was seen

and was positively correlated with serum phytoestrogens (p < 0.05). Significant

increases were found in mean levels of

high-density lipoprotein cholesterol (HDLc) (3.7%, p < 0.05) and serum

osteocalcin (10.2%, p < 0.025). Significant

decreases were observed in total cholesterol:HDLc ratios (5.5%, p < 0.006) and

mean urinary N-telopeptide excretion

(13.9%, p < 0.02). Urinary excretion of total isoflavones was negatively

correlated with very-low-density lipoprotein

cholesterol, triglycerides, and total cholesterol:HDLc ratios (p < 0.04). No

significant changes from baseline in HDLc

peroxidation, total cholesterol, triglycerides, low-density lipoprotein

cholesterol, very-low-density lipoprotein

cholesterol, bone-specific alkaline phosphatase, follicle-stimulating hormone,

or estradiol levels were observed.

 

CONCLUSIONS:

Dietary inclusion of whole soy foods containing 60 mg/d of isoflavones results

in significant serum levels of

phytoestrogens and reductions in several key clinical risk factors for CVD and

osteoporosis in normal postmenopausal

women. Long-term, placebo-controlled clinical trials are needed to evaluate the

effect of phytoestrogens on the clinical

endpoints of CVD and osteoporosis in this population.

===================

 

There is a lot of bad information around and I really suggest you do research

using original medical research papers

instead of relying on other sources which may have some reason to spread fear

about SOY.

 

That said, Soy does alter estrogen activity in the body and I see little need

for children or nursing mothers to use it.

 

However for postmenopausal women, Soy is a life saver. I love my wife (both now

55) and she get about 75 mg a day of

isoflavones from soy as well a lignans from ground flax. Her lipids, blood and

bone density is like that of a 40 year

old.

Gregg,

I just want to say THANK YOU for your intelligent, reasonable

information about soy. I choose to just ignore the bad press, but I

am glad that you are able to inform others about the truth.

Hi Greg,

You should send an email to Dr. Mercola and the two senior US government

scientists Dr. Daniel Doerge and Dr.Daniel Sheehan let them know they do not

know what they are talking about.

Hi Elaine,

 

With respect that is 3 voices saying No and many, many more saying YES.

 

I did extensive research into phytoestrogens before I let my wife start using

them.

 

Having read 100's of papers, I feel the benefits very much outweigh the slight

risks. Add in iodine rich fish and the

risks get even smaller.

 

Are you yet menopausal?

 

Still learning & researching,

Greg
