This Food Can Make Men Aggressive

That last URL didn't seem to work to well so I'm copying the article.

Didn't see mention of a sample size however so am somewhat suspicious

of the experiment however. :-)

" This Food Can Make Men Aggressive

Men: Beware how much soy you consume. It could change your behavior.

It's long been known that soy is beneficial to women in a number of

ways, but new research from Wake Forest University Baptist Medical

Center indicates the same is not true for men. In fact, a diet rich in

soy isoflavones, especially through the use of soy supplements, can

have marked influences on patterns of aggression and social behavior

in men, reports HealthDayNews. Isoflavones, which are found in soy

protein, are a naturally occurring plant estrogen.

For women, the benefits of a diet rich in soy are numerous. Soy can

reduce the risk of various cancers, as well as osteoporosis,

cardiovascular disease, and some postmenopausal symptoms, such as hot

flashes.

The study: The 15-month study divided adult male monkeys into three

groups, each of which was fed different amounts and types of protein.

One group was given 125 mg of isoflavones daily, while a second group

had half that amount. The third group received its protein from milk

and animal sources. For perspective, isoflavone levels of 125 mg per

day are higher than what is typically consumed by Asians who eat a

soy-heavy diet; however, the amount is comparable to levels found in

many dietary supplements sold in the United States.

The results: " In the monkeys fed the higher amounts of isoflavones,

frequencies of intense aggressive and submissive behavior were

elevated, " the research team wrote in the scientific journal Hormones

and Behavior. " In addition, the proportion of time spent by these

monkeys in physical contact with other monkeys was reduced by 68

percent, time spent in proximity to other monkeys was reduced 50

percent, and time spent alone was increased 30 percent. " Previous

studies have shown no difference in aggression in females given large

doses of soy.

Lead study author Dr. Jay R. Kaplan, a professor of comparative

medicine and anthropology at Duke, says it is often assumed that soy

is only beneficial and never harmful. " There is the thought that what

is good for some is good for all and more is better, " he wrote. But

his research shows that the amount of soy consumed--or the dose of the

soy supplement--does make a difference, as well as the gender of the

consumer.

The Food and Drug Administration approved in 1999 a statement that

says: " 25 grams of soy protein a day, as part of a diet low in

saturated fat and cholesterol, may reduce the risk of heart disease. "

Men, while it's fine to eat a veggie burger or soy sauce, you may want

to consult your physician before taking soy supplements. "

Any male soy eaters out there that are feeling hostile or aggressive?

If so please feel free to vent your thoughts at me. Promise not to

be offended. Don't eat the stuff myself. Just curious.
