Effect of soymilk consumption on serum estrogen and androgen
concentrations in Japanese men.

Nagata C, Takatsuka N, Shimizu H, Hayashi H, Akamatsu T, Murase K.

Department of Public Health, Gifu University School of Medicine, Japan.

Soy consumption has been associated with a reduced risk of prostate
cancer. The mechanism for this association may involve the effect of soy
on the endocrine system. We conducted a randomized dietary intervention
study to determine the effects of soy consumption on serum levels of
steroid hormones in men. Thirty-five men were randomly assigned to
either a soymilk-supplemented group or a control group. The men in the
soy-supplemented group were asked to consume 400 ml of soymilk daily for
8 weeks. The men in the control group maintained their usual diet. Blood
samples were obtained just before the initiation of the dietary period
and thereafter every two weeks for 12 weeks. Changes in hormone
concentrations were analyzed and compared between the two groups using
the mixed linear regression model against weeks from the start of the
dietary period. The mean (SD) soymilk intake estimated from dietary
records during the dietary study period was 342.9 (SD, 74.2) ml in the
soymilk-supplemented group. There was a significant difference between
the two groups in terms of changes in serum estrone concentrations,
which tended to decrease in the soy-supplemented group and increase in
the control group over time. None of the other hormones measured
(estradiol, total and free-testosterone, or sex hormone-binding
globulin) showed any statistical difference between the two groups in
terms of patterns of change. The results of the study indicate that
soymilk consumption may modify circulating estrone concentrations in men.

Hormonal effects of soy in premenopausal women and men.

Kurzer MS.

Department of Food Science and Nutrition, University of Minnesota,
St. Paul, MN 55108, USA.

Over the past few years, there has been increasing interest in the
possible hormonal effects of soy and soy isoflavone consumption in both
women and men. Soy consumption has been suggested to exert potentially
cancer-preventive effects in premenopausal women, such as increased
menstrual cycle length and sex hormone-binding globulin levels and
decreased estrogen levels. There has been some concern that consumption
of phytoestrogens might exert adverse effects on men's fertility, such
as lowered testosterone levels and semen quality. The studies in women
have provided modest support for beneficial effects. One cross-sectional
study showed serum estrogens to be inversely associated with soy intake.
Seven soy intervention studies controlled for phase of menstrual cycle.
These studies provided 32-200 mg/d of isoflavones and generally showed
decreased midcycle plasma gonadotropins and trends toward increased
menstrual cycle length and decreased blood concentrations of estradiol,
progesterone and sex hormone-binding globulin. A few studies also showed
decreased urinary estrogens and increased ratios of urinary 2-(OH) to
16alpha-(OH) and 2-(OH) to 4-(OH) estrogens. Soy and isoflavone
consumption does not seem to affect the endometrium in premenopausal
women, although there have been weak estrogenic effects reported in the
breast. Thus, studies in women have mostly been consistent with
beneficial effects, although the magnitude of the effects is quite small
and of uncertain significance. Only three intervention studies reported
hormonal effects of soy isoflavones in men. These recent studies in men
consuming soyfoods or supplements containing 40--70 mg/d of soy
isoflavones showed few effects on plasma hormones or semen quality.
These data do not support concerns about effects on reproductive
hormones and semen quality.

Soy milk intake in relation to serum sex hormone levels in British men.

Allen NE, Appleby PN, Davey GK, Key TJ.

Cancer Research UK Epidemiology Unit, University of Oxford, Oxford
OX2 6HE, UK.

Soy beans contain high levels of the isoflavones genistein and
daidzein and their glycosides and have been implicated in the prevention
of prostate cancer, possibly via their effects on sex hormone
metabolism. The aim of this study was to assess the relation between
dietary soy intake and sex hormone levels in a cross-sectional analysis
of 696 men with a wide range of soy intakes. Soy milk intake was
measured using a validated semiquantitative food frequency
questionnaire, and serum hormone concentrations were measured by
immunoassay. Multiple regression was used to investigate the association
between soy milk intake, an index of isoflavone intake, and hormone
levels after adjustment for pertinent confounders. Soy milk intake was
not associated with serum concentrations of testosterone, free
testosterone, androstanediol glucuronide, sex hormone-binding globulin,
or luteinizing hormone. These results suggest that soy milk intake, as a
marker of isoflavone intake, is not associated with serum sex hormone
concentrations among free-living Western men.

Eat your soy, boys
A food that's good for girls is good for guys, too

Tuesday, June 15, 2004
By Sally Squires, The Washington Post

Yes, it's true that your wife, girlfriend or significant other has been
eating a lot of soy lately, mainly to boost her female hormones. That
doesn't mean it's bad for you, fella. Instead of pushing aside that soy
milk, go ahead and pour some on your morning cereal. Dig into the soy
burgers at the office cafeteria and the tofu that appears in your
takeout stir-fry.

There is strong evidence that the risk of prostate cancer may be reduced
by eating soy products such as these: plain soy milk and organic soy
non-dairy frozen dessert.

Benefits for men of a diet that includes soy

It turns out that soy, at least in the doses most people will consume it
in food, may be good for guys, too. A growing number of studies suggest
that soy has plenty of health benefits for men -- from lowering
cholesterol levels to protecting against prostate cancer -- and few
downsides.

"Real men should eat soy," said Kenneth Setchell, professor of
pediatrics at the Cincinnati Children's Medical Center, who has studied
soy for 30 years. "Generally, men are put off by soy. It tends to be
sort of a woman's thing. That's a great pity, because the evidence that
soy protects against prostate cancer is quite strong."

While there have been worries that men who consume large quantities of
low-carb soy bread, soy cereal or other soy-filled foods may get a
little too in touch with their feminine sides, research findings have
generally not borne out those fears.

"Soy is a very healthy food," said physician James Anderson, who has
studied soy for 15 years at the University of Kentucky in Lexington and
is convinced enough of its benefits to eat about a dozen servings per
week. "It's very safe."

Most concerns about soy have centered around the fact that it is a rich
source of isoflavones, substances that mimic the effects of the female
hormone estrogen. To determine what these plant-based chemicals might
do, Steven Zeisel and his colleagues at the University of North Carolina
at Chapel Hill fed megadoses of soy to men as part of a recent National
Cancer Institute study.

Nipple discharge, breast enlargement and slight decreases in
testosterone occurred with the megadoses. But "we still couldn't find
anything that was serious, and we went up to doses that are probably 30
times what you could get from normal foods," Zeisel said.

And if you stick with foods rich in soy as opposed to supplements,
researchers say, there's no evidence of harm, unless you happen to be
among the one in every 1,000 people who are allergic to soy.

Not only is soy a rich source of high-quality protein, it also contains
complex carbohydrates that don't raise blood sugar as high as more
processed carbohydrates. It has fiber, folic acid (a key B vitamin),
healthy fat and antioxidants that help protect against cancer.

There's also evidence that soy acts as a probiotic in some people,
promoting growth of healthy bacteria in the gastrointestinal tract that
in turn produce health-promoting substances. It only takes a small
amount of soy to produce health benefits. Less than a handful of soy
nuts, about a fifth of a cup, provides 12 grams of protein, said
Anderson, who keeps a stash near his desk for snacks.

Just resist any urge to eat raw soy. Uncooked soybeans contain a
substance that inhibits trypsin, a key enzyme required for protein
digestion.

I've been experimenting on myself with soymilk for about 2 years. The
most noticeable effect is a persistant mild headache that feels very
similar (but milder) to the "brain freeze" that sometimes accompanies
the consumption of ice cream. I think what's happening is the
emulsified soy oil or fat builds up in the brain. This is not good, and
could lead to serious problems. The effect is noticeable at consumption
levels of 1 pt. per day for a month.

I'm a male who's been off dairy and drinking Soy Milk for over three years
with no negative side effects. It fact, everything is much improved. My
breathing is better, my cholesterol is lower and I've lost weight.

If you're having persistent headaches of the "brain-freeze" variety, you
should have that checked out as soon as possible. Especially if the
headaches are accompanied by blurred vision or dizziness.

It could be something as simple as a food allergy or something as horrendous
as an brain aneurysm. I wouldn't self-diagnose unless you keep an MRI in
your garage.

Also, 1 pint per day? Have you ever heard of moderation?

Limit yourself to 1 cup of soy milk and drink filtered water for the rest of
the day. Anything in excess can be harmful.

Itchy, I had no problems when I ate soy milk, however allergy to soy milk is
common and has the symptoms you described.

Thanks, Randall.
Since soy milk is being marketed as a replacement for cows milk, I
think 1 pint per day may not be an excessive or unusual amount.
